ABSTRACT:
A flexible damped bearing arrangement for rotatably mounting a shaft wherein the shaft bearing is supported within a movable member suspended from a stationary frame by means of a series of resilient springs adapted to permit the member to move radially in reference to the shaft. A squeeze film cavity, provided with high pressure fluid, is established between the movable member and the stationary frame to dampen the bearing's response to the shaft. Seals are provided outside the damping cavity and are arranged to act perpendicular to the direction of movement of the member whereby the interaction of the seals with the squeeze film damping is substantially minimized.
