Method and apparatus for ascertaining and indicating the angular position of an unbalance in a rotor

摘要

The unbalance angle is transformed into units of length or into non-dimensional units which are correlated to the body to be balanced, either to a circumference thereof, or to a characteristic scale of the body to be balanced. The unbalance position may then be displayed in such units. The apparatus for performing the method includes a transformation computer which transforms the measured angular value through at least one operant. Preferably, the apparatus also includes an indicator device for units of length or for non-dimensional units or angle representing units.
