Description

Rollenmühle roller mill
Die Erfindung betrifft eine Rollenmühle mit einem drehbaren Mahlteller und wenigstens einer drehbar an einem Schwenkhebel gehalterten Mahlrolle, die mit dem Mahlteller in Abrolleingriff steht, wobei der Schwenkhebel um eineThe invention relates to a roller mill with a rotatable grinding plate and at least one rotatably mounted on a pivot lever Mahlerten Mahlrolle, which is in Abrolleingriff with the grinding table, wherein the pivot lever to a
Schwenkhebelachse schwenkbar gelagert ist.Swivel lever axis is pivotally mounted.
Bei Rollenmühlen in der industriellen Anwendung wird der Mahlteller angetrieben, welcher über das Mahlbett die Mahlrollen antreibt. Hierbei ist es im Allgemeinen erforderlich, ein Getriebe unterhalb des Mahltellers anzuordnen. Bei Mühlen mit großen Durchsatzleistungen muss man bei diesen Getrieben mit hohen Investitionskosten, langen Beschaffungszeiten und einer unzufriedenstellenden Verfügbarkeit rechnen.In roller mills in industrial applications, the grinding table is driven, which drives the grinding rollers via the grinding bed. In this case, it is generally necessary to arrange a gear below the grinding plate. For mills with high throughput rates, these gearboxes require high investment costs, long procurement times and unsatisfactory availability.
Man hat daher bereits vorgeschlagen, statt dem Mahlteller die Mahlrollen anzutreiben. Sind mehrere Mahlrollen vorgesehen, kann dadurch die Leistung zum Antreiben der Rollenmühle auf eine entsprechende Vielzahl von Antrieben verteilt werden. Auf diese Weise können kleinere und damit kostengünstigere Antriebe zum Einsatz kommen.It has therefore already been proposed to drive the grinding rollers instead of the grinding table. If several grinding rollers are provided, the power for driving the roller mill can be distributed to a corresponding plurality of drives. In this way, smaller and therefore less expensive drives can be used.
In der DE 38 01 728 C2 und der DE 36 02 932 Al wird der komplette Antrieb mit Motor und Getriebe auf dem die Mahlrolle halternden Schwenkhebel vorgesehen. Durch das nicht unerhebliche Gewicht des Antriebes werden aber bei dieser Ausführungsform erhöhte Anforderungen an die Lagerung des Schwenkhebels gestellt. Der Motor ist außerdem starken Vibrationen durch den Mahlprozess ausgesetzt.In DE 38 01 728 C2 and DE 36 02 932 Al the complete drive with motor and gear is provided on the grinding roller-holding pivot lever. Due to the not inconsiderable weight of the drive but increased demands are placed on the storage of the pivot lever in this embodiment. The engine is also exposed to strong vibrations during the grinding process.
In der DE 197 02 854 wird als alternative Ausführungsform ein feststehender Motor vorgeschlagen. Die Übertragung der Antriebsleistung auf das am Schwenkhebel befestigte Getriebe erfolgt über eine Kardangelenkwelle. Diese Gelenkwelle muss sowohl einen Winkelausgleich als auch einen axialen Längenausgleich gewährleisten. Da jedoch bis zur Mahlrolle sehr hohe Drehmomente übertragen werden müssen, muss der Antriebsstrang relativ aufwendig und teuer dimensioniert werden.In DE 197 02 854 a fixed motor is proposed as an alternative embodiment. The transmission of the drive power to the mounted on the pivot lever gearbox via a cardan shaft. This PTO shaft must have both an angle compensation and an axial length compensation guarantee. However, since very high torques must be transmitted to the grinding roller, the drive train must be relatively expensive and expensive.
Weiterhin ist aus der DE 295 563 ein Kollergang mit einem angetriebenen Teller und einem über einen Schwenkhebel gehalterten Läufer bekannt. Wobei der Antrieb des Läufers über einen feststehenden Motor und ein mit dem Schwenkhebel mitschwenkendes Getriebe erfolgt, wobei sich das mitschwenkende Getriebe bis in den Läufer erstreckt.Furthermore, from DE 295 563 a muller gangway with a driven plate and a content via a swivel lever held runners known. Wherein the drive of the rotor via a fixed motor and with the pivot lever mitschwenkendes gear, wherein the mitschwenkende transmission extends into the rotor.
