Gear housing

The gear housing is the casing that surrounds the mechanical components of a gear box. It provides mechanical support for the moving components, a mechanical protection from the outside world for those internal components, and a fluid-tight container to hold the lubricant that bathes those components.

Traditionally, it is made from cast iron or cast aluminium, using methods of permanent mold casting or shell molding. Experimentally, though, composite materials have also been used.
