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. The mechanical properties of new composite materials and the general HDPE material were examined. Moreover, the performance influences 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 were analyzed 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.
