Title
(EN) ROLLING ELEMENT BEARING WITH NON-UNIFORM ROLLING ELEMENT SPACINGS
(FR) SUPPORT D'ELEMENTS ROULANTS PRESENTANT DES ECARTEMENTS IRREGULIERS
Abstract
(EN)
A rolling element bearing comprises an inner ring, an outer ring, a series of rolling elements which are in contact with the raceways of said rings, and a cage (1) providing spacings (5) between the rolling elements, a plurality of said spacings being non-uniform. At least two of the non-uniform spacings are mutually different magnitudes, in order to obtain a better behaviour with respect to vibration and sound generation.
(FR)
Support d'éléments roulants comprenant un anneau intérieur, un anneau extérieur, une série d'éléments roulants en contact avec les chemins de roulement desdits anneaux, et une cage (1) créant des écartements (5) entre ces éléments roulants, une pluralité desdits écartements présentant un aspect non uniforme. Au moins deux des écartements non uniformes possèdent des longueurs réciproquement différentes, ce qui permet d'obtenir un comportement amélioré en ce qui concerne les vibrations et le bruit.
