Abstract:
1. An oscillating internally meshing planetary gear reducer for reducing a speed of an input power via an oscillating external gear, comprising: an input gear which is circumscribed and meshed with a pinion rotating at the same speed as that of an output shaft of an external power source; an input shaft provided with the input gear to receive driving force from the pinion; an input shaft gear mounted on the input shaft; a plurality of eccentric body shafts each provided with an eccentric body for oscillating the oscillating external gear; an eccentric body shaft gear which is mounted on at least one of the eccentric body shafts to make the eccentric body shaft receive the power; and a distributing gear which meshes with the input shaft gear and the eccentric body shaft gear to distribute and transmit rotation of the input shaft gear to the plurality of eccentric body shaft gears.
