Abstract

L'invention concerne un dispositif (10) pour le centrage et le guidage en rotation selon un axe (X) d'un arbre de turbomachine, comprenant un palier de roulement comprenant une bague de roulement (14), un support de palier (16), et une bague frettée (24) montée radialement entre le support de palier (16) et la bague de roulement (14), et un circuit d'alimentation en huile adapté pour alimenter en huile un film d'huile entre la bague extérieur (14) et la bague frettée, le circuit comprenant un canal d'alimentation formé dans le support de palier (16) et dont une sortie débouche entre le support de palier (16) et la bague frettée (24) à distance de l'espace annulaire, et au moins une rainure, chaque rainure s'étendant axialement entre le support de palier (16) et la bague frettée (24) depuis la sortie du canal d'alimentation jusqu'à une sortie de rainure faisant face à un trou traversant de la bague frettée (24).
