Institutional operation, install bearing parts allows a certain degree of temperature, when you touch body shell with your hand, should not feel hot to normal, rather then SKF bearing temperature is too high.
Bearing high temperature causes are: 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.
SKF bearing allowed light running noise at work, 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. Because of this wear, damaged bearing shells, bearing and shaft fit, 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, SKF bearing lubrication inadequate formation of dry friction and bearings broken produces abnormal noises. After bearing wear loose, loose cage damage, would also have abnormal noise.
1, axle bearing maintenance: in good condition for as long as possible in order to sustain performance bearings, maintenance, overhaul, in order to prevent accidents, it is imperative, ensuring the reliability of operation, increase production, economy.
Maintenance best corresponding mechanical running condition of operational standards, conducted on a regular basis. Content includes monitoring running state, supplementary or replacement of the lubricant, the periodic removal of checks. Overhaul of operational matters, SKF bearings spinning sound, vibrations, temperatures, the lubricants of status, and so on.
2, maintenance of the bearing: bearing cleaning: when removing bearings under overhaul, first record appearance of SKF bearings, confirm that the residual amount of the lubricant, after sampling check of lubricants, and wash bearings. As a cleaning agent, commonly used gasoline, kerosene.
Removed bearing cleaning, cleaning rough and fine cleaning, placed in a container, put the first metal mesh on the bottom, bearing no direct contact with the dirt of a container. Coarse cleaning, if you rotate the bearings with dirt, can damage the bearings of rolling surface, should be noted. In cleaning crude oil, using brushes to remove grease, stickers, generally after a clean, fine wash.
Sperm washing, is rotates the cleaning oil on one side of the bearing, careful cleaning. In addition, cleansing oils are also frequently kept clean.
3, maintenance of the bearing and judgment: in order to determine whether removing bearings can be used, to check after you wash in the bearing. Check on Raceway surface, rolling, the status of the mating surfaces, cage wear, SKF bearing clearance increases and has nothing to do with dimensional accuracy drop damage, the exception. Non-separation of small ball bearings, the inner ring with one hand supporting level, rotating outer ring to confirm fluency.
