Abstract
The utility model is related to the clip location structure of a kind of wheel hub and blade root, wheel hub includes upper supporting plate, lower carrier plate, front band, lower catch hoop and bolt assembly；Upper supporting plate is pressed on front band, and lower carrier plate is pressed on lower catch hoop；It is provided with bolt hole on upper supporting plate, lower carrier plate, front band, lower catch hoop, upper supporting plate, front band, lower catch hoop and lower carrier plate are sequentially connected by bolt assembly and are fixed as one；The edge of the upper supporting plate and lower carrier plate, which is equipped with, to be turned over time, and the front band and lower catch hoop is provided with arc groove, and blade root is clamped up and down in the arc groove of front band and lower catch hoop so that blade root is limited in the arc groove of upper and lower clip；Front band is turned over by upper supporting plate all over limit, and lower catch hoop is turned over by lower carrier plate all over limit.The utility model prevents clip and blade after bolt looseness from flying out, simple in structure, easy processing location structure using annular groove form positioning lathe dog on wheel hub support plate.
Description
Technical field：
The present invention relates to fan blades, and field is fixedly mounted, and in particular to a kind of clip location structure of wheel hub and blade root.
Background technology：
With the development of national economy, all trades and professions have been goed deep into the use of wind turbine, and the major impetus component of wind turbine is wheel
Hub and blade.General rotation speed of fan uses step finger setting clip, clip is fixed with bolt in 100-300rpm, wheel hub support plate
On support plate, and 2-3 times that this secondary design hub rotation speed is former wind turbine, support plate use annular groove form positioning lathe dog, moreover it is possible to prevent
Clip and blade fly out after bolt looseness.
Invention content：
The purpose of invention：A kind of blade root fixed structure with limit function is provided, while enhancing the anti-shearing energy of bolt
Power.
Technical solution：
The present invention is a kind of clip location structure of wheel hub and blade root,
Wheel hub includes upper supporting plate, lower carrier plate, front band, lower catch hoop and bolt assembly；
Upper supporting plate is pressed on front band, and lower carrier plate is pressed on lower catch hoop；
It is provided with bolt hole on upper supporting plate, lower carrier plate, front band, lower catch hoop, by bolt assembly by upper supporting plate, upper card
Hoop, lower catch hoop and lower carrier plate are sequentially connected and are fixed as one；
The edge of the upper supporting plate and lower carrier plate, which is equipped with, to be turned over time, and the front band and lower catch hoop is provided with arc groove,
Blade root is clamped up and down in the arc groove of front band and lower catch hoop so that blade root is limited in the arc groove of upper and lower clip；
Front band is turned over by upper supporting plate all over limit, and lower catch hoop is turned over by lower carrier plate all over limit.
Further, the edge of the upper supporting plate and lower carrier plate be arc-shaped edges, it is described turn over all over be circular arc flange.Further
, the face that upper lower catch hoop corresponds to upper lower carrier plate flange is arc surface.
Further, blade root is equipped with flange, and flange is limited by upper lower catch hoop.
Further, bolt hole is multiple, and relative to the symmetrical distribution of blade root.
Technique effect：
Using annular groove form positioning lathe dog on wheel hub support plate, prevents clip and blade after bolt looseness from flying out, be a kind of knot
Structure is simple, easy processing location structure.
Description of the drawings：
Fig. 1 wheel hub sectional views；
Fig. 2 wheel hubs topography；
Wherein：1-lower carrier plate, 2-lower catch hoops, 3-blade roots, 4-front bands, 5-upper supporting plates, 6-bolt assemblies.
Specific implementation mode：
A kind of wheel hub clip location structure is described in further detail below in conjunction with attached drawing：
The present invention is a kind of clip location structure of wheel hub and blade root,
Wheel hub includes upper supporting plate, lower carrier plate, front band, lower catch hoop and bolt assembly；
Upper supporting plate is pressed on front band, and lower carrier plate is pressed on lower catch hoop；
It is provided with bolt hole on upper supporting plate, lower carrier plate, front band, lower catch hoop, by bolt assembly by upper supporting plate, upper card
Hoop, lower catch hoop and lower carrier plate are sequentially connected and are fixed as one；
The edge of the upper supporting plate and lower carrier plate, which is equipped with, to be turned over time, and the front band and lower catch hoop is provided with arc groove,
Blade root is clamped up and down in the arc groove of front band and lower catch hoop so that blade root is limited in the arc groove of upper and lower clip；
Front band is turned over by upper supporting plate all over limit, and lower catch hoop is turned over by lower carrier plate all over limit；
The edge of the upper supporting plate and lower carrier plate be arc-shaped edges, it is described turn over all over be circular arc flange.Further, block up and down
The face of the corresponding upper lower carrier plate flange of hoop is arc surface；
Blade root is equipped with flange, and flange is limited by upper lower catch hoop；
Bolt hole is multiple, and relative to the symmetrical distribution of blade root.
