Processing IKO bearing burn maintenance pay attention to the point

IKO bearing inspection in operation is very important, cannot be ignored, check the main bearings of rolling noise, vibration, temperature, smooth state, and so on. We will start with simple introduce you the bearings of rolling, the size of the rumbling and quality check sound device should be used to stop inspection of auto bearing in operation, with advanced tools can accurately identify the problem, bearing even with slight stripping damage, also an exception and irregular, and with the sound of the measuring device can distinguish. Then IKO bearing vibration test to check the bearing damage is very sensitive and can peel, indentation, rust, crack and wear will be reflected in the bearing vibration measurement, so, through the use of special automobile bearing vibration zhangs gauge ( Frequency profiler, etc. ) Can measure the size of the vibration, through frequency points cannot deduce the abnormal condition in detail. But each machine measured values for bearing or sensor installation position and different using conditions, and thus needs prior to measurement value of each machine stop after certain discriminant analysis compare specifications. IKO bearing parts in use by the influence of abnormal high temperature, cooling, without timely and will generate a high temperature tempering parts appearance organization or secondary hardening phenomenon called burns. Burns, the main reason is adverse, neck load is too large, smooth clearance improper selection, bearing misallocation, raceway looks poor contact, such as stress caused by a cold. Such as; 1) In swimming axial bearing, if the external fit too tight, cannot move in casing hole; 2) The bearings work in the operating temperature, shaft heat shrinkable provoked large axial force, and bearing axial move and can't; 3) Due to smooth, smooth or agent selection is not reasonable, quality problems, aging and transformation, etc. ; 4) Operation of internal cause and external cause temperature difference is big, improper selection and clearance large external cause charge to reduce the internal cause is interference from bearing temperature rise sharply; 5) IKO bearing accept load is too large and cutting load distribute uneven, a stress concentration; 6) Rough machining parts appearance, form poor contact or oil film composition. Burn appearance characteristics can according to the appearance of color to distinguish. IKO bearings in use due to reasons such as smooth agent, temperature, corrosion, parts appearance will attack changes, mainly with light yellow color, yellow, palm red, purple, blue and dark blue, light yellow, yellow, palm red chips in color ( See the related content) , if appear purple blue or bluish black action for burns. Burns easily formed parts appearance landing or render tiny grain hardness.
