摘要: 缸套表面的不同纹理结构对柴油机缸套-活塞环摩擦副性能有较大影响,从而影响到柴油机的使用寿命、可靠性及经济性等。为提升缸套-活塞环摩擦副的摩擦学性能,利用不同种类表面纹理(横竖槽、环圆槽、环方槽)缸套在同一转速、不同载荷下进行试验来获取摩擦特性数据,得到不同纹理缸套的摩擦特征参数有显著不同。通过对各种不同表面纹理缸套的摩擦特性分析,得出了环方槽缸套更适合于在低载荷下运行,而横竖槽缸套更适合在中载荷、高载荷下运行。

Abstract: The different surface textures of cylinder liner has a significant effect on the performance of diesel cylinder liner-piston ring friction pairs, thus affecting the service life, reliability and economy of diesel engine. In order to improve the tribological properties of cylinder liner-piston ring friction pairs,the cylinder liners with different surface textures are test to obtain the friction characteristic data under the conditions of same speed and different loads. The tset results show that the friction characteristic parameters of cylinder liner are obviously different. The tribological properties of cylinder liners with surface textures under different running conditions are compared and analyzed. It is concluded that the cylinder liner with annular square groove is more suitable to run under low load, while anyway tank is more fit to run under medium and high loads. Key
