摘　　要：麾擦副进行了抗咬死性能试验研究。试验结果表明:润滑油中磨屑尺寸对滑动摩擦副抗咬死性能有很大的影响.改善润滑油的清洁度能显著提高滑动摩擦副的抗咬死承载能力,滑动摩擦副的抗咬死能力随润滑油中磨屑含量的增加减小很快。观察咬死后试件上的磨痕,表明滑动摩擦副的咬死是由于局部高温引起的接触区熔捍所致。Using a Timken machine, the author has studied experimently the influence of the difference oil - containing particle size on the scuffing resistant of sliding friction pairs.The experiment results show that the particle size has great influence on the scuffing resistant, and the scuffing resistant can increase with the decline of particle size. And the scuffing surface characteristic shows that scuffing is the result of the weld of surface metal.
