Abstract
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.
Claims19
A method for indicating the angular position of an unbalance in a rotary body to be balanced in a balancing machine, comprising ascertaining the angular position of the unbalance with respect to a reference on the body, in the form of an angular position representing electrical signal, transforming said angular position representing electrical signal to correspond to linear measurement units which are automatically referenced to the circumference of the body to be balanced, whereby these measurement units are transferrable to the circumference of the rotary body, and supplying said transformed and referenced electrical signals to an indicator means for display.
In an apparatus for indicating the angular position of an unbalance in a rotary body to be balanced in a balancing machine, which provides an electrical signal representing said angular position, the improvement comprising circuit means for transforming said electrical signal into units corresponding to linear measurement units on the circumference of said rotating body, operant means connected to said circuit means for providing a reference relative to which said transforming takes place;
- and display means connected to said circuit means for displaying the display units.
