ROLLER BEARING WITH A WINDOW CAGE WITH POSITIONING ELEMENTS IN THE BEARING POCKETS FOR ALTERING THE POCKET PLAY BY MEANS OF TEMPERATURE-DEPENDENT CHANGE IN SHAPE OF THE POSITIONING ELEMENTS FOR EXAMPLE BY MEANS OF A SHAPE MEMORY ALLOY

摘要

The invention relates to a roller bearing (1), with an inner running ring, an outer running ring, several roller bodies (9), arranged between the running rings and guided in a bearing cage (3), whereby the bearing cage (3) comprises circumferential evenly distributed bearing pockets (8) which are essentially axially and circumferentially enclosed, and each of which contains a roller body (9). According to the invention, the operational characteristics of the roller bearing (1) may be improved whereby on each bearing pocket (8) the bearing cage (3) comprises at least one passive positioning element (14) by means of which the pocket play (16, 17) of the corresponding roller body (9) may be altered due to a temperature-dependent shape change of the positioning element (14).
