Abstract Face gear drives have been widely applied in power transmission, but the finishing of continuous generation is a difficult problem. This is mainly because the teeth of face gears are on a plane, which leads to interference by worm grinding. Hence, a shaving method for face gears is proposed in this paper. This work studies the theory of face gear shaving, the causes of mid-concave phenomena based on load tooth contact analysis (LTCA), a solution for the modification coefficient of the shaving cutter and a control method for the cutter location point. The experimental results show that the maximum machining error is − 12.7 μ m , that many generating lines appear and that the residual stress increases by 49.2% in comparison with that of the grinding tooth surface. The present study suggests that the shaving method for spur face gears can not only achieve the finishing of continuous generation but also improve the surface integrity of the gear.

一种用剃齿刀连续生成直齿面齿轮的精加工方法

摘要 平面齿轮传动在动力传动中得到了广泛的应用，但连续发电的精加工是一个难题。这主要是因为平面齿轮的齿在一个平面上，导致蜗杆磨削产生干涉。因此，本文提出了一种平面齿轮的剃齿方法。这项工作研究了平面齿轮剃齿的理论，基于负载齿接触分析（LTCA）的中凹现象的成因，剃齿刀修正系数的解决方案和刀具定位点的控制方法。实验结果表明，最大加工误差为−12.7 μm，出现多条母线，残余应力较磨齿面增加49.2%。
