摘　　要：利用局部综合法对非零正传动弧齿锥齿轮副进行大重合度加工参数设计,克服了非零正传动由于啮合角增大而使得重合度降低的不足。通过实例与常规设计的结果进行仿真与应力分析对比,结果表明,在同样的载荷条件下,新设计比常规设计的小轮最大齿根拉伸应力减小27.6%,最大齿根压缩应力减小23.5%,最大齿面接触应力减小6.5%,同时大轮的齿根应力也有所降低,使得齿轮副具有更高的寿命和可靠性。For non-zero-modification transmission spiral bevel gear, its machining parameters can be designed with local synthesis. This new design method can correct the shortage of non-zero- positive transmission, because it lets contact ratio decline with mesh angle increasing. Two different designs about stress analysis were compared by using an example. With the same load, the new design made pinion root stress reduced obviously then traditional design, the maximal root stretched stress reduced 27.6%, the maximal root compressed stress reduced 23.5%, the maximal tooth contact stress reduced 6.5 %, and gear root stress also reduced a little. New tooth profile and machining parameters design prolonged the gear set life and higher its reliability.
