CKS活塞环与合金铸铁缸套匹配规律研究

Matching Rule of CKS Piston Ring with Alloy Cast Iron Cylinder Liner

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。

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 antiscuffing 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.
