Abstract

Le présent exposé concerne un ensemble rotatif pour turbomachine permettant un meilleur contrôle du jeu radial entre deux pièces coaxiales. Il comprend un rotor comportant au moins deux étages rotoriques consécutifs (10a, 10b) munis d'une pluralité d'aubes mobiles (20), et une virole de rotor (50), annulaire, reliant lesdits deux étages rotoriques consécutifs (10a, 10b); un stator comportant au moins un étage statorique (11), muni d'une pluralité d'aubes fixes (30), prévu entre lesdits deux étages rotoriques consécutifs (10a, 10b), et un anneau de stator (60), annulaire, monté sur lesdites aubes fixes (30) ; l'un (50) des éléments parmi la virole de rotor et l'anneau de stator porte au moins une léchette (51) configurée pour coopérer avec une piste abradable (62) portée par l'autre (60) desdits éléments ; la virole de rotor (50) comporte, à chacune de ses extrémités amont et aval, soit une portion de contact du type axial (52, 53) s'étendant au-dessous d'une butée (71, 72) de l'étage rotorique correspondant, soit une portion de contact du type oblique reposant sur une surface d'appui oblique de l'étage rotorique correspondant.
