Description
Gebiet der ErfindungField of the invention
Die Erfindung betrifft eine Ritzelwellenlagerung, umfassend eine Ritzelwelle mit einem Ritzelkopf, welche Ritzelwelle über wenigstens ein kopfseitiges Schräglager und wenigstens ein im Bereich des anderen Wellenendes vorgesehenes Schräglager in einer Hülse gelagert ist, wobei wellenseitig eine oder mehrere der Bildung einer Wälzkörperlaufbahn oder einer Aufnahme eines Lagerrings dienende Schultern vorgesehen sind, und wobei die Ritzelwelle einen lösbaren Ritzelkopf trägt, der auf einen Wellensitz aufgesetzt ist.The invention relates to a pinion shaft bearing, comprising a pinion shaft with a pinion head, which pinion shaft is mounted on at least one head-side angular contact bearing and at least one provided in the region of the other shaft end angular contact bearing in a sleeve, wherein the shaft side, one or more of the formation of a rolling element raceway or a receptacle of a bearing ring serving shoulders are provided, and wherein the pinion shaft carries a releasable pinion head, which is placed on a shaft seat.
Hintergrund der ErfindungBackground of the invention
Ritzelwellenlagerungen kommen überall dort zum Einsatz, wo Drehbewegungen einer Welle respektive über eine Welle zu übertragende Drehmomente umgelenkt oder verzweigt werden sollen. Ein jedoch nicht beschränkendes Beispiel ist die Verzweigung einer Antriebswelle eines Kraftfahrzeugs beispielsweise im Bereich der Hinterachse, um die Hinterräder anzutreiben. Die Ritzelwellenlagerung kommt dort beispielsweise in einem Differential zum Einsatz.Pinion shaft bearings are used wherever rotary movements of a shaft or torques to be transmitted via a shaft are to be deflected or branched. However, a non-limiting example is the branching of a drive shaft of a motor vehicle, for example in the region of the rear axle, in order to drive the rear wheels. The pinion shaft bearing is used there for example in a differential.
Solche Ritzelwellenlagerungen sind entweder in Form von angestellten Kegelrollenlagern oder, worauf die Erfindung gerichtet ist, in Form von Schräglagern wie beispielsweise Schrägkugellagern in teilweise mehrreihiger Ausführung realisiert. Jede Ritzelwellenlagerung umfasst dabei eine äußere Hülse, in der die den Ritzelkopf tragende Ritzelwelle über die wenigstens zwei vorgesehenen Schräglager, von denen eines kopfseitig und eines im Bereich des anderen Wellenende vorgesehen ist, gelagert ist. Schräglager können dabei einen Innenring und einen Außenring aufweisen, wobei der jeweilige Innenring auf der Ritzelwelle aufsitzt, während der Außenring hülsenseitig festgelegt ist. Denkbar ist es aber auch, wellenseitig unmittelbar die Wälzkörperlaufbahnen auszubilden.Such pinion shaft bearings are realized either in the form of employed tapered roller bearings or, where the invention is directed, in the form of angular bearings such as angular contact ball bearings in some multi-row design. Each pinion shaft bearing comprises an outer sleeve, in which the pinion shaft supporting the pinion shaft is mounted on the at least two provided angular contact bearings, one of which is provided on the head side and one in the region of the other shaft end. Angular bearing can have an inner ring and an outer ring, wherein the respective inner ring is seated on the pinion shaft, while the outer ring is fixed on the sleeve side. It is also conceivable, however, to form the rolling body raceways directly on the shaft side.
Daneben ist es bekannt, den Ritzelkopf lösbar an der Ritzelwelle anzuordnen, was sich aus Montagegründen als zweckmäßig erwiesen hat. Ein Beispiel für eine solche Ritzelwellenlagerung ist in

Zusammenfassung der ErfindungSummary of the invention
Der Erfindung liegt damit das Problem zugrunde, eine demgegenüber in der Herstellung vereinfachte Ritzelwellenlagerung anzugeben.The invention is therefore based on the problem of specifying a simplified compared to the manufacture pinion shaft bearing.
Die Aufgabe ist mit einer Ritzelwellenlagerung nach den Merkmalen des Anspruchs 1 gelöst.The object is achieved with a pinion shaft bearing according to the features of
Demnach ist an der Ritzelwelle eine Sacklochbohrung vorgesehen. Dabei umschließt der Ritzelkopf den Wellensitz in axialer Erstreckung auf dessen gesamten Umfangslänge. Außerdem deckt der Ritzelkopf die axiale Stirnfläche der Ritzelwelle und die Öffnung der Sacklochbohrung dort vollständig ab. Darüber hinaus ist vorgesehen, dass der Durchmesser des Wellensitzes dem Durchmesser der höchsten zylindrischen Schulter des Schräglagers entspricht.Accordingly, a blind hole is provided on the pinion shaft. In this case, the pinion head surrounds the shaft seat in the axial extent over its entire circumferential length. In addition, the pinion head covers the axial end face of the pinion shaft and the opening of the blind hole completely there. In addition, it is provided that the diameter of the shaft seat corresponds to the diameter of the highest cylindrical shoulder of the angular bearing.
Der Wellensitz wird nicht separat als zylindrischer Ansatz herausgearbeitet, vielmehr entspricht er im Durchmesser der bevorzugt unmittelbar an ihn anschließenden Schulter, über die ein Schräglager gelagert respektive abgestützt ist. An diesem Wellensitz können sodann entsprechende Verzahnungsabschnitte etc. ausgearbeitet werden, was wesentlich einfacher ist, zumal dieser Abschnitt nicht axial über die Schulter begrenzt ist, wie dies aber im Stand der Technik der Fall ist. Darüber hinaus liegt die Verzahnung auf einem größeren Umfang, was für die Kraftübertragung zweckmäßig ist.The shaft seat is not worked out separately as a cylindrical approach, but it corresponds in diameter to the preferably immediately adjoining him shoulder over which an angular contact bearing is mounted or supported. At this shaft seat corresponding toothed sections etc. can then be worked out, which is much easier, especially since this section is not axially limited over the shoulder, as is the case in the prior art. In addition, the gearing is on a larger scale, which is useful for power transmission.
Das kopfseitige Schräglager weist zweckmäßigerweise einen größeren Durchmesser auf als das oder die weiteren Schräglager, es ist über die direkt in den Wellensitz übergehende Schulter begrenzt.The head-side angular bearing expediently has a larger diameter than that or the other angular contact bearings, it is limited by the directly merging into the shaft seat shoulder.
