FEEDWORM W/SPRING

A spring is an elastic object that stores mechanical energy. Springs are typically made of spring steel. There are many spring designs. In everyday use, the term often refers to coil springs. When a conventional spring, without stiffness variability features, is compressed or stretched from its resting position, it exerts an opposing force approximately proportional to its change in length.

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.
