Jiaxing in processing bearing | bearing ring fracture, crack failure analysis

There is rotational, have HRB bearing ( ) Jiaxing bearing group sales co. , LTD. ( The company) Is bearing group co. , LTD. Established in jiaxing spot sales window, specializing in HRB brand bearings, facing the whole country, the existing stock 50 million yuan, covers the whole bearing, have very strong spot supply, is the group's retail sales center. Bearing in the superfinishing process was conducted few bearing ring fracture, but there will be a lot of crack of set of bearing ring, and in the place has more bearing ring appeared in the process of the crack. This is how to return a responsibility? The author according to the understanding of the bearing ring processing knowledge, to share the bearing ring in the machining process analysis and the reasons of the failure of introduction. 1, bearing ring fracture samples bearing ring fracture failure parts, the first cut a fracture the bearing ring fracture failure sample, to observe the fracture appearance characteristics. Other bearing ring with crack nondestructive testing in the position of the corresponding crack after use marker pen mark sat down, along the marked the location of the sampling, keep will crack is included and happened to be in surface rendering. 2, the results of the macroscopic and microscopic analysis of bearing failure pictures of outer ring fracture scanning electron microscopy (sem), and the steps of enlarge images. It can be seen that the main crack source for the steps of the facade, exists in the facade is more more smooth corrugated area and holes, and on the lower level of two internal cracks are found more obvious. 3, the results ( 1) Cracking of the bearing components of hydrogen induced delayed cracking, belongs to a kind of grinding crack. ( 2) For hydrogen induced delayed fracture this grinding cracking pattern, need to adjust the relevant parameters in the process of grinding, on the one hand, reducing grinding heat as far as possible a large number of accumulation, such as control of a single feeding, etc. ; Is another aspect to consider in cryogenic treatment increase the tempering process, before or after cryogenic treatment promptly carry out higher temperature tempering processing, specific process parameters and progress of research is still needed.
