This paper gives some ideas how to calculate tooth load distribution of one pair of mating gears with assembly errors. The main procedures are as follows. Firstly contact points surrounding the geometrical contact line on the tooth face of one gear are assumed. Secondly position changes of these contact points under a proposed special three-dimensional coordinate system are calculated by using three-dimensional coordinate transforming method when the gear shaft has assembly errors. Thirdly points on the tooth face of the other gear of the mating gears which to be considered to contact with the contact points on the region of the former gear are looked for through a so-called section method suggested in this paper. Finally clearances and influence coefficient of these pairs of contact points are calculated by the three-dimensional finite element method and tooth load distribution on these pairs of contact points is calculated by the mathematical programming method. The calculated tooth root strains and tooth contact pattern are well agreed with the measured ones.
