改写优化后一挡齿轮重合度提高了15二挡齿轮重合度由提高了11主减速器齿轮的重合度提高了18提高幅度都比较明显而且优化后的齿轮轴向重合度都在18左右端面重合度大于1且非常接近1降低了齿面载荷变化幅度使传动更加稳定噪声更小

The optimization has resulted in a 15% improvement in the meshing accuracy of the first gear, an 11% improvement in the meshing accuracy of the second gear, and an 18% improvement in the meshing accuracy of the main reducer gear. These improvements are quite significant, and the optimized gear axials are all around 1.8, with end face overlap greater than 1 and very close to 1. This has reduced the variation in tooth surface load and made the transmission more stable and less noisy.
