Filed: 1991-04-05
Abstract: PURPOSE:To automatically correct the balance of a rotary shaft by fixing a main body section having the rotary shaft which is provided with a space part for enclosing magnetic fluid to induce its self-helping action. CONSTITUTION:A ring-shaped space part 6 whose wall face is magnetized is provided concentrically from a rotary shaft 2, and a magnetic fluid 9 is enclosed inside the space part 6. When a driving shaft rotates at high speed, a centrifugal force acts onto the magnetic fluid 9, which moves on account of its self-helping action according to the quantity of the unbalance occurring on the outer wall face of the space part 6 to automatically remove the unbalance of the rotary shaft and a rotary body. A method for correcting the unbalance of the rotary body by applying the self-helping action of the magnetic fluid can automatically answer to even the continuously fluctuating unbalance without stopping the rotation of the rotary body or a special operating technique and a complicate device. Thus this method is simple in the structure of an applied device and moreover a highly precise balance correcting method for the rotary body which is characterized by low price, compactness, light weight and noiselessness.
