Title:

STATIC PRESSURE GAS BEARING DEVICE

Document Type and Number:

Japanese Patent JPS5868516

Kind Code:

A

Abstract:

PURPOSE:To keep the bearing part from the intrusion of machining liquid and chips by a method wherein the pressured gas is exhausted to the wheel side through the clearance between the rotating shaft and the corresponding parts, in the titled bearing deice of the machine which cuts the metal scrap, etc. by the wheel. CONSTITUTION:The rotating shaft 57 is floatingly supported by the radial bearing reduced parts 51-54 into which the pressure gas is introduced, and the same structure thrust bearing reduced parts 55, 56. The rotating shaft 57 is driven at high speed by the high frequency motors 61, 62 provided at the one end of the shaft. Further, the pushing flange 58 which fixes the wheel 59 to process the work part, and the cover 60 are provided at the other end of the rotating shaft 57. Thereby, the partial pressured gas is exhausted to the wheel 59 side through the clearance between the rotating shaft 57 and the both thrust plate 64 and the cover base 65. The remaining gas is collected into the exhaust hole 63, and is led through the clearance between the motor 61 and 62, then is exhausted to the outside through the outlet 66 after cooling the motor.
