Bottom Shells of Gear-housing

The "bottom shells of gear-housing" typically refer to a component or part in the gear housing assembly of machinery and equipment. Gear housing encloses and protects the gears and other moving parts of a machine, such as a gearbox or transmission. The bottom shell is one of the components that make up the housing and provides structural support, protection, and often acts as a cover to prevent debris or contaminants from entering the gear system.
