船舶水润滑尾轴承服役性能研究及其进展

摘要

Research on Water lubricated stem bearing is developing in recent years for the reason that the stem bearing is a key component in ship propulsion shafting system.However,under severe operating conditions,such as low viscosity of the lubricating water,complex load environment (heavy load,edge load and uncertain load),low speed,start/stop operations,sand intrusion,etc.,the stem bearing has complex load carrying mechanism,serious wear,friction noise,etc.Based on characteristics of ship water lubricated stem tube bearing,its performance and prevention mechanism is considered.Research progress in load carrying mechanism and mathematical model,experimental technology,theory of friction and wear and prediction of wear,abnormal friction noise and improvement of performance,are comprehensively reviewed.Problems to be solved and future research directions are demonstrated.%尾轴承是船舶推进轴系的关键部件,近年来水润滑尾轴承的研究有新的进展.在润滑水黏度低、载荷环境复杂(重载、边缘负载和不确定性负载)、低速、启停和沙粒侵扰等恶劣工况条件下,尾轴承的承载机理复杂、磨损严重和摩擦噪声大.从船舶水润滑尾轴承的特点出发,围绕其性能演化与防治机理,就承载机理和模型、试验技术、摩擦磨损机理和预测方法、异常摩擦噪声机理及性能提升措施等五个方面,综合分析船舶水润滑尾轴承的研究进展,指出尚待解决的问题和今后的研究方向.
