【摘要】 本文通过金相组织观察、油品分析及对磨屑的扫描电镜分析,认为造成西德MNPJ型单面毛圈圆纬机弯纱三角与织针早期磨损失效的主要原因是所选用的15号工业白油的润滑性能不能满足该机编织毛圈织物时的润滑要求。主要磨损类型是磨粒磨损和疲劳剥落。研究表明,摩擦偶件的显微组织和性能及工况条件的变化,会导致控制磨损的主导磨损类型发生转化。更多还原

【Abstract】 Based on the metallography, oil ( lubrieant) analysis and the analysis of wear seratches and wear chips with SEM, authors found that the maineause which made early wear failure of the stitch can parts and the cylinder needles in the West-Gormany-Made singie jersey circular knitting machine MNPJ was that the libricity of the do mestie white oil NO. 15 did not meet the lubrication requirement of this machine when it knitted plush fabrics. The essential types of the wear were abrasion and fatigle pitting. It was also found that the change of the microstruetures and properties lead the change of the main wear type.更多还原
