Three major factors affecting FAG plastic bearing failure

Plastic bearing failure for many reasons, all the influence factors of design and manufacturing process will be associated with the failure of FAG bearing, analysis it is not easy to judge. In general, generally can be used from the two aspects of factors and internal factors considered and analyzed. Use factors mainly refers to install, use, maintenance, maintenance, repair and so on meets the technical requirements. Installation conditions is one of the primary factor of use factor, FAG bearings are often caused by improper installation of a complete set of change the stress of bearing between various parts, bearing in the abnormal state run and early failure. According to the bearing installation, use, maintenance, maintenance of technical requirements, the operation of the bearing on the load, speed, temperature, vibration, noise and lubrication condition monitoring and inspection, found that abnormal immediately to find the reason, adjustment, so that it is back to normal. In addition, analyze the grease and the surrounding medium, the atmosphere quality inspection is also very important. Internal factors mainly refers to the structure design, manufacturing process and material quality and so on three major factors in determining the quality of FAG bearings. First of all, reasonable structure design and equipped with advanced, just can have a long bearing life. Bearing manufacturing generally go through forging, heat treatment, cutting, grinding and assembly, and multi-channel processing operations. The rationality of the processing technology, advanced, stability will also affect the service life of bearing. Which affects the quality of finished product FAG bearing heat treatment and grinding process, tend to have a more direct relationship with bearing failure. In recent years the study of metamorphic layer of bearings working surface show that the grinding process and is close to the surface quality of the bearing. Plastic bearing materials metallurgy quality were the main factors influencing the premature failure of the rolling bearing. As metallurgy technology, For example, the bearing steel vacuum degassing, etc. ) Progress, raw material quality is improved. Raw material quality factor in FAG bearing failure analysis share has declined obviously, but it is still one of the main influence factors of bearing failure. Select material adequacy is still bearing failure analysis factors must be considered. , the main task of the plastic bearing failure analysis is based on a lot of background material, analysis data and failure forms, find out the main factors of bearing failure, so that the improvement measures are put forward, extend FAG bearing, avoid premature failure of the bearing of the sudden.
