ABSTRACT:
A hydrodynamic thrust, journal or combined radial and thrust bearing and methods of manufacturing the same. The bearing includes a bearing pad structure that may change shape and move in any direction (six degrees of freedom) to optimize formation of a converging wedge for hydrodynamic operation, equalization of load on the bearing pads in thrust bearings and to adjust for any shaft misalignment. The bearing pad may be formed so as to contact the shaft in the installed state and to deflect under fluid film pressure. The shape of the pads may be altered to achieve desired deformations under load. The pads are supported by a support structure which can include one or more beam-like members. The support structure preferably includes a primary support portion, a secondary support portion and a tertiary support portion.
