Definitions

Mobile compressors are used, for example, on construction sites or for craft activities in which compressed air is required for connected compressed air tools.
a frequently used type of compressor is the reciprocating compressor, in which air is sucked into one or more cylinders, compressed by a piston and discharged again as compressed air.
the amount of air supplied by reciprocating compressors is usually adjusted by regulating the drive speed of the compressor driving machine to the respective compressed air demand.
a compressor with a compressed air sensor is shown, depending on the measured value, the speed control of a reciprocating compressor runs.
Piston compressors have no continuous compressed air discharge due to their pulsed operation, but generate compressed air in pulses. Therefore, a certain volume of compressed air buffer is usually kept in reserve to dampen the compressed air pulses through the compressor. This buffer volume is conventionally kept in separate storage container, so that a compressed air consumer connected to the storage tank compressed air with uniformly high pressure can be provided.
the publication DE 10 2009 052 510 A1 For example, it deals with a variable speed piston compressor which has a lightweight and compact plastic air tank.
a compressor comprising an engine, a drive shaft connected to and driven by the engine, a crank drive connected to the drive shaft, at least one compressed air generating device driven by the crank drive, and adapted to To generate compressed air, a crankcase having an inner chamber wall in the form of a hollow body which receives the drive shaft at least partially, a radially spaced from the inner chamber wall radially to the drive shaft outer chamber wall, an end wall, and a partition, and a compressed air storage tank, which is designed is to receive compressed air generated by the compressed air generating device, wherein the compressed air storage tank through the inner chamber wall, the outer chamber wall, the end wall and the partition wall is formed.
a basic idea of the invention is to embed the accumulator for compressed air generated by the compressor in the crankcase of the compressor by the space around the drive shaft is used around. This results in a great advantage that can be dispensed with a separate storage tank, which in turn contributes to a significant weight and cost savings.
the entire construction of the compressor becomes more compact, so that the compressor remains handy and portable despite the large storage volume.
the necessary number of components can be reduced by the integration of the compressed air storage tank in the crankcase, which again reduces the assembly costs for the compressor.
the storage of the drive shaft in a one-piece crankcase section also eliminates the complex adjustment of the individual bearings to each other.
necessary components such as pressure sensor, pressure gauge, safety valve, check valve, drain valve are connected cost-effectively and without additional piping to the integrated compressed air storage tank.
the compressor may further comprise an engine mount, which receives and supports the engine, and which is connected to the crankcase to form the end wall between the crankcase and the engine.
the compressor may further comprise at least one first bearing, which supports the drive shaft, and which is arranged within the hollow body formed by the inner chamber wall.
the compressor may comprise at least a second bearing which supports the drive shaft.
the second bearing can be arranged according to an embodiment variant within the hollow body formed by the inner chamber wall between the engine and the first bearing.
the second bearing may be arranged outside the hollow body formed by the inner chamber wall in the engine.
the first and / or second bearing may be, for example, grease-lubricated rolling bearings.
the crankcase may be formed monolithic with the inner chamber wall, the outer chamber wall and the partition wall.
the monolithic crankcase can be designed as a light metal casting.
the compressor may further comprise at least one strut, which extends axially to the drive shaft between the inner chamber wall and the outer chamber wall, and which divides the compressed air storage tank into at least two partial storage areas.
the at least two partial storage areas can be fluidically interconnected by compressed air lines, valves, and / or bottlenecks.
the compressor may further comprise at least one longitudinal rib, which is formed integrally with the crankcase on the outside of the compressed air storage tank.
the compressor may further comprise an engine mount which receives and supports the engine, the crankcase being spaced from the engine mount about the engine, and wherein the compressed air reservoir is at least partially around the engine between crankcase and engine mount extends around.
the compressed air storage tank can surround the drive shaft in an angular range of 360 °.
the ratio of the distance of the axis of rotation of the drive shaft to the point of the inner wall of the compressed air storage tank furthest from the drive shaft to the distance of the axis of rotation of the drive shaft to top dead center of a piston of the compressed air generating device can be between 0.2 and 1 ,
the ratio of the distance of the axis of rotation of the drive shaft to the point of the inner wall of the compressed air storage tank furthest from the drive shaft to the maximum axial extent of the compressed air storage tank 25 can be between 0.3 and 2.5.
the compressed air generating device may have at least one compressor chamber, and the volume ratio between the volume of the compressed air storage tank and the sum of the geometric stroke volumes of the compressor chambers of the compressed air generating device may be between 5 and 25.
