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.
