Internal gear
An internal gear is one with the teeth formed on the inner surface of a cylinder or cone. They are generally stronger and more efficient than the mating pinion gear. The pitch diameter of the internal gear must be at least 1.5 times the P.D. of the mating pinion. If this condition is not met, interferences between the tips of the teeth will be occured.
