Affect the SKF bearing service life - bearing the cause of knowledge

The influencing factors of SKF bearing service life may have many, use factors and internal factors, could further instructions. Use factors mainly refers to install, use, maintenance, maintenance, repair and so on meets the technical requirements. According to SKF 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. Installation condition is one of the primary factor of use factor, bearing is often caused by improper installation of a complete set of change the stress of bearing between various parts, bearing in the abnormal state of operation and the service life of the early end internal factors mainly refers to the structure design, manufacturing process and material quality and so on three major factors in determining the quality of bearing. Imported bearing materials metallurgy quality was the main factor affecting 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 the 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. 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 products 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. SKF bearing service life analysis of the main tasks, it 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, prolonging bearing, avoid premature failure of the bearing of the sudden.
