Description

Technical Field

[0001] The utility model relates to the technical field of propellers, in particular to a deck-assembled fully-rotating propeller. Background Art

[0002] The deck-assembled full-revolving propeller is a marine propulsion unit that integrates the full-revolving propeller with a diesel engine, motor and other driving sources. It has the advantages of compact structure, high maneuverability and easy installation. The whole unit can be directly installed on the deck base, supplemented by a container cover, and can be equipped with lifting and tilting functions. Its vertical height is adjusted by mechanical or hydraulic devices, so that the ship can adapt to larger draft changes and exert maximum thrust, better meeting the immersion depth requirements of propeller blades under different ship loads. If combined with a contra-rotating propeller design, the propeller diameter can be further reduced, adapting to changes in complex waters, optimizing the ballast water treatment system, and improving the economy of the ship.

[0003] However, most of the fully revolving propellers on the deck are currently integrated mechanical meshing structures, which leads to a lot of inconvenience in later maintenance, control and repair, and is cumbersome to disassemble, specifically in the connection between the propeller and the drive structure. When a single fault occurs in the propeller or the drive structure, it cannot be maintained independently and needs to be completely disassembled, especially when the drive motor has a large volume and stroke movement and is overweight, the performance is extremely obvious, and the linkage structure needs to be disassembled synchronously, so as to check the accessories one by one. Therefore, those skilled in the art provide a deck-mounted fully revolving propeller to solve the problems raised in the above background technology. Utility Model Content

[0005] The linkage structure includes a sleeve, a sleeve shaft, an arc-shaped steel part, a propeller coupling, a sleeve groove, helical teeth and meshing teeth. The sleeve shaft is fixedly installed on the output shaft of the driving structure, and a propeller coupling is movably limited and installed in the propeller compartment. A plurality of sleeve grooves are annularly provided on the upper end surface of the propeller coupling and the left end surface of the sleeve shaft, and a movable arc-shaped steel part is provided between the corresponding sleeve grooves on the upper end surface of the propeller coupling and the left end surface of the sleeve shaft for insertion. The arc-shaped steel part slides freely in the sleeve groove, and the output twisting is performed through the driving structure, so that the propeller coupling can rotate freely.

[0006] Preferably, a fully revolving rudder frame is fixedly mounted on the upper end of the propeller seat, and the fully revolving rudder frame is rotated by rotating the positioning of the rudder frame on the ship deck to achieve corresponding rotational drive.

[0007] Preferably, the sleeve is fixedly mounted on the propeller seat via a flange.

[0008] Preferably, the lower end of the propeller shaft is fixedly mounted with helical gears.

[0009] Preferably, the rear end shaft of the propeller is connected to teeth, and the teeth are meshed with the helical teeth to form transmission.

[0010] Technical effects and advantages of the utility model:

[0011] When the utility model is in use, the drive between the sleeve shaft on the driving structure and the propeller connecting shaft on the propeller is movably inserted through the arc-shaped steel part, and the driving structure and the propeller are fixed on the propeller seat by bolts, so that the driving structure and the propeller can be independently disassembled from the propeller seat, thereby simplifying the disassembly work and increasing practicality.
