The main reason causing the failure of the SKF thrust ball bearing

SKF thrust ball bearing failure for many reasons, all the influence factors of design and manufacturing process will be associated with the failure of thrust ball bearing, the analysis 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, thrust ball bearings are often caused by improper installation of a complete set of thrust ball bearing stress changes between various parts, thrust ball bearing in the abnormal state run and early failure. According to the thrust ball bearing installation, use, maintenance, maintenance of technical requirements, the operation of the thrust ball 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 thrust ball bearing. First of all, reasonable structure design and equipped with advanced, will have a longer thrust ball bearing life. Thrust ball 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 thrust ball bearing's life. Which affects the quality of the finished thrust ball bearing heat treatment and grinding process, often with thrust ball bearing failure has a more direct relationship. Metamorphic layer on the surface of a thrust ball bearings work in recent years, the study shows that the grinding process and is close to the surface quality of thrust ball bearing. SKF thrust ball bearing materials of metallurgical quality were the main factors influencing the premature failure of the rolling thrust ball bearing. As metallurgy technology, For example, the thrust ball bearing steel vacuum degassing, etc. ) Progress, raw material quality is improved. Raw material quality factor in the proportion of thrust ball bearing failure analysis of the has declined obviously, but it is still one of the main influence factors of thrust ball bearing failure. Select material whether correctly is still a thrust ball bearing failure analysis factors must be considered. SKF, the main task of the thrust ball bearing failure analysis is based on a lot of background material, analyze data and failure forms, find out the main factors of thrust ball bearing failure, so that the improvement measures are put forward, extension of thrust ball bearing, avoid sudden thrust ball bearing early failure.
