ABSTRACT:
A compliant hydrodynamic fluid film bearing made of three or more pads, each having a thin, flexible bearing sheet supported by a resilient support element fastened to a mount. A set of split, tiered stiffener sheets is fastened between the bearing sheet and the support element to provide an increasing stiffness gradient to the pad from its leading to trailing edges. The support element includes a plurality of resilient elevations that also increase in stiffness toward the trailing edge for the same purpose. The pad profile changes with changing hydrodynamic loading to present an optimal profile for maximal load carrying over the full speed range of the bearing.
