Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] like figure 1 As shown, a ship stern thruster arrangement structure includes a drive motor 2 and a stern thruster body 1. The stern thruster body 1 is installed below the propulsion shafting, and the installation position of the drive motor 2 is higher than the shaft generator 10. The drive shaft 3 extending downward is connected to the output end of the motor 2. The drive shaft 3 will not occupy too much space, and will not interfere with or occupy the installation space of the shaft generator 10, coupling 8, propulsion shaft 9 and other equipment. , the lower end of the drive shaft 3 is in transmission connection with the tail side pusher body 1, and the drive motor 2 and the drive shaft 3 are coaxially arranged vertically. Adopting the above arrangement avoids the tail shaft area with narrow space and many equipments, and avoids the ...

Abstract

The invention discloses a ship tail side thrust arrangement structure which comprises a drive motor and a tail side thrust body, the installation position of the drive motor is higher than that of a shaft generator, the output end of the drive motor is in transmission connection with a drive shaft extending downwards, and the lower end of the drive shaft is in transmission connection with the tailside thrust body. The split type design and supply are adopted between the tail side pushing body and the driving motor, the tail side pushing body and the driving motor are installed in a separatedmode and connected through the driving shaft, a tail shaft area with narrow space and numerous devices is avoided, conflict between the tail side pushing body and other devices is avoided, and optimalarrangement of the devices in the tail shaft area is facilitated.

Description

technical field [0001] The invention relates to the technical field of ships, in particular, it relates to a ship stern thrust arrangement structure. Background technique [0002] Line container ships, multi-purpose ships and other ship types that require high maneuverability for entering and leaving ports often need to be equipped with stern thrusters at the tail. However, this type of ship has a low square coefficient, and the stern line of the hull is thin, and the space is very tight. In order to obtain better turning moment under different draft conditions, the stern thruster is usually arranged as close as possible to the stern and the bottom of the ship, this area is the stern shaft area of ​​the ship. How to arrange the tail thruster in the narrow tail shaft space is a difficult problem in the design of this type of ship. [0003] The arrangement of the stern thruster in the prior art is as follows: the stern thruster body and the drive motor are integrally supplie...
