Description

Novel annular propulsion structure for electric ship

Technical Field

The utility model relates to the technical field of electric ship recommendation systems, in particular to a novel annular propulsion structure for an electric ship, and particularly relates to a mechanical connection structure of the novel annular propulsion structure.

Background

The traditional electric ship mostly adopts shaft type propulsion, uses a motor with low rotating speed and large torque to replace an engine and a speed reducer of the traditional fuel ship, and also needs a special rudder system to support the steering of the ship; this makes the overall structure quite complex, since the motor uses low rotational speed, large torque, the motor needs to be designed quite voluminous, which results in the whole propulsion system being quite expensive and requiring to occupy a large amount of valuable space on the ship; in addition, the propeller mounting shaft needs to penetrate through the ship body, and a special shafting supporting mechanism and a sealing structure need to be designed.

In the traditional annular propulsion system, a motor rotor and a propeller are integrated and are integrally soaked in water, and although the volume of the system is reduced a lot, the lubrication of the relative rotation between the motor stator and the rotor is difficult to realize because the stator and the rotor of the motor are soaked in water; in addition, the motor is soaked, so that the sealing requirement on the whole system is very high, and the stability of the whole system is reduced.

Disclosure of Invention

The utility model aims to provide a novel annular propulsion structure for an electric ship, which overcomes the defects in the prior art.

In order to achieve the purpose, the technical scheme of the utility model is as follows: the utility model provides a novel annular propulsion structure for electric ship, includes driving motor, spiral bevel gear axle, spiral bevel gear ring, base, bearing, spiral bevel gear ring passes through bearing and pedestal connection, spiral bevel gear ring is the loop configuration, and spiral bevel gear ring edge forms the tooth that the annular distributes, and the one end of spiral bevel gear axle and driving motor's output shaft, the other end of spiral bevel gear axle form conical gear, the tooth intermeshing of conical gear tooth and above-mentioned spiral bevel gear ring is equipped with the screw in the spiral bevel gear ring, the screw encircles an organic whole structure with spiral bevel gear.

The utility model discloses a novel annular propulsion structure for an electric ship, which adopts a traditional spiral bevel gear structure, a motor decelerates through the spiral bevel gear structure and then pushes a propeller to rotate, and the motor can adopt a low-torque high-speed motor, so that the motor can be designed to be smaller, and the motor is directly integrated on a steering system; compared with the traditional shaft pushing structure, the annular pushing structure can use a high-rotating-speed and low-torque motor with smaller volume, so that the cost of the motor is reduced; meanwhile, the motor is integrated on the propulsion system, so that the occupied space of the propulsion system can be greatly saved; compared with an integrated annular propulsion mechanism integrating a motor and a propeller, the underwater part of the structure is a traditional mechanical structure, the driving motor is still in a dry environment in the cabin, and the stability of the system is greatly improved.

Detailed Description

The utility model will be further described with reference to the accompanying drawings.

The first embodiment of the utility model discloses a novel annular propulsion structure for an electric ship, which is different from the prior art in that: as shown in fig. 1, the device comprises a driving motor 1, a spiral bevel gear shaft 2, a spiral bevel gear ring 3, a base 4 and a bearing 5, wherein the spiral bevel gear ring 3 is connected with the base 4 through the bearing 5, the spiral bevel gear ring 3 is of an annular structure, teeth distributed in an annular shape are formed on the edge of the spiral bevel gear ring 3, one end of the spiral bevel gear shaft 2 is connected with an output shaft of the driving motor 1, a conical gear 6 is formed at the other end of the spiral bevel gear shaft 2, the teeth of the conical gear 6 are meshed with the teeth of the spiral bevel gear ring 3, a propeller 7 is arranged in the spiral bevel gear ring 3, and the propeller 7 and the spiral bevel gear ring 3 are of an integral structure. The base provides the fixed point for driving motor, provides the bearing support for the curved tooth bevel gear axle, provides worker for the curved tooth screw propeller component and supports and seals.

In the specific implementation, the base 4 is of an annular structure, and an annular assembling portion 8 for assembling the bearing 5 is formed by an inner ring at the edge of the base 4.

When the ship is in specific implementation, the motor is connected and driven through the arc-tooth bevel gear shaft, and the motor is placed inside the ship. The spiral bevel gear connection can promote the moment of torsion of screw end, reduces the rotational speed of screw simultaneously, is showing the efficiency that improves the screw. This allows the use of a higher speed motor that is less costly and more efficient. The whole system is integrated and can be supplied in an integrated assembly mode, as shown in fig. 2-3, the simplified diagram of the system structure is shown, and because the driving mechanical part adopts a traditional mechanical structure, the stability of the system is improved; the driving motor is arranged in the cabin, so that the requirement of the whole system on the sealing part is greatly reduced, and the use stability of the electrical system is improved.

The foregoing is a more detailed description of the present invention in connection with specific preferred embodiments thereof, and it is not intended that the utility model be limited to the specific details set forth herein. For those skilled in the art to which the utility model pertains, several simple deductions or substitutions can be made without departing from the spirit of the utility model, and all shall be considered as belonging to the protection scope of the utility model.
