Worm and Worm Gears sets transfer motion between nonintersecting right angle shafts. They are the most compact small precision gears system offered, and also the quietest and smoothest running. A worm and worm gears established can provide a higher reduction ratio in a very small space.

EP has been making worm and wheel equipment systems for over 30 years. We offer worms and worm gears units in a variety of inch and metric sizes and with quite a few pitch, tooth count, and hub alternatives. Our precision floor stainless steel worm and wheels and phosphor bronze worm gears provide 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 one’s teeth of a worm wheel. These tiny precision gears may have one or multiple threads (named begins). With each revolution, a single-start worm will approach the connected worm wheel by one tooth; worms with multiple starts off will move the mating worm gear a corresponding number of teeth with each revolution. (electronic.g., a 2-start worm will move the worm wheel two the teeth per revolution.)

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