ABSTRACT:
A planetary gear includes a middle planetary gear part, a disc part on one side of the planetary gear part having a radius smaller than a radius of the tooth root circle of the planetary gear part and another disc part on another side of the planetary gear part having a radius bigger than a radius of a tooth edge circle of the planetary gear part. An internal gear includes a middle internal gear part, an inner cylindrical part on one side of the internal gear having a radius smaller than a radius of a tooth edge circle of the internal gear part and another inner cylindrical part on another side of the internal gear having a radius bigger than a radius of a tooth root circle of the internal gear part. The planetary smaller disc parts can rollingly engage the smaller inner cylindrical part of the internal gear. The planetary bigger disc parts can rollingly engage the bigger inner cylindrical part of the internal gear. The planetary gear part and two disc parts are unified in a body. Unification of the planetary gear reduces the cost of manufacturing and assembling and additionally, alleviates noise generation from the operating assembly.
