广泛应用的美国 Gleason 公司准双曲面齿轮变性半展成切齿调整计算法(简称 HFM法),为简化计算,把小轮切齿计算参考点 P 选在分度锥面上齿圈中点处,与所要求的齿面接触区中心对应点 M 不重合。由于理论上存在误差,切齿时不得不按接触印痕进行附加调整。根据文献[4]的原理,本文以接触区中心 M 为小轮切齿调整计算参考点,对Gleason 公司的 HFM 法进行了改造,克服了这种方法中所存在的缺点。作为本文所提 Widely used in the United States Gleason hypoid gear semi-degeneration into a cutter adjustment method (HFM method), in order to simplify the calculation, the chevron gear selection reference point P is selected at the midpoint of the indexing cone gear ring, and The required center point of the tooth contact area M does not coincide. Due to the theoretical error, incisors had to make additional adjustments according to the contact impression. According to the principle of literature [4], this paper reconstructed the Gleason HFM method by taking the contact center M as the reference point for the adjustment of the cogwheel cutting teeth, which overcomes the shortcomings of this method.
