The aim of the invention is to increase the efficiency of diagnosing the technical condition of a bearing assembly. The goal is achieved by measuring the time of a signal proportional to the vibration, from half the amplitude to the maximum and from zero to half the amplitude. In relation to the measured values, the condition of the bearing assembly is judged. (/ С N3 SO OD SP e 00
Description
Изобретение относитс к вибродиагностике и может быть использовано дл определени технического состо ни подшипниковых узлов асинхронного двигател с подшипниками качени .The invention relates to vibration diagnostics and can be used to determine the technical condition of the bearing units of an induction motor with rolling bearings.
Целью изобретени вл етс повышение эффективности диагностики технического состо ни подшипникового узла.The aim of the invention is to increase the efficiency of diagnosing the technical condition of a bearing assembly.
Способ диагностики подшипниковых узлов заключаетс в следуюш,ем.A method for diagnosing bearing assemblies is as follows.
Измер ют врем нахождени вибросигнала при изменении амплитуды от половины ее значени до максимума на определенном интервале наблюдени . Измер ют врем нахождени вибросигнала от нул до половины значени амплитуды на том же интервале наблюдени , рассчитывают отношение этих времен и при величине послед1293528The time of a vibrosignal is measured when the amplitude changes from half of its value to a maximum at a certain observation interval. The time of the vibration signal from zero to half of the amplitude value is measured at the same observation interval, the ratio of these times is calculated also at the last 12353528
него более 0,3 считают, что подшипник имеет повреждение.more than 0.3 it is considered that the bearing is damaged.
Величина диагностического параметра определена экспериментальным путем.The value of the diagnostic parameter is determined experimentally.
