Abstract

L'invention concerne un assemblage comportant un disque aubagé monobloc (1), au moins un rotor (2) de compresseur basse pression de turbomachine et un arbre de compresseur basse pression, caractérisé en ce que le disque aubagé et le rotor (2) de compresseur basse pression sont l'un et l'autre adaptés pour être emmanchés sur l'arbre de compresseur basse pression et fixés mécaniquement sur celui-ci par des jeux de cannelures. Au moins un organe de serrage (16) bloque axialement les différentes viroles par rapport à l'arbre.
