Изобретение относитс к области машиностроени , а именно к устройствам дл обнаружени повреждений подшипников качени .The invention relates to the field of engineering, namely to devices for detecting damage to rolling bearings.
Известно устройство дл обнаружени повреждений подшипников качени , содержаш;ее корпус и ротор, установленные с зазором дл размеш,ени в нем контролируемых подшипников, а также сигнальный механизм и датчик, закрепленный в корпусе A device for detecting damage to rolling bearings is known, having its housing and a rotor mounted with a gap for dispensing the controlled bearings therein, as well as a signal mechanism and a sensor fixed in the housing.
1.one.
Недостаток известного устройства состоит в запаздывании информапии о начале разрушени элементов подшипника.A disadvantage of the known device is the lag of information about the beginning of the destruction of the bearing elements.
Целью изобретени вл етс повышение точности обнаружени повреждений.The aim of the invention is to improve the accuracy of damage detection.
Указапна цель достигаетс тем, что устройство снабжено размеш,енной в зазоре между ротором и корпусом Z-образной поджимаюш ,ей втулкой, а сигнальный механизм встроен в Z-образную втулку со стороны датчика.Pointing to the goal is achieved by the fact that the device is equipped with a Z-shaped clamping in the gap between the rotor and the housing, pressing it with a sleeve, and the signal mechanism is integrated into the Z-shaped sleeve from the sensor side.
На чертеже изображено устройство, обш;ий вид.The drawing shows the device, general;
Устройство содержит корпус 1, ротор 2, контролируемые подшипники 3 и 4 и датчик 5, закрепленный в корпусе. В зазоре между корпусом 1 и ротором 2 размешена Z-образпа поджимаюша втулка 6 с встроенным в нее сигнальным механизмом 7 со стороны датчика 5.The device includes a housing 1, a rotor 2, controlled bearings 3 and 4 and a sensor 5 mounted in the housing. In the gap between the housing 1 and the rotor 2 there is a Z-obrazla podzhimayusha sleeve 6 with a built-in signal mechanism 7 from the sensor 5.
Устройство работает следующим образом.The device works as follows.
При врапхении ротора 2 Z-образна втулка 6 Браш,аетс с оборотами, близкими к половине оборотов ротора. Сигнальный механизм 7, проход при враш,ении перед датчиком 5, возбуждает сигнал, который усиливаетс и регистрируетс прибором.When the rotor 2 rappens, the Z-shaped sleeve 6 of the Brush comes with revolutions close to half the rotor revolutions. The signaling mechanism 7, the passage in vrasen, in front of sensor 5, excites a signal that is amplified and recorded by the instrument.
Увеличение трени в одном из подшипников изменит обороты втулки 6. Если трение увеличитс в подшипнике 3, обороты втулки возрастут и при его полной остановке будут равны оборотам ротора. Если трение увеличитс в подшипнике 4, обороты втулки 6 уменьшатс н при полной его остановке обороты втулки будут равны нулю.An increase in the friction in one of the bearings will change the turns of the sleeve 6. If the friction increases in the bearing 3, the turns of the sleeve will increase and, if it stops completely, will be equal to the turns of the rotor. If the friction increases in the bearing 4, the turns of the sleeve 6 will decrease when the bearing stops completely, the turns of the sleeve will be zero.
Таким образом, регистраци числа оборотов Z-образпой поджимаюшей втулки характеризует состо ние вращаюшихс подшипников качени .Thus, registration of the number of revolutions by a Z-type of a clamped sleeve characterizes the state of rotating rolling bearings.
