摘　　要：分析影响薄壁主动齿轮性能的主要因素,提出提高薄壁主动齿轮性能的制造工艺方案,即严格卡控关键制造工序,从原材料、热处理、强化喷丸、提高齿根粗糙度和降低组装过盈量等方面来提高齿轮的疲劳强度和运行寿命。Through the analysis of influence factors of mechanical performance of driving pinion, some new manufacture technologies were put forward. That is to say, the key produce programs should be striekly controlled. The material, heat treatment, shot peening, roughness and assembly technology etc. , those faetors can improve the fatigue strength of driving pinion. So the life of the pinion can be prolonged largely.

关 键 词：薄壁主动齿轮 残余压应力 强化喷丸 热处理
