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

EP Gear provides worm gears manufactured from a variety 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. Because the pinion is usually captivated axially, this rotation causes the worm wheel to rotate. The ratio of the worm arranged can be modified by changing the number of the teeth on the wheel or changing the number of begins on the pinion.
When used in combination with EP Gear worms, EP Gear’s worm gears provide effective power transmission in applications requiring high-ratio speed decrease in a limited space using right angle (90°), nonintersecting shafts. Also, they are the smoothest, quietest type of gearing when properly applied.

How do Worm Gear Units Transmit Motion?

A worm gear arranged is a set 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.
