摘　　要：提出在轴承滚道内注入纳米化学研磨剂对轴承摩擦副表面进行化学研磨处理。对研磨机理、研磨剂材料的选择和作用以及加工工艺进行了论述,对研磨前、后的轴承切片表面形貌进行多参数试验测试。结果表明,纳米化学研磨法能快速改善轴承滚道和滚动体的表面形貌,使轴承摩擦副表面获得优良摩擦学性能,降低噪声、减小振动值。A novel method was proposed to improve surface quality of bearing friction pair with nanometer grind technology. Using special nanometer material, mechanical grind and chemical abrasion were implemented at the same time. The grinding mechanism, characteristics of each grinding materials, and processing technology of new method were accounted in detail. With quantity of experiments on different kinds of bearings, measuring and analyzing surface morphology of friction pair, it is found that the chemical grinding method could effectively improve bearing＇ s surface morphology, reduce running vibration and noise, and increase hearing＇s quality.
