FAG bearing failure in the operation of the process is often the case, so no big deal. Malfunction, to judge and deal with is the key. Today we explain FAG Bearings common failures and excluded. Needle bearing temperature causes: the quality of lubricating oil does not meet the requirements or deterioration, lubricant viscosity is too high; institutions assembly tight (gap); bearing assembly too tight; bearing ring rotation on the shaft or shell; The load is too large; bearing cage or rolling body fragmentation.
Cause the axis to deviate from the correct position, abnormal sound in the high-speed movement of the shaft. When the bearing fatigue, the surface metal peeling, but also make the FAG bearing radial clearance increases to generate abnormal sound. In addition, the needle bearing lubrication, the formation of dry friction, and bearing broken and will produce an unusual sound. Bearing wear Songkuang cage loose damage, also have abnormal noise bearing damage.
And bearing manufacturing-related noise: included here to keep aircraft noise and vibrato, cage noise occurs mainly in the ball bearings and FAG bearings, sound, collision due to vibration cage and cage and rolling element bearing swivel This sound has a periodicity. vibrato (all kinds of bearings) is a certain frequency of sound, is due to the raceway surface of the larger waviness caused by vibration generated this phenomenon is the most common problem, we later need a lot of attention before. In particular, we are learning some knowledge of students who are needle roller bearings, a closer look at these critical content, and may find you have some help.
Second improper use caused by noise: there are all kinds of bearing FAG bearing raceway surface or rolling surface by the bumps, the pressure pit, corrosion, it will produce a certain period of noise and vibration when the bearing in operation dust intrusion will produce dirt, noise, noise is non-cyclical, also accompanied by vibration, the sound is not fixed in size, from time to time.
Third inherent noise: the raceway sound with a variety of bearings and rolling friction sound Rolling inherent in the sound, the raceways sound is generated by the elastic properties of the rolling element and raceway contact, when the FAG bearing swivel, rolling in the rolling trail; normal rolling friction sound may issue a "creak, creak" uncomfortable abnormal noise of metal friction rolling issued in a continuous and smooth the sound, well-oiled does not issue such a sound, so in general not a problem, need to pay attention only after the increase of the noise.
FAG bearing raceway and the roller contact surface uneven pits, indicating that the bearing of the plastic deformation. The reason is that the bearings in a large static load or impact loads, the working surface of the local stress exceeds the material yield limit, this situation generally occurs in low-speed rotation of the needle bearing. Cause of Crack bearing ring may be FAG Bearings with tight bearing foreign or inner ring loose, inclusive deformation bearing, installation bearing surface processing bad.
Through the above analysis, now we all understand and know how to deal with the problem by the noise of FAG Bearings it. Finally, would like to use FAG bearings can be worry-free operation.
