The latest theory of motor bearing fatigue life

Generally speaking, the service life of motor bearing is refers to the rolling bearing in the actual service conditions ( Including working conditions, environmental conditions and maintenance and maintenance, etc. ) Satisfy the requirement of active, can continue to keep working performance and precision of the specialty service period. The significance of this theory is that it not only provides a live equation is more reliable than Imos forecasting tools of modern bearing life, and is that it shows all the fatigue life of rolling bearing has a considerable development potential, and shows the ways to develop the potential, thus to bearing product development, quality management and application of technology has a profound impact. Bearing, however, is only possible in the laboratory under the condition of infinite 'implementation', and this kind of condition for bearing under certain condition of field use, both difficult to is too expensive. Field use bearing, the work load is often greater than its corresponding fatigue durability limit load, after the work to a certain time limit, or late or early due to the material itself will always reach contact fatigue limit and fatigue spalling and cannot continue to use. Even if some bearing working load is lower than its corresponding durability limit load, also due to the bearing the problem of pollution of hard to eradicate the wear failure occurred. To sum up, the scene of bearing more or less in use can't fully meet those of the lab conditions, and slightly in either condition, will reduce bearing period are available, and this leads to the life of the bearing problem. According to the latest motor bearing fatigue life theory, an excellent design, excellent material, excellent manufacture and install the correct bearing. As long as enough to easily subjected to the load ( No greater than the corresponding a durability limit load bearing value) , the bearing will never produce fatigue damage of materials. The bearing will run indefinitely. 1, through the voice recognition through the voice recognition need to have a lot of experience. Must go through adequate training to achieve voice can identify the bearing and the bearing. Therefore, should as far as possible from staff to carry out the work. With listening gear or listening bar on the shell can be clearly heard the sound of the bearing. 2, through the work temperature identification belong to compare recognition method, this method is limited to use in place of running condition is not change. Therefore, must carry out continuous recording of temperature. Failure, the temperature rises not only, still will be irregular change. The method and voice recognition method and advisable. 3, through the state of lubricant, and the recognition of lubricant sampling analysis, through its pollution degree, whether into foreign body or metal powder, etc. The method for larger cannot close observation of bearing or bearing are particularly effective.
