Series of simple planetary gear device and manufacturing method of the simple planetary gear unit

摘要

PROBLEM TO BE SOLVED: To satisfactorily attain and maintain minimum backlash without generating a spatial trouble by using the small number of part items.;SOLUTION: A planetary gear 16 is assembled while regulating an eccentric direction so as to be meshed with an internal gear 16 in a state of being most approached to the internal gear 18 by using a dummy carrier pin having a (radially movable) rotary support part having an axis eccentric with respect to an axis of the carrier pin, and capable of supporting rotatably the planetary gear around the rotary support part, a sun gear 14 is thereafter selected to be assembled, the dummy carrier pin is pulled out after fixing a position and the eccentric direction of the carrier pin by using a fixing jig, and an eccentric carrier pin 34 used in actual transmission is pressed into a carrier body 30 in the fixed position fixed by the dummy carrier pin.;COPYRIGHT: (C)2008,JPO&INPIT
