Abstract
Description
Die Erfindung bezieht sich auf eine Antriebsanordnung nach der im Oberbegriff in Anspruch 1 näher definierten Art. The invention relates to a drive arrangement according to the closer defined in the preamble in
Gattungsgemäße Antriebsanordnungen werden insbesondere bei Einradtriebwerken wie beispielsweise Flurförderfahrzeuge, bestehend aus einem Antriebsmotor, welcher über ein Getriebe ein Fahrzeugrad antreibt, wobei das Fahrzeugrad um seine Lenkachse drehbar ausgeführt ist und die Gewichtskraft des Fahrzeugs über eine drehbare Lagerung vom ortsfesten Fahrzeugrahmen bzw. -gehäuse in das Fahrzeugrad einleitbar ist, verwendet. Ebenso besteht die Möglichkeit die Antriebsanordnung in Windkraftanlagen, dabei insbesondere als Hauptlager, Turmlager und Pitchlager, zu verwenden. Es besteht auch die Möglichkeit die Antriebsanordnung für Bearbeitungsmaschinen, insbesondere deren Tischlager oder bei Antriebsanordnungen in Militärfahrzeugen, insbesondere beim Turmlager zu verwenden. Generic drive arrangements are particularly in unicycle engines such as industrial trucks, consisting of a drive motor which drives a vehicle via a gear, the vehicle is rotatable about its steering axis and the weight of the vehicle via a rotatable mounting of stationary vehicle frame or housing in the Vehicle wheel is introduced, used. It is also possible to use the drive assembly in wind turbines, in particular as a main bearing, tower bearings and pitch bearings. There is also the possibility of using the drive arrangement for processing machines, in particular their table bearings or in drive arrangements in military vehicles, in particular in the tower bearing.
Die
Der vorliegenden Erfindung liegt die Aufgabe zugrunde eine Antriebsanordnung mit einer Lagerung zu schaffen, welche Axial- und Radialkräfte aufnimmt, dabei in axialer und radialer Richtung kompakt ausgeführt ist und kostengünstig herzustellen ist. The present invention has for its object to provide a drive assembly with a bearing which receives axial and radial forces, it is made compact in the axial and radial directions and is inexpensive to manufacture.
Die Aufgabe wird mit einer auch die kennzeichnenden Merkmale des Hauptanspruchs aufweisenden gattungsgemäßen Antriebsanordnung gelöst. The object is achieved with a characterizing features of the main claim having generic drive assembly.
Die Antriebsanordnung weist eine Lagerung zur drehbaren Lagerung eines ersten Bauteils in einem zweiten Bauteil auf, über welche axiale und radiale Kräfte übertragbar sind. Die Lagerung beinhaltet ein erstes Kegelrollenlager mit einem Innenring und einem Außenring und ein zweites Kegelrollenlager mit einem Innenring und einem Außenring, wobei der Außenring des zweiten Kegelrollenlagers einen kleineren Durchmesser aufweist als der Innenring des ersten Kegelrollenlagers und das zweite Kegelrollenlager zumindest teilweise innerhalb des ersten Kegelrollenlagers angeordnet ist. Zusätzlich sind die Rollen des ersten und des zweiten Kegelrollenlagers in die gleiche Richtung geneigt. The drive arrangement has a bearing for the rotatable mounting of a first component in a second component, via which axial and radial forces can be transmitted. The bearing includes a first tapered roller bearing having an inner ring and an outer ring and a second tapered roller bearing having an inner ring and an outer ring, wherein the outer ring of the second tapered roller bearing has a smaller diameter than the inner ring of the first tapered roller bearing and the second tapered roller bearing at least partially disposed within the first tapered roller bearing is. In addition, the rollers of the first and second tapered roller bearings are inclined in the same direction.
Es besteht die Möglichkeit die Lagerung anstatt der Kegelrollenlager auch mit Schrägkugellager auszuführen, wobei auch bei der Verwendung der Schrägkugellager bei beiden Lagern die Wirkrichtung die gleiche Richtung aufweisen muss. Bei der vorliegenden Erfindung beinhaltet die Definition Kegelrollenlager somit alle Arten von Wälzlagern, die axiale und radiale Kräfte übertragen können, wie z. B. Kegelrollenlager und Schrägkugellager. It is possible to carry out the storage instead of the tapered roller bearings with angular contact ball bearings, which also in the use of angular contact ball bearings must have the same direction in both camps the direction of action. In the present invention, the definition of tapered roller bearings thus includes all types of rolling bearings that can transmit axial and radial forces, such. B. tapered roller bearings and angular contact ball bearings.
Zwischen dem Innenring des ersten Kegelrollenlagers und dem Außenring des zweiten Kegelrollenlagers ist das erste oder das zweite Bauteil angeordnet, wobei dieses Bauteil zumindest aus einem Zylinder und zwei Kreisscheiben, welche jeweils an den Enden des Zylinders angeordnet sind, besteht. Das erste und das zweite Bauteil kann einstückig oder mehrstückig ausgeführt sein. Between the inner ring of the first tapered roller bearing and the outer ring of the second tapered roller bearing, the first or the second component is arranged, wherein this component consists of at least one cylinder and two circular discs, which are respectively arranged at the ends of the cylinder. The first and the second component may be made in one piece or in several pieces.
Bei der Definition Zylinder ist bei vorliegender Erfindung somit der radiale Lagersitz zu verstehen. Bei der Definition Kreisscheibe ist somit die axiale Lagerunterstützung zu verstehen. In the definition of cylinder is thus to be understood in the present invention, the radial bearing seat. In the definition circular disc is thus the axial bearing support to understand.
Eine Außenwand des Zylinders liegt am Innenring des ersten Kegelrollenlagers an und die Innenwand des Zylinders liegt am Außenring des zweiten Kegelrollenlagers an und eine Kreisscheibe liegt an einer Axialseite des Innenrings des ersten Kegelrollenlagers an und eine weitere Kreisscheibe liegt an einer Axialseite des Außenrings des zweiten Kegelrollenlagers an, wodurch Radial- und Axialkräfte vom ersten Bauteil in das zweite Bauteil übertragbar sind. An outer wall of the cylinder abuts against the inner race of the first tapered roller bearing and the inner wall of the cylinder abuts the outer race of the second tapered roller bearing and a circular disk abuts an axial side of the inner race of the first tapered roller bearing and another circular disk abuts an axial side of the outer race of the second tapered roller bearing , whereby radial and axial forces from the first component to the second component are transferable.
Indem das zweite Kegelrollenlager innerhalb des ersten Kegelrollenlagers angeordnet ist, zeichnet sich die Antriebsanordnung durch eine geringe Bauhöhe aus. Indem sich das erste Kegelrollenlager über den Zylinder und die beiden Kreisscheiben auf dem zweiten Kegelrollenlager abstützt, wird eine präzise steife Lagerung geschaffen. By the second tapered roller bearing is disposed within the first tapered roller bearing, the drive assembly is characterized by a low height. By supporting the first tapered roller bearing over the cylinder and the two circular discs on the second tapered roller bearing, a precisely rigid bearing is created.
