Embodiment 1

[0020] Such as figure 1 , figure 2 and image 3 As shown, the present invention relates to a marine pod propulsion device, which belongs to the field of propeller applications. The propulsion device adopts a special modular structure unit type, and the propulsion motor and the full-turn rudder propeller are integrated and designed and assembled. The pod propulsion device separates the modular structure of the pod propulsion device according to functional requirements. The pod propulsion device is divided into a propulsion component 1, a rudder body component 2 and a rudder steering module 3 according to functional requirements, wherein the propulsion component 1 and the rudder body component 2 form a propulsion module. The above-mentioned components or modules can complete functional testing and acceptance relatively independently. The pod propulsion device including the propulsion assembly 1, the rudder body assembly 2 and the rudder steering module 3 and the hull can be...

Embodiment 2

[0028] What is different from the foregoing embodiments is that the propeller assembly 1-2 of the pod may not have a shroud.

Embodiment 3

[0030] The difference from the above-mentioned embodiments is that the propulsion motor housing of the pod can be provided with deflector fins to reduce the water flow resistance.

Abstract

The invention discloses a pod propelling device for a ship. The pod propelling device is composed of a propelling assembly, a rudder body assembly and a rudder rotating module which are designed modularly, the propelling assembly is composed of a propelling motor and a propeller assembly, the rudder body assembly is vertically connected with the rudder rotating module through a lead transition cover at the top end, the rudder body assembly adopts a special structural style convenient to manufacture and machine, and hydrodynamic performance is considered while torque transferring under the rudder rotating working condition is promoted; and the pot propelling device is designed modularly, especially a novel optimizing structure is put forward for the rudder body module part, and a pod propeller with new structure design is simpler in structure and more convenient to mount.

Description

technical field [0001] The invention belongs to the field of marine propulsion devices, in particular to a marine pod propulsion device. Background technique [0002] Pod propulsion device is a new type of marine propulsion device, which realizes the integration of full-turn rudder propeller and propulsion motor. In conventional pod propulsion devices, the propulsion motor adopts a nested structure and is nested in a shell structure similar to a full-turn rudder propeller-with this structure, the motor usually does not need to use a sealed structure, and the motor needs to be arranged with cables The interface with the pipeline, but this also makes the heat dissipation path of the motor longer, and the pipeline layout needs to reserve a place in the nested housing. [0003] In addition, the sleeve-type shell of the pod propulsion motor is connected to the hull and the structure of the rudder shell is usually an inverted "T" or "L" shape. A single-layer "cylindrical" shell ...
