Abstract
Abstract A hydrostatic bearing in which one of the opposed bearing members has a plurality of part-pockets in it into all of which the hydrostatic fluid is pumped and each of which is surrounded by a ridge. When an impact load is applied to the bearing, the hydrostatic fluid flows out through the gaps between the ridges of the one bearing member and the opposed bearing member into drainage grooves provided in the one bearing member which are disposed between adjacent ridges, and is recirculated.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
163 words
A hydrostatic bearing comprising two bearing members mounted for relative movement therebetween, and with their cooperating bearing portions in opposed relation, the bearing portion of one of said members having a pocket therein which is subdivided into and consists of a plurality of pressure fluid part-pockets separated from one another and each surrounded by a separating throttle ridge, which cooperates with the bearing portion of the other member, said bearing portion of said one member having drainage grooves therein disposed between the ridge portions of adjoining partpockets, and means connecting said part-pockets to a source of pressure fluid for maintaining said bearing portions in spaced relation with a gap therebetween during use, comprising a pressure fluid supply conduit, a plurality of pressure fluid supply ducts con-nected to said supply conduit and equal in number to said part-pockets, one being connected to each separate part-pocket, and a single throttle member disposed in said supply conduit to stabilize the fluid pressure in all said ducts.
Claim 2
Dependent Claim
163 words
A hydrostatic bearing comprising two bearing members mounted for relative movement therebetween, and with their cooperating bearing portions in opposed relation, the bearing portion of one of said members having a pocket therein which is subdivided into and consists of a plurality of pressure fluid part-pockets separated from one another and each surrounded by a separating throttle ridge, which cooperates with the bearing portion of the other member, said bearing portion of said one member having drainage grooves therein disposed between the ridge portions of adjoining partpockets, and means connecting said part-pockets to a source of pressure fluid for maintaining said bearing portions in spaced relation with a gap therebetween during use, comprising a pressure fluid supply conduit, a plurality of pressure fluid supply ducts con-nected to said supply conduit and equal in number to said part-pockets, one being connected to each separate part-pocket, and a single throttle member disposed in said supply conduit to stabilize the fluid pressure in all said ducts.
Claim 3
Dependent Claim
45 words
A hydrostatic bearing as claimed in claim 1, wherein said part-pockets are of equal size and of rectangular configuration in cross section and are disposed with their elongated lateral sides in parallelism, and said drainage grooves are disposed between the adjacent sides of adjoining part-pockets.
