发动机机体主油道滚压工艺研究

Study on Rolling Technology of Main Oil Gallery on the Engine Block

简要分析了某发动机机体主油道滚压技术要求和滚压过程中存在的主要问题及其对发动机造成的影响,并针对这些问题从滚压机转速、滚压力、滚压位置调节器、油管材料、油孔位置、机体主油道的加工质量等方面进行技术分析和工艺试验,最终得出机体主油道滚压的合理技术参数和工艺方法,使发动机机体主油道滚压过程中存在的问题得以解决。

The rolling technical requirements of main oil gallery on an engine boy, the main problems during the rolling process and their effects on engine were analyzed briefly, and were technically analyzed and technically tested for further considering the speed of rolling machine, the rolling pressure, the regulator of rolling location and the processing quality of main oil gallery. Accordingly, the reasonable technical parameters and technical methods of main oil gallery were acquired and the problems during the rolling process of main oil gallery were also resolved simultaneously.
