摘要

尾轴承是船舶推进系统的重要组成部分,尾轴承材料对轴承的性能起着决定性作用.本文设计并制备了不同配比的愈创树脂-高密度聚乙烯复合材料,对合成的新复合材料和普通高密度聚乙烯材料进行力学性能测试,并比较添加了不同含量的愈创树脂对复合材料的性能影响.在CBZ-1船舶轴系摩擦磨损试验机上对4种材料进行摩擦试验,考察在渐变转速下复合材料的摩擦系数和磨损率.通过分析试验数据,确定了材料混合最佳配比.试验结果表明B型(0.5％愈创树脂)复合材料在力学性能和摩擦性能方面综合性能最好,该研究为该类材料未来在水润滑尾轴承方面的应用提供试验依据.%Stern bearing is an important component of the marine propulsion system. the material of Stern bearing plays a decisive role in the bearing performances. In this study, different proportion of guaiacum-HDPE were designed. Themech-anical properties of new composite materials and the general HDPE material were examined. Moreover, the performancein-fluences on composites of different guaiacum concentrations were compared and analyzed. Wear tests of the four materials were conducted using the CBZ-1 pin-on-disc tester. The friction coefficient and wear mass loss of rubbing pairs wereana-lyzed under the test conditions. By analyzing test data, the optimum material mixing ratio was obtained. The tested results showed that the composite material B (0.5％ guaiacum) had the best comprehensive properties in mechanical properties and tribological performances. This research will provide the experimental basis on the future applications of water-lubricated stern bearing.
