Abstract
Description
Gebiet der ErfindungField of the invention
Die Erfindung betrifft ein Schrägrollenlager mit einem Außenring und einem Innenring, zwischen denen in einem Käfig befindliche Wälzkörper abrollbar befindlich sind.The invention relates to a tapered roller bearing with an outer ring and an inner ring, between which located in a cage rolling elements are located unrollable.
Solche Lager sind bspw. aus der
Üblicherweise werden solche Schrägrollenlager auch im Automobilbereich verbaut, insbesondere im Bereich von Ritzelwellen wegen hohen Lasten.Usually, such tapered roller bearings are also installed in the automotive sector, especially in the field of pinion shafts because of high loads.
Der Außenring ist in einem Gehäuse befindlich, bspw. in einem Presssitz. Während der Montage der Ritzelwelle, auf der der Innenring des Schrägrollenlagers befindlich ist, muss die Ritzelwelle innerhalb des Außenrings hindurchgeführt werden. Die radiale Erstreckung des Außenrings in Richtung der Rotationsachse ist bei geringem Bauraum begrenzt.The outer ring is located in a housing, for example. In a press fit. During assembly of the pinion shaft, on which the inner race of the tapered roller bearing is located, the pinion shaft must be guided inside the outer ring. The radial extent of the outer ring in the direction of the axis of rotation is limited in a small space.
Die konstruktive Gestaltung der Getriebestufe wird dadurch eingeschränkt, da der Außenring wegen des geringen radialen Bauraums dünnwandig ausgeführt werden muss.The design of the gear stage is limited because the outer ring must be made thin-walled because of the small radial space.
Der dünnwandige Außenring vermindert die Leistungsfähigkeit des Lagers und ist bruchgefährdet. Der Druckwinkel kann nicht optimal gestaltet werden, wegen des geringen Querschnitts.The thin-walled outer ring reduces the performance of the bearing and is prone to breakage. The pressure angle can not be optimally designed because of the small cross section.
Es ist die Aufgabe der vorliegenden Erfindung diese Nachteile zu beseitigen.It is the object of the present invention to eliminate these disadvantages.
Offenbarung der ErfindungDisclosure of the invention
Dies wird dadurch gelöst, dass der Käfig zumindest einen Teil des Außenrings hintergreift.This is achieved in that the cage engages behind at least a part of the outer ring.
Auf diese Weise wird die Montage vereinfacht, da das Schrägrollenlager auch im komplett vormontierten Zustand im Gehäuse und auf der Ritzelwelle montierbar ist. Auch hält das Schrägrollenlager besser zusammen. Aufgrund eines vormontierten Schrägrollenlagers, das dann in diesem vormontierten Zustand auf der Ritzelwelle und dem Gehäuse verbaubar ist, kann der Außenring auch wieder dicker ausgestaltet werden, wodurch der Druckwinkel optimiert werden kann.In this way, the assembly is simplified because the tapered roller bearing can be mounted in the fully pre-assembled state in the housing and on the pinion shaft. Also, the tapered roller bearing holds together better. Due to a preassembled tapered roller bearing, which is then built in this preassembled state on the pinion shaft and the housing, the outer ring can also be made thicker again, whereby the pressure angle can be optimized.
Vorteilhafte Ausführungsformen sind in den Unteransprüchen beansprucht und werden nachfolgend näher erläutert.Advantageous embodiments are claimed in the subclaims and are explained in more detail below.
So ist es von Vorteil, wenn der Außenring eine Außenseite aufweist, die von einer mit den Wälzkörpern in Kontakt bringbaren Lauffläche des Außenrings beabstandet ist, wobei der Käfig zumindest einen Abschnitt der Außenseite des Außenrings umgreift. Auf diese Weise kann eine axiale Sicherung der Wälzkörper mittels des Käfigs relativ zum Außenring und dem Innenring erreicht werden.Thus, it is advantageous if the outer ring has an outer side which is spaced from a contact surface of the outer ring that can be brought into contact with the rolling bodies, wherein the cage surrounds at least a portion of the outer side of the outer ring. In this way, an axial securing of the rolling elements by means of the cage relative to the outer ring and the inner ring can be achieved.
