Abstract
The utility model relates to a hubcap of a wind driven generator. The hubcap comprises a hubcap body. Three blade holes of the same size are uniformly distributed on equal circumferential faces of the hubcap body. Three uniformly divided same hubcap fragments are spliced to form the hubcap body, so that logistics cost is greatly saved, and manufacturing difficulty of the hubcap is also greatly reduced. The hubcap fragments are divided from a position which is 45-60 degrees relative to each blade hole axis, and accordingly out-of-round situation caused by splicing or deformation of the hubcap fragments is reduced, roundness of the blade holes is well guaranteed, and mounting efficiency of the blades is greatly improved. Furthermore, due to the fact that the fragments are divided by keeping off the blade holes, flange side lines are greatly prolonged, intensity and rigidity of the spliced hubcap body are greatly improved.
Description
Technical field
The utility model 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 has included 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 bigger, adopt integrated type production logistics cost higher, so all adopt full circle average mark 1/3rd modes to produce the back on-site consolidation; 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.
The model utility content
The purpose of the utility model is to provide a kind of and can avoids hub of wind power generator cover blade installation bore deformation and make impregnable hub of wind power generator cover.
The technological scheme that realizes the utility model purpose is: the utlity model has the hubcap body; Three vane holes that size is identical uniformly distribute on the anchor ring such as grade of said hubcap body circumference.Said hubcap body is to be spliced by three identical hubcap bursts that average mark is slit into.Said hubcap burst is to cut apart from spending with respect to each vane hole axis 45 to the position of 60 degree.
Above-mentioned hubcap burst is from cutting apart with respect to the position of each vane hole axis 45 degree.
The utlity model has positive effect: (1) the utility model can not produce owing to the distortion of assembly unit and product itself causes the situation of losing circle; Can guarantee the sufficient degree of circle (blade of wind-driven generator need pass this hole and install, so the sufficient degree of the circle in hole is important) well; (2) the flange sideline of the utility model is very long, be to open more than 3 times of offshoot program from circular hole, so the strength and stiffness after its connection improves greatly; (3) processing and fabricating of the hubcap burst of the utility model more is tending towards convenient, better quality, and practicability is higher.
Description of drawings
For the content that makes the utility model is expressly understood more easily,, the utility model is done further detailed explanation, wherein below according to specific embodiment and combine accompanying drawing
Fig. 1 is the schematic representation of the utility model;
Fig. 2 is the single hubcap burst of a utility model 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 utlity model has hubcap body 1; Three vane holes 11 that size is identical uniformly distribute on the anchor ring such as grade of said hubcap body 1 circumference.Said hubcap body 1 is to be spliced by three identical hubcap bursts 12 that average mark is slit into, and has saved LOGISTICS COST so greatly, has also reduced the manufacture difficulty of hubcap body 1 greatly.Said 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, improved the installation efficiency of blade greatly.And, the strength and stiffness of its spliced hubcap body 1 are improved greatly because burst has been avoided vane hole and made the flange sideline increase greatly.
Above-described specific embodiment; Purpose, technological scheme and beneficial effect to the utility model have carried out further explain, it should be understood that the above is merely the specific embodiment of the utility model; Be not limited to the utility model; All within the spirit and principle of the utility model, any modification of being made, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
