Static and Dynamic Balancing Apparatus
Product Code : EL-DOMLE-10778
Quick Answer:
The Static and Dynamic Balancing Apparatus clearly demonstrates rotor imbalance and the balancing process, showing the difference between static and dynamic imbalance. Four variable masses can be attached at any angular and longitudinal position along a ball-bearing-mounted shaft, which is driven by a variable-speed electric motor and belt and whose speed is shown digitally (up to 1400 min-1); a defined external moment, applied via an additional pulley with weights, is compared against the moment of the imbalance masses to determine and then correct the imbalance, all viewed safely through a transparent cover while elastic foundation bearings suppress unwanted vibration.
The experimental unit can be used to demonstrate imbalance and the balancing process clearly, showing the difference between static and dynamic imbalance; the imbalance is determined and then balanced by appropriate measures. The main element of the experimental unit is a smooth shaft, mounted on ball bearings, to which four variable imbalance masses are attached at any angular and longitudinal position; a variable-speed electric motor and a belt drive the shaft, and its speed is displayed digitally. In order to determine the imbalance, a defined external moment is applied via an additional pulley with weights, and this moment is compared to the moment of the imbalance masses. A transparent cover protects against contact with the rotating parts while allowing a clear view of the shaft, and unwanted vibrations are suppressed by using an elastic bearing for the foundation.
