- Main Parameters
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.
An internal gear can be described as the opposite of an external gear, where the tooth points rather than away from the center, and takes the opposite position to the tip and the root of the tooth. The internal gear provides a compact parallel shaft transmission drive with large speed cuts. The ratio of using a standard spur gear is the same for the two external gears, but the center distance is smaller. In the case, it is necessary to have two parallel shafts rotating in the same direction, and the internal gear eliminates the use of idler gears.
