Title: Hydrostatic bearing assembly
IPC: F16C32/06
Filed: 1971-04-19
Abstract: 1,274,165. Fluid bearings. IKEGAI TEKKO K.K. 19 April, 1971 [26 Feb., 1970], No. 21885/71. Heading F2A. A hydrostatic bearing has pressurized fluid fed to pockets 91 defined by walls 7 which provide the bearing surfaces 9, the fluid flowing from the pockets across the surfaces, the path having a part which is elastically deformable by the pressure in the pocket so as to restrict the flow of fluid in response to an increase in pressure in the pocket. The restriction in the flow serves to assist the realignment of the bearing members if they are displaced from their normal positions since pressurized fluid is trapped in the pocket and a greater load is exerted between the members. The walls of the pockets may be narrowed at their bases in order that they may pivot in response to the pressure in the pocket. In alternative embodiments (Figs. 6 and 8, not shown) fluid is fed from the pocket to a chamber behind the bearing surfaces so as to urge the surfaces towards the other bearing member thereby restricting the flow of fluid from a pocket on increase of pressure in that pocket.
