FAG bearings of a rotation, the inner ring and outer ring raceway, due to contact with the roller is rolling, so are the track to the dark side, the track does not belong to the exception on the Raceway, which could be relevant to load conditions, so in the case of removing bearings, please pay special attention and observation of Raceway surface running track.
If you look closely at the track, you will learn that only burdens radial loads, bear large axial loads, moments of endurance load, or extreme rigidity on bearing boxes are not equal.
Can check the bearing is combined with an unexpected load and install error state, and became a holding loss for clues to the cause of the bearing.
If you do not select errors and correctly used, prior to the FAG bearing life, but for a long time, in this case, the damage to split. The other hand, there are early injury by accident, and stand up to use an early injury, as the reason for the early damage, use and consider enough lubrication, and thus there are foreign bodies penetrated, and large deflections of the shafts, the bearing Assembly error insufficient study of the shaft and housing.
It can be said that these reasons coincide with each other more. Therefore, machines to be used in full knowledge of FAG bearings, used condition, bearing the perimeter of the structure on the basis of, if we can clarify the situation before and after the accident, combined with injury of deep groove ball bearings and visit a variety of reasons, you can prevent the recurrence of similar incidents.
FAG bearings fault is generally of two types, one bearing mount temperature is too high, the second is a bearing noise in operation.
1. bearing temperature too high
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, instead it indicates that the bearing temperature is too high.
FAG bearings overheating causes are: quality does not meet the requirements or deterioration of lubricant, lubricant viscosity is too high; body fitted too tight (insufficient gap); bearing Assembly too tight; bearing washer on the shaft or in the shell rotation; load too large; deep groove ball bearing cages or fragmentation, and so on.
2. bearing noise
Bearing in the minor operation noise is allowed in the work, if the sound is too loud or abnormal noise or impact sound, then bearing is faulty.
FAG bearing the causes of noise are more complex, one is the inner and outer rings mating surfaces of the bearing wear. Because of this wear, damaged bearing shells, bearing and shaft fit, causes the axis deviates from the correct location, noise resulting from the axis in high-speed motion. When you are bearing fatigue, its surface metal flake, also bearing radial clearance increases the noise. In addition, insufficient lubrication of the bearing, the formation of dry friction, as well as deep groove ball bearing crush produces abnormal noises. FAG bearing wear after loose, loose cage damage, would also have abnormal noise.
