Title:
HYDROSTATIC BEARING
Document Type and Number:
WIPO Patent Application WO/2016/129092
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a hydrostatic bearing (100, 200, 300) for which generation of unstable vibrations is limited. Said hydrostatic bearing (100, 200, 300) is provided with a cylindrical bearing member in which multiple through holes (110, 210, 310) are disposed at different positions in the circumferential direction and into which a rotating shaft (2) can be inserted. The hydrostatic bearing (100, 200, 300) is configured so that a previously pressurized lubricating fluid (20) is supplied to the through holes (110, 210, 310), the rotating shaft (2) is supported to rotate freely by the static pressure of the lubricating fluid (20), and bearing rigidity is anisotropic.
