摘要
PROBLEM TO BE SOLVED: To provide an automatic aligning function with supporting operation of a planet gear, especially provide a reduction gear with back lash reduced by a simple method, and prevent generation of an inconvenience of a radial moment, in a simple planet gear mechanism.;SOLUTION: A carrier pin 30 is eccentric by (e) to a shaft center Cro of the carrier pin 30 and is provided with a crank portion with a variable eccentric angle α. The planet gear 14 is rotationally supported with a rotation center at a shaft center Co of the crank portion 32. As the result, when each gear is assembled, the shaft center Co is automatically aligned in a radial direction, due to the variable eccentric angle α, and by merely assembling a sun gear in a proper dimension, the back lash can be regulated into the minimum. The reference of the shaft center CRo of the carrier pin 30 is set in the case where each gear is fabricated in the center of a machining tolerance.;COPYRIGHT: (C)2002,JPO
