Rotating inner ring and outer ring of the bearing Raceway surface, due to contact with the rolling is scrolling and running track for the dark side, bearing track attached to the roller surface, not fall within the exception, which may be able to tell the load conditions, so in the case of removing bearings, please pay strict attention and observation of Raceway surface running track. If you look at track, you will learn that burden the radial load, subjected to an axial load, tolerance for bearings torque loads, or extreme inequality of rigid on the bearing box. You can check that the bearing is coupled with an unexpected load and install error is large, and be held accountable for clues to the cause of bearing damage.
If you do not select errors and correctly used, prior to bearing life, but for a long time, in this case, damage to split. Bearing on the other hand, there are accidental injury early, and stand up to the early damage, as the reason for the early injury, and consider not enough lubrication, turn, there are foreign bodies penetrated, bearings and shaft deflection, bearing of assembling error, such as the insufficient study of shaft and housing.
A. in order for the Revolution movement stability of cage, should as far as possible the use of guide rings and attention to boot fully lubricated, tapered roller bearings under high speed conditions improved, bearing roller guide l-shaped cage boot Z-ring rib cage instead.
B. bearings rotate at high speed, bearing vibration of its cage Pocket Hole clearance gap small amplitude than Pocket cage vibration amplitude, Pocket Hole gap value is particularly important.
C. should pay attention to minimizing the radial clearance.
D. maintain manufacturing precision as possible, improve the surface quality of cage, bearings in favour of reducing the rolling element and cage the noise generated by collisions or friction.
E. actively adopts advanced cleaning technology, spare parts and products effectively after a thorough cleaning, improving the cleanliness of bearings.
5. scroll through the vibration
When the bearing under a radial load operation, bearing within only several rolling under load, due to contact with elastic rings constitute "Spring" supported keeping the rolling produces periodic vibrations in the line through the radial loads, hinge Center vertically or horizontally to move up and down and prompted noise. Such vibrations called rolling through vibration, more evident especially when running at low speed.
