本文介绍了用新型工程材料——铜钼锡蠕墨铸铁制造汽车发动机凸轮轴的试验研究情况。研究的结果指出,铜钼锡蠕墨铸铁高频淬火凸轮轴,在与15Cr钢渗碳淬火挺杆匹配时,其抗擦伤能力优于高频淬火的低合金球墨铸铁,普通蠕墨铸铁凸轮轴,特别是优于45钢(精选)高频淬火的凸轮轴;耐磨性优于45钢高频淬火凸轮轴,接触载荷下的持久性能相当或优于45钢高频淬火凸轮轴。铜钼锡蠕墨铸铁凸轮轴较易校直。铜钼锡蠕墨铸铁取代45钢制造凸轮轴,能延长使用寿命,降低成本,尤其适用于缺乏大型模锻设备的企业,有利于产品的更新换代。 This paper introduces the experimental research on the manufacture of automotive engine camshafts with a new engineering material, copper molybdenum-tin vermicular cast iron. The results of the study indicate that when the copper-molybdenum-tin vermicular graphite cast iron high-frequency quench camshafts are matched with the 15Cr steel carburizing quenched tappet, the anti-galling ability is better than that of the high-frequency quenched low-alloy ductile iron, ordinary vermicular graphite cast iron cam Shaft, especially better than 45 steel (Featured) high-frequency quenching camshaft; wear better than 45 steel high-frequency quenching camshaft, the durability of the contact load is equivalent to or better than 45 steel high-frequency quenching camshaft. Copper molybdenum tin vermicular cast iron camshaft easy to straighten. Copper molybdenum tin vermicular cast iron to replace 45 steel camshaft manufacturing, can extend the service life, reduce costs, especially for the lack of large forging equipment business, is conducive to product replacement.
