KOYO bearing operational failure cause analysis

KOYO bearing failure is often the result of many factors, all of the design and manufacture of the influence of technological factors and bearing faults, their analysis is not easy to determine. Under normal circumstances, in general, you can consider and analyze the factors and internal factors. Used to adjust the main factor is the installation, use and maintenance, maintenance, such as conform to technical requirements. Installation conditions is one of the factors of using KOYO bearings is often caused by incorrect installation package state changes between each part of the primary factor of bearing capacity, the abnormal state of operation and early failure. According to the bearing installation, use, maintenance, maintenance of the technical requirements of operation of the bearing contact load, speed, temperature, vibration, noise and lubrication condition monitoring and inspection, found that abnormal immediately to find the reason, adjust back to normal. In addition, the quality of oil and the surrounding medium, the analysis of the atmosphere is also very important tests. Bearing the chamfer does not determine the quality of the bearing, but it reflects the bearing processing method. Chamfering is black, the heat treatment such as quenching hardness of this bearing, and some people think the chamfering is black not good-looking is not process completely, this is a myth. A cage is better than two body, although the new process using one cage, but it is just to save material, and performance than the difference between the two bodies such as the rotary. KOYO bearing chamfer does not determine the quality of the bearing, and some people think the chamfering is black not good-looking is not process completely, this is a myth. Internal factors mainly refers to the structure design, the quality of the workmanship and materials, there are three factors determine the quality of the bearing. First, the structure design and advanced at the same time, there will be a longer KOYO bearing life. Bearing manufacturing through forging, heat treatment, cutting, grinding and assembly process operation. The rationality of the processing, advanced, stability will also affect the service life of bearing. Affect the bearing heat treatment and grinding process, often associated with bearing fault more direct relationship with the quality of the product. In recent years, the deterioration of the surface layer of the bearing show that the grinding process is closely related to the bearing surface quality. Is the main factor influencing the quality of bearing material metallurgy rolling bearing early failure. With the progress of metallurgical technology ( Such as bearing steel, vacuum degassing, etc. ) , improve the quality of the raw materials. The proportion of raw materials quality factors in the analysis of the bearing is markedly reduced, but it is still one of the main factors of KOYO bearing failure. Choose proper is still bearing failure analysis must be considered.
