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 en une première zone d’appui s’étendant sur un premier secteur angulaire autour de l’axe longitudinal,○ une deuxième partie d’appui (22) venant en appui sur le premier rotor en une deuxième zone d’appui, différente de la première zone d’appui, la deuxième zone d’appui s’étendant sur un deuxième secteur angulaire autour de l’axe longitudinal, le deuxième secteur angulaire étant inférieur au premier secteur angulaire.