Der Erfindung liegt daher die Aufgabe zugrunde den Antrieb der Rollenmühle kostengünstiger zu gestalten, erfindungsgemäß wird diese Aufgabe durch die Merkmale des Anspruches 1 gelöst.The invention is therefore the object of the drive of the roller mill to make cheaper, according to the invention this object is achieved by the features of claim 1.
Erfindungsgemäß wird diese Aufgabe durch die Merkmale des Anspruches 1 gelöst.According to the invention, this object is solved by the features of claim 1.
Die Erfindungsgemäße Rollenmühle besteht im Wesentlichen aus einem drehbaren Mahlteller wenigstens einer drehbar an einem Schwenkhebel gehalterten Mahlrolle, die mit dem Mahlteller in Abrolleingriff steht, wobei der Schwenkhebel um eine Schwenkhebelachse schwenkbar ist, sowie wenigstens einem mit der Mahlrolle inThe roller mill according to the invention consists essentially of a rotatable grinding plate at least one rotatably mounted on a pivot lever Mahlerten Mahlrolle, which is in Abrolleingriff with the grinding table, wherein the pivot lever is pivotable about a pivot lever axis, and at least one with the grinding roller in
Verbindung stehenden Antriebsstrang der einen ortsfesten Motor und ein ortsfestes Getriebe aufweist. Der Antriebsstrang weist weiterhin ein mit dem Schwenkhebel und/oder der Mahlrolle mitschwenkendes Getriebe auf.Compound powertrain having a fixed motor and a fixed gear. The drive train further comprises a mitschwenkendes with the pivot lever and / or the grinding roller gearbox.
Die beiden Getriebe werden vorzugsweise über eine winkelverstellbare und/oder axialverstellbare Welle miteinander verbunden.The two gears are preferably connected to one another via an angle-adjustable and / or axially adjustable shaft.
Durch die Verwendung von wenigstens zwei Getrieben können Übersetzungen erreicht werden, die eine Motorabtriebsdrehzahl von 1000 bis 3000 U/min ermöglichen. Durch schnell drehende Motoren können die für die Motoren notwendigen Investitionskosten gesenkt werden. Wird ein Teil der Übersetzungsarbeit durch ein ortsfestes Getriebe geleistet, an welches keine besonderen Anforderungen gestellt werden, ist ein standarisiertes und somit kostengünstiges Getriebe einsetzbar. Aufgrund des mitschwenkenden Getriebes, reduziert sich das Drehmoment in der winkel- und/oder radial - axialverstellbaren Welle um den Faktor der Übersetzung des mitschwenkenden Getriebes. Dadurch ist es möglich, den Bewegungsausgleich durch standardisierte Komponenten zu realisieren. So kann man diese Komponente beispielsweise mit einer Zahnkupplung auszugleichen, wodurch die Drehbewegung homokinetisch übertragen werden kann.Through the use of at least two transmissions, translations can be achieved which allow a motor output speed of 1000 to 3000 rpm. Fast-rotating motors can reduce the investment costs necessary for the motors. Will be part of Translation work done by a stationary gearbox, to which no special requirements are made, a standardized and thus inexpensive gear can be used. Due to the mitschwenkenden transmission, the torque in the angular and / or radially - axially adjustable shaft is reduced by the factor of the translation of mitschwenkenden transmission. This makes it possible to realize the motion compensation by standardized components. So you can compensate for this component, for example, with a toothed coupling, whereby the rotational movement can be transmitted homokinetic.
Gemäß einem bevorzugten Ausgestaltung der Erfindung handelt es sich bei dem mitschwenkenden Getriebe um ein Umlaufgetriebe, insbesondere ein leistungsverzweigtes Getriebe, welches beispielweise durch ein Planetengetriebe gebildet werden kann. Dieses mitschwenkende Getriebe kann auch in die Mahlrolle integriert oder an der Mahlrolle befestigt werden.According to a preferred embodiment of the invention, the mitschwenkenden gear is a planetary gear, in particular a power-split transmission, which can be formed for example by a planetary gear. This mitschwenkende transmission can also be integrated into the grinding roller or attached to the grinding roller.
Der Schwenkhebel ist in einem Lager gelagert, wobei das mitschwenkende Getriebe vor oder nach dem Lager im Arbeitsstrang geordnet werden kann.The pivot lever is mounted in a bearing, wherein the mitschwenkende transmission can be arranged before or after the camp in the work string.
Der Schwenkhebel kann als Hohlwelle ausgebildet werden, wobei ein Teil des Antriebsstranges in der Hohlwelle angeordnet ist.The pivot lever can be formed as a hollow shaft, wherein a part of the drive train is arranged in the hollow shaft.
