Balancing method for elastic rotor

Abstract

Abstract PURPOSE:To reduce imbalance generated in the rotor automatically by receiving a liquefied substance, which is liquefied at a fixed temperature or higher and solidified at a fixed temperature or lower, into a hollow section formed to the rotor, sufficiently distributing the liquefied substance into the hollow section and solidifying said substance. CONSTITUTION:The elastic rotor consists of a rotor proper 8 and a journal 9, and is supported by bearings 10. The hollow section 11 is shaped to said rotor proper 8, and the liqueified substance 12, which is liqueified at a fixed temperature or higher and solidified at a fixed temperature or lower, is received into the hollow section. When the elastic rotor is turned and exceeds critical speed, the rotor is deflected in the direction opposite to imbalance force A, and the center Os is displaced in the direction opposite to imbalance force A. In this case, the liquefied substance 12 is also distributed thickly in the direction opposite to imbalance force A, centrifugal force B by the liquefied substance 12 works in the direction opposite to imbalance force A, and imbalance force A is reduced. Accordingly, the liquefied substance 12 is solidified, resonant amplitude is decreased at critical speed, and the rotor is balanced.
