Abstract

L'invention se rapporte à un anneau (16) de rétention axiale d'aubes pour une roue mobile (20) de turbomachine, la roue mobile comprenant : - un disque (21) comportant des rainures (58) de logement d'aubes ; - une pluralité d'aubes (18) comprenant chacune une pale (30), et un pied (24) agencé dans l'une des rainures (58) du disque (21). Selon l'invention, l'anneau comprend au moins un système de maintien (72) configuré pour maintenir l'anneau (16) axialement par rapport au disque (21), le système de maintien (72) comprenant un organe de verrouillage (74) monté pivotant sur l'anneau (16) et configuré pour être déplacé entre une position de déverrouillage, et une position de verrouillage dans laquelle une extrémité de verrouillage (84) de l'organe de verrouillage (74) est destinée à coopérer axialement avec le disque (21).The invention relates to a ring (16) for axial retention of blades for a movable wheel (20) of a turbomachine, the movable wheel comprising: - a disc (21) comprising grooves (58) for housing the blades; - a plurality of blades (18) each comprising a blade (30), and a root (24) arranged in one of the grooves (58) of the disc (21). According to the invention, the ring comprises at least one holding system (72) configured to hold the ring (16) axially relative to the disc (21), the holding system (72) comprising a locking member (74 ) pivotally mounted on the ring (16) and configured to be moved between an unlocked position, and a locking position in which a locking end (84) of the locking member (74) is intended to cooperate axially with the disc (21).
