摘要
分析了三圆弧瓦精密轴系轴瓦的结构形式及其几何关系，建立了有关的几何方程和计算公式。根据雷诺方程，通过数值计算，求出了轴瓦分布角改变时相应轴承结构油膜的动压变化规律及其润滑的一些静态特性，计算结果可作为精密轴系结构设计和参数确定的依据。
The structure design and geometry of pads of precision three pad hydrodynamic journalbearings are analyzed,and their relevant geometry equations and calculating formulas are deviced.In the light of Reynold’s equation, hydrodynamic regularity and some lubricant staticcharacteristics of fluid film of the bearings which depends on the distribution angle of padsare obtained by means of numerical calculating method.Comptited results can be used as datafor structure design and parameter determining of the precision bearings.
