Claims (14)

1. Omdrejningsdrev til en vindmølle omfattende en aksel (52), en hydromotor (27) til at drive akslen (52) og en drivledning (39) til at tilføre en under tryk stående hydraulikvæske til hydromotoren (27), idet drivledningen (39) er forsynet med en indstillelig trykbegrænsningsventil (30), kendetegnet ved, at omdrejningsdrevet er indrettet således, at der kan tilsluttes en hurtig aksel (19) i et gear i vindmøllen, og der er tilvejebragt en mekanisk bremse (40) til akslen (52).
2. Omdrejningsdrev ifølge krav 1, kendetegnet ved, at bremsen (40) har en hydraulisk aktuator (28), idet der til aktuatoren (28) er tilsluttet en hydraulikvæske førende bremseledning (41), og idet bremsen (40) løsnes, når hydraulikvæsken står under tryk.
3. Omdrejningsdrev ifølge krav 2, kendetegnet ved, at der i bremseledningen (41) er placeret en indstillelig trykformindsker (24).
4. Omdrejningsdrev ifølge et af kravene 1 til 3, kendetegnet ved, at der er en forbindelsesledning (42) mellem hydromotoren (27) og bremsen (40).
5. Omdrejningsdrev ifølge krav 4, kendetegnet ved, at forbindelsesledningen (42) og bremseledningen (41) er forbundet med hinanden via en vekselventil (43), således at det højeste af de to tryk virker på aktuatoren (28).
6. Omdrejningsdrev ifølge et af kravene 1 til 5, kendetegnet ved, at en hjælpebremseledning (53) strækker sig hen til aktuatoren (28) for at tilføre hydraulikvæske til aktuatoren (28) , idet den indstillelige trykformindsker (24) omgås.
7. Omdrejningsdrev ifølge et af kravene 1 til 6, kendetegnet ved, at hydromotoren (27) er forsynet med en kortslutningsledning (22).
8. Omdrejningsdrev ifølge et af kravene 1 til 7, kendetegnet ved en omdrej ningsmoment sensor (37) til det mellem en drevenhed (31) i omdrejnings-drevet og en struktur i vindmøllen overførte omdrejningsmoment.
