Title
(DE) LAGERANORDNUNG SOWIE DARIN VORGESEHENES HALTERINGELEMENT

Abstract
(DE)
Die Erfindung bezieht sich auf eine Lageranordnung mit wenigstens einem Lagerring, der eine Laufbahn für daran abrollende Wälzkörper bereitstellt, einem Ansatzelement das auf einen Sitzabschnitt aufgesetzt ist, der an dem Lagerring gebildet ist und eine Umfangsnut aufweist, wobei in dieser Umfangsnut ein Halteringelement sitzt, das eine radial über den Sitzabschnitt hervorragende Schulter bildet, die das Ansatzelement auf dem Sitzabschnitt axial sichert. Das Halteringelement ist derart gestaltet, dass dieses in einer die Lagerachse enthaltenden Schnittebene einen Querschnitt aufweist dessen in Richtung der Lagerachse gemessene Breite kleiner ist als die ebenfalls in Richtung der Lagerachse gemessene Breite der Umfangsnut. Zudem ist das Halteringelement in seinem Verlauf in Umfangsrichtung axial alternierend, d.h. "wellig" gestaltet und das Ausmaß in welchem das Halteringelement in seinem Verlauf in Umfangsrichtung axial alterniert ist größer als der in Richtung der Lagerachse gemessene Axialabstand der gegeneinander axial abgestützten axialen Anlagezonen des Lagerringes und des Ansatzelementes.
(EN)
The invention relates to a bearing assembly comprising at least one bearing ring which provides a raceway for rolling bodies rolling thereon, a protruding element which rests on a seat section which is formed on the bearing ring and has a circumferential groove, wherein a retaining ring element sits in this circumferential groove, which forms a shoulder projecting radially beyond the seat section, which axially secures the protruding element on the seat section. The retaining ring element is designed in such a way that it has a cross-section in a cross-sectional plane containing the bearing axis, the width of which cross-section measured in the direction of the bearing axis is smaller than the width of the circumferential groove when also measured in the direction of the bearing axis. In addition, the retaining ring element is designed such that its course is axially alternating in the circumferential direction, i.e. wavy, and the extent to which the course of the retaining ring element is axially alternating in the circumferential direction is greater than the axial distance between the axial contact zones of the bearing ring and the protruding element, which axial contact zones are axially supporting one another, when measured in the direction of the bearing axis.

L'invention concerne un ensemble de palier comportant au moins une bague de palier qui forme un chemin de roulement pour des éléments roulants roulant sur celui-ci, un élément de raccordement qui est monté sur une partie d'assise qui est formée sur la bague de palier et qui présente une rainure périphérique, un élément formant bague de retenue étant placé dans cette rainure périphérique, qui forme un épaulement dépassant radialement de la partie d'assise, qui fixe axialement l'élément de raccordement sur la partie de siège. L'élément de la bague de retenue est conçu de telle sorte que, dans un plan en coupe contenant l'axe de palier, il présente une section transversale dont la largeur mesurée dans la direction de l'axe de palier est inférieure à la largeur de la rainure périphérique mesurée également dans la direction de l'axe de palier. En outre, l'élément de bague de retenue alterne axialement, c'est-à-dire "ondulé", dans sa direction circonférentielle et la mesure dans laquelle l'élément de bague de retenue alterne axialement dans sa direction circonférentielle est supérieure à la distance axiale mesurée dans la direction de l'axe du palier entre les zones de contact axial supportées axialement de la bague de palier et l'élément de raccordement.
