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

EP Gear offers worm gears produced 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 movement is transmitted to the worm wheel when the worm pinion is rotated. Since the pinion is captivated axially, this rotation causes the worm wheel to rotate. The ratio of the worm arranged can be altered by changing the number of the teeth on the wheel or changing the number 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. Also, they are the smoothest, quietest kind of gearing when correctly applied.

How do Worm Gear Models Transmit Motion?

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