A Predicting method of tooth root stress of hypoid gears is proposed. The deformation of tooth and rim of hypoid gears calculated by FEA is compared with that of cylindrical involute gears, and the approximation equation for the compliance of cylindrical involute gear tooth is modified to that of hypoid gear tooth. Then considering the FEA calculated tooth root stress of hypoid gears, the approximation equation of tooth root stress for hypoid gears is derived by modifying the approximation equation of cylindrical involute gears. The contact pattern, normal load and tooth root stress of a hypoid gear set for 3 different patterns of tooth flank contact marking are calculated by the prediction method proposed in this paper. It is shown that the tooth root stress calculated by the proposed method matches well with the value calculated by FEA.
