The wobbling inner gearing planetary gear system has planetary external gears and an internal gear with which the external gears internally mesh, a center axis of the system being located inside periphery of the external gears The method is a method of reducing angle transmission errors in the system, in which the number of teeth of the internal gear is X.n (X: even number of 4 or more; n: integer), and the difference in the number of teeth between the internal gear and external gears is 2. The external gears are superposed and machined to collectively form respective external gear teeth and through holes. The external gears are grouped into pairs and these pairs are circumferentially offset from each other by 360�/X around the center axis. One of each pair of the external gears is shifted parallel in 180� opposite direction away from the other one of each pair of the external gears. |
