IKO thin wall bearing load analysis

1, IKO bearings under eccentric load is generally thin wall bearing is used for bearing axial load and radial load, the load eccentricity load capacity is limited. If there are eccentric load imposed on the bearing, will cause bearing internal load distribution is not reasonable, dramatically reducing IKO bearing life, produce the condition such as fever. The load path under eccentric load. 2, bearing chamber shape tolerance of bearing housing shape tolerance of super bad will influence the distribution of thin wall bearing internal load, resulting in abnormal load. Load trace indicates that the bearing chamber may roundness error, causing the load OuDeQiu bear to the same load, bearing such internal after operation, there will be a fever and noise. If remove the thin wall bearing load path found, it needs to adjust the bearing chamber of roundness. Position tolerances of roundness error. 3, IKO bearing clearance is too small in general, the remaining normal thin wall bearing there will always be some remaining clearance at run time, these remaining clearance will be distributed in the load section. Remaining clearance on the curve of the rolling bearing life influence. When the residual clearance through the hours, the bearing will be very easy to stuck, so as to early failure. The performance of these failure bearings burned before is noise and fever, and load on the surface of the thin wall bearing raceway track IKO bearing clearance is too small remaining factors may include: inner ring with tight, inside and outside the circle temperature difference is too big, etc. Should be adjusted in a timely manner.
