Abstract

L'invention concerne un dispositif de support dans lequel la surface intérieure d'un carter (112), dans lequel sont montés, de façon coaxiale, deux roulements à billes (111) soutenant une broche (un arbre) (S), est pourvue d'une partie à gradins (113) venant en butée contre la surface d'extrémité des bagues extérieures des roulements à billes (111). Les extrémités opposées du carter (112) présentent des parties d'assemblage (112a) destinées aux roulements à bille (111), et la surface intérieure du carter comprise entre les parties d'assemblage (112a) et la partie à gradins (113) est plus grande que le diamètre extérieur des roulements à billes (111). En outre, la longueur d'emmanchement à la presse de la partie d'emmanchement à la presse comprise entre l'arbre et la bague intérieure ne dépasse pas 1/3 du diamètre de l'arbre.
