The roller worm gear drives have been widely adopted in numerous industrial applications such as robot joint reducer, heavy-duty production line. This study is to improve the performance of a roller gear drive by utilizing an iterative optimization scheme to improve the tooth profile of the hourglass worm gear in the roller gear drive. Dedicated design of the variable-pitch slot on the hourglass worm gear can remedy the power efficiency of the roller gear drive by enhancing the contact ratio dramatically. This research showed that the roller gear drive is a better mechanism for the high reduction ratio reducers. The CAD design and performance analysis of a roller gear drive by SolidWorks have provided the engineers an optimizing methodology.