Fig. 1 shows a schematic representation of a compressor 100 in sectional view.
the compressor 100 generally includes a motor 40 that may be supported in a motor mount 41.
the motor 40 may be, for example, an electric motor with speed control. It may be possible to use synchronous motors such as brushless DC motors or asynchronous motors.
the engine 40 drives a drive shaft 24 that extends away from the engine 40 in a crankcase 20. In this case, the drive shaft 24 may be arranged substantially concentric with the cross section of the crankcase 20 in the middle.
the drive shaft 24 serves to drive a crank mechanism 6 which moves a piston 4 up and down in a cylinder 5, ie the crank mechanism 6 translates the rotational movement of the drive shaft 24 into a linear movement along the extension direction of the piston 4 in the cylinder 5 the crank mechanism 6 have a counterweight, a crank arm, a connecting rod, a connecting rod bearing and / or a piston pin.
a compressor chamber 11 is formed at the top of the cylinder housing, in which according to the main function of the compressor 100 air can be compressed. Subsequently, a fan 45 can be arranged on the crank mechanism 6.
a core component of the crankcase 20 is the compressed air storage tank 25, the in Fig. 1 is formed as an integral component of the crankcase 20.
the crankcase 20 an inner chamber wall 26a, which may be formed, for example, cylindrical with a circular or polygonal cross-section, and which receives the motor-related part of the drive shaft 24 and rotatably supports.
the bearing 28b is arranged in a first bearing seat.
the bearing 28b in the first bearing seat can support a motor remote part of the drive shaft 24 between the engine 40 and the crank mechanism 6, ie the bearing 28b supports the crank mechanism 6 in a flying manner.
another bearing 28a may be formed in a second bearing seat within the chamber wall 26a, which may support a proximal portion of the drive shaft 24 between the engine 40 and the crank mechanism 6, i. the bearing 28a supports the engine 40 on the fly.
the bearing seats of the bearings 28a and 28b can be better aligned with each other. This allows improved concentricity of the bearing seats to each other. It is possible to work both bearing seats of the bearings 28a and 28b in the crankcase 20 from one side, in particular when the radial extent of the bearing 28a is less than that of the bearing 28b.
the compressed air storage tank 25 is in Fig. 2 an exemplary cross section of the compressor 100 along the cross-sectional line AA in Fig. 1 shown.
the arrangement of the compressed air storage tank is substantially annular around the drive shaft 24.
the compressed air storage tank 25 include a minimum angle of 200 °, preferably at least 240 ° about the drive shaft 24.
the crankcase 20 is the crankcase 20 and thus the compressed air storage tank 25 in principle shown as a hollow cylinder.
the compressed air storage tank 25 is thereby limited by the inner chamber wall 26a on the one hand and an outer chamber wall 26b on the other hand in the radial direction with respect to the axis of rotation of the drive shaft 24.
the outer chamber wall 26b constitutes an outer wall of the crankcase 20 which completely receives the inner chamber wall 26a in its interior.
the topology of the exterior Chamber wall 26b and the inner chamber wall 26a formed housing substantially equal to two nested cylinders, such as circular cylinders, prismatic cylinders or cylinders with polygonal cross-sectional area.
the top surfaces of the cylinder jacket surfaces formed between the outer chamber wall 26b and the inner chamber wall 26a may then be closed by one or more partition walls 34 on the other side and one or more end walls 23 on the other side to form the volume of the compressed air storage tank 25.
the dividing wall 34 or the dividing walls 34 in this case have a main extension direction, which runs essentially perpendicular to the axial direction of the drive shaft 24.
the end wall 23 has a main extension direction, which is substantially perpendicular to the axial direction of the drive shaft 24, and spaced from the partition 34 and the partitions 34 by a length substantially corresponding to the longitudinal extent of the compressed air storage tank 25.
the compressed air storage tank 25 In the lateral direction of the compressed air storage tank 25 may be interrupted by one or more struts 33.
These partial storage volumes can be interconnected via compressed air lines or other connection lines such as bottlenecks.
compressed air cooler and / or valves can be arranged.
three struts 33 are shown, which divide the fully circulating compressed air storage tank 25 into three equal partial storage volumes, which cover 120 ° of the crankcase 20.
the braces 33 may be integrally formed with the crankcase 20, for example in a common metal casting.
