<P>PROBLEM TO BE SOLVED: To provide an oscillation type planetary gear device that can easily secure an arrangement space for piping, wiring, etc., at the center part of the device according to a use purpose, and make power transmission smoother. <P>SOLUTION: The oscillation type planetary gear device 100 which oscillates and rotates inner gear oscillation bodies 116A, 116B as oscillation gears through eccentric bodies 140A, 140B arranged at a plurality of eccentric body shafts 114A-114C respectively includes: eccentric body shaft gears 112 provided to the plurality of eccentric body shafts 114A-114C respectively; a transmission external gear 110 with which the plurality of eccentric body gears 112 are engaged; and an intermediate shaft 108 which is arranged in parallel at a position different from the center axis of rotation of the transmission external gear 110, and provided with an intermediate pinion 130 as a driving source-side pinion. The eccentric body shaft gears 112 and transmission external gear 110 are driven by rotating the driving source-side pinion 130, and the transmission external gear 110 is constituted of a single gear supported by one bearing 132. <P>COPYRIGHT: (C)2012,JPO&INPIT |
