摘　　要：法向圆弧锥齿轮是基于Bertrand共轭原理发展起来的一种新型传动形式,研究内容旨在对该种齿轮的加工进一步完善;以曲率轴为手段研究了该种齿轮采用盘状环面铣刀和指状环面铣刀加工时的干涉问题,通过分析刀具轴线的位置和刀具半径的影响,给出了不发生曲率干涉时应满足的条件;研究结果表明,采用指状环面铣刀加工时一定不会发生曲率干涉,盘铣刀加工时不发生干涉的条件与刀盘直径的最大值有关;研究结果对完善该齿轮的加工工艺具有重要意义.Normal circular-arc bevel gear pair is a new type of transmission pair based on Bertrand conjugation principle. The present research is focused on improving the machining technology further. The intervention was studied by means of curvature axis. Through analyzing the influence of the cutter radius and the location of tool axis, the conditions without intervention were given. The result shows that curvature intervention will not happen when machining with finger-ring cutter, and the conditions without intervention are related to the maximum of cutter diameter when machining with discoid torus cutter. The present research has great significance in improving the machining technology of gear.
