Description
ной частотой пропускани . Частоту пропускани фильтра выбирают в диапазоне вынужденных колебаний подшипника.transmission frequency. The frequency of the filter pass is chosen in the range of forced oscillations of the bearing.
Выключают привод и на выбеге подшипника при уменьшении частот основных спектральных составл юш,их и последовательном их совпадении с посто нной частотой пропускани фильтра измер ют частоту вран1ени и амплитудный спектр вибраций подшипника, например, с помон1,ью двухкоординатного самописца, подава на его вход (ось ординат) сигнал с узкополосного фильтра, а на выход (ось абсцисс)-сигнал , пропорциональный частоте враш,ени подшипника.The drive is switched off and on coasting of the bearing with decreasing frequencies of the main spectral components, and consistently coinciding with a constant filter transmission frequency, the frequency of the lying and the amplitude spectrum of the bearing vibrations are measured, for example, with a two-coordinate recorder, fed to its input the ordinate is the signal from the narrow-band filter, and the output (abscissa axis) is the signal proportional to the frequency of the turn, of the bearing.
В св зи с тем, что измеренные таким образом спектральные составл юпдие вибраций приведены к одной частоте, равной частоте пропускани фильтра, то соотношение их амплитуд будет характеризовать в одном масштабе соотношение величин имеюшихс в подшипнике дефектов. Вид дефектов , имеюпдихс в подшипнике, определ ют по частоте враш,ени подшипника в моменты прохождени спектральными составл юш ,ими частоты фильтра.Since the spectral components of vibrations measured in this way are reduced to one frequency equal to the filter transmission frequency, the ratio of their amplitudes will characterize on a single scale the ratio of the values of defects in the bearing. The type of defects, having a bearing in a bearing, is determined by the frequency of the bearing, the bearing at the moments of passing through the spectral components, the filter frequencies.
