Description

Cellular wheel lock.

The invention relates to a cell wheel lock, which can also be referred to as a discharge and dosage lock.

From DE 201 02 807 U1 a cell wheel lock is known, in which the rotor with the cell wheel is arranged in a cover. The rotor is carried by a rotor shaft, whose two ends are respectively housed in a cover cap on both sides of the rotor cover. On one side, the shaft is passed through the cover lid to the external side and is connected there by a plug-in drive with a drive for rotor drive. On the other side of the cover, the cover lid is movably housed in two rails, the rails extending parallel to the axis of the rotor. For maintenance of the cell wheel lock, the cover lid opposite the actuation of the cover of the cell wheel lock can be released and the cover cover can be removed on the cover rails. The rotor shaft has a tree thread with an external thread, on which a locknut and a guide washer are screwed. The guide washer is housed between sliding washers on the cover cover, the guide washer being fixed between the two axial sliding washers on the cover cover. Therefore, when the cover cover is removed from the cover of the cell wheel lock, the rotor is pulled and removed from the cover. On the drive side, the rotor shaft is inserted into a sliding sleeve, inside which the rotor shaft rotates and through which the rotor shaft is passed outwards. In the cover of the removable cover, the opposite side of the rotor shaft is also housed in a sliding sleeve and is rotatably inserted therein. Between the inner side of the cover lid and the internal axial front side of the rotor a cover pocket is configured, on whose bottom side a discharge deflects the bulk product collected in the cover pocket in a direction towards the side of discharge of the cell wheel lock. In this way, the cover pocket accumulates bulk product that moves between the inner side of the cover lid and the axial front side of the cell wheel in the direction of the bearing side. In addition to the cover pocket, which should prevent the entry of bulk product into the sliding bushing, a shaft seal in the form of a sealing skirt is also provided, which also prevents a movement of material in the direction of the bearing. glide. 25

It is an object of the invention to provide a cellular wheel lock with increased operational reliability.

This objective is met by the features of claim 1 or 29. Advantageous configurations are the subject of the dependent claims.

According to claim 1, a cellular wheel lock is provided, in which a rotor housed on a rotor shaft is arranged on a cover. In the direction towards the axis of the rotor shaft, the cover is closed by a preferably removable cover cover, a first side of the rotor shaft being housed in a first cover cover and a second side of the rotor shaft, in a second cover cover. On one side of the rotor shaft, the rotor shaft is housed in a first bearing bush. Preferably, the second side of the rotor shaft protruding from the rotor is also housed in a second bearing bush. The first bearing bushing is rotatably housed in the first cover cap, the first side of the rotor shaft being arranged without rotation with respect to the first bearing bushing therein. Between the inner side of the bearing bush, that is, at the place where the first side of the rotor shaft is inserted and the outer side of the first side of the rotor shaft, at least one first and second seat are configured . In this regard, the inner side of the bearing bush and the outer side of the first side of the rotor shaft form a seat pairing with a cross-sectional pairing that has a perpendicular travel with respect to the axis of the rotor shaft of the inner side. of the bearing bushing and the outer side of the rotor shaft. The first seat and the second seat are separated from each other in axial direction with respect to the axis of the rotor shaft. Due to reduced tolerances of measurements during manufacturing, the two pairs of seats form at the same time the centering equipment for centering the rotor shaft in the first bearing bush. Therefore, no additional elements or centering components are required.

By the separate arrangement of the seats a support is provided, which opposes a high clamping force to a bending moment that acts, for example, by applying in the rotor in the radial direction on the rotor shaft. That is, a tilting or bending of the rotor shaft is avoided or considerably prevented. Particularly when the second side of the rotor shaft, which is housed in the second cover cover opposite to the first cover cover also in a bearing bush with two seat pairs axially spaced apart from each other, is also substantially excluded with a radial pressure exposure from one side of the rotor a combustion of the rotor or rotor shaft. Nor with a reduced groove measurement between the inner side of the cell wheel lock cover and the tips of the rotor cells or blades can any mutual contact appear. The wear of the rotor or the inner side of the cover and possibly the entry of foreign material into the material to be dosed by the cell wheel lock is thus avoided.

Particularly advantageously, the first seat that is furthest from the rotor has a smaller diameter than the second seat that is closest to the rotor on the first side. This simplifies

considerably the introduction of the first side of the rotor shaft in the bearing sleeve, since during the introduction of the rotor shaft the first front seating surface on the first side of the shaft has a smaller diameter than the second seat that is in the inside of the first cap cover. In this way, the first seat can be passed in the shaft easily and without a high adjustment requirement through the second seat in the bearing bush. 5

Only when the two seat pairings, that is, the first seating surface of the shaft is introduced into the first seating surface of the bearing bush and the second seating surface of the shaft into the second seating surface of the bearing bush, is You have to use an adjustment diligence for a short introduction. This reduces the requirements during maintenance and control of the cell wheel lock when, for example, the first cover cover is removed from the cover and then the first side of the rotor shaft 10 is exposed or when by the first cover cover first remove the cover rotor and then remove the rotor from the first cover cover. In spite of high bearing precision, the requirements for maintenance and service personnel and the risk of damage are thus reduced.

