Abstract (en)
[origin: WO2020239803A1] Disclosed is an assembly for a turbomachine comprising: • a first rotor comprising: • a disc (120), and • a plurality of vanes (122) capable of fluttering relative to the disc (120), • a second rotor (140), and • a damper (2) configured to dampen a movement of the first rotor relative to the second rotor (140), in a plane orthogonal to the longitudinal axis, the damper (2) comprising: • a first bearing portion (21) that comes to bear on the first rotor in a first bearing zone extending over a first angular sector around the longitudinal axis, • a second bearing portion (22) that comes to bear on the first rotor in a second bearing zone extending over a second angular sector around the longitudinal axis, and • a third bearing portion (23) that comes to bear on the second rotor (140).
