POWER TRANSMISSION DEVICE FOR VEHICLE
Document Type and Number:
Japanese Patent JP2019002479
Kind Code:
A
Abstract:
To adjust a position of center of gravity of an eccentric disc of a crank-type power transmission device without needing a balance weight.SOLUTION: An eccentric disc 19 is composed of a first part 51 positioned at an eccentric side and a second side part 52 positioned at an anti-eccentric side, and as the second part 52 and a part 53 of a ring gear connected to the first part 51 are composed of a material of high specific gravity and high strength with respect to a material of the first part 51, a position of center of gravity G of the eccentric disc 19 is adjusted to a center O1 side of the ring gear 19b without disposing a special balance weight, and generation of vibration can be prevented while reducing a size and a weight of the eccentric disc 19. Further the strength can be secured by making the whole ring gear 19b stranding over both of the first part 51 and the second part 52, by using the material of high specific gravity and strength.SELECTED DRAWING: Figure 3
