摘　　要：采用Грубин提出的弹流润滑入口区分析方法,计算得到渐开线齿轮的整个啮合过程中心油膜厚度的变化趋势。轮齿的啮合变形量的求解基于Weber能量法的理论,给出了详细的计算公式;由于中心油膜厚度的计算基于Грубин的入口区分析方法,Hertz理论在接触变形的求解中仍然成立,且采用Weber推导的近似公式计算。求出中心油膜厚度和啮合变形量后,根据刚度的定义式得到等效啮合刚度。同时进一步分析了不同转速和不同变位系数下的啮合刚度的变化,根据它们的变化趋势,可以更好的为传动系统的平稳提供理论依据。The method of analyzing the elasto-hydrodynamic lubrication in inlet zone which presented by Fpy6Hn /s used to calculate the central oil film thickness value during the whole meshing process. The gear tooth compliance is solved by using the compliance farmula on the basis of Weber energy method. Because of using the Грубин＇s inlet zone analysis method, the Hertz theory in solving the local compliance is still established,and use the expression developed by Weber is calculated. After getting the results of central oil film thickness and gear tooth compliance, the equivalent mesh stiffness can be got. The further research of mesh stiffness in different rotational rate and addendum modification coefficient is given. A nd these results are good guidance for the transmission system＇s stationeriness.
