Research on Gear Modification Optimization Design of Dual Power Drive Gearbox

以某型双动力驱动齿轮箱为研究对象,通过静力学仿真,分析了动力源A输入端齿轮副的传动误差及齿面载荷;根据齿轮副修形方法,利用Romax软件,开展了修形参数对传动误差、齿面载荷的影响规律研究;以此为基础,通过遗传算法,开展了齿廓修形与螺旋线修形相结合的齿轮综合修形优化设计,并对修形前后的齿轮副进行了对比分析。结果表明,修形后齿轮传动误差明显减小,且齿面载荷分布更加均匀。

Taking a certain type of dual-power drive gearbox transmission system as the research object,through static simulation,the transmission error and tooth surface load of the gear pair at the input end of the power source A are analyzed.According to the gear pair modification method,the Romax software is used to car⁃ry out the research on the influence law of the modification parameters in the transmission error and tooth sur⁃face load.Based on this,through genetic algorithm,the gear comprehensive modification optimization design combining tooth profile modification and helical modification is carried out,and the gear pair before and after modification is compared and analyzed.The results show that the gear transmission error is obviously reduced af⁃ter the modification,and the tooth surface load distribution is more uniform.
