[0002] The ship propulsion system is the core component of the ship. Its main function is to provide power for the ship so that it can sail in the water. According to the different power sources and propulsion methods, the ship propulsion system can be divided into many types. The stainless steel swivel is an important underwater component of the ship propulsion system, which plays an important role in sealing oil and water.

[0003] When using a traditional stainless steel swivel, the swivel needs to be directly connected to the propeller blade, and bolts are needed to fix the swivel. The traditional swivel uses non-sinking mounting bolts, which exposes the bolt head and is easily entangled by cables, wire ropes, and fishing nets, thereby damaging the fastening bolts and causing oil leakage. In addition, the inner hole of the original swivel is not hollow, and the inner wall of the swivel fits the tail shaft over a large area, which can easily lead to difficulties in disassembly and maintenance during long-term use.

There are three blades, and three sealing assemblies are respectively installed on the outer wall of the mounting platform.

[0009] As a preferred technical solution of the present invention: the inner cavity of the connecting chamber is communicated with the inner cavity of the sealing chamber, and the inner wall of the sealing shell is in contact with the outer wall of the tail shaft.

[0010] As a preferred technical solution of the present invention: the outer wall shape of the locking plate close to the rotating sleeve body matches the outer wall shape of the fixing bolt, and the inner wall diameter of the hollow inner groove is larger than the inner wall diameter of the rotating sleeve body.

[0011] As a preferred technical solution of the present invention: the outer wall of the locking bolt is threadedly connected to the inner wall of the rotating sleeve body, and the outer wall of the fixing bolt is threadedly connected to the inner wall of the mounting platform.

[0016] 1. The stainless steel swivel sleeve has a hollow inner groove in the inner cavity of the swivel sleeve body, so that the inner wall of the swivel sleeve body cannot be directly connected to the outer wall of the tail shaft in a large area, thereby reducing the contact area between the swivel sleeve body and the tail shaft, making it more convenient to disassemble the stainless steel swivel sleeve, and by embedding the fixing bolts in the inner cavity of the swivel sleeve body, when the tail shaft and the propeller blades rotate, the cables in the seawater are prevented from being entangled with the outer wall of the fixing bolts, thereby better fixing the swivel sleeve body and thus avoiding water and oil leakage.

[0017] 2. The stainless steel swivel sleeve is provided with a locking plate on the outer wall of the swivel sleeve body. After the installation of the swivel sleeve body is completed, the locking plate is installed on the outer wall of the swivel sleeve body, so that the outer wall of the locking block enters the inner cavity of the locking groove, thereby locking the fixing bolt and further preventing the loosening of the fixing bolt. The locking ring is fixed and locked by the locking bolt through the supporting plate provided on the outer wall of the locking plate, so that the locking ring cannot move on the outer wall of the swivel sleeve body, thereby better preventing the rotation of the fixing bolt, thereby better fixing the swivel sleeve body and preventing it from falling off the tail shaft.
