TORQUE VIBRATION DAMPER Russian patent published in 2005 - IPC

FIELD: mechanical engineering, in particular, equipment for elimination of spurious vibrations of rotating bodies.

SUBSTANCE: torque vibration damper has casing mounted on rotating shaft and provided with annular cavity to be filled with working fluid, and permanent magnets made in the form of axially magnetized plates radially laid in pairs on cavity bases in opposed relation with respect to one another, with opposite poles facing one another with minimal distance from one another in circumferential direction, said distance exceeding height of cavity. Working fluid is combination of ferromagnetic liquid and high-viscosity liquid immiscible with ferromagnetic liquid.

EFFECT: increased damping effectiveness, simplified construction and reduced power losses in the process of rotation of bodies.
