The invention relates to the technical field of ship power device systems, in particular to a rear sealing device of a tail shaft, which comprises a wear-resistant bushing, a wear-resistant bushing flange and a propeller hub front end face are connected through bolts, and the wear-resistant bushing flange is arranged on the outer circle of a tail shaft in a sleeving mode; a body which is of a cylindrical structure, a connecting flange used for being connected with the rear end of the tail pipe in a sealed mode is arranged at one end of the body, and an annular space is formed by an inner hole of the body and the outer circle of the abrasion-resistant lining; the front packing filler and the rear packing filler are located at the front end and the rear end in the annular space correspondingly and arranged at intervals in the axial direction. And the muddy synthetic filler is filled between the front packing filler and the rear packing filler in the annular space. The marine oil lubrication tail shaft sealing device is used for solving the worldwide problems that an existing marine oil lubrication tail shaft sealing device is prone to abrasion and damage to leak oil, and the sealing device must be repaired or replaced by docking or pressing a head, lifting a tail and pulling a tail shaft once the oil leaks.

    本发明涉及船舶动力装置系统技术领域,具体涉及一种尾轴后密封装置,其包括:耐磨衬套,耐磨衬套法兰与螺旋桨桨穀前端面采用螺栓连接并套设置在尾轴外圆;本体,本体为筒形结构,并且本体的一端设有用于与尾管后端部密封连接的连接法兰,本体的内孔与耐磨衬套的外圆形成一环形空间;前置盘根填料和后置盘根填料分别位于环形空间内的前后两端,并沿轴向间隔设置;泥状合成填料填充于环形空间内的前置盘根填料与后置盘根填料之间。本发明用于解决现有船舶油润滑尾轴密封装置易磨损、损坏而漏油,并且一旦漏油就必须上坞或压头抬尾抽拉尾轴对密封装置进行修理或更换这一世界性难题。
