ABSTRACT:
The present invention relates to a device for determining the angular position in a balancing machine for rotating pieces. The device according to the invention basically comprises means for counting memorizing and visualizing the number of constant frequency pulses which are delivered by a first pulse generator between a reference moment at which a second pulse generator delivers a reference pulse representative of a predetermined angular position of the rotating piece and the moment at which a vibration indicator delivers a pulse indicative of the angular unbalance position.
The number of pulses counted between said moments represents the phase difference between the unbalance position and the predetermined angular position and is therefore indicative of the unbalance position.
