Note: Because the performance of a worm gear drive depends upon the lead position and number of begins on the worm, the ratio should be kept low. To perform correctly, worms and worm gears operating 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 definitely captivated axially, this rotation causes the worm wheel to rotate. The ratio of the worm set can be changed by changing the amount of tooth on the wheel or changing the number of begins on the pinion.
When used in combination with EP Equipment worms, EP Gear’s worm gears provide effective power transmission in applications requiring high-ratio speed decrease in a restricted space using right position (90°), nonintersecting shafts. They are also the smoothest, quietest kind of gearing when properly applied.

How do Worm Gear Pieces Transmit Motion?

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