摘要

针对采煤机摇臂齿轮传动系统的设计,以可靠性设计理论为基础,推导出在齿轮强度、应力都服从正态分布时的齿面接触疲劳强度和齿根弯曲疲劳强度为约束条件,齿轮系体积最小为目标函数的优化数学模型,通过Matlab的遗传算法优化工具箱对其进行优化求解。实例结果表明,方法得到的设计参数能有效地提高摇臂齿轮传动系统的可靠度,减小齿轮传动系统的体积、重量,有利于实现产品轻量化,节约成本。

Abstract

In the process of design shearer ’s ranging arm gear transmission system,by using the method of reliability design theory,derived gear strength and stress assumed to obey normal distribution when tooth surface contact fatigue strength and tooth root bending fatigue strength were taken as constraint conditions,and the volume of gear system as objective function,then genetic algorithm optimization toolbox of MATLAB was used to solve the optimization mathematic model. The results show that this method of optimization can improve gear transmission’s reliability,the volume and weight of gear transmission system are reduced too,which is beneficial to achieving products lightweight and reduceing production cost.
