在 Y 54插齿机上加工JD 11-4型调度绞车上用的大内齿轮一直是我厂的一个技术难题。这是因为该大内齿轮零件的外径是φ600mm,超过了 Y 54插齿机所能加工的最大工件直径 φ 462 mm。又由于在插齿过程中,存在着严重的偏载冲击负荷,使刀轴有明显的让刀现象,还有严重的噪声,加工出来 It is a technical problem of our factory to process the large internal gear used on the JD 54 ED-4 winch on the Y 54 gear shaper. This is because the outer diameter of the large internal gear part is φ600 mm, which exceeds the maximum work diameter φ 462 mm that can be machined by the Y 54 gear shaper. And because in the process of gear insertion, there is a serious partial load shock load, so that there is a clear blade cutter knife phenomenon, there are serious noise, processed out
