Description
(54) УСТРОЙСТВО ДЛЯ ОПРЕДЕЛЕНИЯ ВРЕМЕНИ ОКОНЧАНИЯ ПРИРАБОТКИ ПАРЫ ТРЕНИЯ(54) DEVICE FOR DETERMINING THE TIME FOR ENDING THE WORKING OF A FRICTION PAIR
1one
Изобретение относитс к испытатегшной технике и может быть использовано при не разрушающем контроле процесса трени в подшипниковых узпах в машиностроении .The invention relates to a testing technique and can be used for non-destructive control of the friction process in bearing units in mechanical engineering.
Известно устройство дл определени времени окончани приработки пары трени , содержащее последовательно электрически соединенные датчик акустической эмиссии, предусипитель, усилитель, счет-,Q чик сигналов и блок сравнени . Работа этого устройства основана на регистрации эмиссии акустических волн напр жений с поверхности трени по их суммарной интенсивности и скорости нараста- 15 ни Ij ,A device is known for determining the end time of running-in of a pair of friction, which contains a series of electrically connected acoustic emission sensors, a preamplifier, an amplifier, a counting, a Q signal ticker, and a comparison unit. The operation of this device is based on recording the emission of acoustic stress waves from the surface of the friction by their total intensity and speed of growth - 15 and Ij,
Недостатком этого устройства вл етс невысока точность определени времени окончани приработки пары трени ,что го обусловлено тем, что оно может выдать ошибочный сигнап об окончании приработки из-за нестационарности нарастани иccии ВОПИ Напр жений,The disadvantage of this device is the low accuracy of determining the time of completion of the running-in of a pair of friction, which is due to the fact that it can give an erroneous signal about the end of the running-in due to the nonstationarity of the increase in WIPS voltage,
Цель изобретени - повышение точности определени времени окончани приработки пары трени .The purpose of the invention is to improve the accuracy of determining the time of completion of the running-in of a pair of friction.
Поставленна цепь достигаетс тем, что устройство снабжено вторым счетчиком сигналов, включенным параллельно первому, двум оперативно запоминающими блоками, соединенными соответственно с первым и вторым счетчиками, электронным ключом, включенным между усилителем и счетчиками и блоком управлени , выход которого св зан с входом электронного ключа.The delivered circuit is achieved in that the device is equipped with a second signal counter connected in parallel with the first, two operative storage units connected respectively to the first and second counters, an electronic key connected between the amplifier and the counters and the control unit whose output is connected to the input of the electronic key.
На чертеже представлена блок-схема устройства.The drawing shows the block diagram of the device.
Устройство содержит датчик 1 акустической эмиссии, предусилитель 2, усилитель 3, электронный ключ 4, счетчики 5 и 6 сигналов, включающие в себ одновременно и оперативно запоминающие блоки (не показаны), блок 7 сравнени и блок 8 управлени .The device comprises an acoustic emission sensor 1, a preamplifier 2, an amplifier 3, an electronic switch 4, counters 5 and 6 signals, which simultaneously and operatively store blocks (not shown), a comparison unit 7 and a control unit 8.
Устройство работает следующим образом .The device works as follows.
