To reduce the edge contact of gear tooth surface on load, a new concept has been proposed for designing worm gears, and has been adopted to the worm gears having small lead angles. In this research, this concept is adopted in designing hourglass worm gears with large lead angles. Prior to the actual design, the worm axis displacement relative to the wheel axis is roughly estimated by means of the elastic deformation theory. And, this idea is applied to the gear designs using two kinds of hourglass worm gears with large lead angles. Numerical analyses indicate that as much as 70% of the theoretical area of the utilized worm gear contributes to meshing at their estimated displacement positions. As a result, the validity of this design concept was also proven in the case of worm gears with large lead angles.
