Filed: 1984-04-10
Abstract: PURPOSE:To automatically adjust balance, by occasionally detecting a direction and an amount of unbalance under an operating condition by a simple method with an unexpensive device. CONSTITUTION:A hollow disc 8 is mounted to a shaft 7 of a rotating body 6. Large and small annular grooves are formed in the hollow disc 8 by guide links 9, and tubes 3 and 5 are provided in the grooves. The tubes 3 and 5 are provided with a pressure air intake valve 1 and a pressure reducing valve 2, respectively. A plurality of hollow balls 4 made of light materials and having a diameter slightly greater than that of a section of the tubes are inserted in the tubes. The tubes 3 and 4 are fitted in the disc 8, and the disc 8 is sealed by a transparent upper cover 10. Then, air is supplied to the tubes 3 and 5 to allow free movement of the balls 4, and a residual space of the grooves is filled with water. Pressure in the tube 5 is set to be reduced after a fixed period of time when pressure in the tube 3 is reduced by the pressure reducing valve 2, and the disc 8 is started to rotate. As a result, the balls 4 are moved by a centrifugal foece, and then are positioned due to shrinkage of the tubes to thereby effect adjustment of balance.
