Imbalance in rotating machines is a common source of the vibration excitation For a rotor with a constant unbalanced mass only one-time balancing is sufficient However if the rotor has variable unbala

The ABB is mounted on the rotor shaft and rotates with it. As the rotor rotates, the unbalanced mass causes the ABB to move along the groove, and the weights inside the groove move to the position of maximum imbalance. The weights then exert a force on the rotor in the opposite direction, reducing the unbalance. The damping fluid helps to slow down the motion of the weights and prevent excessive movement, which could cause further imbalance.

The ABB can operate continuously, providing automatic balancing during the entire running time of the machine. It is particularly useful for machines with variable running conditions, such as washing machines with changing loads, or lathes with varying cutting forces. The ABB can also be used in conjunction with one-time balancing to improve overall balance and reduce vibration levels.

Overall, the automatic ball-balancer is an effective solution to reduce the unbalancing effects in rotating machines and improve their performance and reliability