In an advantageous development, the two seat pairings are displaced from each other in axial direction in such a way that during the introduction of the rotor shaft in the first bearing bush 15 it grabs one of the two seat pairings and only with the Additional introduction with axial separation grabs the second of the seat pairings. For example, this axial displacement of the contact between the two seat pairings amounts to between 0.2 and 2 mm, preferably between 0.3 and 1.7 mm, between 0.5 and 1.5 mm, between 0 , 8 and 1.3 mm. or about 1 mm. Advantageously, in this regard, the internal seat pairing (second seat pairing), which is closest to the rotor, first and then 20 of the axial displacement of the contact, the first external seat pairing.

 According to one configuration, there is a radial separation between the outer side of the rotor shaft and the inner side of the rotor on the first side of the rotor shaft after the complete introduction of the rotor shaft into the first bearing bush. First bearing bushing. In this way the introduction of the first side of the rotor shaft into the first bearing sleeve is further simplified, since it is guaranteed that during the introduction of the first side of the rotor shaft along the entire length of the first side there is sufficient clearance for the two seat pairings to enter each other.

 In a very particularly advantageous configuration, the insertion depth or insertion depth of the first side of the rotor shaft in the first bearing bush is determined by a flat stop. The stop is formed by a front edge or stop surface on the first side of the rotor shaft and a (counter) 30 stop surface on a stop member housed in the first bearing bushing. Preferably, the two abutment surfaces are paired with each other, such that a large contact surface is obtained, which excludes a deformation of the surfaces. Particularly, in this respect, the abutment surfaces mutually supported of the rotor shaft and the abutment element are configured perpendicularly with respect to the axis of the rotor shaft, such that in comparison with a cone during axial surface fixing No deformation can occur during the fastening against the support surface of the front side 35 of the abutment element. Even with a disassembly and multiple assembly of the rotor support in the first cover of the cover there are no deformations and lack of roundness. The bearing surface of the front side in the rotor shaft and the corresponding bearing surface in the abutment element, whose surfaces are perpendicular to the axis, can occupy the entire cross-sectional surface of the rotor shaft or only a part of the cross-sectional surface. For example, the bearing surface on the rotor shaft may be configured as an annular shoulder on the front side of the rotor shaft or axially retracted on the rotor shaft.

 Advantageously, the stop element can be adjusted with respect to the first bearing bushing in axial direction. The stopper element may be housed in the first bearing bush itself (preferably) or in the first cover. An adjustment device is provided, whereby the axial end location of the first side of the rotor shaft 45 in the first bearing sleeve can be graduated and axially modified or adjusted. In particular, the axial location of the abutment element or its abutment surface with respect to the first bearing bush can be fixed or determined by means of a locking device. Advantageously, the blocking equipment is part of the adjustment equipment and / or the blocking equipment blocks the stop element with respect to the first cover cap and / or with respect to the first bearing bushing. By means of the adjusting equipment, therefore, the axial location of the rotor can be fixed with respect to the first cover 50 of the cover and, therefore, also with respect to the cover of the sluice. On the part of the factory, therefore, the exact location of the rotor can be set by a unique adjustment of the stop element.

In additional maintenance and service work, a reproducible final location of the rotor inside the cover is guaranteed due to the predefined axial location of the stop element. In this regard, it is not necessary to perform a new rotor adjustment in each cutting process of the cell wheel lock. In this way, much smaller axial separations (groove measurements) can be maintained during the construction of the cell wheel lock between the rotor and the cover caps or between rotor and cover (in the event that the rotor can be removed , for example, only from one side of the deck).

 Particularly advantageously, between the axial front side of the rotor or between the side of the rotor and the inner side opposite this front side of the first cover of the cover is an air groove seal, which is 60

preferably exposed on the bearing side to a washing means. The washing means is preferably air, however, it can also be an inert gas and / or noble gas or any other washing means that is compatible with the material to be dosed by the cellular wheel lock. During cleaning of the cell wheel lock, particularly in a CIP cleaning (Cleaning In Place), instead of or in addition to the washing means, a cleaning means can be passed through the air gap seal. For example, a cleaning liquid, such as an acid, alkaline, alcoholic, surfactant or any other cleaning liquid. When the washing medium is referred to hereafter, a cleaning medium (of this type) can be used correspondingly during the cleaning process.

The air gap seal is a separation between the front side and the inner side of the first cover cover with a predefined groove measurement, the groove measurement being preferably <1/10, 1/20, 1/40, 10 1/60, 1/80, 1/100 mm and preferably> 1/100, 1/80 or 1/60 mm. Particularly the combination of abutment elements with adjustment equipment with the air groove seal ensures that an air groove gasket with a precisely adjustable groove measurement can be provided. Preferably, the groove measurement is greater than 0.05, 0.1, 0.15, 0.20 or 0.5 mm and / or less than 1 mm, 0.5 mm. or 0.1 mm.

