摘要/Abstract

摘要： 为了了解织物衬垫在不同的编织工艺下自润滑关节轴承的摩擦磨损机理，采用不同的编织工艺制备了两种聚四氟乙烯(PTFE)/芳纶纤维自润滑编织衬垫，在一定工况下，对两种不同衬垫下的自润滑关节轴承的摩擦学特性进行了研究，并用扫描电子显微镜和能谱仪对衬垫磨损面和对偶面进行了微观分析。研究结果表明：在高频重载条件下，A工艺衬垫（先将两种纤维混并加工成纱线，再将其与芳纶纤维编织成织物）关节轴承的摩擦学性能较差，磨损机理主要是严重的疲劳磨损和粘着磨损；B工艺衬垫（PTFE纤维和芳纶纤维相互交织而成，摩擦面富含PTFE纤维，粘结面富含芳纶纤维）关节轴承则表现出良好的摩擦学性能，相对于A工艺衬垫关节轴承其耐磨性得到提高，磨损机理主要为轻微的粘着磨损和磨粒磨损，可见衬垫的编织工艺在很大程度上影响了关节轴承的摩擦学性能。

Abstract: Two kinds of self-lubricating fabric liner made of polytetrafluoroethylene (PTFE)/Kevlar fiber were prepared by using different weave processes. The tribological properties of self-lubricating spherical plain bearing with two kinds of liners are studied under certain conditions， and the worn surface morpho-logies of the liners and the counterfaces are investigated under a scanning electron microscope (SEM) and an energy dispersive spectrometer (EDS). The results show that spherical plain bearings with the liner A (two kinds of fibers were mixed into the yarn firstly， and they were woven into fabric together with Kevlar fibers) present poor tribological properties under the condition of high frequency and heavy load. The serious fatigue wear and adhesive wear occurred on the worn surfaces of the liner A. However，the spherical plain bearings with the liner B（PTFE and Kevlar fibers were woven into fabric， and the friction surface was rich in PTFE fibers and the bonding surface was rich in Kevlar fibers）present better tribological properties compared with the liner A. And the wear resistance of the self-lubricating spherical plain bearings is significantly improved. Slight adhesive wear and abrasive wear occurred on the worn surfaces of the liner B. So the weave process for the liner has a great influence on the tribological properties of spherical plain bearings. Key
