Abstract: A highly effective, multi-purpose mechanical snubber is achieved by providing an elongated, centrally disposed, axially moveable rack member controllably engaged with at least one worm gear, having an axis of rotation substantially parallel to the central axis of the rack member and mounted for rotation about said axis in response to axial translation of the rack member. In one embodiment, the mechanical snubber also incorporates an inertial mass which is rotationally responsive to the rotational movement of the worm gear. By employing one or two worm gears and rotationally driving the inertial mass in similar or opposed directions, various alternative vibratory control systems are achieved with the single mechanical snubber construction of this invention.
