In recent years, high precision dual lead worm gears in JIS 4 type have been required. In this paper, the tooth contact pattern and transmission errors are set using tooth contact analysis in order to manufacture the worm gears with high precision. The dual lead worm gears in JIS 4 type 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.
