内齿轮成形磨削及砂轮修形技术的研究

针对国内硬齿面内齿轮普遍采用插(拉)齿后氮化处理而未磨齿的加工现状，研究了内齿轮成形磨削方法和砂轮修形技术。基于自主研制的数控内齿轮成形磨齿机，提出了一种使用砂轮的一个端面磨削轮齿两个齿面的加工方案。采用跳齿磨削法控制分齿精度。研制了一种成形砂轮修整装置，开发了成形砂轮修形程序。仿真结果验证了该程序的可行性。

Study on the Internal Gear Form Grinding and Wheel Dressing Technology

Aiming at the machining status that internal gears with hard face were processed generally by nitriding after gear shaping or broaching, a form grinding method of internal gear and a dressing technology of form grinding wheel were studied. Based on the autonomous developed CNC internal gear form grinding machine,a grinding plan was proposed by which two flanks of a tooth could be ground by using one end of
the grinding wheel.Jumping division was used to control the pitch error.A kind of form wheel dresser was developed，and form wheel dressing program was prepared.Simulation
results show that the dressing program is feasible.
