Title (EN) BEARING ASSEMBLY AND BEARING CAGE
(FR) ENSEMBLE PALIER ET CAGE DE PALIER
Abstract:
(EN) A bearing assembly (10 includes an outer ring (14) having an outer raceway (18) and an inner ring (22) having an inner raceway (26) and a flange (54) defining an outer diameter of the inner ring. A plurality of rolling elements (30) is retained between the outer and inner rings on the outer and inner raceways. A cage (34) has first and second side rings (38) interconnected by a plurality of bridges (42) to form a plurality of windows (46), each window receiving a respective rolling element (30) to maintain relative spacing between adjacent rolling elements. At least some of the bridges (42) include a projection (50) on a radially inner side such that the plurality of projections (50) together define an inner diameter of the cage (34), the inner diameter of the cage (34) being smaller than the outer diameter of the inner ring (22) to create interference and deformation of the cage (34) as the cage is installed over the flange (54) of the inner ring.
(FR) L'invention concerne un ensemble palier (10) comprenant une bague externe (14) ayant un chemin de roulement externe (18) et une bague interne (22) ayant un chemin de roulement interne (26) et une bride (54) définissant un diamètre externe de la bague interne. Une pluralité d'éléments de roulement (30) est retenue entre les bagues externe et interne sur les chemins de roulement externe et interne. Une cage (34) a des première et seconde bagues latérales (38) interconnectées par une pluralité de ponts (42) pour former une pluralité de fenêtres (46), chaque fenêtre recevant un élément de roulement respectif (30) pour maintenir un espacement relatif entre des éléments de roulement adjacents. Au moins certains des ponts (42) comprennent une saillie (50) sur un côté radialement interne de sorte que la pluralité de saillies (50) définissent ensemble un diamètre interne de la cage (34), le diamètre interne de la cage (34) étant inférieur au diamètre externe de la bague interne (22) pour créer une interférence et une déformation de la cage (34) lorsque la cage est installée sur la bride (54) de la bague interne.