According to a configuration, a control channel is provided between the rotor and the bearing (s) of the first bushing of 15 bearing, which is driven from the bearing zone or the intermediate zone between the bearing (s) and the rotor to the external side of the first cover lid. In the event that, for example, the bulk product discharged by the cellular wheel lock travels between the rotor and the first cover cap along the rotor shaft or along the first bearing bushing in the direction of the bearing, through the control channel it is possible to determine this contamination. In the same way it is avoided that an unintended exit of this type of material continues to leave in the direction towards the bearing, leaving through the control channel towards the external side. The control channel is seen axially between the rotor and the bearing of the bearing bushing and preferably has a path in the mounted state of the cell wheel lock from the rotor shaft or bearing bushing downwards, in such a way that an automatic expulsion of the wrongly conducted material is performed. Preferably, the control channel comprises a channel that surrounds the rotor shaft or the bearing bush on its outer periphery, such that around it material can be removed from the bearing sleeve or rotor shaft.

Preferably, seen axially, at least one sealing element is provided between the control channel inlet in the bearing shaft or in the rotor shaft and the bearing (s) of the first bearing sleeve. The at least one sealing element further prevents an entry of material in the bearing (s).

Advantageously, the bearing bushing is rotatably housed on or in the cover by at least two bearings, particularly ball bearings, bearings or the like. The at least two bearings are preferably separated from each other axially with respect to the axis of the rotor shaft (including an adjacent arrangement) and thus cause a high counter force to be applied with a bending moment on the rotor shaft. -force. As already described above with respect to the two seat pairings, in this way a combustion of the rotor is counteracted. Particularly, the bearing bushing is rotatably housed on or on the cover by a double bearing without clearance and / or by an oblique edge bearing without clearance. This minimizes or excludes an axial clearance of the bearing bushing with respect to the first cover cap.

 According to a particularly advantageous configuration, a first sealing device is arranged between the first cover cover, the internal area of the axial front side of the rotor and the first bearing bush or the first side of the rotor shaft. The first sealing equipment prevents the entry of material from the interior space of the cell wheel lock in the direction of the support of the first side of the rotor shaft in the first cover cover. In this regard, the first sealing equipment seals on one side between the first cover cover and the first bearing bush or the first side of the rotor shaft and, on the other hand, between the front side of the rotor and the first sleeve of bearing or the first side of the rotor shaft. The inner zone of the axial front side is the axial front side of the rotor, which is located in the area around the bearing shaft. Four. Five

 Advantageously, the sealing equipment comprises a washing chamber configured in the first cover cover, to which a washing means can preferably be provided from the external side of the first cover cover (compare with the above). Advantageously, a sealing ring is housed on the outer side of the first bearing bush or on the first side of the rotor shaft, which is arranged at least partially in or on the washing chamber. Thus, on the rear side of the sealing ring, the washing medium can be distributed in the interior of the washing chamber, such that the sealing ring on the rear side is exposed to a slight overpressure of the sealing means. washing and an opposite flow of the washing means prevents transport of the material from the cell wheel lock in the direction of the bearing.

 Advantageously, an air gap is formed between the outer side of the sealing ring and the inner side of the washing chamber or the inner side of the first cover lid, through which the washing means 55 is discharged from the wash chamber in the direction of the internal space of the cell wheel lock. Due to the air gap, a direct contact of the sealing ring on the inner side of the washing chamber or the inner side of the first cover lid is avoided and no wear of material of the sealing ring occurs due to a contact abrasive with rotor rotation. Preferably, the groove measurement between the cover cap and ring of

Sealing amounts to at least 0.05 mm, 0.1 mm, 0.15 mm, 0.2 mm or 0.3 mm. and / or at most 1 mm, 0.7 mm, 0.5 mm. or 0.3 mm.

According to a configuration of the first sealing equipment, the sealing ring is housed by an immobilization and / or sealing element in the first bearing bush or on the first side of the rotor shaft and / or is sealed by an element of immobilization and / or sealing against the first bearing bush or the first side of the rotor shaft. That is, the sealing ring, instead of in the bearing bush as shown in the following concrete configuration, can also be housed on the first side of the rotor shaft. The immobilization element holds the sealing element on the first bearing bushing or on the first side of the rotor shaft, such that the sealing ring rotates during rotation of the rotor with the bearing bushing or the rotor shaft. The sealing element prevents a passage of material between the sealing ring and the first bearing bushing or the first side of the rotor shaft. Alternatively or additionally, between the sealing ring and the axial front surface of the rotor is provided a sealing element, particularly a sealing element disposed on the outer periphery of the sealing ring, which prevents a transport of material between the front side of the rotor and sealing ring.

Advantageously, the sealing element and a recess in the sealing ring are configured in such a way that between the sealing element and the sealing ring there is formed a drag closure so as to act in the axial direction. This closing with a drag means that during maintenance and inspection work on the cell wheel lock, a slip out of the sealing element of the recess in the sealing ring is avoided. Preferably, the recess is made in the sealing ring and the sealing element has a preferably peripheral projection, which fits into the notch. Particularly advantageous, the peripheral projection is a molding or crown, which can be included or included in the notch.

Advantageously, the immobilization and / or sealing element is designed in such a way that axial displacement of the sealing ring on the first bearing bushing or the first side of the rotor shaft is possible.

