Worm and Worm Gears sets transfer motion between non-intersecting right angle shafts. They are the most compact tiny precision gears system available, and also the quietest and smoothest operating. A worm and worm gears collection can provide a higher reduction ratio in a very small space.
EP has been production worm and wheel gear systems for over 30 years. You can expect worms and worm gears pieces in various inch and metric sizes and with many pitch, tooth count, and hub options. Our precision ground stainless worm and tires and phosphor bronze worm gears supply the best accuracy, smoothest operation, and longest working life.

EP’ POWERFUL Worm Gear Systems
A worm is configured similarly to a machine screw, but with teeth designed to mesh with the teeth of a worm wheel. These small precision gears may have solo or multiple threads (referred to as starts). With each revolution, a single-start worm will maneuver the affiliated worm wheel by one tooth; worms with multiple starts will approach the mating worm gear a corresponding amount of pearly whites with each revolution. (e.g., a 2-start worm will 
move its worm wheel two pearly whites per revolution.)
Standard worm gear worm wheels feature right, helical-cut teeth and offer only 1 point of contact with the worm. EP offers “throated” worm tires with curved, helical-cut the teeth whose curves match the radius of the worm itself. Throated worm wheels give a much greater speak to area, which vastly enhances load capability and longevity.
