ABSTRACT:
Machine for rapidly rotating and sensing imbalance of automotive drive shafts. Spindles including independent vibration sensors are rigidly secured to mounting blocks seated on a pair of rails integrally cast in a horizontal surface of a concrete base. A gear engaging a rack seated in a recess cast in the same horizontal surface senses to move one of the mounting blocks and its spindle and a plug also operable in the recess selectively locks the mounting block in position. Visual indicators are provided for simultaneously displaying vibrations sensed at each end of the driveshaft.