Particularly advantageously, at least one spring element is disposed between the sealing ring and the first bearing bush or the first side of the rotor shaft, which presses the sealing ring against the axial front side of the rotor. Particularly a disc spring is used as a spring element. The axial pre-tension or axial compression of the sealing ring against the front side of the rotor reinforces the compression force of the sealing element between the sealing ring and the front side of the rotor and the spring also allows axial displacements of the sealing ring on the first bearing bush or the first side of the rotor shaft. 30 This is advantageous when the rotor shaft is axially adjusted inside the first cover cap, such that the spring element even with axial displacement of the rotor shaft guarantees a seal ring contact on the front side of the rotor.

The support of the first side of the rotor shaft in or on the first cover cap and its configuration has been described above. The support can be applied correspondingly on the second bearing side of the rotor, then the second side of the rotor shaft is housed in or on the second cover cap. All configurations and embodiments described above can also be applied unlimitedly for this second bearing side.

 In the configuration with respect to the first bearing side, preferably no connecting element and adjustment device are provided on the second bearing side, so that the adjustment of the rotor in the interior of the wheel lock cover Cell phone is done by the stop and the adjustment equipment on the first bearing side. Preferably and as a modification, alternatively or additionally, the second side of the rotor shaft and / or the second bearing bush is passed outwardly through the second cover cover towards the outer side of the cell wheel lock. In particular, a drive for the rotor can be connected or connected with the second bearing bushing or the second side of the rotor shaft. Four. Five

 Preferably, the drive has a motor, which is advantageously carried by the bearing bushing and / or the second side of the rotor shaft. In this case it is advantageous if the engine is fixed by a torque support (torque barrier) against a torque with respect to the cover of the cell wheel lock. This does not require any clutch or coupling element between the motor shaft or drive output shaft and drive shaft or rotor bearing bushing, which has to compensate for a shaft displacement 50 (parallel displacement and / or angular).

 In a further configuration, by means of a form-shaped closure between the second side of the rotor shaft and the second bearing bush, a dragging device is configured, which protects the rotor shaft in the second bearing sleeve against torsion. In this regard, the second bearing bushing is passed outwards through the second cover cap and serves to drive the rotor. In this respect, the dragging equipment prevents twisting between the second side of the rotor shaft and the second bearing bushing.

 According to claim 29, a cellular wheel lock is provided, in which between the first cover cap, the internal area of the axial front side of the rotor and the first bearing bushing or the first side of the shaft of the

rotor is arranged a first sealing equipment. The first sealing equipment prevents a discharge of material from inside the cell wheel lock in the direction of the bearing in or on the first cover cap. The first sealing equipment has a washing chamber configured in the first cover cap and a sealing ring housed on the outer side of the first bearing bushing or the first side of the rotor shaft. The sealing ring is arranged in or on the washing chamber and by means of a washing means (see above) 5 supplied to the washing chamber a flow of the washing medium between the washing chamber and the sealing ring is caused in the direction into the interior space of the cell wheel lock. This stream of washing medium is oriented against a flow of material from the inner side of the cell wheel lock in the direction of the bearing and thus prevents a transport of material from the inner space of the cell wheel lock in direction towards the bearing. 10

 At the same time, by means of this washing current, a deposit of material in dead spaces of the cell wheel lock is avoided, in such a way that with a change of load or a change of material a contamination of the next material to be discharged is avoided by means of cell wheel lock for the material used previously.

 The cell wheel lock according to claim 29 is an alternative solution to the cell wheel lock described above according to claim 1. All the configurations and advantages described above with respect to claim 1 are also they apply in this case, any combination and sub-combination of the characteristics described above in the cell wheel lock according to claim 29 can be used correspondingly. For example, in the cell wheel lock according to the claim 29 a support of the first bearing bush can also be used in the first cover cap by means of two seats, as described above in claim 1. Therefore, reference is made in its entirety to the above. In claim 29, the objective is solved because a sealing device with a sealing ring housed in the first bearing bush or the first side of the rotor shaft is used. The advantages and configuration have already been described above with respect to a configuration of claim 1.

 With reference to the attached drawings, an embodiment of the invention is explained in more detail. It shows 25:

Figure 1 shows a cell wheel lock 2 from the side in the closed state with the drive 14 coupled to the cell wheel lock 2. In the cover 4 of the cell wheel lock 2 an upper flange is coupled from the upper side 10 and from the lower side, a lower flange 12. During operation, the bulk product to be dosed by the cellular wheel lock 2 is supplied from the upper side through the upper flange 10 and is emitted in dosage form by the bottom flange 12 down. The lower flange 12 is connected, for example, with a tubular duct transport system and flows directly into a mixing vessel or the like. The front and rear sides of the cell wheel lock 2 are configured by the side walls of the cover 4. The side surfaces located in the direction of the rotor axis of the cell wheel lock 2 are closed on the right side (as is shown in Figure 1) by a first cover cover 6 and on the left side, by a second cover cover 8. 10

 The drive 14 for driving the rotor of the cell wheel lock comprises an electric motor 15, which is connected by a transmission 16 with a drive shaft 42 (Figure 2). In the second cover cover 8 a console 18 (or molded in the second end cap 144 (Figure 4)) is opened, in which a fastener 20 is arranged. The fastener 20 protrudes radially with respect to the axis of the rotor shaft and it houses an extension 22 connected to the transmission 16. In the illustrated embodiment of the cell wheel lock 2, the drive 14 is housed by the drive shaft 42 in the second bearing 40 (Figure 2). The torque that appears during rotor drive is transmitted by drive 14 by extension 22 and fastener 20 to the second cover cover 8. Therefore, it is not necessary to provide a compensation clutch between the rotor shaft 32 and the transmission shaft 42 leaving the transmission 16.

