Claims (14)

1. Vindmølleflangeforbindelse mellem et nav (1) og en nacelle, - hvor navet (1) af vindmøllen omfatter en første flange (2), - hvor nacellen af vindmøllen omfatter en anden flange (3), - hvor den første flange (2) og den anden flange (3) er forbundet med hinanden med et antal forbindelsesmidler (4) til overførsel af kræfter mellem den første flange (2) og den anden flange (3), - den første flange (2) omfatter en flerhed af huller (5), og den anden flange (3) omfatter en flerhed af huller (6), der svarer til hullerne (5) i den første flange (2), - hvor brudstifter (7) er anbragt i hullerne (5, 6) af flangerne (2, 3) til overførsel af rotationskræfter mellem navet (1) og nacellen, kendetegnet ved, at - brudstifterne (7) er anbragt ud over forbindelsesmidlerne (4) og mindst i en sektor (9, 10, 11) langs den første flange (2), hvor navet (1) udviser en lavere stivhed eller en høj gradient i stivheden.
2. Vindmølleflangeforbindelse ifølge krav 1, kendetegnet ved, at hullerne (5) i den første flange (2) og/eller hullerne (6) i den anden flange (3) til indsætning af brudstifterne (7) er blindhuller.
3. Vindmølleflangeforbindelse ifølge et af de foregående krav, kendetegnet ved, at navet (1) omfatter et forbindelsesområde (8), der er indrettet til at modtage en rotorvinge, og at brudstifterne (7) er anbragt i en sektor (9, 10, 11) langs den første flange (2) tæt på området (8) til forbindelse af en rotorvinge.
4. Vindmølleflangeforbindelse ifølge et af de foregående krav, kendetegnet ved, at navet (1) omfatter en åbning (12) til service- og vedligeholdelsesformål, og at brudstifterne (7) er anbragt i en sektor langs den første flange (2) tæt på åbningens (12) område.
5. Vindmølleflangeforbindelse ifølge et af de foregående krav, kendetegnet ved, at brudstifterne (7) er anbragt i området af den første flange (2) i umid- delbar nærhed af et mandehul (12) i navet.
6. Vindmølleflangeforbindelse ifølge et af de foregående krav, kendetegnet ved, at brudstifterne (7) er anbragt i tre sektorer (9, 10, 11) langs omkredsen af den første flange (2), som hver dækker op til en sjettedel af omkredsen af den første flange (2).
7. Vindmølleflangeforbindelse ifølge et af de foregående krav, kendetegnet ved, at flerheden af brudstifter (7) hovedsageligt er jævnt fordelt langs omkredsen af den første flange (2).
8. Vindmølleflangeforbindelse ifølge et af de foregående krav, kendetegnet ved, at flangeforbindelsen omfatter en cirkel af huller (13), der er anbragt og indrettet således, at de modtager forbindelsesmidlerne (4), og ved at brudstifterne (7) er anbragt udvendigt i radial retning i forhold til cirklen af huller (13).
9. Vindmølleflangeforbindelse ifølge et af de foregående krav, kendetegnet ved, at flangeforbindelsen omfatter en cirkel af huller (13), der er anbragt og indrettet således, at de modtager forbindelsesmidlerne (4), og ved at brudstifterne (7) er anbragt indvendigt i radial retning i forhold til cirklen af huller (13).
10. Vindmølleflangeforbindelse ifølge et af kravene 1 til 7, kendetegnet ved, at flangeforbindelsen omfatter en cirkel af huller (13), der er anbragt og indrettet således, at de modtager forbindelsesmidlerne (4), og ved at brudstifterne (7) er anbragt mellem hullerne (13).
11. Vindmølleflangeforbindelse ifølge et af de foregående krav, kendetegnet ved, at forbindelsesmidlerne (4) er bolte.
12. Vindmølle omfattende en flangeforbindelse ifølge et af kravene 1 til 12.
13. Nav (1) af en vindmølle til anvendelse i en flangeforbindelse ifølge et af kravene 1 til 12.
14. Nacelle af en vindmølle til anvendelse i en flangeforbindelse ifølge et af kravene 1 til 12.
