Bearing failure for many reasons, all the factors affecting the design and manufacturing process will be related to the failure of the bearing, the analysis is not easy to judge. In general, in general, from the use of factors and internal factors in both the consideration and analysis.
The use of factors mainly refers to the installation adjustment, maintenance, repair, etc. meet the technical requirements. Installation conditions is one of the primary factors in the use of factors, the bearings are often due to improper installation and lead to the entire bearing between the parts of the force state changes, the bearing in abnormal state of operation and early failure. According to the bearing installation, use, maintenance, maintenance of the technical requirements of the bearings in operation under load, speed, operating temperature, vibration, noise and lubrication conditions for monitoring and inspection, find the cause of the anomaly immediately to adjust to Back to normal. In addition, the quality of grease and the surrounding medium, the atmosphere is also important to analyze the test.
Internal factors mainly refers to the structural design, manufacturing processes and material quality determine the bearing quality of the three factors.
First, the structural design of a reasonable at the same time have advanced nature, will have a longer bearing life. Bearing manufacturing generally go through forging, heat treatment, turning, grinding and assembly processes such as multi-channel processing. The processing of the rationality, advanced, stability will also affect the bearing life. Which affect the quality of finished bearing heat treatment and grinding process, often with the bearing failure has a more direct relationship. In recent years, the work of bearing surface metamorphic layer of research shows that the grinding process and the bearing surface quality are closely related.
Metallurgical quality of the bearing material used to be a major factor in the early failure of rolling bearings. With the metallurgical technology (such as vacuum degassing bearing steel, etc.), the improvement of raw material quality. The quality of raw materials in the bearing failure analysis of the proportion of factors has been significantly reduced, but it is still one of the main factors of bearing failure. Selection is still bearing properly whether the failure analysis must be considered.
Bearing failure analysis of the main task is based on a large number of background materials, analysis of data and failure forms, to identify the main factors causing bearing failure in order to put forward targeted improvements to extend the service life of the bearing to avoid bearing sudden Of the early failure.
