Institutional operation, install bearing parts allows a certain degree of temperature, when you touch body shell with your hand, should not feel hot to normal, whereas you FAG bearing temperature is too high.
Bearing high temperature causes are: quality does not meet the requirements or deterioration of lubricant, lubricant viscosity is too high; body fitted too tight (insufficient gap), FAG bearing Assembly too tight; bearing washer on the shaft or in the shell rotation; load too large; bearing cage effects of fragmentation, such as or.
FAG bearings allowed light running noise at work, if the sound is too loud or abnormal noise or impact sound, then bearing is faulty.
1, check the actual loads of FAG bearings and speed at variance with the original not gauge whether, bearing selection is correct;
2, to understand the damage and proximity to damage of abnormal phenomena, in particular the State and evolution of the emergence of situations such as noise and heat; attention to check the power supply and the bearing adjacent machine components during this time there is no anomaly. Analysis of noise type, high and low tone, rhythm of frequency interference: notice when the temperature suddenly increases, and so on, note the power supplies and the situation in other parts;
3, identify the host configuration and combined with characteristics of the bearing, whether or not configured properly, note the rings relative to the shell and position relative to the direction of load;
4, FAG bearings shaft with her hands together with corrupt try go few laps to experience running heavy levels, promoting several times back and forth along an axis to an axis to experience axis along the axial tension and, if necessary, measure the deflection of the shaft;
5, and check bearing is located parts, identified lubrication; situation and pollution situation, audit lubricant grades and sealed way whether wrong, attention in has temperature rose situation Shi, FAG bearing temperature whether over by with lubricant of temperature limited, focus check oil bit high and low, sealed gap whether leak oil leak fat, and water, and dust grain or other foreign body whether has intrusion bearing, for oil system has whether fault
6, to see whether the presence has an impact on bearing vibration sources. Debris or fluid or particle source, water pollution, flows through the bearing of current sources;
7, depending on circumstances, could serve as a basis to determine the bearing damage due to fretting corrosion, wear and tear, rust or corrosion is.
FAG bearings when removing checks, according to the bearing damage to determine causes of bearing failure and damage.
