摘要
内燃机是许多机械的重要动力来源,它的结构及工作原理导致了其工作环境的严苛,而活塞环正好是极端高温的直接接触部件,因此对其使用性能要求较高。现代内燃机的发展方向是高速度、高效能、大功率,对此有必要对活塞环的使用性能做进一步研究改进,以适应其新的工作环境。本文对活塞环的外形、材料和表面处理等制造方面的技术重要研究点进行了阐述,并分析了其优缺点,对未来活塞环制造技术的提供了思路。
The internal combustion engine is an important power source of many machines, it is the structure and working principle that lead to its harsh working environment, and piston ring is just the direct contact parts of extreme high temperature, so it requires higher performance. The development direction of modern internal combustion engine is high speed, high efficiency and high power. In this paper, the important research points of piston ring manufacturing technologies, such as shape, material and surface treatment, are described, and its advantages and disadvantages are analyzed.
