| Abstract: | For the gear with low safety factor on the input shaft of a new energy vehicle, shot peening was applied on.At the same time, the roughness of the tooth surface after shot peening and the residual stress in the specified position were tested.The input shaft stress after shot peening is qualified and meets the durability test demand of the vehicle. It is confirmed that reasonable shot peening can effectively improve the residual stress and improve its bending and contact safety coefficient. |
