Plastic Worm Gears



These plastic gears are lighter and quieter than metal gears—pair them with metal worms for lubrication-free operation. 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 module.
Speed ratio is the ratio by which output shaft speed is reduced. As speed decreases, torque increases.
Nylon gears are lightweight and stronger than acetal gears.
