Abstract

Le présent document concerne un ensemble (36a, 36b) d’axe longitudinal comprenant un palier (40) de roulements (50) comportant une bague interne (42) solidaire d’un arbre (38) et une bague externe (44) reliée fixement à un support statorique (46), la bague externe (44) comprend une première partie (48) annulaire coopérant avec la bague interne (42) pour le guidage des roulements (50), cette première partie (48) étant reliée à une seconde partie (42) annulaire fixée au support statorique, cette seconde partie (42) présentant au moins une zone annulaire (54) ayant une rigidité en direction radiale inférieure à la rigidité en direction radiale de la première partie (48) et en ce qu’il comprend des premiers moyens d’étanchéité (72a) portés par la bague externe (44) et coopérant avec des seconds moyens (72b) d’étanchéité portés par l’arbre (38). Figure à publier avec l’abrégé : Figure 2.
