Description
Изобретение относитс к подшипниковой промышленности и может быть преимущественно использовано дл контрол состо ни пода1ипников качени .The invention relates to the bearing industry and can be advantageously used to control the status of rolling bearings.
Известен способ контрол состо ни подшипников качени , заключающийс в том, что измер ют вибрацию враЩсшицегос подшипника, производ т автонормирование величины сигнала вибрации , выдел ют из него амплитуды составл ющих в полосе информативных частот и определ ют состо ние подшипников по амплитудам и частотам выделенных составл ющих 1.A known method for monitoring the condition of rolling bearings, which measures the vibration of a rotating bearing, autorizes the magnitude of the vibration signal, extracts the amplitudes of the components in the information frequency band from it, and determines the condition of the bearings by the amplitudes and frequencies of the selected components. one.
Известно устройство дл контрол состо ни подшипников качени , содержащее последовательно соединенные вибропреобразователь, усилитель, блок автонормировани и блок частотных фильтров, блок аналогового пересчета, режимный переключатель, генератор, осредн ющую цепь, логарифмический преобразователь, индикатор, а также наушник, вход которого соединен со входом блока аналогового пересчета (11.A device for monitoring the condition of rolling bearings comprising a vibration transducer, an amplifier, an auto-regulation unit and a frequency filter unit, an analog conversion unit, a mode switch, a generator, an averaging circuit, a logarithmic converter, an indicator, and also an earphone, the input of which is connected to the input, are known. analog conversion unit (11.
Однако известные технические решени не позвол ют производить испытани различных типоразмеров подшипников .However, the known technical solutions do not allow testing of various sizes of bearings.
Цель изобретени - увеличение числа типоразмеров испытуемых подшипников .The purpose of the invention is to increase the number of sizes of tested bearings.
Поставленна цель достигаетс за счет того, что способ контрол состо ни подшипников качени заключа етс в том, что измер ют вибрацию вращающегос подшипника, производ т This goal is achieved due to the fact that the method of monitoring the state of rolling bearings consists in measuring the vibration of a rotating bearing, producing
10 автонормирование величины сигнала вибрации, выдел ют из него амплитуды составл ющих в полосе информатив-. ных частот, производ т выбор полосы измерительных частот, задаютс весовым коэффициентс и умножают ам15 плитуды составл ющих на заданный вегсовой коэффициент и определ ют состо ние подшипников по амплитудам и частотам полученных составл ю1дах.10 autonomalization of the magnitude of the vibration signal, the amplitudes of the components in the informative-band are extracted from it. frequencies, selects the measurement frequency band, sets the weighting factor and multiplies the amplitudes of the components by the specified coefficient and determines the state of the bearings by the amplitudes and frequencies of the components obtained.
