利用摆动摩擦副摩擦磨损模拟试验机,采用单因素试验法,进行不同运行工况(载荷、主轴转速和配合间隙)下连杆衬套往复摩擦磨损试验。对连杆衬套磨损量进行测量,通过磨损量数据分析,结果表明:连杆衬套的磨损量随载荷增大而增大,随主轴转速增大而增大,随配合间隙的增大而减少。 The reciprocating friction and wear test of the connecting rod bushing under different operating conditions (load, spindle speed and mating clearance) was carried out by using the friction and wear testing machine with oscillating friction pair and the single factor test method. The wear amount of the connecting rod bushing is measured and the wear data are analyzed. The results show that the wear amount of the connecting rod bushing increases with the load increasing and increases with the increase of the rotating speed of the main shaft. With the increase of the fitting clearance cut back.
