Abstract
L’invention concerne un ensemble (34, 72) d’axe longitudinal comprenant : - un arbre (38) et une partie statorique (40), - un premier palier (42, 44) comprenant une bague interne (42a, 44a) et une bague externe (42b, 44b) fixées pour l’une à l’arbre (38) et pour l’autre à la partie statorique (40), - un second palier (42, 44) espacé axialement du premier palier (42, 44) et comprenant une bague interne (42a, 44a) et une bague externe (42b, 44b) fixée à pour l’une à l’arbre et l’autre à la partie statorique (40), dans lequel des premiers moyens élastiques (62) assurent une précontrainte sur une première face axiale (58) de l’une première statorique des bagues interne (42a, 44a) et externe (42b, 44b) du premier palier (42, 44) de manière à maintenir ladite première bague statorique du premier palier (42, 44) à distance axiale avec un jeu J avec une butée axiale (58, 80) de la partie statorique (40), ce jeu étant apte à être consommé en cas d’inversion de poussée.
