Description
Technical field
The present invention relates to a kind of traction motor for ship, this traction electric machine is mainly used in and often is in the higher occasion of navigation environment environmental demands or the boats and ships of other specific occasions.
Background technology
The engine of boats and ships normally adopts combustion engine, but there is the possibility to water pollution in combustion engine, and fuel oil and lubricating oil all may leak, and the waste gas of discharge also can influence the air quality of cabin.Near some specific occasions such as water head site, the waters that has higher requirements of environmental pollution such as scenic spot, forbid that boats and ships use combustion engine as major impetus.Simultaneously, the power of combustion engine will pass through power-transfer clutch, change speed gear box, transmission shaft, and through driving screw propeller after twice commutation, mechanical efficiency is lower again.
Its cabin space of the boats and ships that navigate by water in this waters is narrow and small, therefore requires power of traction motor density height, little, the good heat dissipation of volume.The traction electric machine of existing ship adopts natural ventilation and induced ventilation to cool off mostly, and cooling performance is limited; And when shipping high speed moved, coolant air produced very big friction loss to motor.
Boats and ships adopt single engine mostly at present, in case et out of order, boats and ships just run out of steam, and may the safety of navigation of boats and ships be worked the mischief.
Summary of the invention
The technical problem to be solved in the present invention is: a kind of have good good cooling results, efficient height, pollution-free are provided, and the traction motor for ship that can on the hybrid power boats and ships, use, this motor is mainly used in the boats and ships of frequent navigation at the specific bodies of water, for boats and ships provide power.
The technical solution adopted in the present invention is: a kind of traction motor for ship, be mainly used in the boats and ships of frequent navigation at the specific bodies of water, for boats and ships provide power, it has the DC machine body, DC machine is provided with outlet and inlet vent window and corresponding blowing engine, this motor has twin shaft and stretches structure, and wherein the power output shaft end is connected with the screw propeller of boats and ships, and the horsepower input axle head is connected with the power take-off shaft of marine internal combustion engine by power-transfer clutch and change speed gear box; In the stator casing of DC machine, be provided with into, the Coolant gallery of discharge port, in DC machine, be provided with the temperature sensor that links to each other with cooling water pump.
The stator casing of described DC machine is made of the double-level-metal plate, forms jacket structuredly, is provided with the labyrinth type water channel that is divided into by floor in the double layer of metal plate.
But DC machine adopt have good rise deceleration and stopping performance, stepless speed control on a large scale, overload capacity is strong, reliability is high DC machine.This motor has two cover cooling systems, and (normally not too high in ambient temperature, when boats and ships navigate by water with cruising speed) only starts blowing engine and carry out forced-draught cooling when running temperature does not exceed setting value; When the temperature sensor in being located at motor detects running temperature and exceeds setting value (when normally shipping high speed operation or ambient temperature are higher), excite cooling water pump to start, fresh water in river course or the lake is pumped in the Coolant gallery of motor stator shell, cooling water expansion tank is when the sluice, with taking away most of heat that motor stator produces, enter river course or lake by discharge port again.
This motor is that twin shaft is stretched structure, and wherein the power output shaft end is connected with the screw propeller of boats and ships, and the horsepower input axle head is connected with the power take-off shaft of marine internal combustion engine by power-transfer clutch and change speed gear box.Because of unexpected situation occurring and can't move or boats and ships needs at a high speed under the situation of navigation, the standby combustion engine that can start boats and ships is emergent, obtains enough power to guarantee boats and ships at motor.
The invention has the beneficial effects as follows: this traction motor for ship is mainly used in the boats and ships of frequent navigation at the specific bodies of water, for boats and ships provide power.This motor possesses air-cooled and water-cooled two cover cooling systems, and the cooling performance of motor improves, thereby the power density of motor is improved, and motor volume also can correspondingly reduce.This motor has twin shaft and stretches structure, and motor can be connected with the power take-off shaft of combustion engine under special status, realizes that the hybrid power of boats and ships drives.

The specific embodiment
A kind of traction motor for ship, be mainly used in the boats and ships of frequent navigation at the specific bodies of water, for boats and ships provide power, as shown in Figure 1, it has DC machine 1 body, and DC machine 1 is provided with outlet and inlet vent window and corresponding blowing engine 2, has twin shaft and stretches structure, wherein the power output shaft end is connected with the screw propeller of boats and ships, and the horsepower input axle head is connected with the power take-off shaft of marine internal combustion engine by power-transfer clutch and change speed gear box; In the stator casing of DC machine 1, be provided with into, the Coolant gallery of discharge port, in DC machine 1, be provided with the temperature sensor that links to each other with cooling water pump.
The stator casing of DC machine 1 is made of the double-level-metal plate, forms jacket structuredly, is provided with the labyrinth type water channel that is divided into by floor in the double layer of metal plate.
But DC machine adopt have good rise deceleration and stopping performance, stepless speed control on a large scale, overload capacity is strong, reliability is high DC machine.This motor has two cover cooling systems, and (normally not too high in ambient temperature, when boats and ships navigate by water with cruising speed) only starts blowing engine and carry out forced-draught cooling when running temperature does not exceed setting value; When the temperature sensor in being located at motor detects running temperature and exceeds setting value (when normally shipping high speed operation or ambient temperature are higher), excite cooling water pump to start, fresh water in river course or the lake is pumped in the Coolant gallery of motor stator shell, cooling water expansion tank is when the sluice, with taking away most of heat that motor stator produces, enter river course or lake by discharge port again.
This DC machine is that twin shaft is stretched structure, and wherein the power output shaft end is connected with the screw propeller of boats and ships, and the horsepower input axle head is connected with the power take-off shaft of marine internal combustion engine by power-transfer clutch and change speed gear box.Because of unexpected situation occurring and can't move or boats and ships needs at a high speed under the situation of navigation, the standby combustion engine that can start boats and ships is emergent, obtains enough power to guarantee boats and ships at motor.
The power supply of DC machine can adopt secondary batterys such as hydrogen power fuel battery, nickel-cadmium cell, lead-acid battery, Ni-MH battery, lithium ion battery.
