PROBLEM TO BE SOLVED: To provide a small hypocycloid device capable of ensuring high reliability and durability at low cost with a simple structure.SOLUTION: The hypocycloid device uses, as two pairs of hypocycloid gear mechanisms 13, 14 interposed between input and output shafts 6, 8, two pairs of gear mechanisms 15, 16 which are a pair configured by meshing a concentric wheel 15a having the center in a position concentric with the axis of the input shaft, and an eccentric wheel 15b having the center in a position decentered from the axis of the input shaft, partially with each other, and a pair configured by meshing a concentric pinion 16a having the center in a position concentric with the axis of the input shaft, and an eccentric pinion 16b having the center in a position decentered from the axis of the input shaft, partially with each other. An eccentric cam part 18 is formed at the input shaft, and the respective gears of the two pairs of large and small gear mechanisms are concentrically arranged around the outer peripheral surface of the eccentric cam part. With this configuration, the small hypocycloid device of simple structure can be obtained. |