 Additional equipment for supplying the cell wheel lock 2 or 20 monitoring and supply equipment for drive 14 is housed in the console 18. For example, a compressed air device 24 with a compressed air regulator or adjuster and a regulator or air quantity adjuster. In the first and second cover cover 6, 8 a compressed air connection 26 is respectively provided, by which compressed air is supplied from the outside as a washing means for washing the annular groove 106 (see below). A cleaning medium is thus supplied during the washing process (compare with the above). 25

     Figure 2 shows a cross-sectional view through the cell wheel lock 2 as shown in Figure 1, in which, however, the first cover cover 6 has been released from the cover 4 and with the first cover cover 6 a rotor 30 has been partially removed from the cover 4 of the cell wheel lock 2. In the rotor 30, seen in axial direction, rotor blades or cells 31 are provided which have a star-shaped path radially towards the outside, between which the bulk product supplied from above is discharged in a rotational manner 30 from the rotor. The rotor blades 31 are supported by a rotor shaft 32, which to the right and left of the rotor blades 31 has a first shaft end 34 shown in Figure 2 on the right and a second shaft end 36 represented at the left. The first shaft end 34 is housed in a first bearing 38, which is disposed in the first cover cap. The second shaft end 36 is housed in a second bearing 40, which is disposed in the second cover cover 8. By means of the form-shaped closure, it is configured between the second end of the shaft 36 35 and the end that is in the cellular wheel lock 2 of the drive shaft 42 (compare with the second bushing 48) a drag 44 (compare with Figure 5), which couples the second end of the shaft 36 with torsional resistance to the drive shaft 42 or bushing 48 The drive shaft 42 is coupled by means of a drive drag 43 to a plug socket not shown in the transmission to the transmission 16.

The first shaft end 34 is inserted into the first bearing 38 in a first bearing sleeve 40 with a plug 46 when the cellular wheel lock 2 is mounted. The second shaft end 36 is inserted into the second bearing 40 in a second socket 48, such that the rotor shaft 32 is carried by the two bushings 46, 48.

Figure 3 shows a detailed cross-sectional view of the first bearing 38 in the first cover cover 6. In the shown state, the first cover cover 6 is screwed onto the cover 4 and the first shaft end 34 is inserted completely in the first bushing 46. Between the first shaft end 34 and the first bushing 46, two adjustment pairs are configured, with a first adjustment match 50 or internal being located at the first end of the shaft closer to the rotor 30 than a second coupling external adjustment 52.

An adjustment pairing is formed by a pairing of surfaces between the outer side of the first 50 tree end 34 and the inner surface of the first bushing 46. Each of the adjustment pairs 50, 52

center the first shaft end 34 with respect to the first bush 46. By the axially separated arrangement of the adjustment pairs 50, 52, a clamping moment or lever counteracts a bending or an inclination of the rotor shaft 32.

The diameter of the external adjustment match 52 is smaller than the diameter of the internal adjustment match 50. In addition, in an intermediate section 54, which is between the two adjustment matches 50, 52, the external diameter of the first shaft end 34 is smaller than the internal diameter of the corresponding area of the first bushing 46 (when the first shaft end 34 is fully inserted in the first bushing 46).

Each of these measures and particularly these measures together simplify the assembly and disassembly of the cell wheel lock 2 during maintenance work. During assembly, the front end of the first shaft bearing 34 can be introduced without resistance and without particular adjustment and alignment requirements in a simple way in the first bush 46, to an axial depth, which is then the outer surface of the first tree end and the inner surface of the first bushing, which make up the external adjustment pairing 52, fit together.

 The separations between the adjustment pairings 50, 52 in the bush and at the first end of the shaft can be dimensioned in such a way that an introduction of the surfaces of the first adjustment match between them simultaneously introduces the surfaces which they configure the external adjustment pairing 52. However, preferably, the separations of the adjustment pairing 50, 52 are shifted in such a way that during the introduction of the first end of the shaft 34 in the first bush 46 first fit the adjustment surfaces of the internal adjustment pairing 50 together and after a partial introduction of the adjustment surfaces of the internal adjustment pairing with axial displacement fit together the 20 adjustment surfaces of the external adjustment pairing 52. The displacement axial contacting of adjusting pairings 50, 52 is preferred probably about 1 mm. Other advantageous axial travel distances have been indicated above in the introductory part.

 Preferably, on the respective front side of the surfaces for internal adjustment pairing 50 and / or external adjustment pairing 52 a chamfer is respectively configured over an axial distance, which simplifies the introduction of pairing surfaces together of adjustment. As shown in Figure 3, these introduction chamfers can also be configured only at the first end of the shaft or, alternatively or additionally, also in the transition zones between the differences in diameter on the inner side of the first bush 46.

