摘要： A method for manufacturing a raceway member, in which a hardness of a region to be plastically deformed is controllable in a stable manner and a sufficient rolling contact fatigue life is ensured by making a hardness of a region including a raceway surface sufficiently high, while suppressing increase in the manufacturing cost, includes a steel member preparation step, a heat treatment step, and a finishing step. The heat treatment step includes: a carbonitriding step, in which the steel member is heated to a carbonitriding temperature, which is a temperature not lower than A1 point, and carbonitrided; a temperature holding step, in which the steel member is cooled from the carbonitriding temperature to a temperature range between not lower than a temperature 100° C. below A1 point and lower than A1 point and is held in the temperature range for not less than 60 minutes and not more than 180 minutes; and a induction hardening step, in which the high hardness region in the steel member including a region to become a raceway surface of the raceway member is induction hardened, without quench hardening of a low hardness region which is a region other than the high hardness region.

摘要： A nitrogen enriched layer is formed in a primary heat treatment, and requenching is conducted in a secondary heat treatment, while the heat treatment efficiency is improved across the entire system. In a primary heat treatment device 1, a bearing component is heated in a heater 11 at a temperature exceeding the A1 transformation point, and is then cooled in a cooler 12 to a temperature less than the A1 transformation point, thus forming a nitrogen enriched layer at the surface of the component. The bearing component that has undergone primary heat treatment is then subjected to high frequency heating in a heater 21 of a secondary heat treatment device 2, at a temperature exceeding the A1 transformation point, and is then cooled in a cooler 22 to a temperature less than the A1 transformation point. Following cooling by the cooler 22, the component is tempered using high frequency heating.

摘要： A roller bearing which can sufficiently ensure an endurance life of rollers even under conditions where debris contamination and temperature rise are large. As the material for an outer ring, inner ring and tapered rollers, a steel in which the Si and-Mn contents are increased is used, and after it has been treated to carbo-nitriding, it is quenched to adjust the amount of retained austenite in the carbo-nitrided layer formed on the surface layer of each part to 20-50 vol %. Thus, it is possible to prevent surface peeling resulting from initiation and propagation of cracks,. thereby greatly improving the endurance life of the rolling bearing under conditions in which debris contamination or temperature rise at bearing portions is large.
摘要翻译：滚子轴承即使在碎屑污染和温度升高的情况下也能充分保证滚筒的耐用寿命。作为外圈，内圈和圆锥滚子的材料，使用其中Si和Mn含量增加的钢，并且在经过碳氮化处理之后，将其淬火以调节残余奥氏体的量在每个部分的表面层上形成的碳氮化层为20-50体积％。因此，可以防止由于裂纹的引发和扩展而导致的表面剥离。从而大大提高滚动轴承在轴承部的碎屑污染或温度升高的条件下的耐久寿命。
