Description
Technical field
The utility model belongs to large-scale wind driven generator field, more particularly to a kind of blades of large-scale wind driven generator and wheel hub
Attachment structure.
Background technology
With the maximization of wind-driven generator and the development of low speed wind power wind turbine, matched fiberglass blade is got over
It is increasingly heavier, it is desirable to which that the moment of flexure and active force that blade root can bear are increasing, between blade and wheel hub more to grow
Stable connection requirement also more and more higher, because the volume of blade and wheel hub is larger, the two is by way of bolt
Be fixedly connected, connecting portion it is uniform large number of bolt hole, in abutting joint, it is difficult to which each bolt hole is corresponded
On, thus to connection work bring great inconvenience, such that operating efficiency is low, labor strength is big, time-consuming etc. asks for installation
Topic.
Utility model content
The utility model is for deficiency present in background technology, and a kind of blades of large-scale wind driven generator provided is with taking turns
Hub attachment structure.
A kind of blades of large-scale wind driven generator of the present utility model and wheel hub attachment structure, including blade and wheel hub, its institute
The front end for the wheel hub stated is that circular arc, tail end are provided with rotor shaft, uniform three groups of blade connecting portions, blade company on the circumference of wheel hub
Socket part is uniform screwed hole, the internal installation jack for being provided with more than one group in circular, its circumference；The root of described blade is set
There are the wheel hub connecting portion being connected with blade connecting portion, uniform a screw hole in its circumference, inside is provided with groove, set in groove
There is the installation inserted block being used cooperatively with installation jack, described groove is built-in with pad, pad is provided with installation inserted block and passes through hole.
Preferably installation jack inside blade connecting portion is three groups as of the present utility model, is respectively circular, ellipse
And triangle；Installation inserted block in groove is three groups, is respectively circular, ellipse and triangle, installs jack and installation inserted block
Correspond.
Thickness as of the present utility model preferred, described pad is not less than the height of groove, and the thickness of pad is little
In the length of installation inserted block.
A kind of blades of large-scale wind driven generator of the present utility model and wheel hub attachment structure, simple in construction, reasonable in design, peace
Fill it is easy to operate, quickly each bolt hole can be corresponded, labor strength and work greatly reduces
Time, raise labour efficiency.There is stability and intensity between increase blade and wheel hub additionally, due to plug division is added
Effect.
Brief description of the drawings
Fig. 1 is the front view of overall structure diagram of the present utility model；
Fig. 2 is root of blade structural representation of the present utility model.
Embodiment
Below in conjunction with the accompanying drawings 1 and accompanying drawing 2 knot is connected with wheel hub to a kind of blades of large-scale wind driven generator of the present utility model
Structure, it is described further.
Embodiment 1
A kind of blades of large-scale wind driven generator of the present utility model and wheel hub attachment structure, including blade 1 and wheel hub 2, its
The front end of described wheel hub 2 is that circular arc, tail end are provided with rotor shaft 3, on the circumference of wheel hub 2 uniformly three groups of blade connecting portions 4,
