摘　　要：文章从对重型牵引汽车电动轮减速装置优化角度出发,分析减速装置的载荷条件以及工作状况等因素,将NGW行星齿轮减速器的体积、效率以及齿轮重合度作为目标函数,根据可靠性理论对减速装置进行优化设计。通过把齿轮的轮齿齿面接触疲劳强度与齿根弯曲疲劳强度的校核结合可靠性理论使用到优化设计中的约束条件中,计算减速装置零部件参数的最优解,使得在质量最轻、体积最小的同时传动效率依旧可靠。通过一系列的优化设计,使得减速装置可以满足牵引汽车电动轮模块的特殊要求,也为今后重型牵引汽车电动化设计以及相关研究提供一定的参考依据,助力创建绿色、节能、低碳、环保的现代交通运输体系。Based on the optimization of electric gear reduction device for heavy tractor,this paper analyzes the load conditions and working conditions of gear reduction device,takes the volume,efficiency and gear overlap degree of NGW planetary gear reduction device as the objective function,and optimizes the design of gear reduction device according to the reliability theory.Combining the reliability theory and the checking of the contact fatigue strength of the tooth surface and the bending fatigue strength of the tooth root into the constraint conditions of the optimization design,it calculates the optimal solution of the parameters of the reducer parts,which makes the transmission efficiency reliable with the lightest mass and the smallest volume.Through a series of optimization design,the reduction device not only meet the special requirements of traction vehicle electric wheel module,but provide a certain reference basis for the future heavy traction vehicle electric design and related research,to effectively create a green,energy-saving,low-carbon,environmental protection of the modern transportation system.
