Abstract

Ensemble rotorique de soufflante d’une turbomachine (10) d’axe longitudinal (X) comprenant un rotor (40) configuré pour être mobile en rotation autour de l’axe longitudinal, le rotor comportant une virole de support (42b) ; un cône amont (30) agencé en amont du rotor, le cône amont présentant une face radialement externe délimitant, radialement à l’intérieur, une surface d’écoulement d’air ; un dispositif d’équilibrage (50) intercalé longitudinalement entre le cône amont et la virole de support du rotor ; des moyens de blocage du cône amont à la virole de support du rotor, ces moyens de blocage étant configurés pour maintenir un serrage du dispositif d’équilibrage, dans la direction longitudinale, entre le cône amont et la virole de support.
