For the use of tapered roller bearings, in the process of maintenance and repair, the disassembly and assembly of bearings is an important link. In many cases, tapered roller bearings will be seriously damaged if improperly installed in the process of installation, resulting in failure to use. Such as bearing small rim fracture fault, this fault is common in the bearing installation of a fault, today to share the cause of small rim fracture caused by improper installation of tapered roller bearings.

 

 

 

1. Installation failure analysis of tapered roller bearings

 

 

 

The tapered roller bearing is made of inner ring, outer ring, cage and 16-grain tapered roller. The tapered roller bearing is made of inner ring, outer ring, cage and 16-grain tapered roller. Among them, the small end of the inner ring showed continuous and spaced fracture, which accounted for about 2/3 of the whole, and the fracture position morphology was "jagged".
