Abstract
An antivibration device for reducing the vibration of a structure, includes a stationary casing, mounted on the structure, and first and second sets each including two contra-rotary rotors having eccentric flyweights, the flyweights and the rotors being disposed respectively in first and second mutually parallel planes, the centers of rotation of the contra-rotary rotors representing the corners of a rectangular parallelogram in the second plane, and the axes of rotation of the contra-rotary rotors being mutually parallel and orthogonal to the first plane. In addition, it includes a stationary main motor secured to the casing with a through shaft having a first end driving the contra-rotary rotors of the first set and a second end driving the contra-rotary rotors of the second set.
