摘　　要：轴承运转中的异常声音是国产微型轴承的重要质量问题。认为轴承异音是一种瞬态脉冲，可以用时频谱图加以描述。在异音试验测试的基础上，提出了轴承异音的评估参数，并得出初步的统计结果。The abnormal noise produced in the course of the runniny of rolling bearing is a serious quality problem of the miniature rolling bearing made in our country. It is put forward that the abnormal noise of the bearing is a kind of transient pulses which can be illustrated by the time-frequency spectrogram. The parameters for evaluation of the abnormal noise of the rolling bearing are brought forward, which are based on the measurement and tests of the abnormal noise. At the same time, the preliminary statistics results are obtained.
