Worm Gears | McMaster-Carr

Worm gears use screw threads to make large reductions to shaft speed while transmitting motion at a right angle. They transmit motion from worm to gear and cannot be reversed. For gears and worms to mesh correctly, they must have the same pressure angle and pitch/module. These worms are compatible with plastic worm gears.. Speed ratio is the ratio by which output shaft speed is reduced.
