ROTOR AUTOMATIC BALANCE 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 support and filled with solidifiable material. Use as said material 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. Spring-loaded ring is radially installed on outer surface of chamber. Ring is capable of moving in radial direction under action of centrifugal forces, arising at vibration and unbalance of rotor, through distance sufficient for contacting with protective case preliminarily installed around chamber and return into initial position at disappearing of centrifugal forces under action of elastic forces of supporting springs.

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