Abstract
A vibration damping assembly for use with a second shaft nested within an interior of a first shaft is provided including a collar rotatable with the first shaft, and a cage rotatable with the second shaft and having at least one window formed therein. The collar and the cage are mounted concentrically. At least one damping mechanism is positioned within the at least one window. The at least one damping mechanism includes at least one flyweight and at least one support wedge. The at least one flyweight movable relative to the cage to frictionally engage an adjacent surface of the collar.
Claims11
A vibration damping assembly for use with a first shaft and a second shaft, the second shaft nested within an interior of the first shaft, the vibration damping assembly comprising:
- a collar rotatable with the first shaft;
- a cage rotatable with the second shaft and having at least one window formed therein, wherein the collar and the cage are mounted concentrically, the collar being rotatable relative to the cage;
- and
- at least one damping mechanism positioned within the at least one window, the at least one damping mechanism including a plurality of flyweights and at least one support wedge, the at least one support wedge being positioned between and in contact with the plurality of flyweights, wherein the plurality of flyweights are movable radially relative to the cage to frictionally engage an adjacent surface of the collar.
