Note: Because the effectiveness of a worm equipment drive depends upon the lead angle and number of begins on the worm, the ratio should be kept low. To run correctly, worms and worm gears working together will need to 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 motion 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 arranged can be changed by changing the number of teeth on the wheel or changing the amount of begins on the pinion.
When used with EP Equipment worms, EP Gear’s worm gears provide effective power tranny in applications requiring high-ratio speed reduction in a restricted space using right position (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 arranged is a couple of gears comprising a worm (pinion) and a worm-wheel (worm gear), often used whenever a high ratio is required and space is limited.
For those whose enthusiasm is worm gear set, we have the solutions.
