当前,所使用的轴承合金种类很多,它们各有优缺点,完美无缺的东西是没有的。通常,轴承合金的好坏由下列几项决定:①湿润性②冲击刚性③可塑性④坚韧性⑤耐磨性⑥耐烧伤性⑦摩擦系数⑧耐蚀性等。因此,它们与轴的材料有关。即使轴承磨损小,轴的磨损大,也意味着不好。同时,产品的成本也是重要的问题。本文对最常用的各种轴承合金,从润滑这个角度作一叙述。 Currently, there are many types of bearing alloys used, each with its own advantages and disadvantages, and nothing perfect. Usually, the quality of the bearing alloy is determined by the following items: ① wetting ② impact rigidity ③ plasticity ④ toughness ⑤ wear resistance ⑥ burn resistance ⑦ friction coefficient ⑧ corrosion resistance and so on. Therefore, they are related to the material of the shaft. Even small bearing wear, shaft wear large, but also means bad. At the same time, the cost of the product is also an important issue. This article describes the most commonly used bearing alloys from the lubrication point of view.
