Note: Because the performance of a worm gear drive depends upon the lead position and number of starts on the worm, the ratio should be kept low. To run properly, worms and worm gears operating together must have the same diametral pitch and threads.

EP Gear offers worm gears manufactured from a variety of materials, such as acetal, minlon, bronze, and cast iron to suit your application’s requirements.

The pinion meshes with the teeth of the worm gear at 90 degrees, and motion 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 starts on the pinion.
When used with EP Gear worms, EP Gear’s worm gears provide effective power transmitting in applications requiring high-ratio speed decrease in a restricted space using right position (90°), nonintersecting shafts. Also, they are the smoothest, quietest kind of gearing when properly applied.

Just how do Worm Gear Units Transmit Motion?

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