The invention relates to the technical field of ship manufacturing, in particular to a stern tube sealing adjusting structure and a stern tube sealing adjusting method. A stern tube sealing adjusting structure applied to the stern tube sealing adjusting method comprises an adjusting ring, a sealing assembly, a stern tube and a propeller shaft, the stern tube is provided with a containing through hole extending in the axial direction, the propeller shaft is in clearance fit with the containing through hole, and a groove spigot extending inwards in the axial direction is formed in the end, close to the outside in the axial direction, of the containing through hole. The sealing assembly is used for sealing the stern tube and the propeller shaft, the inner diameter of the adjusting ring is adjustable, the sealing assembly is provided with a flange spigot, the adjusting ring is clamped between the flange spigot and the groove spigot in the radial direction, the adjusting ring is clamped between the groove spigot and the sealing assembly in the axial direction, and sealing assembly of the stern tube and the propeller shaft is achieved. And the sealing assembly and the propeller shaft are coaxially assembled.

    本发明涉及船舶制造技术领域,尤其涉及艉管密封调节结构及艉管密封调节方法。本发明提供的艉管密封调节方法所应用的艉管密封调节结构包括调节环、密封组件、艉管以及螺旋桨轴,艉管具有沿轴向延伸的容置通孔,螺旋桨轴与容置通孔间隙配合,容置通孔沿轴向靠近外部的一端设置有沿轴向向内延伸的凹槽止口,密封组件用于密封艉管与螺旋桨轴,调节环的内径可调,密封组件具有凸缘止口,调节环沿径向夹设在凸缘止口与凹槽止口之间,且调节环沿轴向夹设在凹槽止口与密封组件之间,实现了艉管与螺旋桨轴的密封组装,且保证使密封组件与螺旋桨轴同轴心装配。
