Internal Spur Gear

Internal Gears have the teeth generated on the I.D. of the blank. 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 occur.
