The experimental unit can be used to demonstrate imbalance and the balancing process clearly. The difference between static and a dynamic imbalance can be shown. Imbalance is determined and balanced by appropriate measures.
The main element of the experimental unit is a smooth shaft to which four variable imbalance masses are attached at any angular and longitudinal position. The shaft is mounted on ball bearings. A variable-speed electric motor and a belt drive it. The speed of the shaft is displayed digitally.
In order to determine the imbalance, a defined external moment is applied via an additional pulley with weights. This moment is compared to the moment of the imbalance masses. A transparent cover protects against contact with rotating parts and allows a clear view of the shaft. Unwanted vibrations are suppressed by using elastic bearing for the foundation.