Fig. 3 shows a detailed illustration of the compressor 100 Fig. 1 in longitudinal section.
the compressor 100 is in the example of Fig. 3 shown as dry-compressing, variable in the speed piston compressor 100, which operates on the principle of Hubkolbenverdichtung.
a dry compressing a compressor use oil-lubricated compressor.
the compression can, as in Fig. 3 as an example, in one stage - but it may also be possible to carry out the compaction in several stages.
the compressor according to Fig. 3 has in a right-side in the figure compressor section 1, a cylinder 5, in which a piston 4 is arranged for compressing air from the environment.
a piston 4 is arranged for compressing air from the environment.
air from the environment can be sucked into the compression space 11 via an inlet opening 3 with an inlet valve. This takes place during a downward movement of the piston 4.
the linear working movement for the piston 5 is generated via a crank mechanism 6, which is connected via a drive shaft 24 to the rotor 43 of the motor 40.
the drive shaft 24 can be mounted rotatably with respect to the crankcase 20 via two bearings 28a and 28b, for example, permanently lubricated roller bearings with fixed loose bearings.
the crankcase 20 has a crank drive section 21, which at least partially surrounds the crank drive 6, and a storage section 22, which adjoins the crank drive section 21 and is arranged axially between it and the motor 40.
the partition wall 34 separates the compressed air storage tank 25 in the interior of the crankcase 20 of the crank drive section 21, that is, the crank mechanism 6 itself is not in the air storage volume of the compressed air storage tank 25.
the storage section 22 is thus formed disjoint with the crank section 21.
the cylinder 5 and the piston 4 are not disposed within the storage portion 22, that is, that the volume of the compressed air storage tank does not include the cylinder 5 and the piston 4.
the storage section 22 comprises an inner chamber wall 26a, which is hollow body or tubular, is arranged around the drive shaft 24 and accommodates the area of the drive shaft 24 leading through the storage section 22 and at least one of the two bearings 28a and 28b.
the inner chamber wall 26a may have recesses for one or more bearing seats of the bearings 28a and 28b. In addition, more than two bearings 28a and 28b may be provided.
the storage portion 22 includes an outer chamber wall 26b which may be concentrically disposed about and spaced from the inner chamber wall 26a.
Inner chamber wall 26a and outer chamber wall 26b are preferably integral with crankcase 20, i. formed as a one-piece portion of the crankcase 20.
the inner chamber wall 26a and the outer chamber wall 26b define, together with one or more partitions 34 whose extension plane is substantially perpendicular to the axis of rotation of the drive shaft 24, a compressed air storage tank 25 of the compressor 100.
the compressed air storage tank 25 is concentric with the drive shaft 24 at least partially annular around the inner chamber wall 26a arranged. In other words, the compressed air storage tank 25 encloses the drive shaft 24 so that at least in a partial angle range.
Fig. 3 is the compressed air storage tank 25 completely, that is arranged in an angular range of 360 ° to the drive shaft 24 around.
the compressed air storage tank 25 defines over the corresponding dimensions of the chamber walls 26a and 26b and the axial distance L3 of the partition walls 34 to the end wall 23 of the crankcase 20 a control volume, which serves for receiving and intermediate storage of compressed air generated by the piston compressor.
the motor mount 41 can take over the torque support between the rotor and the stator of the motor 40.
the engine mount 41 may be a component that completely or partially surrounds the engine 40 and may include closed boundary walls with struts, pillars, or the like. In this case, the motor carrier 41 can also act as a completely closed motor housing.
the motor mount 41 can also form the end wall 23, which in the example of Fig. 3 between the motor 40 and memory section 22 is arranged. However, it can also be provided to arrange the end wall 23 on the outside of the motor 40, so that the motor 40 at least partially through the
Storage portion 22 is included, that is, that the volume of the compressed air storage tank 25 extends in the axial direction of the drive shaft 24 at least partially completely or in a partial angle range around the motor 40 around.
the intake air is compressed in the compression chamber 11 in a compressor operating stroke during the upward movement of the piston 4 and discharged via the outlet port 7 and an outlet valve disposed therein.
the compressed air which is expelled via the outlet opening 7 can be discharged into a compressed air line 8, which may comprise a region with a cooling line 9 for purposes of cooling.
a compressed air line 9 Via the cooling line 9, the compressed air passes through the check valve 10 in a compressed air storage tank 25 of the compressor 100th
the seal with respect to the environment may suitably be effected via seals 29 and 30, for example O-rings.
