The self-balancing type tail shaft lubricating and sealing system comprises a self-balancing air cylinder, the interior of the self-balancing air cylinder is divided into an oil cavity and a water cavity through an isolation sliding plug, and the isolation sliding plug can move in the axial direction of the self-balancing air cylinder; the oil cavity is filled with lubricating oil and connected with a front sealing device and a rear sealing device through pipelines, and the front sealing device and the rear sealing device comprise a plurality of sealing rings acting on the tail shaft. And the water cavity is communicated with outboard seawater through a pipeline. The complexity of the tail shaft lubricating oil system is greatly simplified, the reliability and maintainability of the system are improved, meanwhile, the construction cost, the weight of the system and the maintenance technical requirements are reduced, and many technical problems and defects of the technical scheme of an existing tail shaft lubricating oil system of a large semi-submerged ship are mainly solved.

    本发明提出了一种自平衡式尾轴润滑密封系统,包括自平衡气缸,自平衡气缸内通过隔离滑塞分为油腔和水腔,隔离滑塞能够沿自平衡气缸的轴向运动;油腔内充满润滑油,油腔通过管路连接有前密封装置和后密封装置,前密封装置和后密封装置包括若干作用于尾轴上的密封环;水腔通过管路与舷外海水连通。本发明大大简化了尾轴润滑油系统复杂性,提高系统的可靠性和可维护性,同时也降低的建造成本、系统重量和维护技术要求,主要解决了大型半潜船的现有尾轴润滑油系统的技术方案的诸多技术问题和不足。
