Abstract

Abstract A hydrostatic gas bearing system where members are frictionlessly movable relative to each other and where the stabilizing and confining preload force holding said members to movement in a predetermined direction is transmitted through a gas film by floating pads that maintain virtually constant gas film thickness regardless of pressure and which by their floating action compensate for limited dimensional inaccuracies in said members.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 174 words
A hydrostatic gas bearing system using a gas pressure source for frictionless transmittal through a controlled gas film of a balancing force for maintaining close guided relationship between frictionlessly suspended bodies, comprising a. a first carrying body, b. a second body having a guide surface, c. one or more floating pads flexibly mounted and pneumaticaly sealed into first carrying body having opposed surfaces dimensionaly interrelated (d s and d o ) and pneumaticaly interconnected with sealed surface in first carrying body (ch s ) exposed to said gas supply pressure, d. bearing surfaces on said first and second bodies geometricaly located and frictionlessly supported by a gas film to oppose and balance forces frictionlessly transmitted from the floating pads through a gas film (h o ) to the said guide surface on the second body, Said geometric arrangements allowing frictionless movement perpendicular to said forces and in the direction of the bearing surfaces with the floating pad serving to maintain balanced relationship between bearing and guide surfaces and to compensate for limited dimensional variations.
Claim 2
Dependent Claim 174 words
A hydrostatic gas bearing system using a gas pressure source for frictionless transmittal through a controlled gas film of a balancing force for maintaining close guided relationship between frictionlessly suspended bodies, comprising a. a first carrying body, b. a second body having a guide surface, c. one or more floating pads flexibly mounted and pneumaticaly sealed into first carrying body having opposed surfaces dimensionaly interrelated (d s and d o ) and pneumaticaly interconnected with sealed surface in first carrying body (ch s ) exposed to said gas supply pressure, d. bearing surfaces on said first and second bodies geometricaly located and frictionlessly supported by a gas film to oppose and balance forces frictionlessly transmitted from the floating pads through a gas film (h o ) to the said guide surface on the second body, Said geometric arrangements allowing frictionless movement perpendicular to said forces and in the direction of the bearing surfaces with the floating pad serving to maintain balanced relationship between bearing and guide surfaces and to compensate for limited dimensional variations.
Claim 3
Dependent Claim 26 words
A system according to claim 1 and wherein said bodies are each disposed to having a planer geometric configuration so that their bearing motion is linear.
Claim 4
Dependent Claim 28 words
A system according to claim 1 and wherein said bodies are each disposed to having a geometric surface of revolution configuration so that their bearing motion is rotational.
Claim 5
Dependent Claim 33 words
A system according to claim 1 and wherein said bodies are each disposed to having a combined linear and rotational geometric configuration so that bearing motion is either linear or rotational or both.
