1, EDA bearings subjected to eccentric load
Thin section bearings are generally used to bearing axial load and radial load, the bearing capacity of eccentric load is very limited. If there is an eccentric load applied on the bearing, will cause the bearing load distribution is not reasonable, which dramatically reduces the EDA bearing life, have a fever etc.. Load path under eccentric load.
2, the bearing chamber shape and position tolerance
The bearing chamber shape position tolerance will affect the distribution of thin bearing load, resulting in abnormal load trace.
Load bearing chamber may show traces of roundness deviation, resulting in non load ball also was subjected to the load, thus bearing after operation, there will be heat and noise. If you remove the thin-wall bearings find load path, we need to adjust the roundness of bearing chamber. Form and position tolerance of roundness deviation.
The remaining 3, EDA bearing clearance is too small
In general, thin-wall bearing normal at run time there will always be some residual clearance, these residual clearance will be distributed in non load zone. Effects of residual clearance of rolling bearing life curve. When the residual bearing clearance is too small, will be very easy to be jammed, and thus early failure. The failure of bearing burnt before performance is the noise and heat, and the thin wall bearing load track surface caused by the residual EDA bearing clearance is too small factors may include: the inner ring with the tight inside and outside the ring, the temperature difference is too large. Timely adjustment.
