ABSTRACT:
A worm drive system includes a worm wheel having two sets of angularly arranged rollers. Each set of rollers mates with a separate screw thread on a worm screw associated with the worm wheel. The worm drive system may also include a second worm screw having two separate screw threads, each one mating with a corresponding set of rollers on the worm wheel. The worm drive system may be used as a speed increaser and/or a speed decreaser by suitably selecting the ratio between the worm wheel and the worm screws. The worm screws rotate in the same angular direction if the screw threads on one worm screw have the same hand, which is different from the hand of the screw threads on the other worm screw. The worm drive system also has a load-sharing capability and an anti-backlash capability.
