PURPOSE:To check vibrating torque applied on a rotating shaft depending on a vibration eliminating torque generated by a pair of rotors by arranging the rotors having an eccentric mass so as to make a planetary motion about the rotating shaft. CONSTITUTION:In the vibration eliminating torque 7 generated by rotors 5 and 5', a vibration eliminating torque 7Fl is generated when a centrifugal force produced with the rotation of eccentric masses 6 and 6 to the position illustrated is represented by F and the distance between centers c and c' of the rotors 5 and 5' by l and it is transmitted to a shaft 1 by way of a ring gear 4, torque transmission gears 3 and 3' and a main gear 2 to work opposite to a vibrating torque T. Therefore, the vibrating torque can be eliminated by setting the eccentric masses so that the vibration eliminating torque Fl equals the vibrating torque T. |
