PASSIVE DYNAMIC INERTIAL ROTOR BALANCE SYSTEM FOR TURBOMACHINERY Russian patent published in 2016 - IPC G01M1/36 G01M1/30 F16F15/32 F01D25/00 

FIELD: turbo-machines.

SUBSTANCE: group of inventions relates to balance system for rotor used for turbomachinery. Passive dynamic inertial rotor balance system including a plurality of balancing members fitted onto a rotor shaft at locations of predicted maximum shaft modal deflection. Each of the balancing members has at least one chamber and located within the at least one chamber is a plurality of movable weights and a viscous fluid. As the shaft accelerates toward an unbalance point, the weights move within the at least one chamber to a location which is opposite from the unbalance point. Viscous fluid provides damping for the movable weights to prevent excess movement within the chamber and to provide lubrication thereof. Also disclosed is a system for self-correcting an unbalance of a turbomachinery rotor during rotation of the rotor and a method for balancing a rotor in a turbomachinery.

EFFECT: group of inventions is aimed at creating constant and inexpensive system and method for dynamic balancing of rotor which self corrects at imbalance when rotor operates.
