The invention discloses a rudder sealing device. The rudder sealing device comprises an installation plate and an installation seat, wherein a plurality of holes connected into a sealing cavity are formed in the upper surface of the installation plate; installation holes are formed in the lower surface of the installation plate; installation holes are further formed in a sealing seat; the sealingseat and the installation plate are fixedly connected through the installation holes and bolts; a sealing assembly is arranged between the sealing seat and the installation plate, and comprises an O-shaped ring I, a spacer ring, a rotary seal and a packing seal; the O-shaped ring I is arranged between the installation seat and the installation plate; a plurality of holes entering the sealing cavity are also formed in the sealing seat; and the hole depth of the sealing cavity adapts to the spacer ring and the rotary seal. According to the invention, by improving the original structure and adding oil holes, lubricating and cleaning are realized, internal garbage is precipitated to carry out self-protection, and the thickness of a gasket is adjusted to adjust different contact areas, so thatthe service life of the rotary seal is prolonged.
