Effect of force application assembly and disassembly INA joint bearing on the life of the

The main task of the service life of joint bearing, is based on the analysis of data and the failure form of the large amount of background material,, find out the main factors causing bearing failure, so as to put forward the improvement measures, extending the service period of INA bearings, avoid unexpected early bearing failure.
Factors that affect the service life of the joint bearing may have a lot of, can from the use of factors and internal factors to further instructions.
Using the factor mainly refers to the installation and adjustment, maintenance, maintenance and repair compliance with technical requirements. According to the requirement of the joint bearing installation, use, maintenance, maintenance technology, INA bearings in the running to take the load, speed, temperature, vibration, noise and lubrication condition monitoring and inspection, found abnormal immediately find reasons, adjust, make its restore normal. Installation conditions is one of the leading factors in the use factor, joint bearings are often caused by the installation of inappropriate stress state between the parts of the whole set of bearing change, bearing an abnormal state operation and early ending life.
As long as the assembly and disassembly of INA bearing when the size of the force should be smooth and uniform, matters needing attention, cannot have the impact force to continue to work, it will not appear when installing the bearing damage.
The metallurgical quality of bearing materials used are the main factors influencing the early failure of joint bearing. With the development of Metallurgical Technology ( such as vacuum degassing of steel bearing ) progress, improved quality of raw materials. Raw materials quality factors has been a marked decline in the proportion of bearing failure analysis, but it is still one of the main influence factors of INA bearing failure. Proper selection is still bearing failure analysis must be considered.
Manufacturing joint bearing generally after forging, heat treatment, machining, grinding and assembling multi-channel processes. Rationality, advanced processing technology, the stability will also affect the service life of bearing. The effect of heat treatment quality of INA bearings and machining processes, often has a more direct relationship with the bearing failure.  

Previous: INA bearing need to be aware of several installation and replacement method
Next: Before the repair of KOYO bearings do measurements.
