Balancing machine with direct readout
Abstract
Abstract A BALANCING MACHINE WHEREIN THE TRANSLATION OF BEARING CARRIERS, IN RESPONSE TO VIBRATION OF A TEST PART SUPPORTED ON THE CARRIERS IS DETECTED BY PICKUPS TO DEVELOP TWO TEST SIGNALS THAT ARE PROCESSED TO PROVIDE A DIRECT INDICATION OF THE WEIGHT TO BE ADDED IN A GIVEN CORRECTION PLANE AT A GIVEN CORRECTION RADIUS. THE SIGNAL PROCESSING CIRCUIT INCLUDES A SELECTOR SWITCH TO SELECT A SIGNAL FROM EACH PICKUP INDIVIDUALLY OR THE SUM OF THE SIGNALS FROM BOTH PICKUPS. THERE IS A METER SCALE SWITCH TO SELECT FULL SCALE METER DEFLECTIONS DEPENDING UPON THE WEIGHT RANGE OF THE PART UNDER TEST. THE SELECTED SIGNALS ARE ALSO PROCESSED THROUGH A CORRECTION RADIUS POTENTIOMETER AND ALSO A PART WEIGHT POTENTIOMETER THAT ARE CALIBRATED DIRECTLY IN INCHES AND POUNDS, RESPECTIVELY, SO THAT THE METER DIRECTLY READS THE WEIGHT THAT HAS TO BE ADDED AT A GIVEN CORRECTION RADIUS.
