摘　　要：为了解决混合动力变速箱齿轮副在实际工作过程中出现的偏载现象,针对某混合动力轻卡变速箱减速齿轮副出现的齿轮偏载问题,通过齿轮分析软件Romax对啮合的斜齿轮进行三维建模,在运行设定的混合动力变速箱常用工况下对其中一对齿轮副进行仿真分析,并使用二代遗传算法进行了齿轮修形。修形结果表明,在不同工况下齿轮副的传动误差值、齿面接触载荷以及最大接触应力均有所减小,齿面偏载情况得到改善;齿轮啮合性能以及寿命得到了提高。研究为混合动力变速箱齿轮修形提供了理论参考。To deal with the phenomenon of partial load of the hybrid transmission gear pair in the actual working process and to solve the eccentric load problems of a hybrid light transmission gear pair,the gear analysis software Romax is used for 3D modeling of the meshing helical gears;one gear pair is simulated and analyzed under the commonly used operating conditions of the hybrid transmission set for operation,and the second-generation genetic algorithm is used for gear modification.The modification results show that the transmission error value,contact load and maximum contact stress of the gear pair are reduced under different working conditions,the offset load of the gear face is improved,and the meshing performance and life of the gear pair are improved,which provides some reference for the modification of the hybrid transmission gear.
