The number of the rudder blades is multiple, and the rudder blades are uniformly distributed on the outer side of the shell in the circumferential direction and used for controlling the integral navigation depth, the integral heading and the integral rolling. Each rudder blade drives the rudder blade to rotate through the torque transmitted by the steering engine and the rudder shaft, and all the steering engines are arranged inside the shell. The lower end of the rudder shaft is connected with the rudder blade, and the rudder shaft and the rudder blade are integrally processed. The upper end of the rudder shaft penetrates through the shell and the lubricating gasket respectively and then is connected with the rudder shaft sleeve, the cylindrical structure of the inner cavity of the rudder shaft sleeve is consistent with the cylindrical structure of the upper end of the rudder shaft, and the outer diameter of the rudder shaft sleeve is larger than that of the rudder shaft hole of the shell.

Two annular grooves with different sizes are arranged at the position of the rudder shaft hole on the shell and are respectively used for installing a rotary check ring and an O-shaped sealing ring.
According to the magnitude of the transmission torque, the inner cavity of the rudder shaft sleeve 8 can be selectively processed into polygonal columnar structures such as quadrangle, hexagon, octagon and the like, and the upper end of the rudder shaft 2 is processed into a corresponding polygonal columnar structure to be tightly matched with the polygonal columnar structure, so that the torque can be reliably transmitted. The upper end face of the rudder shaft 2 is provided with a threaded hole, the rudder shaft sleeve 8 is provided with a corresponding countersunk hole, and the upper part of the rudder shaft sleeve 8 is connected with the rudder shaft 2 through a countersunk screw 9, so that the rudder shaft 2 is tightly attached to the rudder shaft sleeve 8, and the torque is stably transmitted. The shape of the rudder shaft sleeve 8 can also be selectively processed into polygonal columnar structures such as quadrangle, hexagon, octagon and the like.
The examples of the invention are given below:
the rudder shaft sleeve in this embodiment adopts a hexagonal columnar structure, and is installed in cooperation with the steering gear driving mechanism groove, and the rudder shaft sleeve 8 is completely embedded into the steering gear driving mechanism groove, so that the axial installation space can be saved, the structure is compact, and the disassembly is convenient.
The structure realizes effective torque transmission by closely attaching the side surfaces of the inner polygonal columnar structure and the outer polygonal columnar structure, and realizes the tight connection of the rudder shaft 2, the rudder shaft sleeve 8 and the steering engine driving mechanism by screw fastening and axial dimension limiting to ensure reliable torque transmission.
