Theoretical Study of Hydrostatic Thrust Bearings

Abstract

Concerning three types of hydrostatic bearing i.e., spherical, discal or conical, the theoretical solutions of pressure distribution, quantity of flow, load capacity and power consumption are obtained. Depending on these solutions, it is clarified that the bearing clearance is determined by the dimensions of the inherent restrictor. Therefore, the designing factors of the bearing as to the clearance, the restrictor, the pocket and the supplying fluid pressure, taking into consideration the conditions of the optimum dynamic stability, the maximum load capacity and the minimum power consumption have been investigated.
