Note: Because the efficiency of a worm equipment drive depends upon the lead position and number of begins 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 provides worm gears manufactured from a number of materials, such as acetal, minlon, bronze, and cast iron to fit 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. Since the pinion is definitely captivated axially, this rotation causes the worm wheel to rotate. The ratio of the worm established can be altered by changing the amount of tooth 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 transmission in applications requiring high-ratio speed reduction in a limited space using right position (90°), nonintersecting shafts. They are also the smoothest, quietest form of gearing when correctly applied.
Just how do Worm Gear Sets Transmit Motion?
A worm gear set is a set of gears comprising a worm (pinion) and a worm-wheel (worm gear), often used when a high ratio is required and space is limited.
