The worm gear is composed of two different components, one is the worm made by the screw shape cut on the shaft, and the other is a mating gear, namely a worm wheel. Both of these components on a non-intersecting shaft are called worm gear.

Worm gears are usually applied to large gear reductions, so they generally have reductions of 25:1 or higher. Worm gears ensure dependable, continuous, smooth and quiet running gearing under correct design.
