The invention relates to an opening and closing dual-purpose water lubrication heat preservation system for a water lubrication bearing of an icebreaker, and belongs to the technical field of ship design and manufacturing. A front stern bearing and a rear stern bearing respectively sleeve the front and the rear of the stern shaft, and a passage for circulating lubricating water is arranged between the front stern bearing and the rear stern bearing; the closed water lubrication heat preservation system comprises a cooling fresh water tank and a seawater tank, the front stern bearing is connected with the cooling fresh water tank and the seawater tank, and a heating device is arranged in the cooling fresh water tank. The closed water lubrication heat preservation system has the advantages of being renewable, free of pollution and corrosion, capable of being repeatedly used, extremely small in environmental disturbance and the like. According to the system, the stern bearing can be lubricated through fresh water, the good lubricating performance of the water-lubricated bearing can be better guaranteed in the polar region environment, and due to the system design that closed heat preservation fresh water lubrication and open seawater lubrication are combined, the reliability of the water-lubricated bearing is effectively improved.

    本发明涉及一种用于破冰船水润滑轴承的开闭两用式水润滑保温系统,属于船舶设计及制造技术领域。艉轴前后分别套设有前艉轴承和后艉轴承,前艉轴承和后艉轴承之间设有用于润滑水流通的通路;闭式水润滑保温系统包括冷却淡水舱和海水槽,前艉轴承分别与冷却淡水舱和海水槽连接,冷却淡水舱中设有加热装置。本发明提供的闭式水润滑保温系统具有可再生、无污染、无腐蚀、能反复使用以及对环境扰动极小等优点。该系统既可以通过淡水对艉轴承进行润滑,在极地环境下更能确保水润滑轴承的润滑性能良好,又由于是闭式保温淡水润滑和开式海水润滑相结合的系统设计,有效提高了水润滑轴承的可靠性。