 Between the outer terminal zones of the first shaft end 34 and the first bush 46 there is provided a shaft adjusting device 55. The first shaft end 34 is fixed by means of a screw 56 in the first bush 46. In this regard, the screw 56 tightens the front side of the first shaft end 34 against a stop surface 60 configured in a stop element 61. In the embodiment shown, the stop element 61 is at the same time an adjustment screw 58 housed in the first bushing . By torsion, the adjusting screw 58 can be adjusted in axial direction with respect to the first bushing 46 in such a way that by the interaction of the stop surface 60, the adjusting screw 58 and the stop surface of the front side at the first shaft end 34 a defined depth of penetration is set, precisely predetermined of the first shaft end 34 at the first bush 46, which can be adjusted in turn by means of the adjustment screw 58. Even with a disassembly and Multiple mounting of the cell wheel lock 2 ensures that an axial adjustment made once of the rotor 30 can be produced reproducibly on the first cover cover 6 and, therefore, with respect to the cover 4 of the lock of 40 cellular wheel 2. To maintain an adjustment made once a locknut 62 is additionally provided, with which the turning position of the adjusting screw 58 is fixed inside the first socket 46.

 Preferably, the abutment surface 60 on the adjusting screw 58 or the abutment member 61 and the abutment surface correspondingly matched on the front side of the first shaft end 34 have a perpendicular travel with respect to the axis of the rotor shaft 32 , so that there are no lateral deformations or widening of the surfaces. The adjusting screw 58 has an external thread, which interacts with a threaded bushing section 64 at the outer end of the first bushing 46. The external front side of the first cover cover 6 is closed by a front plate 66, where the process Adjustment for axial adjustment of the rotor shaft 32 or rotor 30 in the second bearing 40 after removal of the front plate 66 is exposed for graduation.

 The first bushing 46 is rotatably housed inside the first cover cover 6 by a first 50 ball bearing 68 and a second ball bearing 70. The first and second ball bearing, 68, 70 together form a pair of oblique-edge bearings and are fixed together to a stop, to avoid an axial clearance of the first bearing bushing 46 inside the first cover cap 6 and, therefore, an axial clearance of the rotor 30 in the inside the cover of the cell wheel lock 4. The first ball bearing 68 is supported with its internal front surfaces of the outer periphery in a first stop 74 of the cover of the cover 6 and in the inner periphery 55 in a second stop 76 in the first bushing 46. An end cap 78 is fixed by screws in the axial direction against the first cover cap. The outer front side of the second ball bearing rests on the outer periphery in a third stop 80 which is inside the end cap 78 and on its inner periphery a safety washer 82 is supported. The safety washer 82 is tensioned by means of a fixing nut 84 against the inner periphery outside the second ball bearing 70 in such a way that on the part of the

factory, the axial clearance provided in the pair of oblique-edge bearings between the opposing inner peripheral rings of the two ball bearings 68, 70 is eliminated by the fixation and the two ball bearings 68, 70 are placed in abutment. This eliminates or substantially reduces the existing axial bearing clearance, usually in a ball bearing. On the outer periphery, the opposite front sides of the ball bearings 68, 70 are positioned on the part of the factory without play forming a stop by the axial protection between the third stop 80 of the 5 terminal cap 78, which rests against the outer edge of the second ball bearing 70, and the second stop 76, which rests against the outer edge of the first ball bearing 68.

 In the area between the rotor 30, the inner side of the first cover cap 6 and the outer side of the first bush 46 is provided a groove seal arrangement 90. The slot seal arrangement 90 is formed by a rinse space 92 partially configured in the first cover lid 6, in which a washing medium (compressed air, as mentioned above) can be expanded. The rinse space 92 is sealed to the inner front surface 94 of the rotor by a sealing ring 96. Between the outer periphery of the sealing ring 96 and the inner front surface 94 of the rotor a gasket 98 is arranged. The gasket 98 prevents a penetration of material discharged by the cell wheel lock 2 between the area between the inner front surface 94 and the sealing ring 96. 15

 The sealing ring 96 is sealedly sealed by an immobilization joint 100 and by immobilization pressing on the outer side of the first bushing 46, such that the sealing ring 96 rotates with the first bushing 46 and, therefore, with the rotor 30. Therefore, there is no relative movement in the immobilization joint 100 and in the joint 98, such that no abrasion and wear occurs in that place. The sealing ring 96 is pressed by a spring washer 102 or a disc spring in the axial direction 20 away from the first sleeve 46 towards the inner front surface 94 of the rotor. In this regard, the spring washer 102 ensures that the seal ring 96 interacts with the locking joint 100, that during the adjustment by means of the shaft adjusting device 55, during the axial adjustment despite the axial displacement of the rotor shaft 32 with respect to the first bushing and, therefore, the displacement of the rotor with respect to the first bushing is pressed securely against the internal front surface 94. 25

