摘　　要：等高齿作为汽车主减速器的重要零部件之一,其畸变一致性直接影响着齿轮接触区一致性的好坏。为了有利于等高齿热处理畸变一致性的控制,研究了其在不同装炉方式下的齿轮热处理畸变情况。研究表明,边缘位置的主动齿轮畸变量稍大于中心位置;主被动齿轮底层位置畸变一致性明显低于上层和中层位置;稀疏装炉齿轮畸变一致性明显低于密集装炉。同时,改进了被动齿轮装炉料架,为优化热处理工装和提高等高齿热处理畸变一致性提供了依据,对齿轮热处理畸变一致性提高方面提出了一些参考意见。The constant-depth tooth hypoid gear is one of the important parts of the main reducer. The distortion of consistency directly affects the consistency of the gear contact area. In order to facilitate the con trol of the consistency of the heat treatment distortion of the constant-depth tooth,the gear heat treatment dis tortion under different furnace loading methods is studied. The study shows that the distortion of the main teeth at the edge position is slightly larger than the center;the deformation of the main bottom layer is signifi cantly lower than that of the upper and middle layers;the deformation consistency of the sparse charging gear is significantly lower than that of the intensive loading furnace. At the same time, the tooth mounted charge frame is improved, the basis for the optimization of heat treatment fixture and improve the gear heat treatment distortion consistency is provided, some suggestions on improving the heat treatment distortion consistency of the gear are put forward.
