Abstract

L'invention concerne un compresseur à engrenage (GCO) comprenant un engrenage (GE) et au moins un compresseur (CO1) réalisé sous la forme d'un turbocompresseur. L'engrenage (GE) comporte un arbre d'entraînement de compresseur (COSH) assurant l'entraînement du compresseur (CO1), lequel arbre d'entraînement de compresseur (COSH) est relié de manière à transmettre un couple de rotation à une roue à aubes (IMPCO) du compresseur (CO1) pouvant tourner autour d'un axe de rotation (X). Le compresseur (CO1) comporte un carter de compresseur (CASCO), le carter de compresseur (CASCO) comportant des déformations (SUPCAS1, SUPCAS2) destinées à prendre appui sur des supports (SUPP1, SUP2) du compresseur à engrenage (GCO). L'invention vise à simplifier le montage. A cet effet, des éléments paliers (BE) permettant une mobilité relative sont placés entre les déformations (SUPCAS1, SUPCAS2) et les supports (SUP1, SUP2) et sont réalisés de telle manière que le carter de compresseur (CASCO) est monté de manière mobile dans le sens axial. L'invention concerne par ailleurs un procédé de montage associé.
