Pod propeller capable of generating vertical force

Abstract

The invention discloses a pod propeller capable of generating vertical force, which comprises a pod body and a propeller, wherein the propeller comprises a propeller shaft, a propeller hub and blades.The propeller hub is driven by the propeller shaft to rotate; furthermore, the blades are driven to rotate, the paddle shaft penetrates through the end part of the pod body; a main shaft and a motorfor driving the main shaft to rotate are arranged in the pod body; a brake locking device is arranged at the main shaft; a rotating center ball is fixed in the pod body; a first spherical gear is arranged on the main shaft; a second spherical gear of a hollow structure is arranged at the end, located in the pod body, of the propeller shaft; the first spherical gear is meshed with the second spherical gear; the rotating center ball is nested in the second spherical gear; and a direction controller used for controlling the propeller shaft to swing up and down around the rotating center ball is arranged in the pod body. The angle adjusting efficiency is high, operation is flexible, the structure is simple and compact, and propeller angle adjustment can be achieved on the premise that the overall angle of the motor is not changed.

Description

technical field [0001] The invention relates to a pod propeller, in particular to a pod propeller capable of generating vertical force. Background technique [0002] At present, the propulsion method used in the marine field is mainly the traditional diesel engine shaft propeller, but the low efficiency, high emission, and poor vibration and noise performance of the traditional shaft propeller make it unable to meet the needs of modern green ship construction. With the extensive development of electric motor propulsion technology, electric propulsion has shown significant advantages. Compared with the traditional axial propulsion system, the characteristics of the electric propulsion method are more in line with the requirements of green ship design and construction in terms of environmental pollution control. On the basis of motor technology, people have introduced an electric pod propulsion system, which has successfully broken the traditional propulsion mode of diesel en...

AI Technical Summary

Problems solved by technology

[0003] When a ship sails in wind and waves, it will produce rolling and pitching. However, the existing pod propeller can only generate force in the horizontal direction, which cannot improve the stability of the ship, and it is difficult to meet the needs of some special ship types.
