1) The difference between the internal gear and external Gear

The major difference between an internal and an external gear beside where the gear teeth are generated on the workpiece.

For example, while meshing a pair of external gears, their rotation will go in opposite directions;

ut in the meshing on an external and internal gear their rotation will go in the same direction.

Another major difference between the two types of gears is that a low ratio reduction is unsuitable

in the case of an internal and external gear, but is completely acceptable in the meshing of an external and another external gear.
