Crown and Pinion gears - Ringgearpinions

 

Crown and Pinion gears The pinion is the segment of a gear which rotates around a central axis. The pinion connects the gear to the shaft. The pinion is the most complex part of a gear. It is responsible for turning the gear’s rotation into movement.

The gears in your car and the crown on your tooth are both used to measure torque.

When you turn the steering wheel, the gears and the crown turn, too. They use the same basic principles to measure torque, and their measurement is called torque. The amount of torque that a gear or a crown can turn is measured in Newton-meters (Nm).
