PURPOSE: To heighten the rigidity of a bearing by furnishing a stator with cavities distributing periodically facing a support surface on a rotor, supplying a pressure gas to the cavities, and installing an air-tight device to admit runoff of a certain quantity of gas on each side of a bearing set between the stator and the shaft of rotor. CONSTITUTION: A stator is furnished with cavities 3 distributing periodically facing a support surface provided on a rotor 7. From an orifice 4, a pressure gas is supplied to the cavities 3. An air-tight device 12 to admit runoff of a certain quantity of gas is installed on each side of a bearing set between the stator and the shaft of the rotor 7. This allows maintaining the output pressures of a radial bearing 10 and axial bearing 11. As a result, the rigidity of the bearings can be heightened to a great extent, and the field of application as a gas bearing can be widened. |
