Glossary Balancing Technology

Reference plane

Radial shaft plane to which an unbalance is referenced.

Repeatability

With a balancing machine measure for the quality of the unbalance measurement with repeated measurements under the same conditions. Normally evaluated applying statistical methods.

Reproducibility

With a balancing machine measure for the quality of the unbalance measurement with repeated measurements under different conditions. Normally evaluated applying statistical methods.

Residual unbalance

Unbalance of any kind that remains after balancing.

Rigid rotor

With a rigid rotor the deflections caused by a given unbalance distribution can be neglected up to its max. service speed.

Rotor

A body, capable of rotation, generally with journals that are supported by bearings.
