Title:
PLANETARY GEAR DEVICE
Document Type and Number:
Japanese Patent JP2017172656
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a planetary gear device which reduces mating noise of gear.SOLUTION: A planetary gear device 1 includes an eccentric shaft 40 provided in radial inner direction of a first rotator 20 connected to a crank shaft 13 and a second rotator 30 rotatable integrally with an output shaft 33, a planetary rotator 45 provided between the first rotator 20 and the second rotator 30, and the eccentric shaft 40, and springs 51, 52 provided between the eccentric shaft 40 and the planetary rotator 45. The eccentric shaft 40 can rotate around an axial center Ax1 of a first inner gear 201 possessed by the first rotator 20 and has an eccentric part 42 which is off-centered to the axial center Ax1. The springs 51, 52 energize the planetary rotator 45 in the direction in which the eccentric part 42 is off-centered, at the same time, energize the planetary rotator 45 in a direction intersecting the direction in which the eccentric part 42 is off-centered and suppress inclination of an eccentric axial center Ae1 for the axial center Ax1.SELECTED DRAWING: Figure 1
