摘　　要：对可逆轧机换向过程中轴承最小油膜厚度随时间的变化规律进行了理论分析。用有限差分法，将普遍Ｒｅｙｎｏｌｄｓ方程、轴瓦巴氏合金层的弹性变形方程用于可逆轧机轴承的设计计算，建立了非稳态轴承在低速重载条件下的数学模型。The theoretical analysis of the relationship between minimum oil film thickness of journal bearing and time has been done during the reversible rolling mill changes its running direction. A finite difference method is used to solve the Reynolds(using for unstatic-load journal bearing)、elasticity equation to calculate the bearing of reversible rolling mill. The mathematical model of the hydrodynamic oil lubricated journal bearing under low speed heavy load working condition is established.
