ABSTRACT:
A motor-driven rotating table positioning device has a bullgear engaged by two pinions each driven by the high-efficiency worm and gear set. These two worm and gear sets are connected by a coupling shaft and an adjustable coupling which allows a desired torsion to be maintained in the coupling shaft thereby eliminating any table backlash caused by the bullgear, pinions and high-efficiency worm and gear sets. For safety in the event of motor failure, the motor is coupled to the coupling shaft by a low-efficiency or self-locking worm and gear set.
