摘　　要：研究油润滑条件下摩托车发动机正时链的磨损特性 ,发现疲劳磨损 ,裂纹的形成和扩展是影响疲劳寿命的主要因素 ;定期刷油或滴油润滑条件下 ,摩托车传动链的磨损机制是磨粒磨损 ,并伴有疲劳磨损 .销轴和套筒零件的渗层及心部组织等是影响链条磨损特性的重要因素 .因为中碳调质钢经碳氮共渗后可获得弥散分布的颗粒状碳化物的表层组织及回火屈氏体的心部组织 ,从而显示出表层耐磨。The main wear mechanism of timing chain under oil lubrication is fatigue wear and the formation and propagation of crack are the dominant factors governing the fatigue life of the chain. That of the transmission chain under periodical lubrication of oil brushing or oil dropping is abrasive wear, accompanied with fatigue wear. The structure and characteristics of carburized layer and center of pin and bush play an important role in governing the wear resistance of the chains. Medium carbon hardened tempered steel after nitrocarburization has well dispersed granulated carbide superficial layer and tempered trooslite core, hence demonstrates the comprehensive mechanical features of high wear resistance, high strength and toughness, and high resistance to plastic deformation.
