The main factors affecting rolling tapered roller bearings are:?

1. Metal peeling on the raceway surface
The rolling body of the tapered roller bearing and the raceway surface of the inner and outer rings bear the action of periodic pulsating load, resulting in periodic contact stress. When the number of stress cycles reaches a certain value, fatigue peeling will occur on the working surface of the rolling body or the inner and outer ring raceways. If the load of tapered roller bearing is too large, this fatigue will be aggravated. In addition, improper installation of tapered roller bearing and bending of shaft will also cause peeling of raceway. The fatigue peeling of the tapered roller bearing raceway will reduce the running accuracy of the shaft and cause vibration and noise of the mechanism.
Burn of tapered roller bearing
Burned tapered roller bearings have flashback color on their raceways and rolling bodies. Burns are generally caused by insufficient lubrication, unqualified or deteriorated lubricating oil quality, and tight assembly of tapered roller bearings.
3. Plastic deformation
Uneven pits appear on the raceway and roller contact surface of the tapered roller bearing, indicating that the tapered roller bearing has plastic deformation. The reason is that the local stress of the working surface of the tapered roller bearing exceeds the yield limit of the material under the action of a large static load or impact load, which generally occurs on the tapered roller bearing with low speed rotation.
4. Cracks on tapered roller bearing race
Cracks in the tapered roller bearing race may be caused by the tight fitting of the tapered roller bearing, the looseness of the outer or inner ring of the tapered roller bearing, the deformation of the conical roller bearing envelope, and the poor surface processing of the installed tapered roller bearing.
5. The cage is broken
The reasons are insufficient lubrication, broken rolling body, seat ring skew, etc.
6. The metal of the cage is adhered to the rolling body
The possible cause is that the rolling element is stuck in the cage or the lubrication is insufficient.
7. The race raceway is severely worn
There may be foreign matters falling into the seat ring, insufficient lubricating oil or improper lubricating oil grade.
The main factors affecting the rolling tapered roller bearing are: load, lubrication, assembly, environmental conditions, material or manufacturing accuracy, etc.
