BRIDGE SPRING CENTERING DEVICE FOR SQUEEZE FILM DAMPERS

摘要

A damper film bearing assembly (10) for supporting a rotatable shaft (14) includes a bearing housing (16) having a longitudinal opening passing therethrough for receiving the rotatable shaft (14). The bearing housing (16) also has at least one radial recess (42) formed in an outer surface thereof. At least one resilient element (30) is disposed within the recess (12) in the bearing housing (16) above the floor of the recess (42), the resilient element (30) biasing the support piston away from the axis of the rotatable shaft (14). The resilient element in accordance with the disclosure may be a bridge spring or a rod spring as appropriate.
