Abstract

Une turbomachine comprend un arbre de rotor et un palier à roulement supportant l'arbre en rotation selon un axe. Le palier comprend une bague intérieure, une bague extérieure, et des éléments roulants engagés entre la bague intérieure et la bague extérieure. La bague intérieure présente une première portion annulaire d'extrémité axiale davantage exposée à la chaleur en fonctionnement qu'une seconde portion annulaire d'extrémité axiale. La turbomachine comprend en outre un dispositif d'injection d'huile configuré pour alimenter en huile les éléments roulants de manière à assurer la lubrification de ceux-ci. Pour homogénéiser la température de la bague intérieure, celle-ci comporte des orifices traversants formés dans la première portion annulaire d'extrémité axiale et répartis autour de l'axe pour permettre une circulation d'huile issue du dispositif d'injection d'huile au travers de la première portion annulaire d'extrémité axiale.
