worm gear set

Note: Because the efficiency of a worm gear drive depends on the lead angle and number of starts on the worm, the ratio should be kept low. To perform properly, worms and worm gears operating 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 is usually captivated axially, this rotation causes the worm wheel to rotate. The ratio of the worm arranged can be altered by changing the number of teeth on the wheel or changing the amount of starts on the pinion.
When used with EP Gear worms, EP Gear’s worm gears provide effective power tranny in applications requiring high-ratio speed reduction in a limited space using right position (90°), nonintersecting shafts. They are also the smoothest, quietest kind of gearing when correctly applied.

How do Worm Gear Pieces Transmit Motion?

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