摘　　要：在分析一类高速气浮轴承工作原理的基础上 ,建立其轴径轴承的静态承载力模型 ,并据此分析出轴承间隙中气体流量、压强与节流孔孔径间的相互关系 ,以及在低速运转下受离心力作用的轴径中心运动轨迹。最后 ,通过模拟仿真并考虑实际工况给出了轴承间隙和节流孔孔径两个关键尺寸。Based on the analysis of one type high-speed gas bearing working principle, the bearing diameter of axle static carrying force model was set up, and the relationship between bearing clearance gas flow rate, intensity of pressure and orifice radius were analyzed, along with the diameter of axle movement tracking under the centrifugal force in the low rotating speed was found. At last the two key parameters of the bearing clearance and the orifice radius were given by simulation and consideration of the real working conditions. The researches provide a good base for Chinese domestic of high-speed gas bearing.
