What are the reasons for the double row self-aligning roller bearing wear fault, how to eliminate
The damage state about imported bearings such as card wound roller bearing rings, flanges, may consider as reasons, lack of lubricant, not suitable for defects, foreign invasion, oil discharge structure of double row self-aligning roller bearing mounting deflection error, the shaft is too large, also for these reasons coincide.
Operating conditions, such as installation conditions, speed, axial load, direction, magnitude, etc..If the correct use of double row spherical roller bearing, can be used to reach fatigue life. But accidents can happen prematurely and can't be used. This early damage, relative to the fatigue life, is the quality limit for what is called a fault or an accident. Due to the lack of attention in installation, use, lubrication, foreign invasion of foreign bodies, the study of the thermal effects of shafts and shells is inadequate.
Determine the design parameters of double roller bearing structure stiffness, flexibility, quality, vibration damping system made in operating conditions will have to adapt its mechanics.The vibration caused by the deviation in the process of bearing manufacturing, the smaller the deviation, the smaller the vibration. The ball surface roundness, waviness and surface roughness is the most important factor on the vibration of the bearing parts, the shape error and the surface of inner ring and outer ring raceway roughness, again is the double row self-aligning roller bearing cleanliness and lubricant quality etc..
