Abstract

Le dispositif d'immobilisation en rotation d'un anneau de rétention (20) sur un disque de rotor (10) comporte :
- trois crochets d'immobilisation successifs (62, 64, 66) du disque (10),
- deux taquets (30) de l'anneau de rétention (20), disposés de chaque côté d'une fente (24) de l'anneau de rétention (20).The device for immobilizing a retention ring (20) in rotation on a rotor disc (10) comprises:
three successive immobilization hooks (62, 64, 66) of the disk (10),
- two cleats (30) of the retention ring (20), disposed on each side of a slot (24) of the retention ring (20).

La position des taquets (30) sur l'anneau de rétention (20) est telle que, lorsque l'anneau de rétention (20) est en place dans une gorge (22) située sur le disque de rotor (10), les deux taquets (30) sont en butée respectivement contre le premier et le troisième crochets d'immobilisation (62, 66), et la fente (24) est recouverte par le deuxième crochet d'immobilisation (64).

Figure imgaf001
The position of the catches (30) on the retaining ring (20) is such that, when the retaining ring (20) is in place in a groove (22) on the rotor disk (10), both tabs (30) abut respectively against the first and third locking hooks (62, 66), and the slot (24) is covered by the second locking hook (64).
