Abstract (en)
[origin: WO2019122691A1] The invention concerns an assembly (1) for a turbomachine comprising: - a first rotor module (2) comprising a first blade (20), - a second rotor module (3), linked to the first rotor module (2), and comprising a second blade shorter than the first blade (20), and - a damper device (4) extending according to at least one component along a longitudinal axis (X-X) of the turbomachine, characterised in that the damper device (4) is annular, extending circumferentially around the longitudinal axis (X-X) of the turbomachine, and in that the damper device (4) comprises a first outer radial surface (40) that presses and rubs against the first module (2) and a second outer radial surface (42) that presses and rubs against the second module (3), so as to couple the modules (2, 3) with the aim of damping their respective vibratory motions during operation.
