| 摘要:针对CKS活塞环-合金铸铁缸套配对副,将CKS活塞环与不同材质、珩磨纹角度和表面粗糙度的合金铸铁缸套对磨,通过比较各配对副的摩擦、磨损性能和抗黏着性能,研究CKS活塞环与合金铸铁缸套的匹配规律。研究结果表明:当与CKS活塞环配对时,四种材质缸套的抗黏着性能相近,CuVTi材质的缸套表现出较低摩擦系数和磨损量；缸套珩磨纹角度为40°、表面粗糙度为1μm时,摩擦、磨损和抗黏着性能更优。 |

| Abstract:CKS piston ring had been matched with alloy cast iron cylinder liners of different composition, honing angle and surface roughness. Friction, wear and anti-scuffing properties were compared to study the matching rule of friction pair. The results showed that:when matched with CKS piston ring, the anti-scuffing properties of cylinder liner made of four different materials were similar, and CuVTi alloy cast iron cylinder liner showed a lower coefficient of friction and wear. The honing angle of 40°and surface roughness of 1μm showed better friction, wear and anti-scuffing properties. |
