In this paper, the tooth contact pattern and transmission errors are analyzed using tooth contact analysis (TCA) in order to manufacture the worm gears with high precision. Before manufacturing worm gear set, profile errors of a worm hob cutter for tool are measured using a gear measuring machine and these measured results are fed back to TCA results in order to improve the accuracy of TCA. The setting of the hobbing machine for worm wheel manufacturing and the amounts of modification in profile and lead directions of worm grinding machine for worm are determined so that the expected meshing conditions can be obtained based on TCA results. The dual lead worm gears in ISO type I were designed and manufactured based on this method and the experimental tooth contact patterns and transmission errors were compared with analyzed ones. As a result, the validity of this method was confirmed.
