Abstract
The present invention relates to a turbomachine assembly, comprising: a casing (), a first rotor () which is movable in rotation with respect to the casing () about a longitudinal axis (X-X), and comprising: *a disk (), and *a plurality of blades () capable of flapping with respect to the disk () during a rotation of the first rotor () with respect to the casing (), a second rotor () which is movable in rotation with respect to the casing () about the longitudinal axis (X-X), and a damper () which is configured to damp a displacement of the first rotor () with respect to the second rotor () in a plane orthogonal to the longitudinal axis (X-X), the displacement being caused by a flapping of at least one blade () among the plurality of blades (), the damper () comprising: o a first bearing part (): *bearing against the first rotor (), and *being configured to apply a first centrifugal force (C) to the first rotor (), o a second bearing part (): *bearing against the second rotor (), and *being configured to apply a second centrifugal force (C) on the second rotor (), and o a linking part (): *connecting the first bearing part () to the second bearing part (), and being thinned relative to the first bearing part () and the second bearing part (), and o a flyweight () which is fixedly mounted on the damper ().
