#WORM WHEEL SHAFT

A shaft is a rotating machine element, usually circular in cross section, which is used to transmit power from one part to another, or from a machine which produces power to a machine which absorbs power. The various members such as pulleys and gears are mounted on it.

Worm drives are commonly used in commercial foodservice mixing equipment. A worm drive or worm assembly is a gear arrangement in which a worm (which is a gear in the form of a screw) meshes with a worm gear (which is similar in appearance to a spur gear). The two elements are also called the worm screw and worm wheel which accommodate a directional transfer of energy. Like other gear arrangements, a worm drive can reduce rotational speed or transmit higher torque. A worm is an example of a screw, one of the "six simple machines". One of the major advantages of worm gear drive units are that they can transfer motion in 90 degrees.
