以实验为基础，研究了6203-2RZ轴承振动与噪声的关系。振动包括加速度有效值和速度有效值，噪声指声压级。数据处理结果表明，轴承振动与噪声的统计关系不明显。因此，不宜用轴承的振动代替轴承的噪声，应单独研究轴承的噪声问题，制定轴承噪声标准和相应的工艺标准。

Based on experimentation, the relationship between the vibration and the noise of rolling bearings is studied. A type of rolling bearing, 6203 - 2RZ, is used in experimentation. The vibration includes the virtual values of the acceleration and the velocity, and the noise refers to the sound-pressure-level. The experiment data are comprehensively processed in the light of the theory of mathematical statistics. According to the results of data processing，the relationship between the vibration and the noise of rolling bearings is not definite. Therefore, the vibration can not represent the noise. The problem of the noise of rolling bearings should be studied independently, the standard of the noise and the corresponding technological specification of the rolling bearings should be established.
