The drive gear is the gear that is turned by an outside effort, for instance your hand or an
engine. Any gear that is turned by another gear is called a driven gear or follower. The drive gear
provides the input force and the driven gear delivers the output force.
Using a gear system can create change in speed, direction, and force. But there are always
advantages and disadvantages. For example, you cannot have both more output force and an
increase in speed at the same time.
To determine the ratio of which two meshed gears will move relative to each other, divide the
number of teeth on the driven gear by the number of teeth on the drive gear. This is called the
gear ratio. If a driven gear with 24 teeth is meshed with a drive gear with 48 teeth, there is a 1:2
gear ratio. That means the driven gear will turn twice as fast as the drive gear.
Gears are found in many machines where there is the need to control the speed of rotary
movement and turning force. Common examples include power tools, cars, and egg beaters!
