单列向心球轴承的振动和噪声是评定轴承动态性能的重要指标。随着我国机械工业产品质量的提高,特别是电机工业技术的发展,对轴承振动和噪声指标都提出了进一步的要求。为扩大外汇来源,机电产品出口的品种数量日益增多。为使我国出口的轴承产品能够打开销路,占稳市场,轴承噪声和轴承振动的水平至少必须与国外同类产品能够相提并论。为适应国内外的要求,进一步改善轴承的动态性能,降低轴承振动和轴承噪声,全国有关轴承厂(所)做了大量工作,已取得一定的成效。
Single row radial ball bearing vibration and noise is an important indicator of dynamic performance evaluation. With the improvement of the quality of China’s machinery industry products, especially the development of motor industry technology, bearing vibration and noise indicators have put forward further requirements. In order to expand the source of foreign exchange, the number of varieties of mechanical and electrical products exported is increasing day by day. In order to make our country’s exports of bearing products to open the market, accounting for steady market, bearing noise and bearing vibration levels must be comparable with similar foreign products at least. To meet the requirements at home and abroad, to further improve the dynamic performance of bearings and reduce bearing vibration and bearing noise, the relevant bearing plant (the) done a lot of work, has achieved some success.
