Transmission housing is a load-bearing part, which is generally made of die-casting aluminum alloy through special die-casting, with irregular and complex shape.

 The gearbox shell was mainly made of gray cast iron in the early stage, which has the advantages of easy forming, good shock absorption and low cost. With the improvement of users’ requirements for vehicle driving comfort and the maturity of lightweight technology, the gearbox shell on the car is replaced by aluminum alloy. The gearbox shell is mainly made of gray cast iron and aluminum alloy.

The transmission housing is a housing structure used to install the transmission mechanism and its accessories. In order to reduce the wear and power loss of parts caused by internal friction, lubricating oil must be injected into the shell and the working surfaces of gear pairs, shafts, bearings and other parts must be lubricated by splash lubrication. Therefore, there is an oil filler on one side of the shell, an oil drain plug at the bottom, and the oil level height is controlled by the position of the oil filler.

An oil seal assembly is installed in the rear bearing cover of the transmission. Install sealing gaskets at the joint surfaces of each bearing cover, rear cover, upper cover, front and rear housing, and apply sealant to prevent oil leakage. In order to prevent the leakage of lubricating oil caused by the increase of oil temperature and pressure during the operation of the transmission, a vent plug is installed on the transmission mechanism seat and the rear bearing cover of the transmission.

The main function of the gearbox shell is to support the transmission shafts, ensure the center distance and parallelism between the shafts, and ensure the correct installation of the gearbox shell parts and other connected parts. The processing quality of the gearbox shell directly affects the assembly accuracy and operation accuracy of the transmission assembly, as well as the working accuracy and service life of the vehicle, Therefore, the quality requirements are high.

Processing difficulties of gearbox housing:

1. There are many processing contents, and the machine tools and cutting tools need to be changed frequently.

2. The requirement of machining accuracy is high. It is difficult to guarantee the machining quality by using ordinary machine tools, and the process flow is long, the turnover times are many, and the production efficiency is difficult to improve.

 3. The shape is complex, and most of them are thin-walled shells, with poor workpiece stiffness, which is difficult to clamp.
