摘要： PROBLEM TO BE SOLVED: To provide an improved sliding bearing capable of further reducing friction compared with a conventional bearing.
SOLUTION: A plurality of narrow projecting reinforcements 2 are provided on the bearing surface of the sliding bearing 1 along a circumferential direction. When a pitch between the projecting reinforcements is (a), a bottom surface width between the projecting reinforcements is (b) and the width of the projecting reinforcement is (c), a ratio between the bottom surface width (b) and the projecting reinforcement width (c) is set to be b/c>14. The narrow projecting reinforcements formed along the circumferential direction make lubricating oil flowing between the surface of a rotating shaft and the surface of the bearing easy flow in the circumferential direction and make it difficult to flow in the axial direction, and the thickness of the oil film is increased. Further, the projecting reinforcements make the thickness of the main lubrication surface on the side where a gap between the shaft and the bearing is reduced by the act of a load to be thick, and friction is reduced, and oil film pressure is raised, and thus, the projecting reinforcements contribute to the effective increase of a load capacity to the load. By setting the ratio between the bottom surface width (b) and the projecting width (c) to be b/c>14, the friction of the sliding bearing can be further reduced compared with the conventional bearing.

摘要翻译：要解决的问题：提供一种与常规轴承相比能够进一步降低摩擦力的改进的滑动轴承。解决方案：沿着圆周方向在滑动轴承1的支承表面上设置有多个窄突起加强件2。当突出加强件之间的间距为（a）时，突出加强件之间的底面宽度为（b），突出加强件的宽度为（c），底面宽度（b）与突出加强件宽度（c）设定为b / c> 14。沿圆周方向形成的窄凸起加强件使得在旋转轴的表面和轴承表面之间流动的润滑油在圆周方向上容易流动，并且使其难以沿轴向流动，并且油膜的厚度增加了。此外，凸出的加强件使得主轴与轴承之间的间隙的厚度通过负载较厚的作用而减小，摩擦力降低，油膜压力升高，因此，突出的加强件有助于有效地增加负载的负载能力。通过将底面宽度（b）和突出宽度（c）之间的比率设定为b /c≥14，与传统的轴承相比，滑动轴承的摩擦力可以进一步降低。版权所有（C）2007，JPO＆INPIT
