Note: Because the effectiveness of a worm gear drive depends upon the lead position and number of starts on the worm, the ratio ought to be kept low. To perform properly, worms and worm gears working together will need to 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 fit 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 is captivated axially, this rotation causes the worm wheel to rotate. The ratio of the worm arranged can be modified by changing the number of tooth on the wheel or changing the amount of begins on the pinion.
When used in combination 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 angle (90°), nonintersecting shafts. Also, they are the smoothest, quietest form of gearing when properly applied.
Just how do Worm Gear Pieces Transmit Motion?
A worm gear set 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 bound.
