Internal gears have several advantages when properly applied. One of the benefits is that the sliding effect is reduced. The corresponding tooth surfaces of the internal gear and the pinion gear are closer to the same length than when the external gear and the pinion gear have the same gear ratio and tooth length. Therefore, the relative slip of the teeth is less inside the case. This point brings up one of the advantages of using internal gears. The sliding action of one tooth on the other tooth causes friction; since friction causes tooth wear, it is advisable to reduce the sliding action. 

The tooth profile is a reverse involute, which is a conjugate involute, just like an external gear is dug out of a discus. Basically, medium carbon steel is used for quenching and tempering, the carburized ring gear is basically a small modulus, and the gear is processed by wire cutting after heating.
