摘要
本文借助电子扫描透镜(TEM)和X-射线衍射仪(XRD)对油溶性纳米铜颗粒进行了物相分析,通过四球试验机钢-钢摩擦副确定了纳米铜颗粒作为N32润滑油添加剂的最佳添加量,并比较了含有纳米铜最佳添加量的N32基础油和纯N32基础油润滑条件下电主轴的噪声、振动速度有效值和温升值.结果表明:纳米铜添加质量分数为0.5%时,摩擦系数和磨斑直径最小,且电主轴产生的噪音、振动速度有效值和温升值低于同一转速下使用纯N32基础油的结果.
Based on experiments,the structure of Cu nanoparticles was characterized by transmission electronmicroscopy(TEM)and X-ray powder diffraction(XRD).The friction and wear tests of steel-steel tribo-pair lubrticated by oil with and without nano-Cu particles were counducted on a four ball tribo-tester for optimized concentration of nano-Cu particles.Comparisons on vibration,noise and temperature rise of motorized spindle were also included..The results showed that the optimized concentration of Cu nanoparticle for the best tribological performance was 0.5%.Vibration,noise and temperature rise of motorized spindle with 0.5% Cu nanoparticle N32 as additive in oil were lower than that lubricated by pure N32 oil.
