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).
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).
