The tapered roller bearing in the following example suffered early failure during use. After disassembly, it was found that the bearing assembly was highly abnormal, the rolling element surface was severely peeled off, and a large amount of flaky debris was visible after cleaning.
1. After the tapered roller bearing fails, the characteristics of each part failure:
1.1 Tapered roller bearing outer ring
The raceway surface of the outer ring is on a normal working track, with slight peeling, and there are friction marks of relative sliding on the outer diameter surface.
2. Bearing failure analysis
The measurement data of the surface condition and related parameters of the faulty bearing can be analyzed as follows:
2.1 The size of the raceway of the inner ring of the bearing changes greatly, and at the same time the inner diameter of the inner ring of the bearing becomes larger;
2.2 The entire running track of the raceway surface of the bearing inner ring has obvious boundaries. Track scratches and peeling are caused by hard foreign matter mixed in the lubricating oil and caused by the high-speed rolling of the rollers.
of;
2.3 There are traces of friction between the inner surface and the shaft, which account for 4/5 of the entire inner diameter width. The inner ring of the bearing and the shaft should be an interference fit. There should be no mutual rotation during normal operation; if there are traces of rotation, It means that there is mutual movement between the inner ring of the bearing and the shaft, and the bearing is working abnormally;
Our company integrates the advantages of technology and talents that can design various different types of High Precision Stainless Steel Standard Stable Performance Single Row or Double-Row Thrust Tapered Roller Bearing according to the different needs of customers in different industries.
