摘要
分析了摩擦压力机主螺母受力情况,确定了使用性能指标,并成功地研制了一种锌合金主螺母材料。其耐磨性优于ZQAl9-4、ZQSn6-6-3。在使用过程中尺寸稳定性和冲击疲劳性能良好。使用寿命和铜合金相比提高1倍以上,可取得明显的经济效益和社会效益。
In this paper, the force imposed on guide nut of rubbing-supressing machine is analyzed and a new kind of zinc-based alloy for guide nuts is investigated. The wear resistance of this new material is superior to ZQA1 9-4 and ZQSn 6-6-3. Its size-stability and impact fatigue property are also excellent. The service life of zinc-besed alloy is one more time longer than that of copper-based alloy.
