ABSTRACT:
A positioning device without backlash includes a table and at least one gear operatively associated with the table. At least one worm gear is connected to the gear and the gear is driven in a desired direction with a primary motor and a synchronized slave motor. The synchronized slave motor is then reversible to remove the backlash in the positioning device thereby permitting an actual position to correspond with a dialed-in position.
