Abstract
(DE)
Die Erfindung betrifft ein Wälzlager (1), mit einem Innenlaufring, einem Außenlaufring, mehreren zwischen den Laufringen angeordneten und in einem Lager käfig (3) geführten Wälzkörpern (9), wobei der Lagerkäfig (3) zur Aufnahme der Wälzkörper (9) umfangsseitig gleich verteilt angeordnete Lagertaschen (8) auf weist, die axial und umfangsseitig weitgehend geschlossen sind und jeweils einen der Wälzkörper (9) enthalten. Zur Verbesserung der Betriebseigenschaften des Wälzlagers (1) weist der Lagerkäfig (3) an jeder der Lagertaschen (8) mindestens ein passives Stellelement (14) auf, durch das die Taschenluft (16, 17) des zugeordneten Wälzkörpers (9) durch eine temperaturabhängige Formänderung des Stellelementes (14) veränderbar ist.
(EN)
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).
(FR)
L'invention concerne un palier à roulement (1) comprenant une bague de roulement intérieure, une bague de roulement extérieure et plusieurs organes de roulement (9) disposés entre les bagues de roulement et guidés dans une cage de palier (3), cette cage de palier (3) présentant à intervalles réguliers sur sa périphérie des creux d'appui (8) destinés à recevoir les organes de roulement (9). Ces creux d'appui (8) sont sensiblement fermés axialement et sur la périphérie et ils contiennent chacun un des organes de roulement (9). Selon l'invention, pour améliorer les propriétés de fonctionnement de ce palier à roulement (1), la cage de palier (3) présente au niveau de chaque creux d'appui (8) au moins un élément de réglage (14) passif au moyen duquel le jeu (16, 17) entre le creux et l'organe de roulement (9) associé peut être modifié par déformation dudit élément de réglage (14) sous l'effet de la température.
