Dufon Static and Dynamic Balancing Apparatus

Dufon Static and Dynamic Balancing Apparatus

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.
