Abstract
A generator assembly may include a bearing liner and a bearing retainer configured to reduce vibration response in a bearing assembly under high frequency operation of a rotor. The bearing liner may be configured to provide a clearance between the bearing assembly and an adjacent housing/bearing liner to prevent high vibration output from the bearing assembly on for example, the rotor shaft. The bearing retainer may include a recess to accommodate axial movement of the bearing assembly in response to rotation of the rotor. In some embodiments, the bearing retainer may include a dampener to dampen contact of the bearing assembly with the retainer.
