According to embodiment of the present utility model, there is provided a kind of pitch-controlled system for wind power generating set, the change oar system
System includes pitch variable bearings 17, and its inner ring 171 is fixed relative to the position of wheel hub 11 of wind-driven generator and fixed with reinforcing ring 12,
Outer ring 172 is fixed relative to the leaf position of wind-driven generator.Flange connector 121 is additionally provided with reinforcing ring 12, the connection
Flange 121 can be located on the periphery of reinforcing ring 12.By flange connector 121, pitch drive component 14 is fixed with reinforcing ring 12
Connection, transmission belt pre-tightening apparatus 16 are fixed on the outer ring 172 of pitch variable bearings 17.
So, transmission belt 15 is connected between pitch drive component 14 and transmission belt pre-tightening apparatus 16, specifically, transmission belt
15 can be cog belt, and one end of the cog belt may be coupled to tensioning wheel, driving wheel in pitch drive component 14, the other end
It is connected to transmission belt pre-tightening apparatus 16.
The electrical control cubicles 13 of pitch-controlled system are fixed on the side of reinforcing ring 12, that is, reinforcing ring 12 with the phase of pitch variable bearings 17
To side.Produced when needing to carry out change oar, in pitch drive component 14 and become oar power, become oar power and transmitted through transmission belt 15
To the outer ring 172 of pitch variable bearings 17, so as to drive outer ring 172 to rotate, thus rotary wind power generator group blade, realize becoming
Oar.
Specifically, electrical control cubicles 13 can be fixed in the supporting plate 122 of reinforcing ring 12 by fastening bolt, the supporting plate
122 perpendicular to the axial direction of reinforcing ring 12.So, the size of the supporting plate 122 of reinforcing ring 12 can not be too small, to ensure its own
Intensity and with the bonding strength between electrical control cubicles 13.In addition, electrical control cubicles 13 or miscellaneous part are connected for convenience, can be further
Erection joint is formed in supporting plate 122.
The inner ring 171 of pitch variable bearings 17 can be fixed on the opposite side of reinforcing ring 12, as shown in figure 4, can pass through between the two

Three groups of above-mentioned pitch-controlled systems, are respectively used to carry out change oar to three groups of blades.The structure of this three groups of pitch-controlled systems is identical, but but that
This is independently controlled.
Below, the assembling process of above-mentioned pitch-controlled system is specifically described.
First, the inner ring 171 of pitch variable bearings 17 and reinforcing ring 12 are assembled together, for example, using bolts assemblies.Then
The grade part of electrical control cubicles 13 is directly installed in the supporting plate 122 of reinforcing ring 12, then transmission belt pre-tightening apparatus 16 are fixed on change
On the outer ring 172 of oar bearing 17, pitch drive component 14 is arranged on the flange connector 121 of reinforcing ring 12.Afterwards will transmission
Band 15 is stretched between transmission belt pre-tightening apparatus 16 and pitch drive component 14.The assemble sequence of certain the above part can be with
Any adjustment, is not only restricted to above-mentioned time sequencing.
So, pitch variable bearings 17, reinforcing ring 12, electrical control cubicles 13, transmission belt pre-tightening apparatus 16, pitch drive component 14 and biography
It is dynamic to complete pre-assembled in the outside of wheel hub 11 with 15, including original part for needing the assembling in wheel hub 11 also can be in wheel hub
11 outsides complete assembling, and the module after now assembling can turn into assembling module, as shown in Figure 5.Afterwards, just can be by the assembling mould
Block is integrally assembled on wheel hub 11.Specifically, the inner ring 171, reinforcing ring of pitch variable bearings 17 is sequentially passed through using fastening bolt
12 and wheel hub 11 come complete assembling, as shown in Figure 6.
In addition, for three groups of pitch-controlled systems on wind-driven generator, can simultaneously carry out assemble flow.For example, can be same
, then be assembled to assembling module on wheel hub 11 together by die-filling piece of fashionable dress combo, and this can significantly improve efficiency of assembling.
In pitch-controlled system provided by the utility model, for connecting the flange connector of pitch drive component 14 from original
It is arranged on to be changed on wheel hub 11 and is arranged on reinforcing ring 12, and eliminates the web knot on the wheel hub 11 of wind-driven generator
Structure, therefore, such wheel hub can be the wheel hub structure such as Fig. 3 institutes according to embodiment of the present utility model without web-type wheel hub
Show.So when being assembled, hindered there is no web, directly assembling module can be installed on wheel hub 11, without such as
Original assembling for carrying out some parts in wheel hub 11 like that, is no longer limited by narrow space in wheel hub 11, so as to optimize
The assembly technology of pitch-controlled system.Equally, when needing to safeguard inner part, easily pitch-controlled system can be dismantled down
Come, so as to upkeep operation can be carried out easily outside wheel hub.
In addition, the size of reinforcing ring 12 is increased, so as to overall construction intensity can be improved.The structure of wheel hub is able to simultaneously
Simplify, and increase the inner space of wheel hub 11, and then can significantly simplify its manufacturing process and reduce manufacturing cost.
According to another embodiment of the present utility model, a kind of wind-driven generator should be provided, the wind-driven generator includes upper
Pitch-controlled system and wheel hub 11 are stated, be will not be repeated here.
Specific embodiment of the present utility model is described in detail above, although show and described some realities
Example is applied, it will be understood by those skilled in the art that not departing from this practicality that its scope is limited by claim and its equivalent
In the case of new principle and spirit, these embodiments can be modified and perfect, these modifications and improve also should be
In protection domain of the present utility model.
