The invention belongs to the field of stern shaft sealing, and discloses a stern shaft tube sealing mechanism and a stern shaft body thereof.The sealing mechanism comprises a stern shaft tube, a shaft grounding device is arranged above the right side of the stern shaft tube, a standby sealing ring is arranged on the left side of the shaft grounding device, and a connectable closing ring is arranged on the left side of the standby sealing ring; a stainless steel annular spiral spring is arranged between the retaining ring and the O-shaped ring; and the stern shaft sealing system is located on the left side of the retaining ring, and a sealing assembly gasket is arranged on the left side of the stern shaft sealing system. The stern shaft tube sealing system is a water-lubricated shaft sealing system, is made of a material with the highest quality, is longer in service life, is very safe, does not use lubricating grease or oil, is easy to mount and maintain, realizes efficient sealing, can adapt to the movement of a shaft in the axial direction and the radial direction, and is convenient to use. A standby rubber ring is arranged in the front of the shaft sealing assembly, and once the two sides of the connectable closed ring are abraded, the connectable closed ring can be recovered through lathe machining.
本发明属于艉轴密封领域,公开了一种艉轴管密封机构及其艉轴本体,该密封机构包括尾轴管,其右侧上方设置有轴接地装置,所述轴接地装置左侧设置有备用密封圈,所述备用密封圈左侧设置有可连接合环,所述扣环与所述O形环之间设置有不锈钢环状螺旋弹簧;艉轴轴封系统,其位于所述扣环左侧,所述艉轴轴封系统左侧设置有密封组件垫片。该艉轴管密封系统是水润滑的轴封系统,采用最高质量的材料制作而成,使用寿命更长,艉轴轴封系统很安全,不使用润滑脂或油,易于安装维护,实现了高效密封,可以在轴向和径向两个方向上适应轴的运动,在轴上密封组件的前部存有备用橡胶环,一旦可连接合环的两侧发生磨损,可以通过车床加工恢复。
