Bearing failure occurred during operation is often the case, there is no need to fuss. There is fault, judgment and treatment is the key.
Institutional operation, installation of FAG bearings 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.
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); tapered roller bearing Assembly too tight; bearing washer on the shaft or in the shell rotation; load too large; bearing cages or FAG fragmentation, and so on.
1), shaft and hole of vertical degree of roundness and abutments to be in accordance with the FAG bearings the corresponding precision requirements.
2), precise calculation of rotating rings fit interference, also to precise calculation of the fixed amount of suitable tie rings. Rotating ring of burning of interference where possible should be made smaller. As long as the practical working temperature of thermal expansion affect, as well as the maximum speed under the influence of centrifugal force, does not cause tight fit only creeping or sliding on the surface. Fixed rings depending on work load size and bearing size, select minimal clearance fit or an interference fit, too loose or too tight is not conducive to precise shapes.
3), such as operation under high speed conditions of tapered roller bearing, and higher temperatures, should pay special attention to co-operation of rotating rings must not be too loose, to prevent the emergence of the eccentric vibration, as well as fixed rings combined with no gaps, in order to prevent fires ring deformation under load and vibration.
FAG bearings allowed light running noise at 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 of tapered roller bearing wear of mating surfaces. Since this kind of wear, damage bearings, FAG bearings and shaft and shell the cooperation relations, 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.
