TIMKEN roller bearing what diagnosis of injury countermeasures

For make scroll bearing has of performance, in good of conditions Xia to maintained long-term using, must on rolling bearing for check and maintenance, this check and maintenance, on ahead of prevention fault is is important of, hope according to for machine running conditions of operation standard, for regularly check and maintenance, General used following method: running state Xia of check according to TIMKEN bearings of scroll sound, and vibration, and temperature of check and lubricant of nature check, lubricant of added or replaced time for judgment.
Simple diagnosis of rolling bearing
1, the monitoring of rolling bearing using auscultation method
Working state monitoring of rolling bearing using auscultation method commonly used tool is a long wooden handle screwdrivers, you can also use the hard plastic of the outer diameter is around 20mm. In contrast, using electronic stethoscopes for monitoring, improves the reliability of the monitoring.
2, monitoring by magnetic method for rolling bearing
Magnetic plug only suitable for lubricant, and through a dedicated pipeline back to monitor the critical main bearing oil.
Magnetic mount monitor near the main bearing, is back on the main channel of the oil, there are no filters, hydraulic pumps and other hydraulic barrier.
3 monitoring, bearing measurement method for rolling bearing
By measuring the operation temperature of TIMKEN bearings, it is difficult to monitor bearing fatigue spalling, arising from localized damage such as cracks or indentation, especially in the early stages of injury almost impossible to discover any problems. When the bearings after long-term functioning, when there is a temperature rise, as reflected by the general issue as it had been serious, and the rapid development of bearing damage caused failures. At this time, intermittent monitoring will often cause leakage supervision. Monitoring found in bearing temperature exceeds 70-80 ° c, should be immediately shut down to check.
Check full observation of periodic inspection and replacement of the machine for rolling bearings TIMKEN bearings removed, check the condition of Raceway surface and no damage and the possibility to use again. Under proper use, the bearings, can have very long life. if injury occurs prematurely, is most likely the selection error, caused by improper use or poor lubrication.
Therefore, when installing the TIMKEN bearings, we need to record the machine type mount, use conditions and tie around. Research Summary by type of rolling bearing damage, use environment when a problem occurs in order to prevent the recurrence of similar situations.
