Note: Because the performance of a worm equipment drive depends on the lead angle and number of begins on the worm, the ratio ought to be kept low. To perform properly, worms and worm gears working together will need to have the same diametral pitch and threads.

EP Gear provides worm gears produced from a variety of materials, such as 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. Since the pinion can be captivated axially, this rotation causes the worm wheel to rotate. The ratio of the worm set can be changed by changing the number of tooth on the wheel or changing the number of begins on the pinion.
When used with EP Equipment worms, EP Gear’s worm gears provide effective power transmission in applications requiring high-ratio speed reduction in a limited space using right angle (90°), nonintersecting shafts. Also, they are the smoothest, quietest kind of gearing when correctly applied.

How do Worm Gear Pieces Transmit Motion?

A worm gear set is a set of gears comprising a worm (pinion) and a worm-wheel (worm equipment), often used when a high ratio is required and space is limited.
