Abstract

L’invention concerne un ensemble (101) comprenant une aube (103) et un système (105) de maintien de l'aube (103), pour une turbomachine d’aéronef. Le système (105) comprend un pivot (113) configuré pour réaliser une rotation selon l’axe (A) et une bride annulaire (117), montée sur le pivot (113) et configurée pour recevoir le pied (111) en son sein. Le pied (111) a une section transversale à l’axe (A) de forme elliptique et est positionné dans un logement (119) interne du pivot (113) de forme complémentaire. L’ensemble (101) comprend en outre un dispositif compressible (121), positionné au fond du logement (119) et comprimé par une base (123) du pied (111) et une douille (125), positionnée dans le logement (119) du pivot (113) entre le pivot (113) et la bride annulaire (117) d’une part, et entre le pivot (113) et le pied (111) d’autre part.
