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.

Methods of manufacture

Traditionally, it is made from cast iron or cast aluminium, using methods of permanent mold casting[1] or shell molding.[2] Experimentally, though, composite materials have also been used.[3]
