    Judging from manufacturing errors and deflections under load, worm gears do not operate in their ideal relative positions. It is important to predict the load distribution considering tooth profile and setting error. A method for determining the load distribution, Hertzian contact pressure and oil film thickness is presented in this paper. Using our empirical formula for bending deflections, we developed the matrix of transformation. The deflection along the load direction on any point of a contact line at the same meshing position is expressed by the matrix of transformation. Using this matrix, the load distribution of a worm and wheel is evaluated with numerical analysis. It is obvious that the calculated results agree comparatively with experimental ones under actual operating conditions. With this calculating method, the effects of various types of misalignment on tooth contact are clarified.
