FAG bearing listening - bearing during operation

Check the status of the operation of the machine and prepare thoroughly check program has been more and more important, by over-packaging FAG bearing as the focus, because it is the most important of all the machines rotating parts, condition monitoring is an important part of the preventive maintenance, early detect the FAG bearing damage to avoid due to FAG bearing damage caused by the planned maintenance equipment during outage. Below I like to introduce you to listen to this method. Listening: using the hearing to identify irregular operation is a very common method, the examples use electronic stethoscope to check that a certain parts of abnormal noise was experienced operator use. FAG bearing if it is in good operation condition will be low purring sound, if a sharp hiss tone, make notes and other irregular sound, usually said FAG bearing in the operation condition of bad. High-pitched squeaky noise may be caused by improper lubrication. Improper FAG bearing clearance can cause metal sound. FAG bearing outer ring grooves on the tracks can cause vibration, and lead to sound like the coo of a smooth, if because of the installation caused by the striking scar also can produce noise, the noise will be along with the FAG bearing rotating speed of high and low. If there is intermittent noise, said rolling parts may be damaged, this voice is happens when the damaged surface is rolled out, FAG bearings if pollutants often causes hissing sound, FAG bearing damage will produce irregular and big noise. FAG bearing damage can be listening to check by sleep, but usually at this time has come to FAG bearing must be replaced immediately. Therefore, good methods such as using such as electronic condition monitoring instrument, the workings of the diagnostics FAG bearings in advance. Compared with old method ( Use a wooden stick or a screwdriver in FAG bearing box, the other end of the stick to the ear) , the use of advanced equipment more accurately forecast FAG bearing condition.
