Abstract

Et toppdrevet rotasjonssystemapparat for borehullsoperasjoner, hvilket toppdrevet rotasjonssystemapparat omfatter et hovedlegeme ( 130 ), en hovedaksel ( 160 ) som har en gjennomgående strømningsboring ( 163 ) for gjennomstrømning av borevæske, en hulaksel ( 190 ) som omgir i det minste en del av hovedakselen ( 160 ) og er drivende koplet til denne, og et motorapparat ( 120 ) som skal rotere hulakselen ( 190 ), kjennetegnes ved at et tannhjulssystem er anordnet mellom motorapparatet ( 120 ) og hulakselen ( 190 ) for å rotere hulakselen (190) og derved drive hovedakselen ( 160 ), idet hovedakselen ( 160 ) passerer gjennom tannhjulssystemet, hovedakselen ( 160 ) er uttakbar fra hovedlegemet ( 130 ) ved at hovedakselen (160) frakoples fra hulakselen ( 190 ) og hovedakselen ( 160 ) løftes ut av hulakselen ( 190 ).
