本文系在活塞环的椭圆筒体加工研制的基础上,对活塞环的单体椭圆加工、正圆筒体加工、椭圆筒体加工等加工工艺进行比较,阐述各自的优缺点,说明椭圆筒体活塞环的优点。并对椭圆筒体活塞环的加工设备作一些简单的介绍。 一、研制椭圆筒体活塞环的目的和意义 活塞环生产,我国目前大致有以下两种典型工艺:一是筒体铸造,正圆加工的所谓筒体正圆环,即等压环;一是单体铸造,仿形加工的所谓单体椭圆环,即高点环。这两种工艺各有自己的优缺点,比较如下: Based on the development of the elliptical cylinder of the piston ring, this paper compares the machining process of single-ring piston, single cylinder, elliptical cylinder and so on, and elaborates the advantages and disadvantages of each. It shows that the elliptical cylinder Piston ring advantages. And the ellipse cylinder piston ring processing equipment for some simple introduction. First, the purpose and significance of the development of the piston cylinder piston ring Piston ring production, our current roughly the following two typical processes: First, the cylinder casting, machining is the so-called cylinder is the so-called ring, that is equal pressure ring; First Monomer casting, copying the so-called monolithic oval ring, that is, high point ring. These two processes have their own advantages and disadvantages, as follows:
