Bearing failure analysis

Rolling bearing as machinery and equipment parts are widely used in major industrial sectors. In spite of the preventive maintenance, especially the application of the advanced predictive maintenance technology, for the vast majority of machine fault, we were able to discover, in the early stages of the failure and take corrective action as early as possible. Usually rarely appear the phenomenon of early failure of bearing. But we also often find it on the same equipment, the same machine fault is always appear repeatedly. This means that we don't have any for debugging measures taken root, the fault as a result, the failure root cause analysis is very necessary. Bearing failure may be caused by many reasons, only check the bearing itself is difficult to really find out causes of failure of bearing, bearing of usage and their running environment, lubrication condition and related parts has a great relationship, it is only through a series of information collection and analysis, the relevant analysis method and auxiliary equipment, to find out the real causes of bearing failure. We are limited to the analysis of the causes of the failure of your analysis, the damage of machine parts provided by our strengths is that through the information provided by the extensive and in-depth analysis, find the root cause of equipment failure, and put forward reasonable Suggestions to improve the maintenance, even also can help the original equipment manufacturer of machines or key components design. 1 rolling bearing failure cause bearing failure analysis method. Get the run data from bearing monitoring device. 2. Prepare a check form to record all watch. 3. Extraction used lubricant samples, packing and label separately. 4. Extract the unused lubricant samples, information data or batch record specifications. 5. Check the bearing in the environment of the application of some external factors. 6. Remove the equipment. 7. Check the status of the rest parts. 8. Before disassembly, mark the installation position of the bearing and other parts. 9. Measuring the size of the bearing and the bearing seat, roundness and taper. 10. Before completion of disassembly, cleaning parts, record the observation results of the distribution and state of lubricant. 11. Clean the parts, and write down the parts information. 12. Analysis of the internal surface of the rolling contact, load area and the corresponding external surface condition. 13. Coated with anti-rust oil and repackage good bearing, in order to avoid corrosion. In an article: the type of bearing life next up: the basic knowledge of bearing installation, learn it again
