齿轮是机械工业中量大面广的基础件,由于齿轮工作条件不同,轮齿破坏的情况也不同,因此,在不同工况条件下,要选用不同性能的材料,施以相应的热处理,以发挥材料潜力,满足设计要求。随着我国四化建设的发展,产品上水平,上等级,对齿轮的质量要求也越来越高,而目前我国齿轮还存在着寿命短,精度低,噪声大等问题,这不但与齿轮的设计、加工、装配等因素有关,而且还和齿轮的材料及热处理质量有着密切的关系。本文就我国目前所用齿轮材料种类、齿轮材料质量和存在的问题及齿轮热处理质量概况分述如下。
Gear is a large part of the machinery industry, a wide range of basic parts, due to different gear conditions, tooth damage is also different, therefore, under different working conditions, to choose different properties of materials, heat treatment to be applied to Play material potential to meet design requirements. With the development of the four modernizations in our country, the products are on the level and the upper grades, and the quality requirements of the gears are also getting higher and higher. At present, the problems of short life, low precision and large noise in our gears still exist. Design, processing, assembly and other factors, but also with the gear material and the quality of heat treatment has a close relationship. In this paper, the current types of gear materials used in our country, the quality of gear materials and the existing problems and quality of gear heat treatment are described below.
