Research of Heterogeneous Type Piston Pin Boss Hole Closed Loop Processing System. 异型活塞销孔闭环加工系统研究;
The thick part of the piston that holds the piston pin is the pin boss. 用来支撑活塞销的活塞厚的部分称为活塞销凸台。
The main content of the thesis is as follows: 1 、 Summarize essence rules of piston pin boss configuration and pin bore surface design, including horizontal and vertical profile rules of pin bore, analyze and specify the definition method of pin bore fitting clearance. 总结了活塞销孔结构以及销孔表面设计的基本规律,包括销孔的横向形线规律和纵向形线规律两个方面,并分析说明了销孔配合间隙的确定方法。
