摘　　要：为了降低标准齿面人字齿轮在传动过程中的振动和噪音,提高传动系统的稳定性,需要对标准齿面人字齿轮采用修形来改善齿轮的啮合状态。首先采用蒙特卡洛法和遗传算法两种算法,对标准齿面小齿轮进行拓扑修形,修形曲线选择二次抛物线,然后分别对修形后的齿轮进行五种工况下加载分析,最后得到传动误差峰峰值图和接触应力分布图。结果表明:采用两种算法修形均降低了齿轮传动误差峰峰值和接触应力最大值并改善了齿面的接触应力分布,其中采用遗传算法修形的效果更显著。In order to reduce the vibration and noise of the standard tooth face herringbone gear in the transmission process and improve the stability of the transmission system,it is necessary to adopt modification to improve the meshing state of the standard tooth face herringbone gear.Monte Carlo method and genetic algorithm are used to modify the topology of standard tooth pinion,and the quadratic parabola is selected for the modification curve.Finally,the transmission error peak and contact stress distribu⁃tion are obtained.The results show that both algorithms reduce the peak value of gear transmission error and the maximum con⁃tact stress and improve the contact stress distribution of tooth surface.
