Abstract

Arrêt axial aval pour bague externe de palier L’invention concerne une enceinte (26) de turbomachine (10) comprenant un arbre moteur (16) de la turbomachine (10) en rotation autour d’un axe (X) longitudinal au moyen de deux paliers à roulements (22, 24), un palier amont (22) et un palier aval (24), le palier amont (22) comportant une bague interne (28a) et une bague externe (29a), la bague externe (29a) étant reliée d’une part, à un support de palier amont (32a) et d’autre part, à une bride de stabilisation (33) qui est reliée avec le support de palier (32a) aval de la bague externe (28a). Selon l’invention, la bride de stabilisation (33) et le support de palier amont (32a) sont reliés par embrèvement de manière à retenir axialement la bride (33) par rapport au support de palier amont (32a), et l’enceinte (26) comprend en outre au moins un élément circulaire formant butée axiale aval (40) de la bride de stabilisation.
