That is, for example, a bar of high carbon chromium bearing steel is forged into a donut shape while being LF-shrinked at a temperature of approximately 11') 0"C, and then cut from the bar at a temperature of 700 mm.
Annealing is performed at 930'C to 800°C for 20 hours, leaving it for 10 hours at room temperature in the middle, and if the bar material is a joint steel such as chromium molybdenum steel, it is normalized at 930'C and 800°C.
The precipitated phase is spheroidized with C. Next one side end face and outer diameter,
Cutting the R-shaped groove on the other side end face and inner diameter by copying, followed by marking, quenching and tempering, and finally rough finishing of both ends, outer diameter, inner diameter, and R-shaped groove. , super finishing. Some parts (C) are cut from bar materials, but in any case, the number of processing steps from supplying the bar material to completing the inner ring or outer ring is extremely large, and generally the material cost ratio 1 in the product cost is 10-25%
It is said that Furthermore, the mechanical equipment used for these processing operations is also very large, complex, and expensive.

とは容易に理解されるであろう。Pressure molding is performed using a molding machine equipped with the unit, and then the temperature is 1000°C to 1200°C in a sintered product consisting of a preheating section, a heating section, and a cooling section.
Complete the sintering at a temperature of °C. It goes without saying that an atmosphere is constantly flowing to prevent the oxidation of the green compact using a reducing gas such as ammonia decomposition gas or petroleum-based metamorphosed gas.
゛The method for manufacturing the hard lining 3 is similar to that described in the prior art when using high carbon chromium bearing steel or carburized alloy steel, and can be obtained with small-scale equipment, or when using tungsten carbide, carbide When using titanium or ceramics, it can be manufactured by a known method. It will be easily understood that the outer ring of the bearing shown in FIG. 1(b) can be manufactured by the same method as the inner ring shown in FIG. 1(0) described above.

できる。Effects of the Invention Instead of manufacturing the inner and outer rings of bearings using a single high-grade metal that requires a large number of man-hours, such as forging and cutting with large and complex machinery, this new method requires particularly wear resistance. Since only the lining is made of high-grade material and the portion in contact with the shaft or hole is made of low-grade material by one-shot molding and sintering, the material costs for the inner, upper, and outer rings can be reduced.

ができる。When using high carbon chromium bearing steel or carburizing alloy steel as the lining, the process from starting the material to finishing it into a ring shape is similar to conventional technology, but the material cost is lower than that of conventional products, so for example, smaller sizes are used. After molding, it is possible to expand the diameter while improving the strength to a desired size by roller rolling, and since the power required to process the product can be reduced, the cost of machinery and equipment and processing can be reduced.
