我们厂使用尼龙1010代替铜作轴套,用于低速部位,这种材料变形较少、耐压耐磨、容易加工、能保证导叶密合,这样不但节省了铜材,降低了成本,缩短了加工工时,还延长了轴套的使用寿命。因尼龙较软,在机械加工时,受刀具正压力后便会变形,加工不出圆的轴套。尼龙的膨胀系数比铁大近10倍,吸湿膨胀率也很大,如果加大厚度,温度、湿度一变化,装在机器上的尼龙轴套受外力作用向内膨胀而使内孔收缩抱轴。要解决此问题,只能把轴
Our factory uses nylon 1010 instead of copper for sleeve, for low-speed parts, the deformation of the material less, pressure wear, easy processing, to ensure guide vane close, so not only save the copper, reduce costs and shorten The processing time, but also extended the life of the sleeve. Due to the softer nylon, in machining, the tool will be deformed by the positive pressure, the processing of round bushings. Nylon expansion coefficient of nearly 10 times larger than the iron, hygroscopic expansion rate is also great, if you increase the thickness, temperature, humidity, a change in the nylon sleeve installed on the machine due to the expansion of the internal force so that the contraction of the inner shaft . To solve this problem, only the axis
