Timken bearings rotate when the bearing inner ring and outer ring raceway surface due to contact with the rolling scrolling, and running track to the dark side, running track attached to the Raceway surface does not belong to an exception, this variable may be able to tell the load conditions, so when the demolition of tapered roller bearings, please pay strict attention and observation of Raceway surface running track.
1. Reconciliation of actual load and speed of the Timken bearing 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 tapered roller bearing of adjacent machine components during this time 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 characteristics configuration characteristics of Timken bearings and tie in the host, determine whether the configuration is appropriate, write down the ring relative to the location of the shell and position relative to the direction of load;
4. Shaft with her hands together with corrupted try going a few ring of tapered roller bearing 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 Timken bearing is located parts, identified lubrication; situation and pollution situation, audit lubricant grades and sealed way whether wrong, attention in has temperature rose situation Shi, tapered roll child bearing temperature whether over by with lubricant of temperature limited, focus check oil bit high and low, sealed gap whether leak oil leak fat, and water, and dust grain or other foreign body whether has intrusion bearing, for oil system has whether fault
6. To see whether there has an impact on Timken bearings of vibration sources. Debris or fluid or particle source, water pollution, flows through the current source of tapered roller bearings;
7. Depending on circumstances, could serve as a basis to judge the tapered roller bearing damage due to fretting corrosion, wear and tear, rust or corrosion is.
If you look closely at the track, you will learn that only burdens radial loads, bear large axial loads, moments of endurance load, or extreme rigidity on bearing boxes are not equal. Can check the tapered roller bearings are combined with an unexpected load and install error is too large, and became a holding loss for clues to the cause of Timken bearings.
