Abstract

A film squeeze damper for a thrust bearing includes a plurality of curved beam segments each having a fluid chamber adjacent the support housing and mounted end to end to surround the thrust bearing. Side mounted nibs transmit the thrust load from a radial dependent member of the outer race to the support housing through each segment. This permits unrestrained radial damping of vibratory energy occasioned by the unbalance in the supported shaft. A mechanical stop is provided by the design to limit radial deflection of the segment during a high rotor unbalance.
