Abstract
Le dispositif d'immobilisation en rotation d'un anneau de rétention (20) sur un disque de rotor (10) comporte :
- un premier (162, 262) et un deuxième (164, 264) crochets d'immobilisation successifs du disque (10),
- au moins un taquet (302, 304, 306) dudit anneau de rétention (20), disposé près d'une fente (24) de l'anneau (20).The device for immobilizing a retention ring (20) in rotation on a rotor disc (10) comprises:
a first (162, 262) and a second (164, 264) successive immobilization hooks of the disk (10),
- At least one cleat (302, 304, 306) of said retaining ring (20) disposed near a slot (24) of the ring (20).
La position dudit au moins un taquet (302, 304, 306) sur ledit anneau de rétention (20) est telle que, lorsque ledit anneau de rétention (20) est en place dans une gorge (22) située sur le disque de rotor (10), ledit au moins un taquet (302, 304, 306) est en butée contre ledit premier crochet d'immobilisation (162, 262), et la fente (24) est recouverte par ledit deuxième crochet d'immobilisation (164, 264).
The position of said at least one cleat (302, 304, 306) on said retention ring (20) is such that when said retaining ring (20) is in place in a groove (22) on the rotor disk ( 10), said at least one cleat (302, 304, 306) abuts against said first immobilization hook (162, 262), and the slot (24) is covered by said second immobilization hook (164, 264). ).Applications Claiming Priority (1)
