摘要: 针对螺旋锥齿轮倒棱大小无法精确控制的问题,提出了一种采用锥形刀具进行齿顶倒棱加工的方法.该方法建立了齿顶棱线方程,并以此为依据推导出刀具轨迹方程;根据锥形刀具的锥角和倒棱的长度,经过几何变换计算出刀尖点位置和刀轴矢量;在此基础上确定刀具加工轨迹进而完成齿顶倒棱加工.仿真结果表明,在3组不同倒棱参数下,倒棱的形状误差≤ 0.05 mm,提高了倒棱精度,且可灵活控制倒棱大小.Abstract: In order to solve the problem that the chamfer size of spiral bevel gears cannot be precisely controlled,a method for chamfering the tooth top with a conical cutter was proposed.This method established the tooth crest equation, and derived the tool path equation based on this. According to the taper angle of the conical cutter and the length of the chamfer, the position of the tool tip point and the tool axis vector could be calculated through geometric transformation.From this, the machining path of the tool was determined to complete the chamfering of tooth top. Simulation results showed that under three different chamfer parameters, the chamfer shape error was not more than 0.05 mm, which improved the chamfer accuracy, and could flexibly control the chamfer size.
