worm gear set

Note: Because the performance of a worm equipment drive depends upon the lead position and number of begins on the worm, the ratio ought to be kept low. To run correctly, worms and worm gears working 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 fit your application’s requirements.

The pinion meshes with the 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 certainly captivated axially, this rotation causes the worm wheel to rotate. The ratio of the worm set can be changed by changing the amount of the teeth 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 transmitting in applications requiring high-ratio speed reduction in a restricted 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 established is a couple of gears consisting of a worm (pinion) and a worm-wheel (worm gear), often used when a high ratio is necessary and space is bound.
