More Information
Summary:The present invention relates to a 'bicharacteristics combined throttle static pressure gas conical bearing', it is a high-rigidity large-load ultraprecision static pressure gas conical bearing. It is characterized by that on the conical bearing working surface, at two sides of static pressure gas-float gas-supplying point distributed circle cutting cheveron hydrodynamic grooves; under the condition of that the gas consumption of gas-float bearing is not increased, as compared with traditional static pressure gas-float conical bearing its bearing loading capacity can be raised by above 30%, and its bearing rigidity can be raised by above 15%.
