A container for gear sets that transmit power from one rotating shaft to another. A gear box is designed to precisely control gear and shaft alignment, provide a container for the gear oil, and to protect the gears and lubricant from water, dust, and other environmental contaminants. Gear boxes are utilized in a wide range of industrial, automotive, and home machinery. Not all gears are enclosed in gear boxes however: some gears are open to the environment and are lubricated by highly adhesive greases.
