Note: Because the effectiveness of a worm equipment drive depends upon the lead position and number of starts on the worm, the ratio should be kept low. To perform correctly, worms and worm gears operating together must have the same diametral pitch and threads.
EP Gear offers worm gears manufactured from a number 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 movement 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 established can be changed by changing the amount of tooth on the wheel or changing the amount of starts on the pinion.
When used in combination 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. They are also the smoothest, quietest kind of gearing when properly applied.
How do Worm Gear Sets Transmit Motion?
A worm gear established is a couple of gears comprising a worm (pinion) and a worm-wheel (worm gear), often used when a high ratio is required and space is bound.
