The differential housing is the core support component of the differential, primarily used to hold the internal gear set and withstand the torque and load during transmission. It is typically made of high-strength cast steel or aluminum alloy and manufactured through precision milling, drilling, and heat treatment processes to ensure structural rigidity and dimensional accuracy. The differential housing not only ensures stable gear meshing but also provides support for long-term reliable operation of the differential, while accommodating high-load and high-speed conditions in various automotive and industrial transmission systems.
