a pod propeller

Abstract

The invention discloses a pod propeller, which includes a pod body and a propeller, the propeller includes a propeller shaft, a propeller hub and blades, the propeller shaft passes through the end of the pod body, a main shaft and a propeller are arranged in the pod body A motor used to drive the main shaft to rotate. The main shaft is connected to the paddle shaft through a ball cage universal joint. The ball cage type universal joint includes a spherical inner slide at the output end of the main shaft, a spherical outer slide at the end of the paddle shaft and a spherical A rolling ball between the inner slideway and the spherical outer slideway, and a direction control machine for controlling the paddle shaft to swing up and down around the ball cage type universal joint is provided in the pod. The invention has high angle adjustment efficiency, flexible operation, simple and compact structure, and can realize propeller angle adjustment without changing the overall angle of the motor.

Description

technical field [0001] The invention relates to a pod propeller. 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 engine shaft drive. The electric propulsion system combines the pod, col...

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.
