Internal gears, also called ring gears, have the same standards as external gears, except that the teeth are cut into the inner diameter while the outside remains smooth. Internal gears can provide a compact solution, provide large speed reduction and reduce sliding wear action, and can be applied to a wide range of equipment and amplifiers; applications. Internal gears are widely used in light load applications.

An internal gear can be described as the opposite of an external gear, where the tooth points rather than away from the center, and takes the opposite position to the tip and the root of the tooth. The internal gear provides a compact parallel shaft transmission drive with large speed cuts. The ratio of using a standard spur gear is the same for the two external gears, but the center distance is smaller. In the case, it is necessary to have two parallel shafts rotating in the same direction, and the internal gear eliminates the use of idler gears.
