GASKET GEARCASE COVER

Gaskets are used in restaurant equipment to create a seal between two surfaces, such as between the door of a refrigerator and the frame or between two pieces of metal in a gas range. The gasket helps to prevent leaks of air or liquids, as well as to maintain a consistent temperature inside the equipment. Gaskets are often made of rubber or other flexible materials that can withstand heat and cold and maintain their shape over time. They are used in a wide variety of restaurant equipment, including refrigerators, freezers, ovens, and steam tables and are also commonly used in plumbing for equipment and sinks.

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 gearcase (gear case) is a casing for the gear mechanism of a piece of machinery. Similar in function to a chainguard, it is intended to prevent accidental contact with moving parts.
