Rotating table positioning device with minimum backlash

This rotary table is intended primarily for use in arc welding. USPTO records show that this patent was originally assigned to Airco, Inc., and on 1985-09-27 that assignment was transferred to K. N. Aronson, Inc.
"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." |
