Problems solved by technology

[0005] The purpose of the present invention is to solve the problem that current fixed-pitch propellers cannot meet the requirements of fire pumps, generators and other equipment to work at rated speeds, and in azimuth propellers whose blade pitch can be changed, it is difficult to monitor the underwater blade pitch. The actual situation, providing a new adjustable pitch azimuth propeller for ships

Embodiment Construction

[0020] Depend on figure 1 and figure 2 It can be seen that the adjustable pitch azimuth propeller for ships includes: box body, input shaft 1, hydraulic clutch 2, transmission shaft 3, upper spiral bevel gear 4, lower spiral bevel gear 13, slewing support, rudder steering hollow column 10, middle Vertical shaft 11, paddle shaft 14, variable pitch paddle hub mechanism 15, paddle blade 16 and hydraulic control mechanism 19, wherein: the steering hollow column 10 is connected with the rotary support 8 on the well box body 7 through the cone body 9, and the middle vertical shaft 11 is located at In the steering hollow column 10, the blade pitch feedback mechanism 21 is located between the inner wall of the steering hollow column 10 and the outer wall of the intermediate vertical shaft 11, and is installed on the inner wall of the steering hollow column 10. The oil pipe is the sampling point, and the feedback information is transmitted to the engine room above the deck.

Abstract

The invention relates to a marine adjustable-pitch all-direction propeller comprising a box, an input shaft, a hydraulic clutch, a transmission shaft, an upper spiral bevel gear, a lower spiral bevel gear, a rotary support, a steering hollow column, a middle vertical shaft, a propeller shaft, a variable pitch hub mechanism, blades, and a hydraulic mechanism. The steering hollow column is connected with the rotary support on the box through a cone. The middle vertical shaft locates in the steering hollow column. A blade pitch feedback mechanism locates between the inner wall of the steering hollow column and the outer wall of the middle vertical shaft and is mounted on the inner wall of the steering hollow column. By using an inner oil pipe of the propeller shaft as a sample point, the blade pitch feedback mechanism feeds back information to a cabin above the deck.

Description

technical field [0001] The invention relates to an azimuth propeller with variable blade pitch. The ship can adjust the thrust of the ship by changing the blade pitch without changing the speed of the main engine. The main engine can also be equipped with a fire pump, a generator, etc., fully Take advantage of host power. The ship equipped with the propeller of the present invention has more flexible operation, more functions, compact cabin layout, sufficient fuel oil for the main engine, energy saving and emission reduction. Background technique [0002] At present, ship propellers are the core components of ship power equipment, and azimuth propellers are widely used in port tugboats, fire boats, work boats (crane ships, scientific research ships, open-body mud barges, etc.), ferries and many other fields , the azimuth propeller can rotate 360° in any direction through the slewing mechanism, integrating the functions of propulsion and steering, so that the ship can obtain...
