 海洋磨损环境下的船舶水润滑轴承 周潇然 （武汉理工大学，能源与动力工程学院，交通运输工程1405班，学号1049721402056） 摘要:自20世纪70年代出现石油资源危机和近年来人们对环境保护的重视, 水润滑轴承开始逐步推广应用。用水代替油作润滑介质, 不仅节约大量的油料, 还可以避免以油为润滑介质对环境造成的污染。同时水润滑轴承成本低, 阻燃性好, 易维护保养, 还能降低摩擦副的摩擦、磨损、振动、噪声、无功能耗等关键问题。因而水润滑轴承的研究对于提高机械效率和保护环境等都有着重要的理论研究和应用价值。本文在整个海洋磨损的大环境下，对船舶水润滑轴承的结构以及润滑机理进行了详细介绍，并比较了各类水润滑材料的优缺点，重点介绍了水润滑橡胶轴承的突出特点以及良好应用。 关键词：橡胶轴承 水润滑 润滑 Water lubricated bearing of the ship in the Marine abrasion environment (Wuhan University of Technology,School of Energy and Power Engineering) Abstract:since the 1970 s oil crisis and peoples emphasis on environmental protection in recent years, the water lubricated bearing began to gradually popularization and application. Water instead of oil lubrication medium, not only save a lot of oil, also can avoid to oil for lubrication medium pollution to the environment. At the same time water lubricated bearing low cost, good flame retardant, easy maintenance, still can reduce the friction pair of friction, wear, vibration and noise, no key problems such as function loss. The water lubricated bearing research for the improvement of mechanical efficiency and protect the environment and so on all has important theoretical and application value.In this paper, under the circumstances of the whole Marine abrasion, the structure of ship water lubricated bearing and the lubricating mechanism are introduced in detail, and compares the advantages and disadvantages of all kinds of water lubrication material, mainly introduces the outstanding characteristic of water lubricated rubber bearings and good application. Keywords: rubber bearing, water lubrication, mechanism of lubrication, 1 绪论 1.1本文研究和意义 [1]。 由于水具有无污染、来源广泛、节省能源、安全等特性，是最具有发展潜力的工作介质。因此，为了降低或减少各种摩擦副因运动而产生的摩擦、磨损、振动、冲击、噪声、无功能耗，解决可靠性差和寿命较短等问题，节省大量油料和贵重有色金属等战略资源，净化和保护江河湖水资源等人类赖以生存的环境，利用水替代矿物油作为工作介质的水润滑轴承，成为高效节能与环境保护科学研究领域的前沿，已引起了人们的普遍关注。 水润滑轴承是以水作为润滑介质，而传统的油润滑尾轴承则是以润