Both the crankcase 20 and the engine mount 41 may be reinforced by ribs 32. These ribs 32, which can be mounted in a similar form on the outside of the crankcase 20 and / or the engine mount 41, contribute to better heat dissipation from the compressed air. In addition, it is possible to thereby optimize the mechanical stability of the compressor 100.
a compressed-air delivery line for example a compressed-air hose for a compressed-air-operated tool, can be connected, through which the compressed air can be removed from the compressed air storage container 25 as required.
a compressor controller 60 may retrieve the pressure of the compressed air measured by a pressure sensor 27 disposed on the compressed air storage tank 25 via a control line 61. If the measured actual pressure in the compressed air storage tank 25 deviate from the setpoint pressure stored in the compressor control 60, a setpoint speed signal for the motor 40 can be determined from the control deviation, which the compressor control 60 as a control signal via a control line 62 to a motor control, for example the frequency converter 70 of an electric motor 40, are output. The frequency converter 70 regulates the speed of the motor 40 as a function of the transmitted drive signal.
the motor 40 is an electronically commutated synchronous external rotor motor, in which the frequency converter 70 is mounted directly to the stator 44.
the stator 44 carries the stator winding 46 and may be connected to the motor support 41 by screws, for example.
the torque required for the compression of the compressor 100 is generated in a known manner in cooperation with the permanent magnet 48 in the rotor 43 of the motor 40.
Fig. 4 shows a longitudinal section through a compact variable speed piston compressor 100 with alternative engine design. It differs from the compressor 100 in Fig. 1 essentially in that the motor 40 is an internal rotor motor with external frequency converter.
Fig. 5 is a more detailed illustration of the compressor of the Fig. 4 shown.
the motor 40 has an external frequency converter 70 which is connected to the motor 40 via a motor connecting cable 47.
a lid may be provided as an end wall 23.
the cover 23 may on the one hand fix the motor 40 to the engine mount 41, which can then take over a housing function for the motor 40.
the cover 23 can fluidically close the compressed air storage tank 25 located in the crankcase 20.
the maximum radial extent L2 (distance of the axis of rotation of the drive shaft 24 to the point of the inner wall of the compressed air storage tank 25 which is at a maximum distance from the drive shaft 24) may be at a specific ratio to the compressor length L1 (distance between the axis of rotation of the drive shaft 24 and the top dead center of the piston) stand.
the extent L2 may be less than or equal to the compressor length L1.
a ratio of L2 / L1 ⁇ 2/3 is advantageous.
the ratio L2 / L1 can be between 0.2 and 1, preferably between 0.4 and 0.66.
the extent L2 can be less than 150 mm, for example, to ensure the compactness and thus the hand-carrying capacity of the compressor 100.
the maximum radial extent L2 may be in a certain ratio to the maximum axial extent L3 of the compressed air storage tank 25. If the compressed air storage tank 25 is arranged between the crank mechanism 6 and the motor 40, the ratio L2 / L3 can be between 0.3 and 2.5, preferably between 0.5 and 1.33.
volume ratio between the volume V R of the compressed air storage tank 25 and the geometric stroke volume V H of the compressor chamber 11 can also be defined in order to damp the compressed air pulsations to be able to eliminate optimally.
the ratio V R / V H can be between 5 and 25.
crankcase 20 together with all chamber walls 26a, 26b and end walls 23 and partitions 34 can in the Fig. 1 to 5 be formed completely integrally, for example, by a lost mold casting method or a rapid prototyping method such as selective laser melting, 3D printing, additive layer manufacturing, electron beam melting, laser deposition welding or similar methods.
a lost mold casting method or a rapid prototyping method such as selective laser melting, 3D printing, additive layer manufacturing, electron beam melting, laser deposition welding or similar methods.
the crankcase 20 and its relevant components such as walls, partitions and end walls can be produced for example in a die-casting process, for example of a light metal such as aluminum or magnesium.
Fig. 6 . 7 and 8 show schematic representations of other variants of a compressor 100.
the compressors 100 of Fig. 6 and 7 differ from the compressors 100 of the Fig. 1 and 4 essentially in that the second bearing 28a is accommodated in the motor 40 - in Fig. 6 on the crankcase side of the engine 40, in Fig. 7 on the crankcase side of the engine 40.
the compressor 100 of the Fig. 8 has a crankcase 20, which together with the motor mount 41 forms a drive shaft axially expanded compressed air storage tank 25.
the compressed air storage tank 25 extends around the engine 40 inside the crankcase 20, which is spaced from the engine mount 41 accordingly.
the ratio L2 / L1 of maximum radial extent L2 to maximum axial extent L1 of the Compressed air storage tank 25 between 0.12 and 1, preferably between 0.2 and 0.5.
the compressed-air storage tank 25 can surround the motor 40 in a partial angle range of less than 360 ° or completely, that is to say in a circumference of 360 °. It may also be possible for the compressed air storage tank 25 to completely surround the motor 40 with respect to the angular area around the drive shaft 24, but only partially surround the motor 40 in the axial direction of the motor axis of rotation, that is, not completely up to the crank housing distal end of the motor carrier 40 ,
