REDUCTION GEAR, REDUCTION GEAR WITH MOTOR AND ROTARY DRIVE DEVICE OF ROTATED MEMBER EQUIPPED WITH REDUCTION GEAR WITH MOTOR

摘要

PROBLEM TO BE SOLVED: To provide a reduction gear, reduction gear with a motor and a rotary drive device which facilitate wiring to a motor from one side in an axial direction of the reduction gear in the wiring to the motor disposed on the other side.;SOLUTION: The reduction gear 100 is of an eccentric oscillation type including an internal tooth element 2 having a pin 1 as an internal tooth, an external gear 4 having an external tooth 3 meshing with the internal tooth pin 1, a plurality of crankshafts 6 as a crank body for forcing the external gear 4 to perform the eccentric movement through the mesh of the drank part 5 with the external gear 4, and a supporting body 7 for freely rotatably supporting the crankshaft 6. A through hole 9 is formed to the supporting body 7 to make the wiring 10 to a motor 8 run to one end of the supporting body 7 through the through hole 9 in the supporting body 7 from the other end of the supporting body 7, and connected to the motor 8. A rotary drive device keeps the supporting body 7 in the base end side arm 200 of a manipulator and a rotating arm 300 in the internal tooth element 2 as the rotated member, and rotates a rotated member 300.;COPYRIGHT: (C)2009,JPO&INPIT
