What are Worm Gear Sets?
A worm gear set is a set of gears consisting of a worm (pinion) and a worm-wheel (worm gear), often used when a high ratio is required and space is limited.
How do Worm Gear Sets Transmit Motion?
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 captivated axially, this rotation causes the worm wheel to rotate. The ratio of the worm set can be altered by changing the number of teeth on the wheel or changing the number of starts on the pinion.
