1. Indretning til regulering af hældningsvinklen af en rotorvinge af en vindmølle med - en pitch-aktuator i form af en pitch-hydraulikcylinder (1) eller en elektrisk pitch-aktuator, som virker på et reguleringsplan (P, 41) til regulering af hældningsvinklen, og - en fastgørelsesindretning (2), hvortil pitch-aktuatoren (1) er fastgjort, og der tjener som fastgørelse til et nav (40) af en vindmølle, hvor fastgørelsesindretningen (2) omfatter en første og anden lejeaksel (A, B), som muliggør en pendulbevægelse af pitch-aktuatoren (1) i forhold til fastgørelsesindretningen (2), hvor både den første og anden lejeaksel (A, B) hver især er anbragt under en vis hældningsvinkel (a) i forhold til reguleringsplanet (P, 41), hvor hældningsvinklen (a) er henholdsvis i det væsentlige forskellig fra 0° eller 90°.
2. Indretning ifølge krav 1, hvor den første og anden lejeaksel er anbragt i det væsentlige vinkelret i forhold til hinanden.
3. Indretning ifølge krav 1 eller 2, hvor den første og anden lejeaksel (A, B) i det væsentlige er anbragt i et fælles plan.
4. Indretning ifølge et hvilket som helst af kravene 1 til 3, hvor den første og/eller den anden lejeaksel (A, B) i det væsentlige er anbragt under en hældningsvinkel (a) i området fra +10° til +80° eller -10° til -80° i forhold til reguleringsplanet (P, 41).
5. Indretning ifølge et hvilket som helst af kravene 1 til 4, hvor den første lejeaksel (A) i det væsentlige er anbragt under en hældningsvinkel (a) på -45° i forhold til reguleringsplanet (P, 41), og hvor den anden lejeaksel (B) i det væsentlige er anbragt under en hældningsvinkel (a) på +45° i forhold til reguleringsplanet (P, 41).
6. Indretning ifølge et hvilket som helst af kravene 1 til 5, hvor mindst to lejer (32, 33) er tildelt den første lejeaksel (A), hvor de to lejer (32, 33) af den første lejeaksel (A) er fastgjort til et første ringlignende element (20) af fastgø- 2 relsesindretningen (2).
7. Indretning ifølge et hvilket som helst af kravene 1 til 6, hvor mindst to lejer (35, 36) er tildelt den anden lejeaksel (B), hvor de to lejer (35, 36) af den anden lejeaksel (B) er fastgjort til et tredje ringlignende element (34) af fastgørelsesindretningen (2), som er forbundet med henholdsvis en lejedel (32a, 33a) af lejerne (32, 33) af den første lejeaksel (A).
8. Indretning ifølge krav 6 eller 7, hvor mindst ét leje er et glideleje (32, 33, 35, 36).
9. Indretning ifølge et hvilket som helst af kravene 1 til 8, hvor fastgørelsesindretningen (2) omfatter mindst ét fastgørelsesmiddel (38).
