ABSTRACT:
A hydrodynamic fluid film thrust bearing including a stationary thrust plate 15, a rotating thrust runner 20 spaced therefrom, and at least one foil 50 disposed therebetween, is provided with first and second sets 25 and 45 of overlying resilient backing members in axial alignment with the foil. One of the backing members 25, having a lower relative spring constant, provides the bearing with compliance for adequate load capacity and damping characteristics. The other backing member 45, having a higher relative spring constant, establishes and maintains an optimum fluid film geometry under all loading, speed and other operating conditions.
