    • An inexpensive rolling bearing is proposed which can be used stably for a long time where the lubricating conditions are severe or bending stresses act. Inner and outer rings of rolling bearings mounted in a rocker arm of an automobile are made of high-carbon chrome bearing steel. They are subjected to heat treatment in which after carbonitriding, high-temperature tempering is carried out. Then they are induction hardened to impart resistance to material quality change and a compressive stress of not less than 200 MPa to the surface layer, thereby markedly improving the rolling contact fatigue life and the tension-compression fatigue strength while keeping the material cost as before. Thus, this bearing can be used stably for a long time even though it is a full complement type bearing, lubricating conditions tend to worsen and the outer ring is repeatedly subjected to bending stress from the cam.
    • 提出了一种便宜的滚动轴承,其可以长时间稳定地使用,其中润滑条件严重或弯曲应力起作用。 安装在汽车摇臂中的滚动轴承的内圈和外圈由高碳铬轴承钢制成。 对它们进行热处理,其中在碳氮共渗之后,进行高温回火。 然后进行感应淬火以赋予材料质量变化的抗性和对表面层的不小于200MPa的压缩应力,从而显着提高滚动接触疲劳寿命和拉伸压缩疲劳强度,同时保持如前所述的材料成本。 因此,即使是满载型轴承,也能够长时间稳定地使用该轴承,润滑条件趋于变差,外圈反复受到来自凸轮的弯曲应力。
