Spur Gears and Racks

Spur Gears and Racks

The simplest type of gear for transferring motion, with straight, parallel teeth

Worm Gears

Reduce speed while transferring motion at a right angle in only one direction

Miter Gears

Connect shafts at a right angle without changing speed or torque

Ratchet Gears and Pawls

Ratchet Gears and Pawls

Transmit motion in one direction and stop it in the other

Helical Gears and Racks

Helical Gears and Racks

Curved teeth stay in contact longer to transmit heavier loads at higher speeds than spur gears

Bevel Gears

Reduce speed while transmitting motion at a right angle