 In the groove seal arrangement 90 the single seal, in which during the rotation of the rotor 30 a relative movement of the sealing surfaces affects each other, is formed by an annular groove 106. The annular groove 106 is between a surface outer of the sealing ring 96 and an internal surface in the first cover cover 6, which joins the rinsing space or that is part of the rinsing space (when it is understood that the sealing ring 96 is horizontal inside the space rinse 92). In this regard, a side groove surface 108 of the annular groove 106 is formed by an internal surface of the first cover lid 6. Since the annular groove 106 configures a groove joint pierced by means of washing, they do not occur sliding surfaces with each other and a minimum separation between surfaces moved relative to each other by the minimum cleavage measure is guaranteed. The minimum groove measurement preferably amounts to at least 1/100 mm, 1/80 mm, 1/50 mm, 1/20 mm, 1/10 mm or 1/5 mm. 35

 From the outer side of the first cover cover 6 is supplied by the compressed air connection 26 and the washing gas channel 104 that joins the same compressed air to the rinsing space 92, such that due to overpressure between the rinsing space 92 and the internal space of the cell wheel lock flows a stream of continuous gas from the washing medium (from the bearing side in the direction of the inner side of the cell wheel lock 2). This prevents a penetration of material into the rinsing space. A transport of material from the internal space of the cell wheel exclusive in the direction of the first bearing 38 is avoided. Continuous washing of the annular groove 106 with a suitable washing means results in a microbiologically harmless slit. Also, by joining the annular groove 106 of the groove seal arrangement, an annular groove 126 is also formed in the shape of a disk, which has a radial path. In this regard, the washing means flowing through the annular groove 106 flows between the inner side of the cover cap and the opposite axial front side 45 in the inner area of the rotor 30 through an outward groove in direction to the rotor cells and the internal space of the cell wheel lock. The groove measurement of the radial annular groove is obtained by the high precision adjustment made possible due to the shaft adjustment equipment 55 of the rotor 30 in the cover 4, which allows the use of minimum axial distances between the front side of the rotor and the first cover cover 6. Correspondingly, an annular disc groove 50 is formed between the second cover cover 8 and the front left side of the rotor 126 (Figure 4), which can also be adjusted by the adjustment equipment 55 in the first cover cover 6.

 In the rinsing space 92, a slight overpressure is adjusted during operation by means of the washing means. In order to avoid an exit of the washing means (possibly of the cleaning means) in the direction of the bearings 68, 70, the radial retaining rings 110, 112 seal the rinsing space on the rear side (in a manner opposite to the gasket slit). As an additional measure for the control and / or the avoidance of a transport of material that possibly takes place from the internal space of the cell wheel lock in the direction of the bearings (pair of oblique-edge bearings) is provided around the first bearing 46 between the groove seal arrangement 90 and the oblique edge bearing 68, 70 an annular channel 122, which flows into a discharge channel 120. The discharge channel 120 leads from the lower side of the annular channel 122 to the external side of the first cover cover 60 6, so that finally the material transported to the annular channel 122 is discharged through the discharge channel 120.

 The pair of oblique-edge bearings 68, 70 is disposed between two radial seal rings 113, 114. The radial seal rings 113, 114 form a grease chamber with each other to retain a lubricant for bearings 68, 70. In addition to contamination by lubricant outlet of the bearings 68, 70 towards the outside also prevents contamination of the bearings 68, 70 by penetration of contamination from the outside into the bearings 68, 70.

 Figure 4 shows an enlarged detailed view of the second bearing 40 on the left side of the bearing in the second cover cover 8. The second end of the shaft 36 is housed in the second sleeve 48, which is configured so that it guides through of the second cover cover 8, the outer shaft of the second bushing 48 configuring the drive shaft 42, to which the transmission 16 is coupled. As in the first bearing 38 in this case a groove sealing arrangement 90 and a disk-shaped annular groove 126. With respect to the construction and the elements of the groove seal arrangement 90 (126) in the second cover cover 8 8 reference is made to the groove seal arrangement 90 (126) in the first cover cover 6. The same and with the same function elements are provided with the same references and are not described again here (essentially).

 Corresponding to the internal and external adjustment pairing 50, 52 between the first shaft end 34 and the first bush 46 is configured at the second shaft end 36 and the second bush 48 also an internal seat pairing 130 and a pairing of external seat 132. Among these there is in turn an intermediate section 54, the configuration and function of the internal and external seat pairing 130, 132 and of the intermediate section 54 is as in the first tree end 34. In a modified manner with respect to the first shaft end 34, it is further configured at the second shaft end 36 additionally by a drag-shaped closure of the conveyor 44, in which the shaped surface with a drag seat 44a of the second shaft end 36 in the 20 area of the conveyor 44 and the shaped surface with a drag seat 44b of the second bushing 48 in the area of the conveyor 44 are respectively configured c on dragging each other in the perpendicular cut with respect to the shaft of the shaft, in such a way that between the second bushing 48 and the rotor shaft 32 a twist lock is guaranteed - compare with the outer periphery flattened laterally at the second end of tree 36 in the area of the conveyor 44 as shown in Figure 5. 25

