Claim 0:
1. A turbomachine, comprising:
a shaft rotatable about an axis of rotation;
a support structure; and
a damping device positioned between the support structure and the shaft, 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 such that the damping fluid absorbs bending vibration emitted by the shaft;
wherein the turbomachine defines a radial direction extending orthogonal to and from the axis of rotation, and wherein the damping disc has a thickness defined between a first face and a second face opposing the first face, and wherein the damping disc comprises a hub portion defining a pass-through aperture through which the shaft extends, and wherein the damping disc extends outward from the hub portion to an outer periphery along the radial direction, and wherein the thickness of the damping disc gradually changes from the hub portion to the outer periphery.
