Description
Die Erfindung bezieht sich auf ein Wälzlager mit einem Lagerinnenring, einem Lageraußenring und mit als Rollen ausgeführten Wälzkörpern, die in einem mit Querstreben und Seitenringen versehenen Käfig geführt sind.The invention relates to a rolling bearing with a bearing inner ring, a bearing outer ring and rolling elements designed as rollers, which are guided in a cage provided with cross struts and side rings.
Ein derartiges mit als Rollen ausgebildeten Wälzkörpern ist aus der
Aufgabe der Erfindung ist es, Wälzkörper zur Verfügung zu stellen, bei denen die geschilderten Nachteile behoben sind. Es soll eine einfache kostengünstige Ausgestaltung zur Verfügung gestellt werden.The object of the invention is to provide rolling elements available in which the disadvantages described are eliminated. It should be made available a simple cost-effective design.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass die Wälzkörper Scheiben aufweisen, die nebeneinander auf einer Achse gelagert sind. Durch diese Ausgestaltung kann sich jede Scheibe entsprechend ihrer Reibung frei auf der Achse drehen, ohne dass die kompletten Wälzkörper beeinflusst werden. Die Scheiben können abwechselnd aus unterschiedlichen Werkstoffen hergestellt sein. Sie können beispielsweise als Stahlscheiben mit abwechselnd keramischen Scheiben oder nur aus Stahlscheiben oder aus Stahl-, Kunststoffscheiben oder Keramik-, und Kunststoffscheiben kombiniert werden. Dabei kann die Belastung und das Gewicht des Lagers mit berücksichtigt werden.According to the invention the object is achieved in that the rolling elements have discs which are mounted side by side on an axis. By this configuration, each disc can rotate freely on the axis according to their friction, without the entire rolling elements are affected. The discs can be made alternately of different materials. They can be combined, for example, as steel disks with alternating ceramic disks or only from steel disks or from steel, plastic disks or ceramic and plastic disks. The load and the weight of the bearing can be taken into account.
In vorteilhafter Weise ist die Achse hohl ausgeführt und an ihren Enden je mit einem Bördelrand versehen, die in Seitennuten der äußeren Scheiben angeordnet sind. Dadurch ergibt sich eine seitliche Abstützung zu den Seitenringen. Advantageously, the axis is made hollow and each provided at their ends with a bead, which are arranged in side grooves of the outer discs. This results in a lateral support to the side rings.
Die Achsen können auch seitliche Zapfen aufweisen oder mit einem durchgehenden Stift versehen sein, die in einen oder beiden Seitenringen eingreifen, sodass die Querstreben sehr schmal ausgebildet sein können oder ganz entfallen können. Zur Verbesserung der Schmierung können die Scheiben an ihren Innen- und/oder Außenrändern Abflachungen, Abrundungen oder auch Seitennuten aufweisen, von denen aus auch der Zwischenraum der Scheiben geschmiert werden kann.The axes may also have lateral pins or be provided with a continuous pin, which engage in one or both side rings, so that the cross braces can be made very narrow or can be completely eliminated. To improve lubrication, the discs may have at their inner and / or outer edges flats, rounding or side grooves, from which also the gap of the discs can be lubricated.
