Worm and Worm Gears models transfer motion between non-intersecting right angle shafts. They are the most compact little precision gears system obtainable, in addition to the quietest and smoothest running. A worm and worm gears collection can provide a higher reduction ratio in a very small space.

EP has been making worm and wheel gear systems for over 30 years. We offer worms and worm gears models in a variety of inch and metric sizes and with many pitch, tooth count, and hub options. Our precision ground stainless steel worm and tires and phosphor bronze worm gears provide the best accuracy, smoothest procedure, and longest working lifestyle.

EP’ High Performance 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 little precision gears may possess one or multiple threads (referred to as starts off). With each revolution, a single-start worm will approach the affiliated worm wheel by one tooth; worms with multiple starts will move the mating worm equipment a corresponding amount of pearly whites with each revolution. (e.g., a 2-start worm will move their worm wheel two pearly whites per revolution.)

Standard worm gear worm wheels feature straight, helical-cut teeth and provide only 1 point of connection with the worm. EP presents “throated” worm wheels with curved, helical-cut the teeth whose curves meet the radius of the worm itself. Throated worm wheels provide a much greater contact area, which vastly increases load capability and longevity.

That’s all on metric worm gears, thinking about more?
