Bearing judgment is available to consider the degree of bearing damage, mechanical properties, the importance of operating conditions, to decide during the next overhaul. If you have the following defects can no longer use, must be replaced with new bearings. The inner ring, an outer ring, rolling elements, on any one of the holder there are cracks or notches.
First, reasonable structure design also has advanced, and will have a longer bearing life. Bearing manufacturing ordinary multi-channel processing through forging, heat disposal, turning, grinding and assembly. Reasonable process, advanced, invariance can also affect the life of the bearing. Affect the quality of the products bearing the thermal disposal and grinding processes, tend to have a more direct relationship with the bearing out efficiency. Seminar marked layer of the bearing task appearance metamorphosis in recent years, the close relationship of the grinding process and the bearing outer quality.
Bearing metallurgical quality of the information used to affect the primary elements of the rolling bearing early out efficiency. Followed the metallurgical skills (such as vacuum degassing bearing steel, etc.) to improve the original data quality improvement. The proportion of the original quality of the data elements in the bearing off efficiency profiling have clearly declined, but it still is bearing out the efficiency of the primary elements. The selection whether proper still bearing out efficiency profiling necessary to think about the elements.
Bearing out efficiency parsed primary obligation is based on a lot of sets of data, analyze data and swap effective way to identify the formation of the efficiency of the primary elements of the bearing out, so that the proposed modified approach, extending bearing executive service constitutes prevent bearing seizures the unexpected early swaps efficiency.
Check status near the bearing at the oil seal to ensure that they are sufficient to prevent hot liquids, corrosive liquids and gas infiltration along the axis of the bearing oil seal if damaged should be replaced as soon as possible. Check the automatic lubrication system to ensure that the oil or grease into the bearing, and ensure that the correct amount of add check lubricant is discolored or black, if this situation usually indicates a lubricant containing impurities, this case bearing is harmful.
Bearing failure and deterioration of performance status parameters to determine and predict the reliability and performance of the bearing, the site of the abnormal situation, because the degree of risk identification and judgment, decided to repair and improve the methods of comprehensive technology. Therefore, bearing fault diagnosis technology is not simply the fault detection (or monitoring) technology, is not a pure point inspection instrumentation. Right, quickly, effectively signal acquisition, data processing, manual or automatic identification and judgment. In order to determine the repair cycle of science, should be based on the types of failure mechanisms of fatigue, wear life necessary tests and estimates.
