研究了由PEEK环-PTFE（聚四氟乙烯）/石墨保持器-氧化铝球组成的PEEK（聚醚醚酮）复合固体润滑膜对混合径向聚合物轴承寿命的影响，研究了自润滑性能。在干燥条件下滚动接触时，PEEK环赫兹接触区域的“纯滚动接触”轨道周围形成PEEK/石墨薄膜层，然后覆盖整个接触轨道。 PEEK/石墨薄膜的生长保持了轴承的平稳旋转，避免了卡住。 PEEK 环上的微槽强烈影响 PEEK/石墨膜的形成。这一结果有助于聚合物轴承微凹槽的有效摩擦学设计。
The influence of PEEK (Polyether ether ketone) composite solid lubricant film on hybrid radial polymer bearing life, consisting of PEEK ring-PTFE (polytetrafluoroethylene) /graphite retainer-alumina balls, was investigated in terms of self-lubrication properties. A PEEK/graphite film layer formed around the ‘pure rolling contact’ track in the Hertzian contact area of the PEEK ring during rolling contact under dry conditions, and then covered the whole contact track. The PEEK/graphite film growth maintained smooth rotation of the bearings, avoiding seizure. Microgrooves on the PEEK ring strongly influenced the formation of PEEK/graphite film. This result helps effective tribological design of micro grooves for polymer bearings.
