Agency operation, TIMKEN bearings installation parts to allow a certain degree of temperature when touching body shell with your hands, not feeling infected hot should be the normal, on the other hand it means that bearings temperature through high.
Bearing temperature through high duanyou: lubricating oil quality differences or metamorphic, lube oil viscosity through high body assembled too tight (open-idle is not sufficient); TIMKEN bearing Assembly too tight; scroll housing washer on the shaft or housing; load too large; bearing maintenance or fragmentation.
Bearings in the functioning of the Office are permitted in tiny sound, if the sound is too loud or unusual noise or a crash, it indicates that the TIMKEN bearing is faulty.
1, axle bearing for the maintenance, checking, and exception handling
In good condition as long as possible to maintain TIMKEN bearing function, maintenance, inspection, with a view to preventing accidents early intervention program, ensuring reliability of operation, produced, economic progress. Maintains the best machinery functioning scale provided lessons, on schedule. Contents include, supervision and operation, addition or replacement of lubricants, arranging the demolition of inspection.
As a matter of running test, a lubricant for bearings of rotating tones, vibration, temperature, status, and so on.
2, bearing failures and solutions
In General, if accurate TIMKEN bearing, you can use up to meet the required fatigue life. But there are accident prematurely damage, not in use. This early injury, and fatigue life, on the quality limits are known as faults or accidents. Result from the installation, use, lubricate on the don't look out, from external intrusion by foreign bodies, shafts, case study on thermal effect of inadequate.
