Gears are used in tons of mechanical devices. They do several important jobs, but most important, they provide a gear reduction in motorized equipment.This is key because, often, a small motor spinning very fast can provide enough power for a device, but not enough torque. With a gear reduction, the output speed can be reduced while the torque is increased. Another thing gears do is adjust the direction of rotation. If you want to create a high gear ratio, nothing beats the worm gear. In a worm gear, a threaded shaft engages the teeth on a gear. Each time the shaft spins one revolution, the gear moves one tooth forward. e.g If the gear has 40 teeth, you have a 40:1 gear ratio in a very small package.
