Abstract

Bague d’amortissement de vibrations pour pivot d’aube de redresseur à calage variable de turbomachine, palier et aube de redresseur comportant une telle bague Un aspect de l’invention concerne une bague pour pivot d’aube de redresseur à calage variable de turbomachine, comportant une partie extérieure (21) assurant la rigidification de la bague et une partie intérieure (22) solidaire de la partie extérieure et assurant une fonction d’amortissement. Un autre aspect de l’invention concerne un palier pour pivot d’aube de redresseur à calage variable de turbomachine monté dans un alésage d’un carter de la turbomachine et comportant une douille, solidaire dudit alésage et permettant une rotation d’une tige pivot au sein du carter, et la bague montée solidaire de la tige pivot à l’intérieur de la douille. L’invention concerne aussi une aube de redresseur à calage variable comportant le palier ci-dessus et une turbomachine comportant de telles aubes. Figure à publier avec l’abrégé : Figure 3
