<p><P>PROBLEM TO BE SOLVED: To improve operability by securing a high acceleration ratio to input high-speed rotation to a motor generator and enabling an operator to easily stop the tip part of a revolving body at a desired position. <P>SOLUTION: An external tooth gear 22 penetrated by a crankshaft 20 freely rotatably held to a carrier 21 is meshed with internal teeth 15 on the inner periphery of a case 11 and eccentrically swing-rotated. A first input/output shaft 12 is connected to a rotating shaft 10a of the motor generator 10, and a second input/output shaft 14 is integrally formed at a base part carrier 23 of the carrier 21. The rated speed of the motor generator 10 is set into a range of 6,000-10,000 rpm, and the acceleration ratio from a pinion 17 meshed with a ring gear 103 up to the first input/output shaft 12 is set into a range of 60-110. The sum total of the amount of backlash from the first input/output shaft 12 up to the pinion 17 is set into a range of 0.25-0.50°. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
