IKO common affliction of cylindrical roller bearing damage solution principle

1) IKO bearing during operation if a rhythmic beat or voice, may be due to the cylindrical roller bearing raceway spalling, indentation, or other parts improper installation; 2) Found a 'goo IKO bearing the importance, goo importance' voice, may be due to the bearing seal is lax, lubricating oil is not clean, due to the bearing clearance is too large; 3) Found 'cheep nowadays, cheep bearing nowadays' screaming voice, may be caused by lubricant dry or lack of lubricant. 4) If found the sound of 'n oise' bearing, may be a cylindrical roller bearing was not clean, internal mixed with abrasive dust, sand, dust and other sundry; 5) Bearing inner ring overheating, bearings and seals and related parts friction; 6) Installing a IKO bearings, by banging on bearings or other parts, cause deformation of bearing; 7) Bearing on the set set of too tight or loose; 8) The size of the bearing housing is too big ( Including the use of larger) And so on, are likely to make the bearing noise and abnormal sound. Cause of roller bearing vibration, basically the same as the causes of bearing noise and abnormal sound, there is a strong correlation between both. But is beyond the scope of the audio frequency, will not cause abnormal noise and sound. Rolling mill bearing of rolling mill and its control method is cylindrical roller bearing in the harsh metal can occur in all occasions, mostly happens in large type bearing grease lubrication, and in the base oil performance degradation occurred more often in the grease, almost does not occur when oil lubrication. In addition, more easily occur during the winter, when under pure radial load, the radial clearance prone to big occasions, and with different size, easy to happen in a certain speed range, both continuous and intermittent. External ring raceway take special processing method can prevent the occurrence of roll ring, can choose this kind of high temperature bearing, if necessary or appropriate to reduce bearing radial clearance, the use of high performance grease and improve the rigidity and cylindrical roller bearings are suitable parts. ( 1) Choose low noise bearings; It depends on the cylindrical roller bearing, buy high quality generally good IKO bearings are made of high material steel, with high density, the characteristics of high patience; ( 2) Try to eliminate noise from the bearing application link, is in the link above to add lubricating oil, must choose good lubrication materials, can be twice the result with half the effort. ( 3) Sensitive to avoid resonance with the host, to avoid the resonance speed; This need professional installation and debugging, can avoid resonance problem; ( 4) If the other method is invalid, sound insulation and noise elimination of additional measures, install some voice control equipment, etc.
