近年来,我厂试用高铝锌基合金制造轴瓦、蜗轮等零件,收到很好效果。就这种材料的使用性能、加工工艺性能、成本以及货源来说,无疑是一种有前途的合金材料。 79年,我们将高铝锌基合金用于牛头刨床的轴套,这种轴套在转速不高、润滑良好的条件下工作。效果很好。82年将其用于石灰乳化皮带机蜗轮(m=6、Z=51、B=50),装机运转一年零三个月后,蜗轮单面磨损1～2mm,断了几个齿;而这种蜗轮采用生铁时,寿命只有3个月。83年底,将高铝锌基合金用于竖井稳轮衬套,据用户称:其使用寿命可
In recent years, our factory trial high aluminum-zinc-based alloy bearing bush, worm and other parts, received good results. The use of this material performance, processing technology performance, cost and supply, it is undoubtedly a promising alloy material. For 79 years, we have used high-aluminum-zinc-based alloys for bushings in shaper machines that work under conditions of low speed and good lubrication. good results. 82 years of its use for lime emulsifying belt machine worm (m = 6, Z = 51, B = 50), installed one year and three months after operation, the worm wear 1 ~ 2mm single-sided, broken a few teeth; This worm gear with pig iron, the life expectancy is only 3 months. By the end of 83, the high aluminum-zinc alloy shaft stabilizer bushing, according to the user: its service life can be
