花键孔零件磨齿精度保证的工艺研究

Research on Grinding Precision of Spline Hole Parts

以内孔为花键孔、非对称结构的异形齿轮件为研究对象,通过变形分析,设计热处理补偿套、花键心轴,优化了热后加工工艺,完成了异形内花键齿轮件磨齿试验加工,满足了产品图纸的设计要求。同时,探索了一种新的工艺加工方法,达到成本最优的目的。

The research object of this paper is the non-symmetric special-shaped gear with spline bore.Through deformation analysis,the heat treatment compensation sleeve and spline mandrel are designed,and the hot post processing technology is optimized.The grinding experiment of special-shaped inner spline gear is completed,which meets the design requirements of product drawings.At the same time,a new processing method is explored to achieve the goal of cost optimization.
