摘要
针对采煤机截割部太阳轮花键轴进行理论计算和有限元分析,从而找出发生失效变形的原因,并提出增加花键轴的直径和花键齿数,改变热处理工艺的方案。实践证明:改进后的太阳轮花键轴强度和性能能够满足工况要求。
To oretical calculation and finite element analysis in view of the spline-shaft for cutting part of sun wheel of shearer, so as to find out the causes of the failure and deformation,and put forward the way of increasing the spline shaft diameter and the spline tooth number and changing the heat treatment proess. The practice proved that： the improved strength of spline shaft of the sun wheel can meet the requirements of working conditions.
