Abstract
La présente invention concerne un ensemble pour turbomachine comprenant : Un disque rotor (1) pourvu d’une alvéole (10), Une aube (12) présentant un pied d’aube (120), ledit pied d’aube (120) étant logé au sein de l’alvéole (10), Un anneau de retenue (2) : Etant configuré pour empêcher un mouvement axial du pied d’aube (120) au sein de l’alvéole (10), et Présentant : Une partie radialement interne (20) pourvue d’un premier organe anti-rotation (200), et Une partie radialement externe (22), Un anneau de maintien (3), ledit anneau de maintien (3) : S’étendant autour d’un axe longitudinal (X-X) de turbomachine, Etant configuré pour empêcher un mouvement axial de l’anneau de retenue (2), et Comprenant un organe anti-rotation d’anneau de maintien (300) configuré pour coopérer avec le premier organe anti-rotation (200), de sorte à empêcher une rotation de l’anneau de retenue (2) autour de l’axe longitudinal (X-X). Figure pour l’abrégé : Fig. 2The present invention relates to an assembly for a turbomachine comprising: a rotor disc (1) provided with a cell (10), a blade (12) having a blade root (120), said blade root (120) being housed within the cell (10), A retaining ring (2): Being configured to prevent axial movement of the blade root (120) within the cell (10), and Having: A radially inner part (20) provided with a first anti-rotation member (200), and A radially outer part (22), A retaining ring (3), said retaining ring (3): Extending around a longitudinal axis (XX) of a turbomachine, being configured to prevent axial movement of the retaining ring (2), and comprising a retaining ring anti-rotation member (300) configured to cooperate with the first anti-rotation member (200 ), so as to prevent rotation of the retaining ring (2) around the longitudinal axis (XX). Figure for the abstract: Fig. 2
