Abstract

The invention discloses a rudderstock sealing device, and belongs to the technical field of ship rubber system corollary equipment. The sealing device is formed by arranging a packing sealing device, a floating V-type sealing ring sealing device and a sand prevention ring device in a series-connection mode. The packing sealing device comprises packing and a packing gland, the V-type sealing ring sealing device comprises a V-type sealing ring and a V-type sealing ring seat, and the sand prevention ring device comprises a sand prevention ring and a sand prevention ring gland. A fast compressing device of a planetary gear is adopted in the packing sealing device. On the basis of the single packing sealing device, the floating V-type sealing ring sealing device and the sand prevention ring device are added, the risk of water leakage of the sealing device can be effectively reduced, and the sealing device is convenient for personnel to operate after being modified.

Description

technical field [0001] The invention belongs to the technical field of supporting equipment for a ship's rudder system, and in particular relates to a sealing device for a ship's rudder system rudder stock. Background technique [0002] At present, the structure of the existing rudder stock sealing device is a single packing seal, which is prone to water leakage and corrosion of the packing gland and compression studs during the actual ship use; the packing gland is prone to deviation during the compression process Inclined, after water leakage occurs, it is necessary to tighten the compression nut on the packing gland at the same time to compress the packing gland relatively smoothly, which requires high operating skills of personnel. [0003] After retrieval, Chinese Patent No.: 201320790916.2, invention name: rudder stock emergency sealing device, the device of this utility model includes gland (1), gland screw (2), oil seal (3), on the sealing seat (4) An oil seal (3) i...
