In hole, the semicircle portion of arching upward can be entrenched in semi-circular recesses, and fixed block is arranged in semi-circular recesses edge, and fixed block is crescent
Structure, fixed block can be entrenched in the inside in the semicircle portion that arches upward, the interior arc radius of fixed block and the radius phase of vane hole fixed frame
Deng fixed block one end is hinged on semi-circular recesses edge by universal shaft, and the fixed block other end is provided with threaded hole, semi-circular arch
It plays portion and the corresponding position at semi-circular recesses edge and is both provided with the identical threaded hole of structure, screw bolt passes fixed block, partly
Circle arch upward portion and semi-circular recesses edge threaded hole by vane hole fixed frame with divide cover body to screw to connect.
Further, the universal shaft is spherical axis, and semi-circular recesses edge is provided with the spherical pore of accommodating universal shaft.
Further, it is provided with gasket on the vane hole fixed frame contact surface chimeric with vane hole, gasket is
Rubber pad.
Further, it is provided with arc reinforcing rib on the inner wall for dividing cover body.
Compared with the existing technology, a kind of wind generator unit wheel hub cover described in the invention has the advantage that：
(1) a kind of wind generator unit wheel hub cover described in the invention, will divide cover body to consolidate by vane hole fixed frame
It is scheduled on and overcomes together during carrying out point cover body assembly since vane hole caused by deformation loses the disadvantage of circle, it is ensured that wind
