针对直齿轮多工况使用情况,研究了小轮修形齿面理论建模方法和直齿轮传动多工况多目标修形优化方法,进行了两种工况下直齿轮传动多工况多目标修形优化设计,并进行了修形和不修形齿轮的齿面啮合仿真,通过对比分析,验证了齿面优化修形后达到了较好的综合性能,两种工况下的承载传动误差波动幅值和最大闪温均明显下降。研究成果为提高直齿轮综合性能的修形设计奠定了基础。

Considering that spur gears are used under multiple-condition,the modeling method of modified tooth surface for pinion and the multi-condition and multi-objective modification optimization methods of the spur gear transmission are researched.The multi-condition and multi-objective modification optimization design of spur gear transmission under two working conditions is carried out,and the modification optimum design and unmodified tooth surface meshing simulation of a spur gear transmission system are carried out.It is verified by comparison that the spur gear transmission with modification optimization have good comprehensive performance,and its fluctuation amplitude of loaded transmission error as well as maximum flash temperature decrease obviously in both situation.The research results lay a foundation for modification design to improve the comprehensive performance of spur gears.
