ABSTRACT:
Device for damping vibrations in a rotating turbomachine rotor is formed of an assembly of a plurality of centrally apertured rotor discs force-lockingly clamped together by a tie-rod passing through the apertures of the rotor discs and damping elements disposed in a ring slot formed between the tie-rod and the inner periphery of the rotor discs, the damping elements being actuatable for damping vibrations in the rotor in dependence upon centrifugal force generated by the rotating rotor. The damping elements are formed of ring segments uniformly distributed peripherally in the ring slot and having discrete, strip-like contact surfaces at radially inner and outer peripheral surfaces thereof, the contact surfaces being in contact with the tie-rod and the rotor discs, respectively, the contact surfaces being spaced from one another in longitudinal direction of the respective damping elements and in a region of the respective damping elements beyond which the center of gravity of the respective damping elements is located.
