COVER GEAR HOUSING

A gear or cogwheel is a rotating machine part having cut teeth or, in the case of a cogwheel, inserted teeth (called cogs), which mesh with another toothed part to transmit torque. Geared devices can change the speed, torque, and direction of a power source. Gears almost always produce a change in torque, creating a mechanical advantage, through their gear ratio, and thus may be considered a simple machine. The teeth on the two meshing gears all have the same shape. Two or more meshing gears, working in a sequence, are called a gear train or a transmission. A gear can mesh with a linear toothed part, called a rack, producing translation instead of rotation.

A housing is a mechanical component's container or covering. In restaurant equipment, a housing is an exterior case or enclosure used to protect an interior mechanism, including integrated fittings or brackets to keep internal components in place. The housing prevents the interior mechanism from being fouled by outside debris or to contain the internal components.
