Problems solved by technology

[0003] At present, most ships use a single-speed ratio structure to drive the fixed-pitch rudder propeller. If the fixed-pitch rudder propeller is to meet the multi-working conditions requirements of high-tech ships, then the technical parameters such as thrust and speed must be optimized, but the fixed-pitch rudder propeller The blade design can generally only meet the requirements of maximum speed or maximum thrust, and cannot take into account both

Abstract

The invention relates to the field of ships, and discloses a steering oar propelling system and a ship. The steering oar propelling system comprises a speed change mechanism, and further comprises a driving part, a transmission shaft structure and oar blades which are sequentially connected; the speed change mechanism comprises an input shaft, an output shaft, a gear box and a clutch set, and therotating speed ratio of the output shaft to the input shaft is adjusted through cooperation of the gear box and the clutch set; the speed change mechanism is arranged between the driving part and thetransmission shaft structure, the input shaft is connected with the driving part, and the output shaft is connected with the transmission shaft structure; or the speed change mechanism is arranged between the transmission shaft structure and the oar blades, the input shaft is connected with the transmission shaft structure, and the output shaft is connected with the oar blades. The ship comprisesthe steering oar propelling system. According to the steering oar propelling system and the ship, various rotating speed outputs of the oar blades are realized, the requirements of maximum towing force and maximum navigation speed can be met under various working conditions such as towing and navigation, the fuel consumption rate and consumption are low, the navigation speed is high, the time costis saved, and troubleshooting, maintenance and repair are facilitated.

Description

technical field [0001] The invention relates to the field of ships, in particular to a rudder propulsion system and a ship. Background technique [0002] Now high-tech ships are developing in the direction of large-scale, high-ice areas, intelligence, energy conservation and environmental protection, and multi-working conditions. As the key core equipment for main propulsion and dynamic positioning of high-tech ships, the performance of rudder propellers directly affects the usability, reliability and economy of ships. , intelligence, energy saving and environmental protection, and adapt to the direction of multi-working conditions. [0003] At present, most ships use a single-speed ratio structure to drive the fixed-pitch rudder propeller. If the fixed-pitch rudder propeller is to meet the multi-working conditions requirements of high-tech ships, then the technical parameters such as thrust and speed must be optimized, but the fixed-pitch rudder propeller Generally, blade...
