Abstract
A thrust bearing for supporting a rotating shaft. Rotation of the shaft generates a hydrodynamic film of lubricating fluid between a thrust runner mounted on the shaft and a bearing pad disposed within a bearing housing. A restrictor-compensated channel extending through the bearing pad conducts a portion of the pressurized lubricating fluid from the hydrodynamic film into a pocket, or cavity, disposed on that surface of the bearing pad adjacent the bearing housing. Conduction of pressurized lubricating fluid from the hydrodynamic film into the pocket produces a hydrostatic film of lubricating fluid between the bearing pad and the bearing housing to support the bearing pad away from the bearing housing. Further, a step, or notch, is disposed on the surface of the bearing pad adjacent the thrust runner to both increase the load-carrying capacity of the bearing and to obviate the necessity of the bearing pad tilting to generate the hydrodynamic film.
