Find steps bearings FAG bearings damage cause the operation as a result of irregularities should be timely identification of causes and troubleshooting. FAG bearings in use after a certain period, total failure or damage, such as analysis of damage and to take corresponding countermeasures, can improve its service life and operational reliability, reduce the number of host maintenance and costs, extend the life master. Bearing the following common characteristics of damage, damage to discovery and analysis of the causes of, and effective measures to prevent or mitigate the damage.
In front of the demolition of the damaged FAG bearings-step review of the calculation of the bearing load and calculation speed, and so the original data, note that the original design whether there had been any omissions or errors
1. Verify the actual load and speed of FAG bearings differed from the original not gauge whether, bearing selection is correct;
2. Aware of damage, as well as close to the corruption of anomalies, in particular the State and evolution of the emergence of situations such as noise and heat; attention to check the power supply and FAG bearings adjacent machine components in the meantime there is no anomaly. Analysis of noise type, high and low tone, rhythm of frequency interference: notice when the temperature suddenly increases, and so on, note the power supplies and the situation in other parts;
3. Identify hosts in the configuration and combined with characteristics of FAG bearings, whether or not configured properly, note the rings relative to the shell and position relative to the direction of load;
4. FAG bearings shaft with her hands together with corrupt try go few laps to experience running heavy levels, promoting several times back and forth along an axis to an axis to experience axis along the axial tension and, if necessary, measure the deflection of the shaft;
5. Check the FAG bearing parts, identifying lubrication and pollution, whether audit grade lubricant and seal in error, note when temperature rise, bearing temperature exceeds the temperature limits of the lubricants, focus check oil level level seal leak oil leak fat, as well as water, dust or other foreign bodies are penetrated bearings, oil supply system has any faults
6. See whether there has an impact on FAG bearing vibration sources. Debris or fluid or particle source, water pollution, flows through the bearing of current sources;
7. Depending on circumstances, could serve as a basis for judgment of FAG bearings damage is due to fretting corrosion, wear and tear, rust or corrosion is.
