Many reasons for failure, all influencing factors of design and manufacturing processes are associated with SKF bearings failure analysis is difficult to judge. In normal circumstances, generally can be used from both factors and internal factors to consider and analyse.
Use factors mainly refer to installation and adjustment, maintenance, compliance with the technical requirements, such as maintenance and repair. Installation conditions is one of the leading factors in the use factors, bearing is often caused by the installation is not the right set of stress change of bearing parts, bearings running in an abnormal state and early failure. According to bearing technical requirements for installation, use, maintenance, maintenance, operation FAG bearings the burden of load, speed, temperature, vibration, noise monitoring and checks and lubrication, unusual now to find reasons to adjust, bring it back to normal. In addition, the grease quality and the surrounding medium, atmosphere analysis test is also important.
1, axle bearing installation location is not correct, can cause large ball end and bearing inner race and outer race retaining axial force, cause bearing overheating.
2, use the bearing selection the best requirements of accuracy of bearing.
3, the use of bent or plane bearing spindle box hole concentric cause heating solution is fixed spindle
4, bearing belt too tight causing the heating of the solution is to adjust the belt tension properly.
5, resolution of fever caused by poor lubrication method is to use code designation of lubricating materials and proper cleaning.
6 cause fever, low Assembly quality of the solution is to improve the quality of Assembly.
7, plane bearing shell running in circles causing heating solution is to replace the NSK bearings and related wear parts correct balancing of the impeller diameter and verify static balance values
8, caused by too much axial heating solution is cleaning, adjustment of the sealing mouth ring clearance requirements
9, rolling bearing damage caused fever's solution is to replace the flat housing. When we use the bearings when
Bearing roller bearing Raceway is and how it is measured when the vehicle is running, its move is moving on the surface of the Raceway and a kind of slippery sound, bearing seal what type?. Is the foundation of cities without moving bearing no sound. TIMKEN bearings Raceway sound with other sounds. Ball bearing roller is not law, frequency is above 1000Hz, the frequency does not change with speed, but with the acceleration of speed of sound pressure level added. Roller bearings, its acoustic sound pressure level as the viscosity of the Raceway adds cut; sound small car Raceway bearings, the sound pressure level of viscosity by adding up to about 20mm2/s above, reduced to nothing by deleting it. Greater the rigid housings, acoustic sound pressure level of the lower of the Raceway. Went on the radial clearance is too small, acoustic sound pressure level of the Raceway and will fight from the frequency went on the radial clearance reduction and sharp added. Raceway sound manner without moderation: Optional low noise bearings bearing corrugated-small, carefully selected prerequisites. Sound effects often zero mechanical noise of the Raceway, cutting Raceway could cut to zero the mechanical noise.
Moving sound and how it is measured the impact of the larger models of ball bearings or bearings being under purely radial load when running at low speed, smaller due to the centrifugal force of the moving body, is not loading area will impact the move of links or raceways and making noises. But with anti-speed forward, that kind of sound will be inclined. Abstinence means no impact on the move: proper radial cuts go to gap, without rational distribution of material, and no links to the mild bracket bearing.
INA bearings the creak and moderation creak bearing is no place is the possibility of harsh metal sound unpleasant, mostly larger models of grease lubrication bearings which are more difficult outside the base oil functional deterioration of grease, oil hardly occurs when.
In addition, winter is more difficult, when the bearings are subjected to purely radial load, being light went on the radial clearance larger places difficult, and with model size differences is speed of light within the context of a particular difficulty, both continuing and intermittent flush. External ring road to adopt special processing methods to creak-proof flush, if required, the choice of bearings, or proper bearing radial cuts go to gap, use function goes bad before the show grease and enterprising bearing parts of rigid.
