Claim 19:
20. A method of damping vibration of a shaft, the method comprising:
rotating the shaft about an axis of rotation;
damping, via a damping device, axial vibration of the shaft; and
damping, via the damping device, overturning moment of the shaft,
wherein the damping device defines a radial direction and an axial direction, the axial direction parallel to the axis of rotation such that the shaft extends longitudinally along the axial direction,
wherein the damping device comprises a bearing operatively coupled with the shaft, a housing, a damper element, and a support structure, wherein the housing is positioned between the support structure and the damper element, wherein the housing and the damper element are complementarily non-rectilinearly shaped to define a curved cavity therebetween for receipt of a damping fluid, wherein the curved cavity comprises legs that extend radially inward, and
wherein the curved cavity is curved in a plane extending along the radial direction and the axial direction and including the axis of rotation.
