Title (EN) SPOKE LOCKING ARCHITECTURE
(FR) ARCHITECTURE DE VERROUILLAGE DE RAYONS
Abstract:
(EN) A spoke locking arrangement comprising a washer seated in a seat defined in a structural ring of a gas turbine engine, the washer having a portion thereof plastically deformed into an anti-rotation notch defined in the structural ring, thereby locking the washer against rotation in the seat, the washer further comprising a set of holes for receiving corresponding bolts, and wherein the washer further has at least one anti- rotation tab at each hole, the anti-rotation tabs being deformable in engagement with the bolts to individually lock the same against rotation.
(FR) La présente invention concerne un ensemble de verrouillage de rayons comprenant une rondelle assise dans un siège défini dans un anneau de structure d'un moteur à turbine à gaz, la rondelle ayant une partie de celle-ci déformée plastiquement dans une encoche anti-rotation définie dans l'anneau de structure, la rondelle comprenant en outre un ensemble de trous pour recevoir des boulons correspondants, et la rondelle comportant en outre au moins une patte anti-rotation au niveau de chaque trou, les pattes anti-rotation étant déformables en prise avec les boulons pour verrouiller individuellement ceux-ci contre la rotation.
