Abstract
Vibration analyzing apparatus of the type employing a phase angle meter for determining the angular location of a point of unbalance on a rotating member with respect to a mark on the member, and capable of determining the approximate balance correction weight and its location about the rotor circumference the first time a rotor is spun up. Application of the indicated correction weight will reduce the unbalance on most typical rotors, assuming that they are approximately symmetrical about the center point of the longitudinal axis of the rotor. The apparatus enables most rotors to be balanced with a reasonable degree of accuracy without the necessity for adding trial weights, utilizing plane separators, or shaking with a known force in order to calibrate the apparatus.
