The invention relates to the technical field of ship stern shafts and discloses a large ship stern shaft sealing mechanism. The mechanism comprises a stern shaft sealing box, wherein stern shaft sealing devices are fixedly connected to the left side face and the right side face of the stern shaft sealing box, stern shaft bodies are arranged on the inner sides of the stern shaft sealing devices, and propellers are fixedly connected to the left side faces of the stern shaft bodies; and a stern shaft stable rotating device is arranged on the outer surface of the stern shaft body. According to thelarge ship stern shaft sealing mechanism, the stabilizing transverse plate, the linkage rod, the clamping annular plate, the stabilizing buffer column and the buffer spring are matched with the rotating bearing to clamp and stabilize the stern shaft body, so stability of the stern shaft body during rotation is improved, and the frequency of outward transmission of vibration is reduced; normal useof the stern shaft body is effectively prevented from being affected by damage of the sealing mechanism due to long-time vibration, the service life of the stern shaft body can be prolonged, and useconvenience can be further improved.

    本发明涉及船舶艉轴技术领域,且公开了一种大型船舶艉轴密封机构,包括艉轴密封箱,所述艉轴密封箱的左右两侧面均固定连接有艉轴密封装置,所述艉轴密封装置的内侧设置有艉轴本体,所述艉轴本体的左侧面固定连接有螺旋桨,所述艉轴本体的外表面设置有艉轴稳定转动装置。该大型船舶艉轴密封机构,通过稳定横板、联动杆、夹紧圆环板和稳定缓冲柱、缓冲弹簧配合转动轴承对艉轴本体进行夹持稳定,提高了艉轴本体转动时的稳定性,降低了震动向外传递的频率,有效避免长时间受到震动造成密封机构受损影响艉轴本体的正常使用,有利于艉轴本体使用寿命的提高,有利于进一步提高使用的便利性。
