Bearing fault factors account for a large proportion design and manufacturing process

Bearing fault design and manufacturing process factors account for a large proportion, and the bearing fault, their analysis is not easy to determine. Under normal circumstances, in general, you can consider and analysis and internal factors. Main factors adjust the installation, operation and maintenance, maintenance, etc. Is one of the factors of using bearing installation conditions, is usually caused by packaging components not correct load changes, abnormal state of operation and the main factors of early failure. According to the bearing installation, use, maintenance, maintenance technology, the bearing contact load, speed, temperature, vibration, noise and lubrication condition monitoring and inspection, found that abnormal immediately found the reason, adjust the normal. In addition, the quality of the grease and the surrounding medium, the atmosphere also analysis and test is very important. Bearing chamfer not sure the quality of the bearing, but it reflects the bearing processing method. Chamfering is black, said bearing hardness and other heat treatment after quenching. Some people think that the chamfer is black, not good-looking. It is not completely. This is a misunderstanding. Integral cage is better than two body, while the new process USES the whole cage, it is just to save material, and spinning performance is worse than the body. Bearing chamfer not sure the quality of the bearing, and some people think the chamfering is black, not good-looking, not completely, this is a misunderstanding. Internal factors mainly refers to the structure design, manufacturing process and material quality, three factors determine the quality of the bearing. The first first, the use of advanced structural design, there will be a longer bearing life. Bearing manufacturing will through forging, heat treatment, cutting, grinding and assembly process is finished. The rationality of the processing, advanced and stability will also affect the service life of bearing. The influence of heat treatment and grinding process on the bearing is often related to the quality of the bearing failure and related products. In recent years, the research shows that the degradation of the surface layer of bearing grinding is closely related to the surface quality of the bearing. The role of the metallurgical quality of bearing material is the main factor in the premature failure of the rolling bearing. As metallurgy technology, Bearing steel, vacuum degassing, etc. ) Progress, to improve the quality of raw materials. Raw material quality factor in the bearing failure analysis the proportion of obvious drop, but still is one of the main factors of bearing failure. Is the right choice is still a bearing failure analysis must be considered. Bearings after installation, in order to check whether installed correctly, check for running. The small machine can rotate to ensure smooth by hand. Check scars caused by foreign bodies in the engineering, the indentation is not normal, because of the bad installation, the installation process of torque is not stable, because of the gap is too small, large installation error, causes such as seal friction torque is too large. If there is no exception, the beginning of power operation. Remove the bearing, the first record the appearance of the bearing, to confirm the amount of remaining oil, and then check to clean the bearing lubricant. Common use gasoline, kerosene as a cleaning agent. The dismantling of bearing cleaning rough washing and fine washing, respectively. In the container, metal mesh placed at the bottom, so the bearing will not have direct contact with the dirt from the container. When cleaning, if there is dirt rotating bearing, can damage the bearing rolling surface, should be paid attention to. In the coarse clean oil, use a brush to remove grease, adhesives, clean, and then into the fine cleaning. Fine cleaning is to bearing when they carefully cleaned in cleaning oil. In addition, the clean oil is always kept clean. In order to judge whether the bearing of the removed can be used to check the bearing cleaning, carefully check the rolling, rolling surface, cooperate with the state, increase shelf wear and bearing clearance and imprecise drops size and abnormal damage. To handle the support the separation type ball bearing inner ring spinning outer confirm whether well or not. From the shape of the bearing, you can check in the outer ring raceway surface, rolling body, large bearing can turn, check the rolling element and raceway surface, cage, the application of metope bearing, comfortable and durable, )