Der Antriebsstrang kann weiterhin eine Kupplung aufweisen, welche in der Schwenkhebelachse bzw. deren Verlängerung angeordnet ist und die Schwenkbewegung des Schwenkhebels ausgleicht. Diese Kupplung kann beispielsweise als Zahnkupplung, insbesondere als Bogenzahnkupplung oder alsThe drive train may further comprise a coupling which is arranged in the pivot lever axis or its extension and compensates for the pivoting movement of the pivot lever. This coupling can be used, for example, as a toothed coupling, in particular as a curved tooth coupling or as

Weitere Vorteile und Ausgestaltungen der Erfindung werden im Folgenden anhand der Beschreibung und der Zeichnung näher erläutert.Further advantages and embodiments of the invention will be explained in more detail below with reference to the description and the drawing.

Die in Fig. 1 dargestellte Rollenmühle besteht im Wesentlichen aus einem drehbaren Mahlteller 1, wenigstens einer drehbar an einem Schwenkhebel 2 gehalterten Mahlrolle 3 sowie einem der Mahlrolle zugeordneten Antriebsstrang zum Antreiben der Mahlrolle mit einem feststehenden Motor 4. Der Schwenkhebel ist in einem Lager 5 um eine Schwenkhebelachse 6 schwenkbar gelagert. Der Schwenkhebel 2 ist weiterhin durch ein Mühlengehäuse 7 hindurchgeführt, wobei die Mahlrolle 3 an dem im Mühlengehäuse befindlichen Ende des Schwenkhebels gehaltert ist, während das andere Ende im Lager 5 außerhalb des Mühlengehäuses gelagert ist.The roller mill shown in Fig. 1 consists essentially of a rotatable grinding table 1, at least one rotatably mounted on a pivot lever 2 Mahlalter 3 and a grinding roller associated drive train for driving the grinding roller with a fixed motor 4. The pivot lever is in a bearing 5 to a pivot lever axis 6 pivotally mounted. The pivot lever 2 is further passed through a mill housing 7, wherein the grinding roller 3 is supported on the located in the mill housing end of the pivot lever, while the other end is mounted in the bearing 5 outside of the mill housing.
Weiterhin ist ein Anpresssystem 8, insbesondere ein hydro-pneumatischesFurthermore, a Anpresssystem 8, in particular a hydro-pneumatic
Federsystem, vorgesehen, um den Anpressdruck der Mahlrolle 3 einzustellen. Das Anpresssystem ist ebenfalls außerhalb des Mühlengehäuses 7 angeordnet und steht mit dem Schwenkhebel in Wirkkontakt.Spring system, provided to adjust the contact pressure of the grinding roller 3. The pressure system is also arranged outside of the mill housing 7 and is in operative contact with the pivot lever.
Die Mahlrolle 3 ist über eine Mahlrollenlagerung 9 drehbar am Schwenkhebel 2 gelagert. Der Schwenkhebel 2 ist weiterhin als Hohlwelle ausgebildet, sodass ein Teil des Antriebsstrangs in Form einer Antriebswelle 10 in der Hohlwelle angeordnet ist. Die Drehbewegung der Antriebswelle wird über eine Narbe 11 auf die Mahlrolle 3 übertragen. Mit dem anderen Ende steht die Antriebswelle 10 mit dem ortsfest angeordneten Motor 4 in Wirkverbindung, wobei wenigstens ein ortfestes Getriebe 14 und ein mit dem Schwenkhebel 2 mitschwenkendes Getriebe 15' zwischengeschaltet sind.The grinding roller 3 is rotatably supported by a Mahlrollenlagerung 9 on the pivot lever 2. The pivot lever 2 is further designed as a hollow shaft, so that a part of the drive train is arranged in the form of a drive shaft 10 in the hollow shaft. The rotational movement of the drive shaft is transmitted via a scar 11 on the grinding roller 3. At the other end, the drive shaft 10 is operatively connected to the stationary motor 4, wherein at least one stationary gear 14 and a mitschwenkendes with the pivot lever 2 gear 15 'are interposed.
