Abstract (en)
[origin: WO2020239804A1] The present invention relates to a turbomachine assembly, comprising: - a casing (10), - a first rotor (12) which is movable in rotation with respect to the casing (10) about a longitudinal axis (X-X), and comprising: * a disk (120), and * a plurality of blades (122) capable of flapping with respect to the disk (120) during a rotation of the first rotor (12) with respect to the casing (10), - a second rotor (140) which is movable in rotation with respect to the casing (10) about the longitudinal axis (X-X), and - a damper (2) which is configured to damp a displacement of the first rotor (12) with respect to the second rotor (140) in a plane orthogonal to the longitudinal axis (X-X), the displacement being caused by a flapping of at least one blade (122) among the plurality of blades (122), the damper (2) comprising: o a first bearing part (21): * bearing against the first rotor (12), and * being configured to apply a first centrifugal force (C1) to the first rotor (12), o a second bearing part (22): * bearing against the second rotor (140), and * being configured to apply a second centrifugal force (C2) on the second rotor (140), and o a linking part (20): * connecting the first bearing part (21) to the second bearing part (22), and being thinned relative to the first bearing part (21) and the second bearing part (22), and o a flyweight (3) which is fixedly mounted on the damper (2).
