Problems solved by technology

But in fact in many rolling bearings due to the different thermal expansion of the bearing rings, rolling elements and bearing cage, the pocket clearance becomes smaller as the operating temperature rises, which results in greater bearing resistance and more severe wear and shorter service life

Embodiment Construction

[0028] A rolling bearing 1 designed as a ball bearing 2 has a riveted bearing cage 3, which is shown in FIG. 1 in a radial view A with a section 1a and in an axial view B with a section 1b, the bearing cage 3 consists of two symmetrical cage rings 4 connected by means of rivets 5 . The cage ring 4 has an axial arc-shaped arched pocket section 7 distributed uniformly over the circumference between every two connecting beams 6 . In the assembled state of the bearing cage 3, the pocket segments 7 of the mutually riveted cage rings 4 form closed bearing pockets 8 arranged evenly distributed on the circumference, each of which is fitted with a rolling bearing designed here as a ball 10. Body 9.

[0029] According to the invention, the pocket sections 7 which mainly function as the axial side walls 11 of the bearing pocket 8 each have an inner groove 13 oriented in the circumferential direction, that is to say in the direction of rotation 12 of the rolling bearing 1 , in the inner ...

Abstract

The invention relates to a roller bearing, with an inner running ring, an outer running ring, several roller bodies, arranged between the running rings and guided in a bearing cage, whereby the bearing cage comprises circumferential evenly distributed bearing pockets which are essentially axially and circumferentially enclosed, and each of which contains a roller body. According to the invention, the operational characteristics of the roller bearing may be improved whereby on each bearing pocket the bearing cage comprises at least one passive positioning element by means of which the pocket play of the corresponding roller body may be altered due to a temperature-dependent shape change of the positioning element.

Description

technical field [0001] The invention relates to a rolling bearing, which has a bearing inner ring, a bearing outer ring, a plurality of rolling bodies mounted between the bearing rings and guided in a bearing cage, wherein the bearing for receiving the rolling bodies is kept The frame has bearing pockets arranged evenly distributed in the circumferential direction, which are substantially closed axially and circumferentially and each contain a rolling body. Background technique [0002] In a simple embodiment, the rolling bearing consists of two bearing rings, namely an inner bearing ring and an outer bearing ring, between which the rolling bodies are mounted in a bearing cage. When the inner ring of the bearing rotates relative to the outer ring of the bearing, the rolling elements roll on the raceways of the bearing rings. In this case the movement of the rolling elements consists of a rolling movement and a sliding movement on the raceways of the bearing rings, wherein t...