Zwischen den beiden Getrieben 14 und 15' ist eine radial- und axial verstellbareBetween the two gears 14 and 15 'is a radially and axially adjustable
Welle 16' zur Übertragung der Drehbewegung und zum Ausgleich der Schwenkbewegung des Schwenkhebels 2 vorgesehen. Diese Welle 16' kann beispielsweise als Gelenkwelle ausgebildet werden. Durch die Aufteilung des Getriebes in ein ortsfestes Getriebe 14 und ein mit dem Schwenkhebel 2 mitschwenkendes Getriebe 15' kann die Welle 16' entsprechend kleiner dimensioniert werden, da das Hauptdrehmoment erst nach dem mitschwenkenden Getriebe 15' übertragen werden muss.Shaft 16 'provided for transmitting the rotational movement and to compensate for the pivotal movement of the pivot lever 2. This shaft 16 'may be formed, for example, as a propeller shaft. By dividing the transmission into a stationary gear 14 and a mitschwenkendes with the pivot lever 2 gear 15 ', the shaft 16' can be dimensioned correspondingly smaller, since the main torque must be transmitted only after the mitschwenkenden transmission 15 '.
Während das mitschwenkende Getriebe 15' im ersten Ausführungsbeispiel im Bereich des Lagers 5 des Schwenkhebels 2 angeordnet ist, wird es gemäß dem zweiten Ausführungsbeispiel in Fig. 2 in den Mahlraum, d.h. in das Mühlengehäuses 7 verlegt. Das mitschwenkende Getriebe 15 gemäß Fig. 2 ist am im Mühlengehäuse 7 befindlichen stirnseitigen Ende des Schwenkhebels 2 angeordnet und mit der Mahlrolle 3 verbunden.While the mitschwenkende transmission 15 'is arranged in the first embodiment in the region of the bearing 5 of the pivot lever 2, it is according to the second embodiment in Fig. 2 in the grinding chamber, i. laid in the mill housing 7. The mitschwenkende transmission 15 shown in FIG. 2 is located on the mill housing 7 located at the front end of the pivot lever 2 and connected to the grinding roller 3.
Gemäß einer alternativen Ausführungsform könnte das mitschwenkende Getriebe auch in der Mahlrolle integriert werden. Durch die Anordnung des mitschwenkenden Getriebes im Bereich der Mahlrolle werden die hohen Drehmomente genau da erzeugt, wo sie benötigt werden. Dadurch kann der bis zum mitschwenkenden Getriebe 15 führende Antriebsstrang entsprechend günstiger gefertigt und leicht beschafft werden. Durch die Reduzierung der Massen im Antriebsstrang reduziert sich außerdem das Massenträgheitsmoment. Dies wiederum erleichtert die Regelung und Steuerung des Antriebs. Durch den Mahlprozess sind die Antriebselemente Beschleunigungskräften ausgesetzt, sodass sich auch hier die Massenreduzierung positiv auf die Auslegung und Dauerfestigkeit der Lager auswirkt. Um die Schwenkbewegung des Schwenkhebels 2 im Antriebsstrang ausgleichen zu können, kann die Welle 16 im Bereich des Lagers 5 vorgesehen werden, sodass unter Umständen auch auf eine axiale Verstellbarkeit der Welle verzichtet werden kann und die Welle (16) nur eine Winke lverstellbarkeit sicherstellen muss.According to an alternative embodiment, the mitschwenkende transmission could also be integrated in the grinding roller. The arrangement of the mitschwenkenden transmission in the field of grinding roller, the high torques are generated exactly where they are needed. As a result, the leading to the mitschwenkenden transmission 15 powertrain can be made according cheaper and easily procured. Reducing the masses in the powertrain also reduces the mass moment of inertia. This in turn facilitates the control and regulation of the drive. Due to the grinding process, the drive elements are exposed to acceleration forces, so that here too the mass reduction has a positive effect on the design and fatigue strength of the bearings. In order to compensate for the pivotal movement of the pivot lever 2 in the drive train, the shaft 16 may be provided in the region of the bearing 5, so that under certain circumstances can be dispensed with an axial adjustability of the shaft and the shaft (16) lverstellbarkeit must ensure only one.
Bei der Anordnung gemäß Fig. 2 könnte man statt der winkel- und/oder radial- axialverstellbaren Welle 16 auch eine Kupplung vorsehen. Vorzugsweise wird die Kupplung zudem in der Schwenkhebeldrehachse 6 angeordnet. Dadurch dass die hohen Drehmomente erst beim mitschwenkenden Getriebe 15 erzeugt werden, kann die Kupplung 12 durch eine drehstarre Ausgleichskupplung, insbesondere eineIn the arrangement according to FIG. 2, one could also provide a coupling instead of the angularly and / or radially axially adjustable shaft 16. Preferably, the coupling is also arranged in the pivot lever pivot axis 6. Because the high torques are generated only when mitschwenkenden transmission 15, the clutch 12 by a torsionally rigid compensating coupling, in particular a
Bogenzahnkupplung, ausgebildet werden.Bogenzahnkupplung be trained.
