采煤机销轨轮强度分析及齿形优化设计（英文）

基于齿轮啮合原理,利用坐标变换方程推导出销轨轮与销排啮合的齿廓方程,根据齿廓方程构建销轨轮的实体模型,并利用有限元软件ANSYS计算出齿轮根部的弯曲应力,找出销轨轮齿廓的应力敏感部位。应用ANSYS中的优化设计功能,以销轨轮齿根部弯曲应力最小为目标,对两组不同设计变量下的目标函数进行优化设计,获得了销轨轮最佳齿廓形状和齿形参数。

Strength analysis and tooth shape optimization design of the pin rail wheel of the shearer

Based on the principle of gear meshing,the tooth profile equation of the meshing side of the pin rail wheel and the pin row is derived by using the coordinate transformation equation.The solid model of the pin rail wheel is established on the basis of the tooth profile equation,the bending stress of the root of the gear is calculated by the finite element software ANSYS,and the stress sensitive part of the tooth profile of the pin rail wheel was found.Applying the optimization design function of ANSYS,the objective function of two groups of different design variables is optimized in order to minimize the bending stress of tooth root of pin rail wheel,and the optimal tooth profile and tooth profile parameters of pin rail are obtained,respectively.The obtained conclusions can provide theoretical basis for further system research of pin rail wheel,and has a certain practical significance.
