Description

technical field

[0001] The invention relates to the technical field of static pressure gas thrust bearings, in particular to a static pressure gas thrust bearing with adjustable throttling effect. Background technique

[0002] Due to the advantages of high precision, hydrostatic gas thrust bearings are widely used in precision machine tools and precision measuring equipment. The stiffness characteristics of hydrostatic gas thrust bearings are the key to ensuring the high-precision performance of precision machine tools and precision measuring equipment. Therefore, improving the stiffness of aerostatic bearings is the key to improving the performance of precision machine tools and precision measuring equipment. Through the throttling effect of the restrictor, the static pressure gas thrust bearing makes the pressure in the air film gap change with the change of the air film gap, thereby generating stiffness. Generally, the better the throttling effect of the throttle, the g...
