Available to judge whether the FAG bearings, bearing damage, mechanical properties, the importance of operating conditions, to the next maintenance period.
If the following defects can no longer use must be replaced with new bearings. The inner ring, outer ring, rolling body cage any cracks or gaps.
Ring, rolling body on any fracture.
Scroll Road, face, ribs, rolling on the card hurt.
Cage wear or rivets significant relaxation.
Raceway, rolling rust injury.
Raceway, rolling on a serious indentation and hit marks.
Inner diameter surface or the outer ring outer diameter surface obvious creep.
Heat discoloration apparent.
Enclosed grease the bearings, seals or dust cover damage significantly.
What FAG bearings need to determine fault, and bearing quality is quite good, so the fault is relatively small, but is the best bearing failure, there is no way, as long as there is wear and tear of machinery parts. Let us look at how to determine the fault running bearing. The operation of the bearing failure identification method as follows:
Through the voice recognition:
A wealth of experience through the voice recognition needs. Must undergo adequate training to be able to identify the bearing sound and non-bearing sound. To this end, the person should try to carry out this work. Listening or listening stick attached to the shell can clearly hear the voice of the bearing.
2, the operating temperature to identify:
The method is comparative identification method is limited to use less change in the operation of state occasions. Must be continuous record of temperature, and temperature will rise not only fails, there will be irregular changes. The method and the method of voice recognition and appropriate.
FAG Bearings creep:
The so-called creep refers to the clearance in the bearing mating surfaces, the relative sliding between the mating surfaces. Creep with leaving it emerged mirror bright or dark side, and sometimes with the Card injury produced by wear.
Creep means that we commonly run the outer ring, run the inner inner circle ran, ran cylindrical, running along the inside, running the outer edge, slip, shaft children turn.
CAUSE:
Over the lack of the amount of interference or clearance fit, adapter sleeve fastening is not enough.
Measures to deal with:
Check the amount of interference, the implementation of only transfected measures (deep groove ball bearings, cylindrical roller bearings, cylindrical bore four point angle contact bearings, a one-way bearing, beyond the use of the clutch inner and outer rings with keyway).
Proper fastening the adapter sleeve (aligning ball-aligning roller LNSERTED cone bearing hole).
The accuracy of the shaft and bearing box (bearing mounted in the bearings inside the component).
Axial preload (axial force bearing).
Fastening round the side of the raceway.
Bonding with the surface (such as electrical use, and can also play an insulating effect. Higher) adhesive and center.
To the tie topcoat lubricant (creep can not be resolved, the fear of the FAG bearing wear last resort).
Once you master the above described judgment FAG Bearings are available, you can quickly determine the FAG bearings can continue to use. Thus, the bearing can work more efficiently.
