Dynamic balancing

Free centrifugal forces and movements, present in unbalanced or poorly balanced rotary parts, must be avoided due to several reasons. In determined circumstances these forces may be dangerous as they originate the following phenomena:

1. Very high dynamic pressures at the supports that are superimposed to the static pressures and cause premature wear in the bearings.
   
2. Fatigue associated breaks in bearing blocks, bed plates and foundations. Sudden, unexpected breaking of rotary elements are a serious risk that can come up particularly when machines ,turning at high speed, come through the resonance zone of their shafts, casings, or the building and soils where they are erected. The balancing reduces the exciting forces and minimizes the difficulties that arise when crossings the resonance speeds. The natural resonance speeds of buildings are most of the times between 1.000 and 3.000 r.p.m., which is coincidental with the operating speed of most industrial machinery.
   
3. Security danger in unions made by means of screws or keys, which can be loosened by vibrations . Catastrophic separation if bolts or nuts become loose when turning at high speed .
   
   
4. Disturbing noises which, at elevated speed, can be perceived even at great distance. The quiet, vibration free operation is always, consciously or not, taken as a basis to ponder the accuracy of the balance and also to qualify the category of a machine.

Good balancing always brings an increase in security of service, in machine durability and usability.

As a consequence, it is easy to realize that dynamic balancing must be demanded not only for pure technical reasons but also for economical reasons.

Enumerating the list of the different types of machines that have passed our works to be balanced will take us to name more than hundred different applications.
