<p><P>PROBLEM TO BE SOLVED: To realize a gear device capable of excellently keeping a rotational balance of a crankshaft. <P>SOLUTION: This gear device 100 has an internal teeth member 6, a carrier 2 (a support member 2X and a support member 2Y), the crankshaft 50 and an external teeth gear 16. An internAl teeth gear is formed on the inner periphery of the internal teeth member 6. The carrier 2 is arranged coaxially with the axis CL1 of the internal teeth gear. The carrier 2 is also rotatably supported by the internal teeth member 6. The crankshaft 50 is arranged coaxially with the axis CL1 of the internal teeth gear, and is rotatably supported in the carrier 2 by a pair of bearings 28. An eccentric body 20 and a first gear 32 are fixed to the crankshaft 50 between the pair of bearings 28, The external teeth gear 16 meshes with the internal teeth gear. The external teeth gear 16 also engages with the eccentric body 20. The external teeth gear 16 eccentrically rotates around the axis CL1 of the internal teeth gear in response to rotation of the crankshaft 50. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
