Claim 13:
14. A damping device for damping bending vibration of a shaft rotatable about an axis of rotation, the damping device coupled with a support structure, the damping device comprising:
a housing defining a chamber configured to receive a damping fluid; and
a damping disc operatively coupled with the shaft and at least partially received within the chamber, wherein the damping disc is configured to wobble within the chamber about a first axis orthogonal to the axis of rotation and a second axis orthogonal to the first axis and the axis of rotation to move the damping fluid along a direction substantially parallel to the axis of rotation for damping bending vibration of the shaft,
wherein the housing comprises an inlet port through which the damping fluid enters the chamber and an outlet port through which the damping fluid exits the chamber, and wherein the chamber is in fluid communication with a circulation system configured for circulating the damping fluid into the chamber through the inlet port and out of the chamber through the exit when the shaft is rotated about the axis of rotation.
