Description
Technical field
This utility model is that a kind of direct bonding region thickness-adjusting layer of blade of wind-driven generator trailing edge spreads structure, belongs to wind
Power generator vane manufacturing field.
Background technology
Fan blade is one of component of Wind turbines most critical, with current fan blade it is increasingly longer, to its quality
The requirement of reliability also more and more higher.Fan blade is used as a kind of composite, with stronger architectural characteristic, its mechanical property
And damage rule depends not only on each component material property, while also depending on microscopical structure feature.Blade is generally main
By suction surface（SS）Housing, pressure face（PS）Housing and web elements are constituted, and SS faces, PS faces and web are by bonding agent and splicing tape
Bonding is formed.The adhesion zone of blade is link most weak in overall structure.In the prior art, fan blade product trailing edge is straight
Connect adhesion zone thickness and the overproof situation of thickness easily occur, and it is well known that bonding agent thickness is thicker, its defect for including is got over
Many, the impact of intensity and service life to fan blade is bigger.Therefore, solve the direct bonding region thickness of trailing edge to surpass
Difference problem is significant.
The content of the invention
Technical problem to be solved in the utility model is the shortcoming and deficiency for prior art, proposes that a kind of design is closed
The direct bonding region thickness-adjusting layer of reason, trailing edge simple to operate spreads structure.
Technical problem to be solved in the utility model is realized by following technical scheme.This utility model is
A kind of direct bonding region thickness-adjusting layer of fan blade trailing edge spreads structure, is characterized in：In the direct adhesive thickness of trailing edge
There is overproof region, if each pre-buried dried layer glass-fiber-fabric in PS faces, SS faces in the region, glass-fiber-fabric is laid in PS faces, SS faces
The lower surface of cortex, the upper surface of unidirectional layer of cloth in Inner Mongol, keep the gentle transition at edge during laying, if it is pre- in advance to form dried layer
The adjustment structure sheaf of the glass-fiber-fabric laying buried, adjustment structure sheaf by way of priming by vacuum it is overall with housing laying into
Type.
The direct bonding region thickness-adjusting layer of fan blade trailing edge described in the utility model spreads structure, and its is further preferred
Technical scheme be：The glass-fiber-fabric of described adjustment structure sheaf laying is biaxially glass-fiber-fabric or three axial glass-fiber-fabrics, laying side
To being carried out from blade root to blade tip.
The direct bonding region thickness-adjusting layer of fan blade trailing edge described in the utility model spreads structure, and its is further preferred
Technical scheme be：The glass-fiber-fabric of described adjustment structure sheaf laying is using starting point is identical, the successively interior wrong laying structure of terminal.
The direct bonding region thickness-adjusting layer of fan blade trailing edge described in the utility model spreads structure, and its is further preferred
Technical scheme be：The PS faces glass-fiber-fabric of described adjustment structure sheaf laying is tangential need to fill the laying of trailing edge groove, against trailing edge
Typing line projection, glass-fiber-fabric tangential lay in SS faces is away from trailing edge parting line 3-8mm.
This utility model structure is adjusted to the direct bonding region thickness of fan blade trailing edge, reduces trailing edge and directly glues
Area thickness is connect, by priming by vacuum mode, laminate is made using multiaxis cloth and resin system and is replaced original bonding agent, from
And ensure that the direct adhesive thickness of the trailing edge produced.Compared with prior art, the beneficial effects of the utility model are：
It is overproof that this utility model effectively eliminates the direct bonding region thickness of trailing edge, improves the intensity and service life of blade,
Powerful guarantee is provided for leaf quality.This utility model is reasonable in design, simple to operate, effect is significant.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Referring to the drawings, concrete technical scheme of the present utility model is further described, in order to those skilled in the art
Member is further understood that the present invention, and does not constitute the restriction to its right.
Embodiment 1, with reference to Fig. 1, a kind of direct bonding region thickness-adjusting layer of fan blade trailing edge spreads structure：After blade
There is overproof region in the direct adhesive thickness of edge, if each pre-buried dried layer glass-fiber-fabric 2 in PS faces, SS faces in the region, glass-fiber-fabric exists
PS faces, SS faces are laid on the lower surface of Inner Mongol cortex 3, the upper surface of unidirectional layer of cloth 1, and the gentle mistake at edge is kept during laying
Cross, if forming the adjustment structure sheaf 4 of dried layer glass-fiber-fabric laying pre-buried in advance, adjust structure sheaf 4 by priming by vacuum
Mode and housing laying global formation.
The glass-fiber-fabric of the adjustment laying of structure sheaf 4 is biaxially glass-fiber-fabric or three axial glass-fiber-fabrics, laying direction from blade root to
Blade tip is carried out.The glass-fiber-fabric of the adjustment laying of structure sheaf 4 is using starting point is identical, the successively interior wrong laying structure of terminal.Adjustment structure
The PS faces glass-fiber-fabric of the laying of layer 4 is tangential need to fill the laying of trailing edge groove, against trailing edge typing line projection, the tangential paving of SS faces glass-fiber-fabric
Put away from trailing edge parting line 3-8mm.
Embodiment 2, describes the technical solution of the utility model in detail by taking UP86 blade profiles as an example below：As described in Figure 1, it is a kind of
The direct bonding region thickness-adjusting layer of fan blade trailing edge spreads structure, if forming including the dried layer laying of glass-fiber-fabric 2 pre-buried in advance
Adjustment structure sheaf 4, the adjustment structure sheaf is laid on the lower surface of Inner Mongol cortex 3, the upper table of unidirectional layer of cloth 1 in PS, SS face
Face；
During housing laying, there is overproof region in the direct adhesive thickness of trailing edge（Trailing edge L9.5m ~ blade tip）,
The each pre-buried 18 layers biaxially glass-fiber-fabric in PS, SS face, laying direction is carried out from blade root to blade tip；
Biaxially glass-fiber-fabric lay when, starting point is constant, the successively interior wrong 0.2-1m of terminal, PS faces glass-fiber-fabric is tangential need to fill after
Emargination groove is laid, and against trailing edge typing line projection, glass-fiber-fabric tangential lay in SS faces keeps away from trailing edge parting line 3-8mm during laying
The gentle transition at edge；
Pre-buried glass-fiber-fabric and housing laying global formation are made finally by the mode of priming by vacuum；
It is finally completed the adjustment to the direct bonding region thickness of trailing edge.
