Abstract

La présente invention concerne un ensemble pour turbomachine comprenant :- un premier rotor comprenant :○ un disque (120), et○ une pluralité d’aubes (122) susceptibles de battre par rapport au disque (120),- un deuxième rotor (140), et- un amortisseur (2) configuré pour amortir un déplacement du premier rotor par rapport au deuxième rotor (140), dans un plan orthogonal à l’axe longitudinal, l’amortisseur (2) comprenant :○ une première partie d’appui (21) venant en appui sur le premier rotor,○ une deuxième partie d’appui (22) venant en appui sur le deuxième rotor (140), et○ une partie de liaison (20) :* reliant la première partie d’appui (21) à la deuxième partie d’appui (22), et* étant amincie par rapport à la première partie d’appui (21) et à la deuxième partie d’appui (22). Figure pour l’abrégé : Fig. 3