Wenn der Käfig mindestens einen Hinterschnittbereich aufweist, der sich in radialer Richtung entlang einer Fläche der Außenseite erstreckt, so wird ein Auseinanderfallen des vormontierten Schrägrollenlagers wirkungsvoll verhindert.When the cage has at least one undercut portion extending radially along a surface of the outer side, disassembly of the pre-mounted tapered roller bearing is effectively prevented.
Es ist ferner von Vorteil, wenn der Hinterschnittbereich als Schnappnase, die auch als Haltenase bezeichnet werden kann, ausgebildet ist. Die Schnappnase ist dann Teil eines Schnappkäfigs und erleichtert die Montage.It is also advantageous if the undercut region is designed as a snap-in nose, which can also be referred to as a retaining nose. The snap nose is then part of a snap cage and facilitates the assembly.
Um ein Auseinanderfallen des vormontierten Schrägrollenlagers ferner zu verhindern, ist es von Vorteil, wenn der Innenring zwei sich in radialer Richtung erstreckende Borde aufweist, die in axialer Richtung gesehen beiderseits der Wälzkörper vorhanden sind.In order to prevent falling apart of the pre-mounted tapered roller bearing further, it is advantageous if the inner ring has two extending in the radial direction shelves, which are seen in the axial direction on both sides of the rolling elements available.
Auch ist es von Vorteil, wenn das Schrägrollenlager als Kegelrollenlager oder Schrägrollenlager mit zylindrischen Wälzkörpern ausgebildet ist.It is also advantageous if the tapered roller bearing is designed as a tapered roller bearing or tapered roller bearing with cylindrical rolling elements.
Varianten sind auch dadurch gekennzeichnet, dass die Wälzkörper kegelig oder zylindrisch ausgebildet sind und/oder in dem Käfig schleifend angeordnet sind.Variants are also characterized in that the rolling elements are conical or cylindrical and / or are arranged in the cage dragging.
Als besonders einfach montierbar hat sich ein Ausführungsbeispiel herausgestellt, bei dem die Schnappnase eine federelastische Beschaffenheit aufweist. Ein Abbrechen der Schnappnase wird in einer solchen Ausführungsform verhindert. Auch ist in einer Variante die Verwendung einer Vielzahl von Schnappnasen von Vorteil, insbesondere die Verwendung je einer Schnappnase pro Wälzkörper.As an especially easy to install, an embodiment has been found in which the snap nose has a resilient texture. Canceling the snap-action nose is prevented in such an embodiment. Also, in one variant, the use of a plurality of snap lugs of advantage, in particular the use of one snap-action nose per rolling element.
Ferner ist es von Vorteil, wenn der Außenring und/oder der Innenring und/oder die Wälzkörper aus gehärtetem Stahl gefertigt sind. Die Langlebigkeit eines solchen Schrägrollenlagers erhöht sich dadurch.Furthermore, it is advantageous if the outer ring and / or the inner ring and / or the rolling elements are made of hardened steel. The longevity of such a tapered roller bearing increases thereby.
Um auch den Käfig langlebig und trotzdem montagefreundlich auszugestalten ist es von Vorteil, wenn der Käfig aus Stahl gefertigt ist. Der Käfig kann sowohl aus metallischen wie auch aus nichtmetallischen Werkstoffen gefertigt sein.To make the cage durable and easy to assemble, it is an advantage if the cage is made of steel. The cage can be made of both metallic and non-metallic materials.
Die Schnappfunktion wird im elastischen Bereich des verwendeten Materials abgestimmt.The snap action is tuned in the elastic range of the material used.
Die Erfindung wird nachfolgend auch mit Hilfe einer Zeichnung erläutert. In dem einzigen dort dargestellten Ausführungsbeispiel ist ein erfindungsgemäßes Schrägrollenlager im Querschnitt mittels einer schematischen Darstellung visualisiert. Die Zeichnung dient nur dem Verständnis der Erfindung.The invention will be explained below with reference to a drawing. In the single embodiment shown there, an oblique roller bearing according to the invention is visualized in cross-section by means of a schematic representation. The drawing is only for understanding the invention.
