摘 要: Water-lubricated rubber bearing (WLRB) often operate in mixed lubrication. Friction and wear are their common failure modes. In present study, the tilting-pad structure is employed to improve the conventional WLRB. A mixed lubrication model of water-lubricated rubber tilting-pad journal bearing (WLRTPJB) is developed to reveal the mixed elastohydrodynamic (Mixed-EHD) performance. The influence of structure and operating parameters on the tribological properties and pad swing characteristics are studied. The results show a lower contact load of a WLRTPJB, especially under heavy load conditions. The studies also give the optimum pivot offset and preload factor that can minimize the contact pressure. Moreover, the equilibrium tilting-pad angle is sensitive to changes in design and operating parameters. This study would provide certain guiding significance for design optimization of WLRB.

水润滑橡胶轴承(WLRB)通常在混合润滑状态下运行,摩擦和磨损是其常见的失效模式。本研究采用倾角垫片结构改进传统WLRB,建立了水润滑橡胶倾角垫片轴向推力轴承(WLRTPJB)的混合润滑模型,以揭示其混合弹性流体动力学(Mixed-EHD)性能。研究分析了结构及运行参数对摩擦学性能和垫片摆动特性的影响。结果表明,WLRTPJB的接触载荷较低,尤其在重载条件下表现更优。研究还确定了能够最小化接触压力的最佳支点偏移量和预紧因子。此外,平衡倾角垫片角度对设计参数和运行参数的变化较为敏感。本研究为WLRB的设计优化提供了一定的指导意义。
