Internal Gears are belonging to Cylindrial Gears. The difference comparing to spur gears and helical gears are the teeth been cut on the inner surface. They typically mesh with a smaller external gear known as a pinion gear or a planet gear. Its greatest advantage is enabling highly efficient, high-torque transmission within a confined space.

Features:
(1) When meshing two external gears, the rotation occurs in the opposite directions. When meshing an internal gear with an external gear the rotation occurs in the same direction.
(2) Care should be taken with regard to the number of teeth on each gear when meshing a large (internal) gear with a small (external) gear, since three types of interference can occur.
(3) Usually internal gears are driven by small external gears.
(4) Allows for a compact design of the machine.
