Abstract
Abstract A hydrostatic bearing is constructed as a self-contained unit, including an outer bearing ring, an inner bearing ring, a support ring beneath the bearing rings for supporting the same, a plurality of pressure-oil chambers between the respective rings with these chambers being of different dimensions in dependence upon whether they are to counteract an axial, radial or tilting force component, and oil passages which communicate separately with the chambers for filling the same with oil under pressure.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
114 words
A hydrostatic bearing capable of withstanding simultaneous axial, radial and tilting force components, comprising a selfcontained unit including an outer bearing ring, an inner bearing ring at least partially accommodated within the inner circumference of said outer bearing ring, a support ring beneath said bearing rings for supporting said bearing rings, a plurality of hydraulic pressure fluid chambers between the respective rings for counteracting said force components and being dimensioned in dependence upon which of said force components said chambers are tO counteract, and hydraulic fluid passages communicating with said chambers for feeding said chambers with hydraulic fluid under pressure, said passages being adapted for connection with a source of hydraluic fluid under pressure.
Claim 2
Dependent Claim
114 words
A hydrostatic bearing capable of withstanding simultaneous axial, radial and tilting force components, comprising a selfcontained unit including an outer bearing ring, an inner bearing ring at least partially accommodated within the inner circumference of said outer bearing ring, a support ring beneath said bearing rings for supporting said bearing rings, a plurality of hydraulic pressure fluid chambers between the respective rings for counteracting said force components and being dimensioned in dependence upon which of said force components said chambers are tO counteract, and hydraulic fluid passages communicating with said chambers for feeding said chambers with hydraulic fluid under pressure, said passages being adapted for connection with a source of hydraluic fluid under pressure.
Claim 3
Dependent Claim
29 words
A hydrostatic bearing as defined in claim 1, wherein respective ones of said chambers and passages are provided in said outer and inner bearing rings and said support ring.
Claim 4
Dependent Claim
48 words
A hydrostatic bearing as defined in claim 1, said inner bearing ring and said support ring having exposed surfaces; further comprising layers of synthetic plastic material on said exposed surfaces; and wherein said chambers and some of said passages are formed in said layers of synthetic plastic material.
Claim 5
Dependent Claim
25 words
A hydrostatic bearing as defined in claim 3, the remainder of said passages being formed in said inner bearing ring and said support ring, respectively.
Claim 6
Dependent Claim
17 words
A hydrostatic bearing as defined in claim 3, wherein said synthetic plastic material is an epoxy resin.
Claim 7
Dependent Claim
16 words
A hydrostatic bearing as defined in claim 1, wherein said passages communicate separately with said chambers.
Claim 8
Dependent Claim
14 words
A hydrostatic bearing as defined in claim 1, wherein said hydraulic fluid is oil.
