What is the worm gear used for?

The worm and worm gear, which are illustrated in Figure 57.21, are used to transmit motion and power when a high-ratio speed reduction is required. They accommodate a wide range of speed ratios (60:1 and higher can be obtained from a single reduction and can go as high as 500:1).

What are worm gears examples?

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.

Why is it called a worm gear?

The reason why the worm gear is called a worm gear is derived from bionics. ... Worm gear mechanisms are commonly used to transmit motion and power between two staggered shafts. The worm gear and the worm are equivalent to the gear and the rack in the middle plane, and the worm is similar in shape to the screw.

How does a worm gear work?

How Do Worm Gears Operate? Worm gears operate by the friction created by turning lubricated gears. The friction is then converted into heat. By producing a low speed and high-speed torque level, worm gears are utilised as speed reducers, which implies that they are ideal for several applications.
