Abstract
The utility model relates to a ship propeller, which comprises a propeller, a motor and an operating handle for controlling the rotating speed of the motor. The ship propeller is characterized in that the propeller is driven by the output shaft of the motor to rotate through a retarding mechanism. Compared with the prior art, a retarding mechanism is arranged between the output shaft of the motor and the propeller. When a ship needs to be maintained in a low-speed running state, the rotating speed of the motor is controlled by the operating handle and the rotating speed of the propeller is effectively and further reduced through the retarding mechanism. Therefore, the ship can be stably maintained at a low-speed running state.
Description
Technical field
The utility model relates to a kind of marine installation, specifically is a kind of marine propeller.
Background technology
Early stage marine propeller mostly is that power drives screw propeller and pushes away with the gasoline engine; This propelling unit consumption oil is big; CO2 emissions are big, and cause tail gas pollution easily, and propelling unit can produce bigger noise in the boats and ships traveling process; When being assemblied on the small-sized pleasure-boat especially, tail gas that this marine propeller brings and noise emission can bring bigger human discomfort to the visitor.To this deficiency; People had invented a kind of follow-on marine propeller afterwards, and it is installed in the underwater with exhaust gear, though this marine propeller is not with the tail gas exhaust to atmosphere; And reduced the noise that gas emission device produces effectively; But a large amount of tail gas enters in the water, has seriously influenced water quality, causes marine pollution.Current; Along with people's environmental consciousness ground strengthens, and it is the energy that the marine propeller that is assemblied in spitkit at present all adopts with the storage battery basically, drives screw propeller traction boats and ships through DC motor; Than gasoline engine; Electrical motor can not produce tail gas pollution, and because electrical motor is embedded under the water surface, the noise jamming that electrical motor produces is also less.But existing this marine propeller all is directly connected to the output shaft of electrical motor on the screw propeller, is difficult to control boats and ships and keeps low speed to move ahead.And for common small-sized pleasure-boat, the visitor often needs pleasure-boat slowly to move ahead to enjoy the scenery, and therefore, remains this marine propeller is carried out certain improvement, to satisfy the requirement that marine low speed is moved ahead.
The utility model content
The utility model technical matters to be solved is to provide a kind of inside that the marine propeller of speed reduction gearing is housed to above-mentioned prior art.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this marine propeller comprises screw propeller, motor and can control the operating handle of motor speed that it is characterized in that: said motor drives described screw propeller rotation through a speed reduction gearing.
Preferably; Described operating handle is fixed on the controller; Described controller is connected the upper end of a pipe link, and the lower end of pipe link is equipped with a housing, and described speed reduction gearing is located at the inside of this housing; Said motor is connected an end of housing, and affiliated screw propeller is connected the other end of this housing.Through rotating operating handle, can change rotating speed of motor, and then regulate the fltting speed of boats and ships.
Further preferred, the tail end of described operating handle is provided with the button that a said motor of control rotates forward or backwards.Press this button, can control moving ahead or falling back of boats and ships.Certainly, can also button be arranged on the controller, as long as handled easily.
Further preferred, described pipe link is provided with mounting bracket.Can also be as required the setting height(from bottom) of mounting bracket being designed to can up-down adjustment, to adapt to the installation requirements of different boats and ships.Through this mounting bracket, marine propeller can be fixedly mounted on the hull, and is higher to the propulsion coefficient of boats and ships.
Compared with prior art; The utility model also is provided with speed reduction gearing between motor and screw propeller; When wanting to make boats and ships to keep lower-speed state; Except through the operating handle control motor speed, can also combine this speed reduction gearing to come further effectively to reduce the rotating speed of screw propeller, thereby make boats and ships more stably remain on the low speed forward traveling.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the three-dimensional exploded view of Fig. 1.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2; The operating handle 1 of this marine propeller is fixedly mounted on the controller 2; The storage battery (not shown) is installed in controller 2 inside, and controller 2 is installed in the upper end of pipe link 4, is connected on the motor 5 after the electric wire in the controller 2 passes from pipe link 4 inside.The lower end of pipe link 4 is equipped with a housing 8, and the front end of motor 5 is installed in an end of housing 8, and the rear end of motor 5 is equipped with electric motor end cap 51; Screw propeller 6 is installed in the other end of housing 8; The speed reduction gearing 7 that connects motor 5 and screw propeller 6 is installed in the inside of housing 8, and in the present embodiment, what speed reduction gearing 7 adopted is gear reduction; Has compact conformation, the little and precision advantage of higher in backhaul gap.In addition, be that anti-sealing gets into housing 8 inside, near the end of screw propeller 6 one sides housing end plug 81 be installed at housing 8.
For this marine propeller is fixed on the hull, on pipe link 4, be provided with the mounting bracket 3 that setting height(from bottom) can be regulated, during installation; Mounting bracket 3 generally is fixed on the ship side; Like this, marine propeller is difficult in the process of navigating, shaking, and is higher to the propulsion coefficient of boats and ships.
When desire changes the boats and ships gait of march, can change the rotating speed of motor 5 by rotating operating handle 1, and then change the rotating speed of screw propeller 6.When desiring to make boats and ships to move ahead or fall back, press the button 9 that is positioned at operating handle 1 tail end and make motor 5 be in the forward or reverse state to get final product.And the speed reduction gearing 7 of the utility model through between motor 5 and screw propeller 6, setting up; Can also further reduce the rotating speed of screw propeller 6; When especially boats and ships need remain on the low speed forward traveling for a long time, speed reduction gearing 7 compounding practice handles 1 used better effects if.
The utility model can have various deformation not only for above-mentioned embodiment in this specification sheets scope of disclosure.All technical schemes that adopt the replacement of equivalent technologies means to realize all are regarded as in the protection domain of the utility model.
