There are many documented “good consequences” and benefits associated with a well balanced, smooth running rotor. Included among these are:
Unbalance is still the major source of machine vibration.
Airborne noise is often directly attributable to mechanical vibration.
Minimize structural stress
The forces produced by unbalance have to be absorbed by the surrounding structure.
Minimize operator fatigue and annoyance
Exposure to high levels of vibration and noise affects operator efficiency.
Increase machine life
The time between outages can be extended if the machine is running smoothly.
Increase bearing life
Bearings bear the brunt of the unbalance forces.
Increase product quality
Minimum vibration, especially on machine tools, produces better parts.
Increase personnel safety
Dangers associated with machine failure are minimized.
Machines running smoothly have more “uptime” availability
