Vortex type air outlet plane static pressure air bearing

The invention discloses a plane static pressure air bearing structure with vortex type air outlet. According to the plane static pressure gas bearing structure, a novel vortex generation structure is adopted to replace traditional small hole throttling, the throttling mode that high-pressure gas flows out of a throttling hole in the mode of being perpendicular to a guide rail is changed, and sudden changes of the speed and the direction after the high-pressure gas impacts the guide rail can be effectively restrained. The micro-vibration of the air bearing during working is reduced, and the comprehensive performance of the air bearing is improved. 本发明公开了一种涡旋型出气的平面静压气浮轴承结构。本发明的平面静压气浮轴承结构采用一种新型涡旋发生结构代替传统的小孔节流，改变了高压气体垂直于导轨流出节流孔的节流方式，可以有效抑制高压气体撞击导轨后速度大小和方向产生的突变。本发明降低了气浮轴承工作时的微振动，提高了气浮轴承综合性能。
