Abstract

La présente invention concerne un ensemble pour turbomachine comprenant :- un premier rotor comprenant une pluralité d’aubes (122) comprenant chacune une échasse (1224),- un deuxième rotor,- un amortisseur (2) configuré pour amortir un déplacement du premier rotor par rapport au deuxième rotor l’amortisseur (2) comprenant deux griffes (22) s’étendant de part et d’autre d’une échasse (1224) d’une aube (122) parmi la pluralité d’aubes (122), de sorte à enserrer l’échasse (1224), une cavité étant ménagée au sein de l’une au moins des deux griffes (22), la cavité débouchant sur l’échasse (1224), et- une cale logée au sein de la cavité et configurée pour venir en butée contre l’échasse (1224) de sorte à renforcer l’enserrement de l’échasse (1224) par les deux griffes (22).
