摘　　要：根据轴承表面对液体分子的作用大于液体内部的作用 ,使液体的粘度随与表面的距离而变化 ,把润滑层简化为三层 ,与表面紧邻为粘变层 ,中间为常规的等粘度层。由此根据液流连续性推导出计算径向轴承的广义雷诺方程 。Based on the fact that the interaction between bearing surfaces and liquid molecules is greater than action into liquid, lubrication layer will be simplified as three layers, because the viscosity of liquid varies as distance which is from bearing surface to liquid The layer near surface is known as viscosity changing layer, the middle as conventional isoviscous layer Therefore, the general Reynolds equation for journal bearing calculated is derived based on continuity of liquid flow And the analysis and calculation of bearing characteristics are made
