scope:

The authors have developed a computerized method for simulation of meshing and bearing contact (TCA) for single-enveloping worm-gear drives. The developed computer programs enable to determine the transmission errors and the shift of bearing contact that are caused by worm and gear misalignment. An important theorem is proven for determination of the transfer point on the theoretical line of contact where the path of point contact starts for a misaligned worm-gear drive. A method of assembly for compensation of misalignment is proposed.