 As in the case of the first bearing 38, also in the second bearing 40 the second bushing 48 is housed by two ball bearings. In this regard, a third ball bearing 140 and a fourth ball bearing 142 together form a double bearing, in which the ball bearings 140, 142 are arranged axially spaced from each other and are protected from each other. In this case, it is not necessary to fix the bearings 140, 142 forming a stop as in the pair of oblique-edge bearings 68, 70, since the axial clearance of the rotor 30 is guaranteed by the unsupported support of the first end of shaft 34 in the first bearing 38. Between the ball bearings 140, 142 a distance capsule 146 is inserted. The fourth ball bearing 140 is supported by a stop or molding configured in the second cover cover 8 and a stop or molding formed on the outer side of the second bushing 48. A second terminal cap 144 fixes the external housing of the third ball bearing 140, such that the double bearing is fixed between the second cover cap 8 and the second terminal cap 144. By means of a second front plate 35, which is pressed against the second end cap 144, the fourth ball bearing 142 in support is protected against the third ball bearing 140. In this case, no retaining rings are required. radial, such as radial seal rings 113, 114, in the first bearing 38, since the ball bearings 140, 142 are configured as self-sealing closed bearings with an own lubricant reservoir.

In the second bearing 40, other radial seal rings 116, 118 are provided between the slit seal arrangement 90 and the double bearing 40, 142, which in turn prevent a loss of the washing medium from the rinse space 92. As in the first bearing 38, an annular channel 122 and a discharge channel 120 are also provided in the second bearing 40, which collects material that has exceeded the groove seal arrangement 90 and the radial seal rings 116, 118 and transports it towards the external side, so that at the same time a function control is also guaranteed. Four. Five

Figure 5 shows in a side perspective view the cross-section through the cell wheel lock according to Figure 2.

Figure 6 shows a further enlarged detailed view of Figure 4, in which in this case the second tree end 36 has been removed from the second bushing 48 (or inserted into the second bushing 48) until in the pairing of inner seat 130 the seating surfaces 130a, 130b still fit together, 50 while the chamfer disposed on the front side of the outer seat pairing 132 at the second shaft end 36 slides outwardly straight from the seat pairing externally 132. Conversely, during the introduction of the second shaft end 36 in the second bush 48 first, the inner seat matching surfaces 130a, 130b fit centrally with each other, before they fit in with an additional introduction each other surfaces 132b, 132a of external pairing 132. 55

For axial separation of the displacement of the contacting of the seat pairings 130, 132, the corresponding advantageously applies as for the adjustment pairings 50, 52 in the first bearing 38. The paired surfaces of the internal seat pairings 130 indicated in this document with the internal seating surface 130b in the second bushing 48 and the external seating surface 130a at the second shaft end 36. The surface matching of the external seat matching 132 is indicated 60

by the internal surface 132b in the second bushing 48 and the external surface 132a at the second shaft end 36. In addition, in Figure 6, the rotation closing engagement of the drag 44 is indicated by the shaped surface with a drag seat external 44a configured without rotation symmetry at the second shaft end 36 and the surface with internal drag seat 44b paired with this in the second bushing 48. In this regard, the conveyor 44 is between the seat pairings 130 and 132, the diameter of the surfaces 44a, 44b being smaller than the diameter of the surfaces 130a, 130b.

 Figure 7 shows in cross section a detailed view of the joint or joint surface between the upper side of the cover 4 and the upper flange 10. A flange gasket 160 is inserted into a joint groove 162 and seals the joint between the upper flange 10 and the cover 4 towards the outer side. The joint groove 162 is formed in a trapezoidal shape, the distance of the joint surfaces between the flange 10 and the cover 4 being in the inner edge of the flange joint 10 160 smaller than in the outer side of the flange joint 160 Thus, the flange gasket 160 is pressed more intensely during the tightening of the joint site on the inner side and an extension of the joint material from the inner side to the outer side is possible. This prevents bulging of the joint into the internal space, which in turn prevents dead space or difficult to clean edges. Additionally, the life of the gasket 160 is extended by its useful life with repeated assembly and disassembly. fifteen

 Figure 8 shows a configuration of the support according to Figure 3. An extensive description is omitted herein, since most of the elements are identical to the elements represented in Figure 3 and have the same function as the same. . As modification of the embodiment shown in Figure 3, instead of the front plate 66, a cup-shaped lid 170 is provided, which includes an axially extending cylindrical wall, while the end cap 78 of Figure 3 is used as terminal cap 172 20 axially shortened. Due to the axial shortening of the terminal cap 78, in maintenance and adjustment work, access to the locknut 62 is simplified, since it does not deepen (both) in the terminal cap 78 and in Figure 3.

 Figure 9 shows an enlarged detailed view of the cutout D of Figure 8. It can be seen that in this configuration in the slit seal arrangement 90 instead of the joint 98 with rectangular cross-section 25 a joint 174 with a molding is used 176 applied on the inner periphery of the sealing ring 96. The groove of the sealing ring 96 has a notch and houses the second stop 76 with the notch. If the cell wheel lock is disassembled for maintenance or inspection work, a fall towards the outside of the gasket 174 due to the drag-on closure so that it acts in an axial direction between the recess in the sealing ring 96 for the gasket 174 and the gasket 174. This effectively prevents accidental loss. of the board 174. 30
