Abstract

Turbomachine comportant un arbre, un palier de maintien de l'arbre, comportant une bague externe, un support (20) pour ledit palier, sur une bride (36) duquel est fixée la bague externe par des boulons ; chaque boulon comportant une vis de maintien (146) et un écrou (150) vissés ensemble ; la turbomachine comportant en outre pour chaque boulon, des moyens de maintien en position (158) de la vis de maintien, aptes à maintenir celle-ci en position fixe par rapport au support de palier ou à la bague externe, même en l'absence de l'écrou (150). Boulon pour une telle turbomachine. La tête de la vis de maintien avec les moyens de maintien peut être de faibles dimensions, grâce à quoi la fixation de la bride sur le support de palier et donc le poids de cette fixation peuvent être optimisés.
