Worm and Worm Gears sets transfer motion between non-intersecting right angle shafts. They will be the most compact small precision gears system offered, in addition to the quietest and smoothest operating. A worm and worm gears arranged can provide a higher reduction ratio in an exceedingly small space.
EP has been developing worm and wheel gear systems for over 30 years. We offer worms and worm gears units in a variety of inch and metric sizes and with numerous pitch, tooth count, and hub choices. Our precision ground stainless worm and tires and phosphor bronze worm gears provide the best accuracy, smoothest operation, and longest working existence.

EP’ High Performance Worm Gear Systems
A worm is configured similarly to a machine screw, but with tooth made to mesh with the teeth of a worm wheel. These tiny precision gears may possess sole or multiple threads (named starts). With each revolution, a single-start worm will move the linked worm wheel by one tooth; worms with multiple starts off will approach the mating worm gear a corresponding number of the teeth with each revolution. (electronic.g., a 2-begin worm will move their worm wheel two pearly whites per revolution.)
Standard worm equipment worm wheels feature right, helical-cut teeth and offer only one point of connection with the worm. EP gives “throated” worm wheels with curved, helical-cut teeth whose curves match the radius of the worm 
itself. Throated worm tires provide a much greater speak to area, which vastly boosts load capability and longevity.
