Title (EN) MOVABLE RING ASSEMBLY FOR A TURBINE ENGINE TURBINE
(FR) ASSEMBLAGE D'ANNEAU MOBILE DE TURBINE DE TURBOMACHINE
Abstract:
(EN) A movable ring assembly (4) for a turbine engine turbine (10) that is mounted between two successive rotor discs (20a) and (20b) of said turbine (10), said rotor discs (20a) and (20b) being fixed to each other by bolting, characterised in that it comprises: - a fixing ferrule (44) fixed between the upstream (20a) and downstream (20b) discs by the bolting thereof; a part forming a movable ring (42), said part supporting radial sealing members (32) and being fixed between the upstream disc (20a) and the ferrule (44); - and a seal (46) interposed between said part forming the movable ring (42) and the ferrule (44).
(FR) Assemblage d'anneau mobile (4) de turbine (10) de turbomachine qui est monté entre deux disques de rotor (20a) et (20b) successifs de ladite turbine (10), lesdits disques de rotor (20a) et (20b) étant fixés l'un sur l'autre par boulonnage, caractérisé en ce qu'il comprend : - une virole (44) de fixation fixée entre les disques amont (20a) et aval (20b), par le boulonnage de ceux-ci, - une pièce formant anneau mobile (42), ladite pièce portant des léchettes radiales d'étanchéité (32) et étant fixée entre le disque amont (20a) et la virole (44), - un joint d'étanchéité (46) interposé entre ladite pièce formant anneau mobile (42) et la virole (44).
