ABSTRACT:
A angular velocity modulating device comprises: a primary angular velocity modulating means including a first non-circular gear which is an internal gear rotatably supported and a second non-circular gear which is an external gear mounted on a second rotary shaft and engaged with the first non-circular gear; a secondary angular velocity modulating means including the first non-circular internal gear and a third non-circular gear which is an external gear mounted on a third rotary shaft and engaged with the first non-circular gear; a first frame rotatably supporting the first non-circular gear and the second rotary shaft; and a second frame rotatably supporting the third rotary shaft, the ratio in angular velocity of the third rotary shaft to the second rotary shaft being the quotient of the secondary angular velocity ratio of the first and second non-circular gears divided by the primary angular velocity ratio of the first and third non-circular gears, whereby the device can be small in size in a radial direction.
