Note: Because the performance of a worm equipment drive depends on the lead position and number of begins on the worm, the ratio should 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 variety of materials, such as for example 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 can be captivated axially, this rotation causes the worm wheel to rotate. The ratio of the worm set can be modified by changing the amount of the teeth on the wheel or changing the amount of starts on the pinion.
When used with EP Gear worms, EP Gear’s worm gears provide effective power transmission in applications requiring high-ratio speed reduction in a limited space using right angle (90°), nonintersecting shafts. They are also the smoothest, quietest type of gearing when properly applied.
How do Worm Gear Models Transmit Motion?
A worm gear set is a set of gears comprising a worm (pinion) and a worm-wheel (worm gear), often used whenever a high ratio is required and space is bound.
