Description
Technical field
The invention belongs to low wind speed wind power generation fields, and in particular to a kind of low wind speed wind turbine gearbox drive mechanism.
Background technology
Wind energy has as regenerative resource is distributed wide, low density characteristic, and extremely suitable exploitation nearby, online makes nearby
With.In China, available low wind speed resource area accounts for about the 68% of national wind energy resources area, and close to network load by
End area, is the Main way of current China's Wind Power Generation.But low wind speed wind power generation domain variability becomes without similar in recent years
The radical innovation of fast variable pitch technology is broken through so that low wind speed wind-powered electricity generation utilization ratio does not obtain big promotion.The low wind speed
Refer in 5 meter per seconds wind speed below, under low wind speed condition, fan blade can not drive existing wind turbine gearbox to run.
Invention content
The technical problems to be solved by the invention are just to provide a kind of low wind speed offset-type wind turbine gearbox drive mechanism, it
Wind turbine can be made to be run under the wind regime for cutting wind speed less than wind turbine.
It is realized the technical problem to be solved by the present invention is to technical solution in this way, it includes that blade, planet subtract
Fast grade, the first stage parallel speed increasing and the second stage parallel speed increasing, planetary reduction gear grade have planet carrier, ring gear, planetary gear and sun gear,
Further include motor, electric motor speed reducer gear and blade shaft gear, blade is mounted in blade shaft gear front end, sharf and planet carrier phase
Even, motor connects electric motor speed reducer gear, and electric motor speed reducer gear is engaged with blade shaft gear, sun gear and the first stage parallel speed increasing master
Moving teeth is coaxially connected, and the first stage parallel speed increasing driven tooth is coaxially connected with the second stage parallel speed increasing driving tooth, the second parallel speed increasing
The shaft of grade driven shaft is output shaft.
Since motor is connected with electric motor speed reducer gear, electric motor speed reducer gear is engaged with blade shaft gear, sharf and row
Carrier is connected, and by the deceleration of electric motor speed reducer gear, improves the torque of motor, and torque is transmitted to sharf.
The solution have the advantages that：
When wind speed is not achieved, and wind turbine is made to cut wind speed, compensation torque is provided by motor, main axis, wind turbine is made to start to transport
Row；When wind speed is enough, motor power-off, idle running do not export rotating speed and torque.Blade rotating speed adds two by primary planet grade
Generator is output to after grade parallel stage speed increasing mechanism speedup to generate electricity.Wind-driven generator can be made to be cut less than wind turbine in wind speed
It is run under the wind regime of wind speed, increases the generated energy and generating efficiency of wind turbine, extend wind turbine in the operation in low wind speed region
Between.
Description of the drawings
The description of the drawings of the present invention is as follows：
Fig. 1 is the transmission schematic diagram of the present invention；
Fig. 2 is the structural schematic diagram of the present invention.
Specific implementation mode
The invention will be further described with reference to the accompanying drawings and examples：
As depicted in figs. 1 and 2, including blade 1, planetary reduction gear grade, the first stage parallel speed increasing and the second stage parallel speed increasing, planet subtract
Fast grade has planet carrier 10, ring gear 4, planetary gear 11 and sun gear 9, it is characterized in that：Further include motor 2,3 and of electric motor speed reducer gear
Blade shaft gear 12, blade 1 are mounted in 12 front end of blade shaft gear, and sharf is connected with planet carrier 10, and motor 2 connects decelerating through motor
Gear 3, electric motor speed reducer gear 3 are engaged with blade shaft gear 12, sun gear 9 with the first stage parallel speed increasing driving tooth 8 is coaxial is connected,
First stage parallel speed increasing driven tooth 5 with the second stage parallel speed increasing driving tooth 7 is coaxial is connected, the second stage parallel speed increasing driven shaft 6
Shaft is output shaft.
Motor 2 and electric motor speed reducer gear 3 are distributed with 3 in even circumferential, and planetary gear 11 is distributed with 5 in even circumferential.
The wind turbine gearbox is the land low wind speed gear case of blower of 2MW, includes input stage torque mechanism（Motor）、
Primary planet grade and two-stage parallel stage wind power gear speedup structure.It is low velocity wind that it, which is inputted, and wind is unstable.The present invention is in gear
Case front end adds a torque mechanism, is made of motor 2, electric motor speed reducer gear 3 and blade shaft gear 12, and effect is to work as wind speed
Be not achieved make wind turbine cut wind speed when, by motor provide compensation torque, make main axis；When wind speed is enough, motor power-off,
Idle running, does not export rotating speed and torque.The speed of mainshaft exports after adding two-stage parallel stage speed increasing mechanism speedup by primary planet grade
It generates electricity to generator.
Compared with the low wind speed gear case of blower of traditional 2MW, the present invention can be such that wind-driven generator is cut less than wind turbine in wind speed
Enter and run under the wind regime of wind speed, increase the generated energy and generating efficiency of wind turbine, extends operation of the wind turbine in low wind speed region
Time.
