The data analysis of the rolling bearing is as follows: the ferrule and the rolling body of the rolling bearing; one side repeatedly receives the high touch pressure; one side carries the tumbling touch with the sliding. The adherer; one side and the ferrule and the rolling body are both sides; or one of them slides Touch; one side receives tension and compression. Therefore; the ferrule of the bearing; the information, function, and primary requirements of the roll and the holder are as follows.
The functions required for the ferrule and roll body data: high rolling fatigue strength, high hardness and high wear resistance.
The functions required by the data are adhered to: the dimensional stability is good, the mechanical strength is large, and the processing is good. It is not the same according to the use; the impact resistance, heat resistance and corrosion resistance are also required.
Information on ferrules and tumbling bodies: ferrules and tumbling bodies are usually made of high-carbon chrome bearing steel. Most of the bearings; using JUJ steel in the JIS steel grade. The large-sized bearings use the chemical composition of SUJ3.SUJ2; in various countries around the world; as bearings The data has been normalized. For example, it is the same kind of steel as AISL52100 (USA), DIN100Cr6 (West Germany), BS535A99 (UK).
Further demand for impact resistance; use of chrome steel, chrome molybdenum steel, nickel chrome molybdenum steel as the bearing data, quenching by carburizing; make the steel from the appearance to the appropriate depth has a hardened layer. With appropriate hardening depth, fine Arrangement, suitable for the appearance of hardness and the hardness of the carburizing bearing; the bearing has better impact resistance than the bearing bearing steel; the chemical composition of the steel for ordinary carburizing bearings.
Vacuum degassing was implemented; therefore; the data used were high in cleanliness, low in oxygen content, and good in quality. The appropriate heat treatment was selected; the life of the rolling tumbling of the bearing was significantly improved.
In addition to the above steel grades; based on special use; also use high-speed steel with excellent heat resistance; stainless steel with good corrosion resistance.
Persistence of information: stamping and holding materials; using low-carbon steel. It is not the same as the use; also using brass plates, stainless steel plates. Cutting the data of the frame; using high-strength brass, carbon steel; Use synthetic resin.
