ROTOR AUTOMATIC BALANCER Russian patent published in 2004 - IPC

FIELD: mechanical engineering.

SUBSTANCE: invention is designed for balancing rotating members of machines and mechanisms. Proposed automatic balancer contains balancing chamber installed on supports and filled with solidifiable material. Used as said materials are low-melting materials capable of repeatedly changing their aggregative state. Solidifiable material plays part of balancing mass. Balancing chamber is partially filled with solidifiable, material and it is made in form of hollow cylinder located inside rotor. Expanding clutch is installed on rotor shaft which, under action of centrifugal forces caused by vibration and unbalance of rotor rotating at working frequency, sets into operation an electric generator installed preliminarily coaxially with rotor. Current leads of electric generator are connected to electric heating spiral located on inner walls of balancing chamber.

EFFECT: improved reliability of device used at different operating conditions of rotation systems.
