Monitoring the working state of rolling bearing

By using the magnetic plug method for rolling bearing 1 stop monitoring. Using the magnetic plug to request (stop monitoring of the rolling element bearing 1) Magnetic plug only applies to oil is smooth, and after a special pipeline oil return key stop monitoring main bearing. （ 2) The magnetic plug to the device is in the monitoring of the main bearing full, is situated on the main in the oil return, no filter, oil pump and other hydraulic parts cut off. （ 3) In order to progress monitoring efficiency, able to make a return oil import and export of spiral type fuel reservoir. Pour a cone shape of fuel reservoir shall be prepared, the magnetic plug device at the bottom of the oil container. Oil container inlet to tilt Angle, can make smooth oil by tangential to enter it. This is beneficial to the wear of abrasive and circle smooth oil separation, and precipitation in the bottom, through the holes into the magnetic plug, adsorption in magnetic steel end. 2. Under normal conditions the morphological characteristics of rolling bearing wear grits in the running-in period and normal operation period, produced by the grinding grain fragments size ordinary to 0. 01 ~ 0. 015 mm, and mixed with some metal powder. New bearing in the running-in period the number of pieces of grits than normal running period, abrasive debris into the normal operation period, and can significantly reduce the number of metal powder. Abrasive debris under the microscope to present the appearance of fine, short, with irregular cross section. 3. Wrong with sex of morphological characteristics of rolling bearing wear grits main failure mode is the fatigue pitting. Rolling fatigue, peeling off pieces of grits size ordinary to 0. 025-0. 05mm。 Sometimes a size larger pieces, and mixed with some metal powder. Ball bearing steel ball grinding grain usually roughly circular pieces, along the radial separate way of rose petals; Raceway grinding grain of broken fragments appear roughly circular appearance; Roller bearing roller grinding grain fragments usually present length is equal to 2 ~ 3 times the width of curly rectangular way; Raceway grinding grain of irregular rectangular pieces of ordinary. With temperature measurement method for rolling bearing stop monitoring problems that should pay attention to after the temperature rise in measurement of bearing operation condition, ordinary hard to monitoring of rolling bearing fatigue spalling, crack or indentation part damage, especially in the early stages of the damage is impossible to find what's the problem. After running for a long time, when the bearing temperature increase phenomenon, common problems reflected by not only once, and will rapidly develop, the formation damage of bearing fault. This time, the continuous monitoring will often form the leakage situation. If found in monitoring the temperature of the bearing beyond 70 ~ 80 ℃, it is necessary to stop the machine immediately to check. About the new device or a heavy adjustment of rolling bearing, through temperature measurement method to monitoring the temperature rise in the rules of time, can distinguish bearing device and adjust the quality, special clearance too tight will appear the phenomenon of temperature rise too high. Found that the problem timely adjustment, is helpful to prolong the using life of rolling bearings.
