Power Transmission

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

Bevel Gears

Reduce speed while transmitting motion at a right angle

Helical Gears and Racks

Helical Gears and Racks

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

Ratchet Gears and Pawls

Ratchet Gears and Pawls

Transmit motion in one direction and stop it in the other

Timing Belt Drive Pulleys

Timing Belt Drive Pulleys

Pair with a timing belt to transfer motion from a rotating shaft

Drive Sprockets

Drive Sprockets

Mount directly onto a shaft to transmit rotary motion and torque

Timing Belt Idler Pulleys

Timing Belt Idler Pulleys

Add to your timing belt setup to minimize vibration and keep belts from wearing out

Idler Sprockets

Idler Sprockets

Press against your chain to take up slack and reduce wear and vibration

V-Belt Drive Pulleys

V-Belt Drive Pulleys

Pair with a V-belt to transfer motion from a rotating shaft

Gear Boxes

Adjust motor speed to achieve the right torque for your machine; transmit motion at a 90° angle

Measuring and Inspecting

Gear Tooth Gauges

Gear Tooth Gauges

Identify your gear's pressure angle, pitch, and module

Calipers

Take inside, outside, and depth measurements with more precision than a ruler
