Based on the synthetic analysis of the finite element method of contact problems and its applications in gear transmission, this paper studies the boundary conditions on contact surfaces and presents an improved mixed finite element method for three-dimension contact problems with friction. Combined with the pre/post processing techniques of finite element models for the gear teeth,this method is used in the stress and strain analysis of the gear teeth satisfactorily. It is showed that this method is efficient and reliable for the study of the strength of gearing transmission.
