摘　　要：建立了重载齿轮传动的弹流润滑模型,采用多重网格、多重网格积分以及逐列扫描法,计算出压力、膜厚以及次表面剪应力等。结果表明:润滑油黏度和齿面综合速度同时改变时,随着润滑油黏度和齿面综合速度乘积的增大,平均膜厚单调增大,而次表面剪应力单调减小。载荷越大,次表面剪应力最大值的X坐标位置越靠近出油口的位置。A model was set up to analyze the elastohydrodynamic lubrication of the cylindrical gear transmission, using the theory of fourier nonlinear regression, regression conforms to the shape of real tooth surface roughness equations. The numerical calculation of the numerical solution were calculated respectively by the multi-grid method ,the multi-integration method and the column scanning method. The results show that with an increment of the lubricating oil viscosity and tooth surface speed, the average film thickness increases and surface shear stress monotonically decreases at the same time. The larger the load, the greater X coordinates of the maximum surface shear stress near the position of oil outlet in the premise of lubricating viscosity and tooth surface velocity change at the same time.
