Claims (6)

1. Pitch-leje for en vindmøllerotor (5) med et rotornav (7) og mindst en rotorvinge (9), hvilket pitch-leje omfatter en cylindrisk indvendig lejering (13), der kan forbindes med en rotorvinge (9) af vindmøllerotoren (5), en cylindrisk udvendig lejering (15), der kan forbindes med rotornavet (7) af vindmøllerotoren (5), og en ringformet forstærkningssektion (21) til forstærkning af den udvendige lejering (15), hvor den ringformede forstærkningssektion (21, 31, 33) grænser op til den cylindriske udvendige lejering (15) ved den radiale udvendige flade og er dannet af en øget vægtykkelse af den udvendige lejering (15) i et ringafsnit, der grænser op til det udvendige lejes aksiale udvendige ende hen imod den aksiale indvendige ende (25), kendetegnet ved, at vægtykkelsen af den udvendige lejering (15) aftager kontinuerligt fra et afsnit af en konstant vægtykkelse, hvilket afsnit befinder sig ved den aksiale udvendige ende (23), hen imod den aksiale indvendige ende (25) af den udvendige lejering.
2. Pitch-leje ifølge krav 1, kendetegnet ved, at vægtykkelsen af den udvendige lejering (15) er konstant fra omkring midten af den udvendige lejering (15) til den udvendige lejerings aksiale indvendige ende (25).
3. Pitch-leje til en vindmøllerotor (5) med et rotornav (7) og mindst en rotorvinge (9), hvilket pitch-leje omfatter en cylindrisk indvendig lejering (13), der kan forbindes med en rotorvinge (9) af vindmøllerotoren (5), en cylindrisk udvendig lejering (15), som kan forbindes med rotornavet (7) af vindmøllerotoren (5), og en ringformet forstærkningssektion (31, 33) til forstærkning af den udvendige lejering (15), kendetegnet ved, at de i det mindste to separate ringsegmenter (31,33) grænser op til den radiale udvendige flade af den cylindriske udvendige lejering (15); og forstærkningssektionen (31, 33) består af mindst to separate ringsegmenter (31,33), som er indrettet således, at de kan sammenføjes og kan sammenfø- jes med den udvendige lejering (15).
4. Pitch-leje ifølge krav 3, kendetegnet ved, at de i det mindste to separate ringsegmenter (31, 33) er indrettet således, at de kan sammenføjes løsbart og/eller kan sammenføjes løsbart med den udvendige lejering (15).
5. Pitch-leje ifølge krav 4, kendetegnet ved, at de i det mindste to separate ringsegmenter (31, 33) er indrettet således, at de kan sammenføjes løsbart ved hjælp af en sammenboltning.
6. Vindmølle, der omfatter en rotor (5) med mindst et pitch-leje ifølge et hvilket som helst af kravene 1 til 5.
