Mechanical Gears
I-How Does Gears Work?
You see gears in just about everything that has spinning parts. For example, car engines and transmissions contain lots of gears. Gears are generally used for one of four different reasons:
1- To reverse the direction of rotation.
2- To increase or decrease the speed of rotation.

Burnishing, like shaving, is used with gears which have been cut but not heat-treated. Grinding and lapping are used for hardened gear teeth after heat treatment.
