Second blade rack the 13, second nut 14.
The electromotor entirety of this practicality is divided into blade, support section and gear portion in two sub-sections, its Leaf
And support section is responsible for accepting wind energy by blade, and wind energy is delivered to slow-speed shaft by blade rack.Variable speed generation part
It is responsible for by gear, the torque on slow-speed shaft is delivered to motor, completes generating.
Blade respectively concrete structure as it is shown in figure 1, the vertical setting of blade 12, totally 5, and in equidistant ring array distribution in
On cylinder with slow-speed shaft 5 as axle center, forming the design of five blade wind wheel, blade 12 uses lift-type blade 12, utilizes blade
12 both sides flow velocity differences obtain lift, promote wheel rotation by lift.Blade 12 is made up of aluminium alloy, and takes the knot of hollow out
Structure.In the present embodiment, blade 12 selection standard aerofoil profile NACA63-412.It it is a Low Speed Airfoil system setting up the earliest of American NACA
Row.Compared with other aerofoil profiles in early days, there are higher maximum lift coefficient and relatively low resistance coefficient.The aerofoil profile that we are selected
It is under the jurisdiction of the six bit digital aerofoil profiles of NACA, is characterized in the range of certain lift coefficient having lower resistance characteristic, non-design
Under the conditions of also have satisfied result.This aerofoil profile has the high lift coefficient of comparison and the highest critical Mach number.
Support section structure is as follows: for ensureing stability, at two trisection points of every blade 12, use level respectively
Blade rack be attached fixing with slow-speed shaft 5, respectively the first blade rack 11 and the second blade rack 13 in figure.Leaf
Connected mode between sheet 12 and blade rack is detachable gripping, and concrete fixed form is: in blade 12 trisection
The location that two rivets grip, and the vertical direction suffered by balance blade 12 it is respectively mounted for blade 12 at Dian
Gravity.Blade 12 is installed with on slow-speed shaft 5 by blade rack, and the first blade rack 11 and the second blade rack 13 pass through respectively
Nut the 10, second nut 14 is fixed on slow-speed shaft 5, and blade rack part is responsible for being supported blade 12 and being subject to by blade 12
To torque be delivered to axle.Support bracket fastened slow-speed shaft 5 is provided with and mills the axle that two faceted cylinders are externally threaded.
As in figure 2 it is shown, have the axis hole of correspondingly-shaped accordingly at the first blade rack 11 and the second blade rack 13, in order to by blade
The moment that support receives is delivered on axle.Prevent the instability that the vertical tremor of support causes, nut and the outer spiral shell on slow-speed shaft 5
Stricture of vagina uses screw pair to connect.
Gear part is delivered to motor 1 after being responsible for accelerating the rotation of slow-speed shaft 5, and its main part is in casing
Gear train.Casing detachably in lower box 7 and upper box 9 assemble.In gear train, low-speed gear 8 and high gear 2 are by key
Connect and be separately fixed on slow-speed shaft 5 and high speed shaft 4.Slow-speed shaft 5 and high speed shaft 4 are by first angular contact bearing the 3, second angular contact
Bearing 6 is fixed on lower box 7, upper box 9.
Gear train part is responsible for the high rotating speed that slow-speed of revolution transition is motor 1 from blade 12, has reached high power, has steadily sent out
The effect of electricity.Gear train is made up of high gear 2 and low-speed gear 8 double reduction, and wherein low-speed gear 8 modulus is 0.8, the number of teeth
It is 71, is fixed on slow-speed shaft 5 by bonded.High gear 2 is double-layer gear, its at the middle and upper levels the number of teeth be 15, modulus is
0.8, lower floor's number of teeth is 59, and modulus is 0.6, is fixed on high speed shaft 4.
Two-stage gear is worked in coordination, and defines the speed-up ratio of 1:39, allows 12 groups of blade can drive electricity by high gear 2
Machine 1 reaches the generating rotating speed that it is specified, enables the design to use the slowspeed machine of relatively inexpensive high-speed electric expreess locomotive 1 replacement costliness
1 generates electricity.
The installation procedure of this utility unit as it is shown on figure 3, particularly as follows:
1. in carrying, the first blade rack 11 and the second blade rack 13, blade 12 separated with main part with
Save space；
The most in use, user needs first to be set on slow-speed shaft 5 by support 11, aligns with slow-speed shaft 5 shape, installs first
Nut 10.
3. installing 5 pieces of blades 12, blade is by the hole being inserted on support correspondence, owing to rivet portion contour line is more than hole
Profile, blade 12 tentatively will be supported on the first blade rack 11 by rivet
4. installing the second blade rack 13, centre bore aligns with slow-speed shaft 5 shape, simultaneously because the first blade rack 11 exists
Having opening at corresponding 5 blades, support will be pushed onto on 5 blades, also due to rivet portion contour line is more than opening portion
Contour line, the first blade rack 11 is supported by blade 12, and blade 12 is completely restricted in fixed position simultaneously, installs the second spiral shell
Female 14, installation.
Operational process is as follows:
1. blow air over blade 12, provide torque for blade 12；
2. blade transmits torque to the first blade rack 11 and the second blade rack 13；
3. the first blade rack 11 and the second blade rack 13 transmit torque on slow-speed shaft 5；
4. slow-speed shaft 5 will drive low-speed gear 8；
5. low-speed gear 8 drives high gear 2；
6. high gear 2 drive motor 1, completes the flow process that generates electricity.
Dismounting flow process is as follows:
1. unload the second nut 14；
2. take off the first blade rack 11 and blade 12；
3. unload the first nut 10；
4. take off the second blade rack 13；
The most now having dismantled, small-sized fan can be carried in the case of taking very small volume.
Embodiment described above is the one preferably scheme of this practicality, so itself and be not used to limit this practicality.Have
Close the those of ordinary skill of technical field, in the case of without departing from the spirit and scope of this practicality, it is also possible to make various change
Change and modification.The technical scheme that the most all modes taking equivalent or equivalent transformation are obtained, all falls within the guarantor of this practicality
In the range of protecting.
