IKO bearing fault and damage on the effect of using analytical

1. Metal flake bearing raceway appearance and inner and outer ring raceway surface are accepted the role of the periodic pulse load, resulting in a periodic change of contact stress. When the stress cycles to reach a certain value, after work in the body or the inner and outer ring raceway surface will produce fatigue spalling. If IKO bearing load is too big, can make this kind of tired. In addition, the bearing assembly is not straight, shaft bending, also can produce roll flaking off. Bearing raceway fatigue spalling can reduce the running accuracy of shaft vibration and noise agencies attacks. 2. Bearing burn burn IKO bearing raceway, the body has the heat tint. Burns the cause of the lack of common is smooth, smooth oil quality will not fit the request or metamorphosis, and bearing assembly too tight. 3. Plastic deformation of bearing raceway and roller contact surface appear uneven pits, clarify bearing produce plastic deformation. Its reason is bearing in large under static load or shock loading, beyond the appearance of part stress data of yield limit, this situation general attack on low speed spinning IKO bearings. 4. Bearing race crack crack reasons at the bearing race may be bearing fit tight, loose foreign or bearing inner ring, hold a distortion of bearing, gear bearing appearance processing etc. 5. Stick to fracture at the reason is the lack of smooth, broken body, seat tilt, etc. 6. Adhere to the metal adhesive on the body of possible reason is that body was stuck on frame or lack of smooth. Seven ring raceway serious wear any IKO bearing the use of life depends, in great level of maintenance and enjoy it. This especially in industrial applications, are often poor working conditions, and heavy load, dust and pollution is a common range. First of all, reasonable structure design and equipped with advanced, just can have a long bearing life. Bearing manufacturing to ordinary after forging, heat treatment, turning processing, grinding and assembly process. The rationality of the processing technology, advanced, stability will also affect the IKO bearing's life. Which affects the quality of scrap bearing heat treatment and grinding process, often have a more direct relationship with bearing failure. In recent years the discussion of the bearing work appearance transformation layer indicate that close ties to the quality of the grinding process and its appearance. Then, the main reason of bearing failure analysis is on the basis of a large amount of background information, analyze the data and the failure mode, find out the bearing failure of main elements, so that a targeted improvement measures are put forward, a longer IKO bearing retirement period, to prevent a sudden attack of early failure. Finally, bearing materials metallurgy quality were the main factors affecting the premature failure of the rolling bearing. As metallurgy technology, For example, the bearing steel vacuum degassing, etc. ) The progress of the original data quality improvement. Original data quality elements in bearing failure analyze the proportion of land had obvious, but it is still the major effect of the bearing failure, can select material IKO bearing failure analysis of thinking elements.
