Cylindrical roller bearing failure occurred during operation is often the case, so you don't have to make a fuss. There is fault, judgment and treatment is the key.
1. bearing temperature too high
When the institutions, mounting SKF bearings parts allows a certain degree of temperature, when you touch body shell with your hand, should not feel hot to normal, instead it indicates that the bearing temperature is too high.
High temperature cylindrical roller bearings of reasons: quality does not meet the requirements or deterioration of lubricant, lubricant viscosity is too high; body fitted too tight (insufficient gap), SKF bearing Assembly too tight; bearing washer on the shaft or in the shell rotation; load too large; bearing cage effects of fragmentation, such as or.
2. bearing noise
Minor operation is allowed in the work of rolling bearing noise, if the sound is too loud or abnormal noise or impact sound, then bearing is faulty.
Causes noise rolling bearings are more complex, one is the inner and outer rings mating surfaces of the bearing wear. Due to the wear, undermined and shell of cylindrical roller bearings, SKF bearing and shaft meet relationship, causes the axis deviates from the correct location, noise resulting from the axis in high-speed motion. When you are bearing fatigue, its surface metal flake, also bearing radial clearance increases the noise. In addition, insufficient lubrication of the bearing, the formation of dry friction and bearings broken produces abnormal noises. After bearing wear loose, loose cage damage, would also have abnormal noise of bearing failures.
1, heavy cleaning, use brushes to remove grease, stickers, generally after a clean, sperm washing. If you rotate the SKF bearings with dirt, can damage the bearings of rolling surface, should be noted.
2, fine finishing wash, are cylindrical roller bearings cleaning rotating in oil, carefully cleaned. In addition, cleansing oils are also frequently kept clean.
Bearing maintenance and judgment: in order to determine whether removing bearings can be used, to check after you wash in the bearing.
Maintenance includes: monitor the operation condition, replenishment and replacement of the lubricant, demolished checks on a regular basis, this is the best running of machine maintenance conditions of operational standards, conducted on a regular basis. As a matter of maintenance in operation, there are rotating tone, vibration, temperature, lubricant condition, cylindrical roller bearing split-shaped bearings, rolling elements, the outer of the Raceway surface can be respectively checked.
Check the Raceway surface, scroll bars, status of the mating surfaces, cage wear, SKF bearing clearance increases injury exception and has nothing to do with size precision drop. Non-separation of small ball bearings, the inner ring with one hand supporting level, rotating outer ring to confirm fluency.
