A gear is a rotating machine part that utilizes cut teeth, or cogs, to mesh with another toothed part—usually another gear or a linear toothed part (called a gear rack)—to transmit rotational motion and torque. By using a combination of precision gears with the correct ratio, the speed, torque, and even direction of a power source can be changed. Two or more gears working together, called a gear train or a transmission, will almost always create a change in torque. If one gear is larger than the other, a mechanical advantage is produced; the rotational speed and torque of the respective gears differs in proportion to their diameters.
