In the FAG premature bearing damage cases, about 25% is due to improper installation or use of the correct caused. Various applications may need to install the method to correctly and efficiently install car hub bearing for heating, mechanical or hydraulic. Select the installation method is suitable for applications that will help extend bearing service life, and reduce the cost caused by premature bearing failure and potential damage to the applications and the.
1, the bearing installation method: heat the oil bath heating bearings, this method may hub bearing the automobile pollution, lead to premature bearing damage. Induction heating is the most commonly used means of heating of FAG bearings, it is because their control, efficiency and safety are high. Some bearing manufacturers determine the induction heater for bearing applications research and development standards. Automobile hub bearing induction heater has many functions, help prevent damage to bearings in the heating process.
2, bearing cold installation:
General small and medium-sized bearing uses cold installation. Traditionally, the bearing is installed with a hammer and a section of the old pipe. This approach can lead to external components to pass through the rolling, which damage the raceway. Bearing installation tool will force imposed on the press fit bearing rings, helps prevent bearing damage.
Installation of hydraulic technology, bearing 3:
FAG bearings are the pioneers the use of hydraulic technology in the installation, these techniques include oiling method and drive tight installation method. These methods can help simplify the bearing configuration, help to correct and easy to install bearings. Automobile hub bearing the company has also developed a number of tools and equipment for bearing installation of hydraulic technology, the hydraulic technology implementation.
The cause of premature failure of automotive wheel hub bearing is in many aspects, but the main use and improper maintenance and improper lubrication, lubrication, pollution, assembly, disassembly, transportation overload occurs during impact and shock. Are man-made pollution, because disassembly tool did not wash clean etc..
The influence of clearance, clearance between the shaft and the shaft is too large, the relative movement between a shaft section, with excessive wear gap is more and more big, finally cause the automobile hub bearing scrap : two is bearing crack, affecting the precision of motion. The cause of premature bearing failure, is detrimental to our practical work, therefore, research on how to avoid premature failure of FAG bearing, prolong the service life is very practical value.
The most effective way to prevent premature bearing failure are various factors as far as possible to avoid the above analysis and contributed to these factors : first of all, should choose FAG bearings before use, taking into account the noise size, the size of the bearing rigidity, radial crack size, the torque size etc.. Selection of lubricating oil, according to automotive wheel hub bearing working environment, the lubricating medium different have different noise in use.
