通过 O形圈农机滚子链和普通滚子链的台架对比磨损试验 ,研究了两种链条的磨损机制 ,微观分析表明 ,对于销轴和套筒铰链摩擦副而言 ,O形圈链条是以疲劳磨损为主 ,伴随着磨粒磨损 ;普通滚子链是以粘着磨损为主 ,伴随着磨粒磨损。对于 O形圈和链板平面摩擦副而言 ,其磨损机制是以疲劳磨损为主。文中也指出了国产O形圈链条质量上存在的问题 Through the comparative wear test of O-ring farm roller chains and ordinary roller chains, the wear mechanism of two kinds of chains was studied. The microscopic analysis showed that for the pin and sleeve hinge friction pairs, the O-ring chain is Mainly to fatigue wear, accompanied by abrasive wear; ordinary roller chain is mainly adhesive wear, accompanied by abrasive wear. For O-ring and chain plane friction pairs, the wear mechanism is mainly fatigue wear. The article also pointed out that the quality of domestic O-ring chain problems
