Abstract
The invention relates to a wind power generator hubcap provided with a hubcap body. Three blade holes which are same in size are distributed on equal torus of the circumference of the hubcap body. The hubcap body is formed by split-jointing three hubcap split sheets which are cut evenly and are the same in size, so that logistics cost is reduced greatly, and difficulty in manufacturing the hubcap is also reduced greatly. The hubcap split sheets are cut at the positions at forty five degrees and at sixty degrees corresponding to the hole axis of each blade, distortion caused by split jointing or deformation of the hubcap split sheets is reduced, fine roundness of the blade holes is guaranteed, and mounting efficiency of the blades is improved greatly; since the split sheets avoid the blade holes, so that the flange edge is increased greatly, and strength and rigidity of split-jointed hubcap body are improved greatly.
Description
Technical field
The present invention relates to the critical piece of large-scale wind driven generator equipment, particularly a kind of hub of wind power generator cover.
Background technique
Along with the further demand of China to the clean environment energy, country includes wind power technology in the important industry pillar of the following national economic development in Eleventh Five-Year Plan, and clearly proposes to increase the wind-power electricity generation electric motor power.The emergence in wind-powered electricity generation field has brought opportunities and challenges for supporting with it engine room cover.
As everyone knows, the volume of wind-driven generator is very huge, therefore how to satisfy wind-powered electricity generation installation safety and usage requirement, and the rationality of product specification just becomes the core of engine room cover technology.The hubcap of large-scale wind driven generator mostly adopts glass fibre reinforced plastics to make at present, because the hubcap volume is larger, adopt monolithic green product stream cost higher, produce rear on-site consolidation so all adopt full circle average mark 1/3rd modes, for easy to process, 1/3rd split the center division that circular hole is installed from three fan blades of hubcap, but this method for splitting can cause the distortion of fan blade mounting hole, the difficulty when causing on-site consolidation.
Summary of the invention
The object of the present invention is to provide and a kind ofly can avoid hub of wind power generator cover blades installation bore deformation and make impregnable hub of wind power generator cover.
The technological scheme that realizes the object of the invention is: the present invention has the hubcap body; Three vane holes that size is identical uniformly distribute on the anchor ring such as grade of described hubcap body circumference.Described hubcap body is to be spliced by three identical hubcap bursts that average mark is slit into.Described hubcap burst is from cutting apart to the position of 60 degree with respect to each vane hole axis 45 degree.
Above-mentioned hubcap burst is from cutting apart with respect to the position of each vane hole axis 45 degree.
The present invention has positive effect: (1) the present invention can not produce owing to the distortion of assembly unit and product itself causes the situation of losing circle, can guarantee well the sufficient degree of circle (blade of wind-driven generator need to pass this hole and install, so the sufficient degree of the circle in hole is important); (2) flange of the present invention sideline is very long, is to open more than 3 times of offshoot program from circular hole, so its strength and stiffness after connecting improve greatly; (3) processing and fabricating of hubcap burst of the present invention more is tending towards convenient, better quality, and practicability is higher.
Description of drawings
Content of the present invention is easier to be expressly understood in order to make, and the below is according to specific embodiment and by reference to the accompanying drawings, and the present invention is further detailed explanation, wherein
Fig. 1 is schematic representation of the present invention;
Fig. 2 is the single hubcap burst of the present invention plan view;
Fig. 3 is the left view of Fig. 2;
Fig. 4 is the rear view of Fig. 2.
Embodiment
See Fig. 1 to Fig. 4, the present invention has hubcap body 1; Three vane holes 11 that size is identical uniformly distribute on the anchor ring such as grade of described hubcap body 1 circumference.Described hubcap body 1 is to be spliced by three identical hubcap bursts 12 that average mark is slit into, and has so greatly saved LOGISTICS COST, has also greatly reduced the manufacture difficulty of hubcap body 1.Described hubcap burst 12 is from cutting apart with respect to the position of each vane hole 11 axis 45 degree, reduced because of the round situation of mistake of splicing or 12 distortion of hubcap burst own cause, well guarantee the circularity of vane hole 11, greatly improved the installation efficiency of blade.And because burst has been avoided vane hole so that the flange sideline increases greatly, the strength and stiffness of its spliced hubcap body 1 are improved greatly.
Above-described specific embodiment; purpose of the present invention, technological scheme and beneficial effect are further described; institute is understood that; the above only is specific embodiments of the invention; be not limited to the present invention; within the spirit and principles in the present invention all, any modification of making, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
