By dealing with the load data from vehicle test on typical terrain, this paper obtains the torque and stress spectrum bearing by the side reducer gear in armored vehicle. Considering the influence of the residual stress on the contacting fatigue limit, the distribution of strength and contacting fatigue limits in different depths were obtained by means of the distribution of residual stress and hardness as well as the relationship between strength and hardness. The gear＇s fatigue life was predicted by combining the fatigue life prediction technique. The prediction result is accorded with the actual rule.
