Description
мой 13, выход которой подключен к управл ющему входу измерител дисбаланса 9.my 13, the output of which is connected to the control input of the unbalance meter 9.
Устройство работает следующим образом .The device works as follows.
Сигнал с датчика дисбаланса 2 усиливаетс усилителем 8 и поступает на измерительный вход пикового детектора (измерител дисбаланса 9). При взаимодействии индуктивного датчика 11 с опорной точкой на валу 5 вырабатываетс сигнал, который поступает на вход формировател сигнала 12, с выхода которого пр моугольный импульс подаетс на вход стробирующей схемы 13, котора выдает восемь строб-импульсов, каждый из которых соответствует по времени перекладке определенного бича 7. В момент прихода строб-импульса на управл ющий вход измерител дисбаланса 9 происходит измерение амплитудного значени виброим ,пуса от датчика дисбаланса 2. Измерение амплитудного значени вибросигнала от каждого из восьми бичей 7 происходит поочередно, так как момент прохождени каждым бичом 7 датчика дисбаланса 2 зав зан по времени с поступлением на управл ющий вход измерител дисбаланса 9 соответствующего строб-импульса. Измеренное значение вибросигнала отмечаетс регистратором 10.The signal from the unbalance sensor 2 is amplified by the amplifier 8 and fed to the measuring input of the peak detector (unbalance meter 9). When an inductive sensor 11 interacts with a reference point on the shaft 5, a signal is generated, which is fed to the input of the signal conditioner 12, from the output of which a rectangular pulse is fed to the input of the strobe circuit 13, which produces eight strobe pulses, each of which corresponds to a time transfer 7. At the moment of arrival of the strobe pulse to the control input of the unbalance meter 9, the amplitude value of the vibration is measured, starting from the unbalance sensor 2. The amplitude value of the vibration signal is measured and from each of the eight pests 7 occurs alternately, as the passage time of each whip 7 imbalance sensor head 2 coupled with the arrival time to the control terminal imbalance meter 9 corresponding strobe. The measured value of the vibration signal is noted by the recorder 10.
Применение данного способа и устройства дл его реализации позвол ет значительно сократить врем на диагностирование молотильного барабана, своевременно вы витьThe use of this method and device for its implementation allows to significantly reduce the time for diagnosing the threshing drum, to find out in time
неисправность и устранить ее, что в свою очередь вызывает повышение производительности уборочной мащины.malfunction and eliminate it, which in turn causes an increase in the productivity of the harvesting machine.
