ABSTRACT:
When second rotating bodies are made eccentric, the second rotating bodies move straight in the radial direction along first rotating bodies. Therefore, the cyclically changing angular velocity of the second rotating body changes so that the side on which the angular velocity is higher than the angular velocity of the input-side rotating body and the side on which the angular velocity is lower are symmetrical to each other. Also, on both of the side on which the angular velocity is higher and the side on which it is lower, the acceleration side and the deceleration side change symmetrically to each other. On the other hand, the angular velocity of the second rotating body such that the movement direction with respect to the first rotating body is shifted 180 degrees with each other with the input-side rotating body being the center changes symmetrically with respect to the angular velocity of the input-side rotating body. Moreover, since the second rotating bodies have the same mass, the radial forces of the second rotating bodies are canceled each other, so that the rotational force always acts with the input-side rotating body being the center.
