A load distribution model along the line of contact considering sliding friction is proposed for both spur and helical gear pairs in order to determine the critical load condition. Further, a semi-analytical method is introduced for modeling the stress field of coated gears. The elastic field is calculated by utilizing influence coefficients obtained from frequency response functions and discrete convolution and fast Fourier transform. Effects of friction coefficient, coating properties and thickness on the stress distribution of a gear pair at the critical load position during meshing are investigated. Maps describing the maximum transverse and shear stress distributions on coating–substrate interface with respect to friction coefficient and coating thickness are demonstrated, which may facilitate the selection of preferable coating thickness.
