Tips and tricks

A useful tip is often worth more than a thousand words

Particularly where balancing is concerned, minor inadequacies may often have a serious effect on the balancing result.


In this section, you will find the answers to many of the every-day problems that crop up in balancing – after all, you are probably not the only person battling with these problems.

Balancing of assemblies

Question:
Is it necessary to balance the individual components of an assembled rotor, and, if so, what tolerances should be applied?

Shifting balancing planes

Question:
If you shift the balancing planes of a rotor with two balancing planes, will this affect the unbalance of the rotor, and, if so, how?

Relationship between unbalance, speed, centrifugal force and rotor weight

In balancing practice, the relationship between unbalance and centrifugal force at given speed often takes on a special importance, for example, if you have to get a rough estimate of the centrifugal forces generated at operating speed at the maximum permitted unbalance.

Choosing the right mounting position

Question:
"If a rotor has two standard shaft ends - what can possibly go wrong"? The question alone contains an indication of where the problem may lie - the shaft ends may be skew.
