1　引言目前 ,随着轴承工业的发展 ,与之相配套的轴承防锈油生产业也迅速发展起来 ,防锈油的发展状况基本上与轴承发展相适应。但目前存在着一个困扰轴承行业的难题 ,即一些小型电机轴承涂油后噪音值稳定性问题。按国家标准 ,Ｚ4、Ｚ5 组轴承经过煤油清洗后的噪音值摆动在 1分 1 Introduction At present, with the development of the bearing industry, and its accompanying anti-rust oil bearing industry has also developed rapidly, the development of anti-rust oil is basically compatible with the development of bearings. But now there is a problem that plagues the bearing industry, that is, some small motor bearing oil stability problems after the noise. According to national standards, Z4, Z5 bearings after kerosene noise after the value of the swing in 1 minute
