Title:
STATIC PRESSURE GAS BEARING DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/016275
Kind Code:
A1
Abstract:
The present invention provides a static pressure gas bearing device that is suitable for supporting a large supported object without contact. A plurality of accommodating holes (211) for accommodating static pressure gas bearings (10) are provided in a surface (212) of a top plate (21) of a static pressure gas bearing device (1), the static pressure gas bearings (10) being accommodated in each of the accommodating holes (211) so that bearing faces (13) of the static pressure gas bearings (10) (surfaces (111) of porous metal sintered members (11)) and the surface (212) of the top plate (21) are aligned. A compressed gas film is formed between the surface (212) of the top plate (21) and the plate-shaped supported object disposed on the surface (212), whereby the entirety of the surface (212) of the top plate (21), including the bearing faces (13) of the static pressure gas bearings (10), functions as a bearing surface supporting the supported object without contact.
