以斜齿轮为研究对象,应用最小弹性势能原理(MEPE)和弹性流体动力润滑理论(EHL),采用多重网格数值求解法获得了斜齿轮在不同啮合位置及沿接触线方向的载荷分布,压力与膜厚分布,并对比分析了不同螺旋角下基于MEPE理论和基于接触线长比例理论的载荷分布模型及数值仿真结果.结果表明:沿啮合线方向,载荷在啮合中间段达到最大值,螺旋角越大,载荷分布趋于平均;受综合曲率半径和载荷分布的影响,压力分布在啮合中间段较高,膜厚沿啮合线缓慢变化,节点处稍有下降;沿接触线方向,载荷变化平缓,近似呈抛物线,最小膜厚单向线性变化,而压力则在两端具有较大值.
Using helical gear as the research object, the load distribution of helical gears at different meshing positions and along the line of contact was obtained by using the multi-grid numerical solution method with the minimum elastic potential energy principle (MEPE) and the elastic fluid dynamic lubrication theory (EHL) And the film thickness distribution are compared and analyzed. The load distribution model and the numerical simulation results based on the MEPE theory and the theory of contact wire length and length under different helix angles are compared and analyzed. The results show that the load reaches the maximum value in the mid- The larger the angle, the more uniform the load distribution. Under the influence of the integrated radius of curvature and the load distribution, the pressure distribution is higher in the middle part of meshing, the film thickness changes slowly along the meshing line and decreases slightly at the node. Along the contact line, Flat, approximately parabolic, with minimal unidirectional linear change in film thickness, while pressure has a larger value at both ends.