Eine spezielle Ausgestaltung des zweiten Ausführungsbeispiels wird im Folgenden anhand von Fig. 3 näher erläutert.A specific embodiment of the second embodiment will be explained in more detail below with reference to FIG. 3.
Beim Ausführungsbeispiel gemäß Fig. 3 ist das mitschwenkende Getriebe 15 in Form eines Umlaufgetriebes ausgebildet. Es ist am Ende des Schwenkhebels 2 im Bereich der Mahlrolle 3 befestigt und als leistungsverzweigtes Getriebe, insbesondere als Planetengetriebe, ausgebildet.In the embodiment of FIG. 3, the mitschwenkende transmission 15 is in the form of a planetary gear. It is attached at the end of the pivoting lever 2 in the region of the grinding roller 3 and designed as a power-split transmission, in particular as a planetary gear.
Das Umlaufgetriebe weist, wie üblich, ein Sonnenrad 15a, mehrere Planetenräder 15b und einen Planetenträger 15c auf. Das Sonnenrad 15a kann kippbeweglich gelagert sein und wird über die Antriebswelle 10 angetrieben. Der Planetenträger ist drehfest mit der Mahlrolle 3 verbunden. Das Umlaufgetriebe ist zudem über einen vorzugsweise austauschbaren Verschleißschutz 15d geschützt. Weiterhin ist eine geeignete Momentenstütze vorzusehen, die beispielsweise durch seitliche Führungen des Anpresssystems 8 gebildet werden könnte.The planetary gear, as usual, a sun gear 15a, a plurality of planet gears 15b and a planet carrier 15c. The sun gear 15a can be tiltably mounted and is driven via the drive shaft 10. The planet carrier is rotatably connected to the grinding roller 3. The planetary gear is also protected by a preferably replaceable wear protection 15d. Furthermore, a suitable torque support should be provided, which could be formed, for example, by lateral guides of the Anpresssystems 8.
Nachdem ein Teil des Antriebsstranges ortsfest ausgebildet ist und ein anderer Teil, insbesondere die im Schwenkhebel 2 angeordnete Antriebswelle 10 mit demAfter a part of the drive train is formed stationary and another part, in particular arranged in the pivot lever 2 drive shaft 10 with the
Schwenkhebel 2 mitschwenkt, ist weiterhin eine Kupplung 12 vorgesehen, welche die Schwenkbewegung des Schwenkhebels ausgleicht. Vorzugsweise wird eine Kupplung 12 eingesetzt die in der Schwenkhebeldrehachse 6 angeordnet ist und die Drehbewegung homokinetisch überträgt.Swiveling pivot lever 2, a clutch 12 is further provided, which compensates for the pivoting movement of the pivoting lever. Preferably, a coupling 12 is used which is arranged in the pivot lever pivot axis 6 and transmits the rotational movement homokinetic.
Bei der Kupplung 12 handelt es sich um eine drehstarre Ausgleichskupplung, wobei insbesondere eine Bogenzahnkupplung vorgesehen werden kann.In the coupling 12 is a torsionally stiff compensating coupling, in particular a curved tooth coupling can be provided.
Gemäß einer weiteren Ausgestaltung der Erfindung verfügt die Mahlrollenlagerung 9, das Lager 5 und die Kupplung 12 über einen gemeinsamen Ölraum.According to a further embodiment of the invention, the grinding roller bearing 9, the bearing 5 and the coupling 12 has a common oil space.
Durch die Aufteilung des Getriebes in wenigstens ein ortsfestes Getriebe und wenigstens ein mitschwenkendes Getriebe lässt sich der Antriebsstrang zwischen den beiden Getrieben aufgrund des dort reduzierten Drehmomentes durch standardisierte Komponenten realisieren. Wird zudem das mitschwenkende Getriebe bis in den Mahlraum, d.h. im Bereich der Mahlrolle verlegt, kann ein momentenreduzierter und massenreduzierter Antriebsstrang vorgesehen werden. By dividing the transmission into at least one stationary transmission and at least one mitschwenkendes transmission, the drive train between the two transmissions due to the reduced torque there can be realized by standardized components. In addition, if the mitschwenkende transmission into the grinding chamber, i. laid in the area of the grinding roller, a torque-reduced and mass-reduced drive train can be provided.
