Note: Because the performance of a 
worm gear 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 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 usually captivated axially, this rotation causes the worm wheel to rotate. The ratio of the worm set can be changed by changing the number of tooth on the wheel or changing the amount of starts on the pinion.
When used with EP Equipment worms, EP Gear’s worm gears provide effective power tranny in applications requiring high-ratio speed decrease 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 Pieces Transmit Motion?
A worm gear arranged is a set of gears consisting of a worm (pinion) and a worm-wheel (worm gear), often used whenever a high ratio is required and space is limited.
