Diesel engine rocker support

Materials, structure, and technology are the material and technical basis of product design. On the one hand, technology restricts design; on the other hand, technology also promotes design. From the point of view of design aesthetics, technology is not only the material foundation, but also has its own "functional" role. As long as it is good at applying the characteristics of materials, and corresponding structure forms and appropriate processing techniques, it can create practical, beautiful and economic Products, that is, the potential "functions" of technology in the product.

The designed part is the valve rocker shaft support of the rocker arm joint in the diesel engine. It is an important part of the valve control system on the L28 / 32A diesel engine accessory diesel engine. A hole with a diameter of 18mm is used to assemble the rocker shaft. One end of the shaft is installed with an inlet and exhaust valve rocker. A 16mm diameter hole is equipped with a pressure reducing shaft to reduce the pressure in the cylinder and facilitate starting the diesel engine. The distance between the two holes is 56mm, which can ensure that the decompression shaft opens the valve on the rocker arm to achieve decompression. The two holes require high surface roughness and position accuracy. They work in cooperation with the shaft to support the work. The hole with a diameter of 11 is connected to the cylinder head with a M10 screw, and the hole with a diameter of 3 is used to drain oil.
