18 fatigue pitting impact bearing troubleshooting when rolling body under load.
In contact with the inside and outside the circle of roller surface contact stress is produced.
Due to internal and external ring and rolling element in the work of relative rotation, so the contact stress is fluctuating.
When the contact stress exceeds limit value, fatigue crack occurred under the surface layer, gradually extended to the surface, lead to internal and external ring rolling body surface fatigue pitting, lead to bearing rotation accuracy loss, noise, shock and vibration.
So the pitting is rolling bearing failure modes.
Who read this article also browse: plastic deformation influence bearing remove invalid way when the rotational speed rate of the rolling bearing is very low or just shake, big load and impact load can make the bearing raceway and rolling body touch caused great part was beyond the ultimate strength of raw materials, will cause a lot of plastic deformation, if the form variables beyond a certain Fan Tian.
Bearing all can't work normally.
And plastic deformation is another invalid way of rolling bearing.
Removed in order to better distinguish between whether the bearing can be repeated use, need to check after the bearing clean, and carefully check the raceway surface, rolling surface, mating surface, ball bearing damage, the improvement of the bearing clearance, and whether there are related to specifications precision reduce damage or abnormal.
Not separation of ball bearing, and then apply inner hole in one hand, rotating determine whether smooth.
