<p>Vibration compensator apparatus comprising a housing (1, 11) where two shafts (4, 4', 14, 14') are journaled, each shaft having an excentric mass provided by rotary bodies (22, 22'). The shafts (4, 4', 14, 14') are arranged to rotate around two mutually parallel axes of rotation (5, 5', 15, 15') and are interconnected in order to rotate with the same number of revolutions but in opposite directions in order to generate a resulting force component equal to zero in one direction as well as a second resulting force component harmonic between zero and twice the force (F) of the individual excentric mass in a direction perpendicular to the first one. The shafts (4, 4', 14, 14') are interconnected in such a way that the forces generated by the two excentric masses always point in a direction away from each other when the resulting, harmonic force component is zero. The distance between the shafts (a) is less than the diameter of the area defined by the rotation of the shafts (4, 4', 14, 14') and their rotary bodies (22, 22').</p> |
