mechanicalgear
A mechanical gear is a rotating machine part having cut teeth or, in the case of a cogwheel, projections on its perimeter that mesh with another toothed part, called a gear, to transmit torque. Gears are often toothed wheels that engage one another. They are a fundamental component in mechanical engineering, used to transmit rotational motion and power between shafts.
Gears can change the speed, direction, or torque of a rotating shaft. By using gears of different
The most common type of gear is the spur gear, which has straight teeth parallel to the
