representation of the fundamental processes involved in balancing
- Imbalances on rotating machines are often the cause of disruptive vibrations and noise. During imbalance, the principal axis of inertia or centre of gravity of the rotating machine component is outside its axis of rotation.
- By adding or removing masses, the centre of gravity or the principal axis of inertia can be shifted so that both coincide with the axis of rotation.
- This process is called balancing.
- The machine component is then balanced and runs without vibration.
- The TM 170experimental unit can be used to demonstrate imbalance and the balancing process clearly.
- The difference between a 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.
- It is driven by a variable-speed electric motor and a belt.
- 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 an elastic bearing for the foundation.
