GAS BEARING, BEARING DEVICE, COMPRESSOR, AND METHOD OF CONTROLLING BEHAVIOR OF GAS BEARING

摘要

PROBLEM TO BE SOLVED: To provide a gas bearing capable of satisfactorily supporting a rotating shaft while minimizing a bearing diameter, a bearing device using the gas bearing, a compressor, and a method of controlling the behavior of the gas bearing. SOLUTION: The compressor is formed to support the rotating shaft 3 on a casing through the gas bearing 11 in the state of allowing the rotation about the axis thereof. The gas bearing 11 comprises a bearing body 12 into which the rotating shaft 3 is inserted. A discharge port discharging a working gas in the bearing body 12 to the outside is formed at the upper part of the bearing body 12. COPYRIGHT: (C)2005,JPO&NCIPI
