Squeeze film damper

摘要

A squeeze film damper is provided, which includes a bearing cartridge (6), a housing (4), in which the bearing cartridge (6) is accommodated, and a squeeze film in a gap (22) between the housing (4) and the bearing cartridge (6) for producing a damping force directed opposite a circulating radial exciter force, which is generated by an imbalance retained in the bearing cartridge (6). In the squeeze film damper, an arrangement (28) for attenuating the damping force according to the circumferential position are provided around the bearing cartridge (6).

主权项

1. A squeeze film damper comprising a bearing cartridge, a housing in which the bearing cartridge is held, a squeeze film in a gap between the housing and the bearing cartridge for generating a damping force directed against an all-around radial excitation force that is generated by an imbalance held in the bearing cartridge, a first circumferential position-dependent portion formed on an outer contour of the bearing cartridge for weakening the damping force around the bearing cartridge.
