Note: Because the efficiency of a worm equipment drive depends on the lead position and number of starts on the worm, the ratio should be kept low. To run properly, worms and worm gears working together must have the same diametral pitch and threads.
EP Gear provides worm gears manufactured from a variety 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. Since 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 number of teeth on the wheel or changing the number of starts on the pinion.
When used in combination with EP Equipment worms, EP Gear’s worm gears provide effective power transmitting in applications requiring high-ratio speed decrease in a limited space using right angle (90°), nonintersecting shafts. Also, they are the smoothest, quietest form of gearing when properly applied.
How do Worm Gear Sets Transmit Motion?
A worm gear arranged is a set of gears consisting of a worm (pinion) and a worm-wheel (worm equipment), often used when a high ratio is required and space is bound.
