Development of higher-performance aeronautical gear steel
-
摘要: 评述了国内外高性能航空齿轮钢的研究与发展状况。齿轮钢经历了由高硬度、常温使用进而高硬度、中温使用到超高硬度、高韧性、耐腐蚀、高温使用三代发展。发展高性能齿轮钢、高纯熔炼和先进的相关设计、加工技术是达到高承载、长寿命齿轮的必由之路。Abstract: The current status of development of high performance aeronautical gear steel has been evaluated.Three generation gear steels,including high hardness steel used at conventional temperature,high hardness steel used at medium temperature and the steel which possesses ultra high hardness in case,ultrahigh strength with excellent toughness in core,corrosion resistance used at high temperature have been developed.It is the best way to obtain high power density and long life gear to develop higher-performance gear steel, superpure melted and advanced relative technique,such as design,manufacture,heat treatment of gear.
