GEAR LEVER KNOB(BLUE) SHAFT

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.

In foodservice equipment, a knob may be as simple as a push button or "palm button". A control knob is a rotary control used to provide input to a device when grasped by an operator and turned, so that the degree of rotation corresponds to the desired input . Such knobs are one of the most common components in restaurant equipment control systems and are used to modulate a wide variety of settings such as temperature, viscosity, speed and more.

Levers are often used with foodservice equipment. For example, a lever is commonly found in beverage, condiment, and ice dispensing equipment where it is used to activate product flow. Coffee urns may use a lever to dispense coffee or hot water for tea. Most soda fountains use levers to dispense soda or other carbonated beverages. The lever is typically located on the front of the fountain and is pressed down to release the beverage into the cup. Two the simplest types of levers used in restaurants are a bottle or can opener which serve to pry off a cap, or punch a hole in a lid.
