Static & Dynamic Balancing Demonstrator

The main element of the bench top unit is a smooth shaft to which four disc with variable unbalance weights can be attached at any angle or distance. The rotor is supported horizontally in ball bearings and is driven by a speed-controlled motor. For determination of the unbalance weight by measuring the balance of moments the driving belt can be removed. Using different weights dragging on the pulley defined moments can be exerted to the shaft. They can be compared with those caused by the unbalance weights when rotating. Fastening of the supporting base with spring neutralizes undesirable vibrations.
