|
摘要
为了改善缸套-活塞环的摩擦性能,通过激光刻蚀技术在活塞环工作面加工出不同形状的表面织构。在同一转速、不同载荷下通过微机控制的往复式摩擦磨损试验机研究不同表面织构活塞环对缸套-活塞环摩擦学性能的影响。试验结果表明:在载荷为400 N工况下,活塞环的椭圆、圆形、方形织构摩擦系数分别可以降低1.1%、18.3%、14.1%;载荷600 N工况下,3种织构分别可以降低35.3%、35.3%、19.1%;综合分析摩擦系数、表面形貌、接触电阻,圆形凹坑织构的活塞环在降低摩擦系数、提高油膜润滑状态等方面效果最优。
In order to improve the friction performance of cylinder liner piston ring,the surface textures of different shapes were machined through laser etching technology. Under the same rotational speed and different applied loads,the influence of the piston rings with different surface textures on the tribological performance of cylinder liner-piston ring was studied with a computer-controlled reciprocating friction and wear tester. The experimental results show that the friction coefficients of elliptical,circular and square textures of piston rings reduced by 1.1%,18.3% and 14.1% respectively at a load of 400 N,and 35.3%,35.3% and 19.1% at a load of 600 N respectively.Through the comprehensive analysis of friction coefficient,surface topography and contact resistance,the piston ring of circular pit texture has the best performance in reducing the friction coefficient and wear and improving the lubrication condition of oil film.
