Abstract
Vorgeschlagen ist ein Käfig (4) für ein Wälzlager, insbesondere für ein Tandem Schrägkugellager oder Kegelrollenlager, der zur Führung von Wälzkörpern (3) zwischen einem Innenlagerring (2) und einem Außenlagerring (1) angeordnet ist und zumindest an der von Öl beaufschlagten Seite einen Führungsring (5) aufweist, in dessen freier Fläche eine umlaufende Ausnehmung eingearbeitet ist, und wobei die Ausnehmung als teilkreisförmige Nut (6) ausgeführt ist.Proposed is a cage (4) for a rolling bearing, in particular for a tandem angular contact ball bearing or tapered roller bearing, which is arranged to guide rolling elements (3) between an inner bearing ring (2) and an outer bearing ring (1) and at least on the side acted upon by oil Guide ring (5), in the free surface of a circumferential recess is incorporated, and wherein the recess is designed as a part-circular groove (6).
Description
Die Erfindung bezieht sich auf einen Käfig für ein Wälzlager, insbesondere für ein Tandem Schrägkugellager oder Kegelrollenlager, der zur Führung von Wälzkörpern zwischen einem Innenlagerring und einem Außenlagerring angeordnet ist und zumindest an der von Öl beaufschlagten Seite einen Führungsring aufweist, in dessen freier Fläche eine umlaufende Ausnehmung eingearbeitet ist.The invention relates to a cage for a rolling bearing, in particular for a tandem angular contact ball bearing or tapered roller bearing, which is arranged to guide rolling elements between an inner bearing ring and an outer bearing ring and at least on the acted upon by oil side has a guide ring in the free area of a circumferential Recess is incorporated.
Ein derartiger Käfig ist aus der
Aufgabe der Erfindung ist es, einen Käfig für ein Wälzlager zur Verfügung zu stellen, bei dem die geschilderten Nachteile behoben sind. Es soll eine einfache kostengünstige Ausgestaltung und Anordnung des Führungsringes an einem Wälzlager zur Verfügung gestellt werden.The object of the invention is to provide a cage for a rolling bearing available, in which the described disadvantages are eliminated. It is intended to provide a simple cost-effective design and arrangement of the guide ring on a rolling bearing.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass die Ausnehmung als teilkreisförmige Nut ausgeführt ist. Die Nut ist dabei so ausgeführt, dass ihr Außenrand in Höhe des Innenrandes einer Anphasung oder Rundung am Lageraußenring angeordnet ist. Entsprechend ist die Nut weiter so ausgeführt, dass ihr Innenrand in Höhe des Außenrandes einer Anphasung oder Rundung am Lagerinnenring angeordnet ist. Dadurch ergeben sich glatte Übergänge vom Lagerinnenring zum Führungsring und weiter zum Lageraußenring, wobei die teilkreisförmige Form der Nut einen stetigen Übergang sicherstellt und nicht, wie bei Kerben, eine abrupte Umlenkung vorgesehen ist. Von Bedeutung ist dabei, dass die teilkreisförmige Nut im Wesentlichen die komplette Radialerstreckung des Führungsringes einnimmt. Weiterhin ist der dem Führungsring benachbarte Bereich des Lagerinnenringes konisch ausgeführt und die zugeordnete Mantelfläche des Führungsringes parallel zur Lagerdrehachse ausgebildet. Dadurch wird ein definierter Spalt erzeugt, der genügend Öl zu den Wälzkörpern führt und gleichzeitig die Menge begrenzt.According to the invention the object is achieved in that the recess is designed as a part-circular groove. The groove is designed so that its outer edge is arranged at the level of the inner edge of a chamfering or rounding on the bearing outer ring. Accordingly, the groove is further designed so that its inner edge is located at the level of the outer edge of a chamfering or rounding on the bearing inner ring. This results in smooth transitions from the bearing inner ring to the guide ring and further to the bearing outer ring, wherein the part-circular shape of the groove ensures a steady transition and not, as in notches, an abrupt deflection is provided. It is important that the part-circular groove occupies substantially the entire radial extent of the guide ring. Furthermore, the guide ring adjacent region of the bearing inner ring is made conical and formed the associated lateral surface of the guide ring parallel to the bearing axis of rotation. As a result, a defined gap is created, which leads sufficient oil to the rolling elements and at the same time limits the amount.
