Frequently Asked Questions (FAQs)

1. What is the mechanical advantage of a worm gear?

The screw's mechanical advantage is the ratio of the distance traveled in one revolution to the force applied to its pitch. A worm gear uses the mechanical advantage of the ratio of plane length to height. When a screw is turned through one revolution, the screw advances the distance between successive threads.

2. What machines use worm gears?

Worm drives are used as the tuning mechanism for many musical instruments, including guitars, double basses, mandolins, bouzoukis, and many banjos (although most high-end banjos use planetary gears or friction pegs). A worm drive tuning device is called a machine head.

3. What is a worm gear and why are they used?

Worm gears are power-transmission components primarily used as high-ratio reductions to change the direction of shaft rotation and to decrease speed and increase torque between non-parallel rotating shafts. They are used on shafts with non-intersecting, perpendicular axes.
