Full-rotary steering device for controllable-pitch propeller

Abstract

The invention relates to marine equipment, in particular to an improvement to a full-rotary steering device for a controllable-pitch propeller. The full-rotary steering device for the controllable-pitch propeller comprises a steering power device, a speed reducing device driven by the steering power device, and a rotary device driven by the speed reducing device, wherein the speed reducing device is a planetary gear speed reduction unit. The full-rotary steering device has the advantages of compact structure, small size, large transmission power and high transmission efficiency.

Description

technical field [0001] The invention relates to marine equipment, in particular to the improvement of an adjustable-pitch propeller full-turn steering device. Background technique [0002] The adjustable-pitch propeller can rotate the blade through the rotation of the propeller hub under the condition that the speed and direction of the main engine and shafting remain unchanged, thereby changing the pitch angle of the propeller to change the magnitude and direction of the thrust, and adapting to the ship's Requirements such as forward, reverse, stop and speed change, so it is widely used in the propulsion system of ships. The adjustable-pitch propeller can improve the maneuverability of the power plant, and the main engine does not need to change the working conditions frequently, which can make the ship-engine-propeller in a good matching state and improve the propulsion efficiency. And it is easy to realize the automation of operation, which is very beneficial to prolongi...

AI Technical Summary

Problems solved by technology

The full-turn adjustable pitch propeller steering device is mainly composed of a steering power device and a reduction device. At present, the steering power device in the full-turn adjustable pitch propeller steering device mostly uses an electric motor or a hydraulic motor, and the reduction device mostly uses a reduction gearbox. The gearbox adopts multi-stage gear reduction, which is bulky and has low transmission efficiency, which directly leads to a corresponding increase in the power and volume of the steering power device that is matched with it, which not only increases energy consumption and maintenance workload, but also occupies a very limited space on the ship. space

At present, there are not many full-turn adjustable-pitch propeller steering devices with compact structure, small volume, large transmission power, high transmission efficiency, and low energy consumption.
