Analysis of Peeling Failure of Tapered Roller Bearing Roller
The outside diameter surface of a roller of tapered roller bearing peels off in the shape of a straight line.The causes of bearing failure are determined by means of chemical composition analysis,metallographic structure examination and Rockwell hardness inspection.The results show that there are raw material cracks in the outside diameter of that roller.When the bearing is running,the cracks grow under the function of cyclic stresses,finally the roller is peeling.
