Abstract:
1. An oscillating inner gearing planetary gear system, comprising: an internal gear; an external gear that meshes with the internal gear; an eccentric body that oscillatingly rotates either the internal gear or the external gear; an input shaft; an output member; a middle shaft having an orthogonal gear, the orthogonal gear linking the middle shaft to the input shaft at a right angle; and a main casing that houses the oscillating inner gearing planetary gear system, wherein either the internal gear or external gear is oscillatingly rotated via the input shaft, the orthogonal gear, the middle shaft, and the eccentric body, the main casing houses the internal gear and the external gear inside the main casing such that the orthogonal gear links the middle shaft to the input shaft at the right angle in the same single space including the internal gear and the external gear inside the main casing, and the main casing is a single casing.
