Abstract

L'invention concerne une pièce (80) annulaire de support d'un planétaire externe (38) dans un train d'engrenage épicycloïdal, comprenant une première bride annulaire radiale (66) formée à une première extrémité axiale et une seconde bride annulaire radiale (68) formée à une seconde extrémité axiale, la première bride annulaire (66) et la seconde bride annulaire (68) étant reliées à l'une à l'autre par une paroi annulaire de liaison (78). Selon l'invention, la paroi annulaire de liaison (78) comprend une portion de jonction à la seconde bride (68) qui forme un renflement annulaire (76) entourant la seconde bride annulaire (68).
