Abstract

PURPOSE: To make it needless to greatly heighten the machining accuracy of each constituent member, by providing each planet gear with circular fitting holes for bearings so that the holes are eccentric toward a ring gear as to the centers of gyration of the bearings.
CONSTITUTION: Fitting holes 9d for pairs of ball bearings 12, 13, which are provided in the central parts of three planet gears 9, are circular and have their centers O2 eccentric toward a ring gear 17 as to the centers O1 of gyration of the ball bearings 12, 13 so that the three plant gears 9 can be displaced in the radial directions relative to the pairs of ball bearings 12, 13. A pair of annular members 24, 25 fitted inside the pairs of circular fitting parts 9b, 9c of the planet gears 9 are displaced together with the three planet gears 9 by the difference among the components (at the side of a sun gear 5) of resultants of tooth forces which act to the three planet gears 9.
