水润滑橡胶尾轴承在低速、重载、润滑不良状况下,会出现异常振动与鸣音,影响舰船的隐蔽性与生存能力以及乘员的舒适性.目前,对尾轴承鸣音既无法进行预估;也无法在事后予以有效的消除.为此,从尾轴承鸣音产生机理、影响因素以及抑制技术等方面进行了探讨和分析.认为应充分考虑各种因素的影响,结合试验和先进的分析手段开展综合研究,在此基础上,制定详实的水润滑尾轴承设计、制造、安装规范,提高舰船尾轴承的使用性能,达到减振降噪的目的.

Bearing noise or abnormal vibration sometimes originates in water-lubricated rubber stern bearings in marine propeller shaft systems due to operation at low-speed, overloading and poor lubrication conditions. It will affect the comfort of ships, and especially destruct the hidden nature and viability of submarines. Currently, the bearing noise can be neither predicted nor eliminated effectively. Therefore studying the mechanism of stern bearing noise has important theoretical and practical significance. In this paper, research advances of noise generation mechanism, influencing factors and vibration beep suppression technique were reviewed. It is pointed out that a comprehensive study, considering various influencing factors and combining advanced analysis means and testing methods, is necessary. On this basis, detailed design, manufacture, and installation specifications can be developed, bearing performance can be improved and bearing vibration and noise can be reduced.
