COUPLING AUGERMOTOR

A screw conveyor or auger conveyor is a mechanism that uses a rotating helical screw blade, called a "flighting", usually within a tube, to move liquid or granular materials. Screw conveyors in modern restaurant equipment are often used horizontally or at a slight incline as an efficient way to move semi-solid materials, including food, ice, waste, wood chips, cereal grains, meat, and many others.

A coupling is a device used to connect two shafts together at their ends for the purpose of transmitting power. The primary purpose of couplings is to join two pieces of rotating equipment while permitting some degree of misalignment or end movement or both. In a more general context, a coupling can also be a mechanical device that serves to connect the ends of adjacent parts or objects. Couplings do not normally allow disconnection of shafts during operation, however there are torque limiting couplings which can slip or disconnect when some torque limit is exceeded. Selection, installation and maintenance of couplings can lead to reduced maintenance time and maintenance cost.

Alternatively, in plumbing or with tubing a coupling connects two pipes. If their sizes differ, the fitting is known as a reducing coupling, reducer, or an adapter. There are two types of couplings: "regular" and "slip". A regular coupling has a small ridge or stop internally, to prevent over-insertion of a pipe, and thus under-insertion of the other pipe segment (which would result in an unreliable connection). A slip coupling (sometimes also called a repair coupling) is deliberately made without this internal stop, to allow it to be slipped into place in tight locations, such as the repair of a pipe that has a small leak due to corrosion or freeze bursting, or which had to be cut temporarily for some reason.

Motors are used in all kinds of foodservice equipment to power beaters, blenders, slicers, basket lifts, filters, fans and much more. A motor converts one form of energy into mechanical energy. General-purpose motor designs with standard dimensions and characteristics provide convenient mechanical power for foodservice equipment once customized to the exact OEM specifications (RPM, torque, magnet dimension, winding, etc.).

Different types of motors are used in restaurant equipment, including AC motors, DC motors, and stepper motors. AC motors are used to power equipment that requires high torque, such as mixers, grinders and ice machines. DC motors are used in equipment that requires precise control, such as conveyor belts and automated food prep machines. Stepper motors are used in equipment that requires precise positioning, such as robot arms and automated food dispensers.
