Online monitoring skills of rolling bearings - fatigue magnetic alarm method This method monitors the working condition of bearings with smooth circulation oil supply method. It can be perceived that the minimum area is 0. 5mm2; the depth is about 0.1mm.
When the bearing is out of fatigue, the falling metal debris flows into the magnetic collecting device of the alarm device with the smooth oil. It is piled down together; due to the magnetic effect of the magnetic ring; the metal scrap is firmly sucked in the taper sleeve Inside the gap between the valve and the cone valve; the signal circuit is turned on in the gap via the metal chips; the light signal or the acoustic signal is declared to act as a fatigue alarm.
There is a tightening nut under the magnetic chip collector; the nut can be removed to remove the chip collector; to know the working condition of the bearing at any time; to view or replace the chip collector. When removing the chip collector; the upper shut-off valve is Under the effect of the spring, the matching taper surface of the large ring is pressed; the smooth oil is not; the leakage is caused; therefore, the dust collector can be replaced or viewed in the condition of no parking; or the bearing condition can be monitored.
