Abstract

Le turbocompresseur (1) comporte un arbre d'entraînement (3) ; au moins un rouet (7) relié à l'arbre d'entraînement (3) ; un moteur électrique (8) configuré pour entraîner en rotation l'arbre d'entraînement (3) ; un agencement de palier de butée configuré pour limiter un mouvement axial de l'arbre d'entraînement (3) ; un manchon de palier (16) comportant une partie de palier radial (18) configuré pour supporter en rotation l'arbre d'entraînement (3), une partie de manchon (19) entourant la partie de palier radial (18) et comportant une face d'extrémité axiale qui est tournée vers l'au moins un rouet (7) et une surface de contact (23) qui est située au niveau de la face d'extrémité axiale et qui est configurée pour coopérer avec l'agencement de palier de butée ; un espacement annulaire (21) formé entre la partie de palier radial (18) et la partie de manchon (19), et une zone de refroidissement (31) formée dans une surface circonférentielle externe (32) de la partie de manchon (19). La partie de manchon (19) comporte des entailles réparties autour de l'axe longitudinal du manchon de palier (16) et débouchant dans la surface de contact (23).
