在不改动矿车行星齿轮减速机构安装尺寸的前提下,以齿轮齿数及变位系数作为优化变量,以提高齿轮接触应力安全系数为目的,通过对离散变量的序列化处理,采用复合形法优化了行星齿轮机构的设计参数。此种优化算法流程简单,实用性强,优化后的接触应力大幅降低,可以显著提高齿轮的耐磨性与使用寿命。 Under the premise of not changing the installation size of the planetary gear reducer, the gear tooth number and displacement coefficient are taken as the optimization variables to improve the contact stress safety factor of the gear. Through the serialization of discrete variables, The design parameters of the planetary gear mechanism. This kind of optimization algorithm has the advantages of simple procedure, strong practicability, greatly reduced contact stress after optimization, and significantly improved wear resistance and service life of gears.
