Note: Because the effectiveness of a worm equipment drive depends on the lead position and number of starts on the worm, the ratio ought to be kept low. To run correctly, worms and worm gears operating together will need to have the same diametral pitch and threads.

EP Gear offers worm gears manufactured from a number of materials, such as for example acetal, minlon, bronze, and cast iron to suit your application’s requirements.

The pinion meshes with one’s teeth of the worm gear at 90 degrees, and motion is transmitted to the worm wheel when the worm pinion is rotated. Because the pinion is captivated axially, this rotation causes the worm wheel to rotate. The ratio of the worm established can be altered by changing the amount of the teeth on the wheel or changing the amount of starts on the pinion.
When used with EP Equipment worms, EP Gear’s worm gears provide effective power tranny in applications requiring high-ratio speed reduction in a restricted space using right position (90°), nonintersecting shafts. They are also the smoothest, quietest form of gearing when properly applied.

Just how do Worm Gear Sets Transmit Motion?

A worm gear arranged is a set of gears consisting of a worm (pinion) and a worm-wheel (worm equipment), often used whenever a high ratio is necessary and space is bound.
