Single Start Worm

Raydafon, Single Start, Ground Worm Shafts Specifications

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.

Speed ratio is the ratio by which output shaft speed is reduced. As speed decreases, torque increases.

Bronze gears have low friction and dissipate heat better than iron gears to provide a long service life for both the gear and the worm.
