Multi-objectve Optimization Design of Differential Gear with Few Tooth Based on Fuzzy Algorithm

基于优化设计模糊算法的基本理论,研究少齿差行星减速器的运行状态及相关工况条件,针对少齿差齿轮副的传动特性,建立少齿差行星轮减速器的数学模型,通过确立齿轮体积和重合度的目标函数,优化少齿差行星轮的几何参数,并与常规设计相比,少齿差行星传动的体积和重合度都得到优化。

Based on the basic theory of optimization design of fuzzy algorithm, this paper mainly researches the running state of fewer teeth difference planetary gears reducer and its relevant working conditions. Taking advantage of the transmission characteristic of gear pair with small teeth difference, the authors built a mathematical model of planetary gear reducer and optimized the geometric parameters of few-tooth- difference planetary wheel by establishing the objective function of gear size and contact ratio. Besides, af- ter comparing the results obtained from the normal design with the results of optimization design of fuzzy algorithm, the authors find that both gear size and contact ratio of fewer teeth difference planetary trans- mission were optimized.
