Note: Because the efficiency of a worm equipment drive depends on the lead angle and number of starts on the worm, the ratio should be kept low. To perform correctly, worms and worm gears operating together must have the same diametral pitch and threads.

EP Gear offers worm gears manufactured from a variety of materials, such as acetal, minlon, bronze, and cast iron to fit 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 certainly captivated axially, this rotation causes the worm wheel to rotate. The ratio of the worm set can be modified by changing the amount of teeth on the wheel or changing the amount of begins 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 angle (90°), nonintersecting shafts. Also, they are the smoothest, quietest kind of gearing when properly applied.

How do Worm Gear Sets Transmit Motion?

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