Abstract

Flasque de rotor de turbomachine, notamment de turbine à flux axial. La jante 8 d'un disque de turbine 1 est pourvue d'une collerette circulaire 24 sur laquelle est engagé le talon d'un flasque annulaire 10 à section en U à branches inégales qui coiffe la collerette. Le flasque annulaire est divisé en deux secteurs inégaux, à savoir une pièce principale formant circlip et une pièce plus petite formant une clé qui complète le flasque après mise en place du circlip, les découpes des extrémités de la clé la retiennent en place. Application aux turbines à gaz.
