tes 3 et 4 correspondantes de-la bague intérieure 1. tes 3 and 4 corresponding to the inner ring 1.
Par leur surface intérieure, les pièces annulaires 12,13 prennent appui respectivement sur les éléments de roulement 7,8 tandis que leurs surfaces 5 extérieures sont en contact chacune avec un anneau en élastomère 14,15, le tout étant monté dans un boitier de tôle 16 et comprimé au montage de façon que les anneaux en élastomère 14,15 assurent d'une part la précontrainte du roulement et jouent d'autre part le 10 rôle d'amortisseurs de vibrations lors du fonctionnement du roulement. By their inner surface, the annular parts 12,13 respectively bear on the rolling elements 7,8 while their outer surfaces 5 are each in contact with an elastomer ring 14,15, the whole being mounted in a sheet metal case 16 and compressed during assembly so that the elastomer rings 14, 15 provide on the one hand the prestressing of the bearing and on the other hand play the role of vibration dampers during the operation of the bearing.
Les anneaux 14 et 15 sont disposés dans les zones du boitier extérieur 16 définies par la jonction des faces d'extrémité et de la surface latérale du 15 boitier, ce qui permet aux anneaux d'exercer sur les pièces annulaires 12,13, des efforts de précontrainte de direction moyenne normale à la surface des pièces annulaires. Les cages 9 et 10 de maintien des deux sé20 ries de rouleaux 7 et 8 présentent à leurs extrémités des chanfreins 17,18 qui permettent leur libre déplacement par rapport aux rebords 5 et 6 de la bague The rings 14 and 15 are arranged in the zones of the external housing 16 defined by the junction of the end faces and the lateral surface of the housing, which allows the rings to exert efforts on the annular parts 12, 13 preload in normal direction normal to the surface of the annular parts. The cages 9 and 10 for holding the two series of rollers 7 and 8 have at their ends chamfers 17, 18 which allow their free movement relative to the edges 5 and 6 of the ring.
