Abstract

Verktøyskjøt (1) for borerør brukt ved boring av olje- eller gassbrønner. Tappen 3 er forsynt med en utvendig skulder (35), en tappbunn (34) med en utvendig perifer overflate parallelt med røraksen 50, en hanngjenget del (33) med en bestemt avskråning i forhold til røraksen (50), og en tappnese (32) med utvendig perifer overflate parallelt med røraksen (50). Kapselmutteren (2) er forsynt med en kapselmutteraksesshylse (22) med en innvendig perifer overflate parallelt med røraksen (50), en hunngjenget del (23) som er i inngrep med den hanngjengede del (33), en kapselendehylse (24) med en innvendig perifer overflate tilsvarende den utvendige perifere overflate av tappnesen (32) og en innvendig skulder (25). Ved å øke den totale tilpasningsflate mellom den utvendige skulder (35) og en kapselaksesshylses endedel (21) og en tilpasningsflate mellom den innvendige skulder (25) og tappnesens endedel (31), blir et høyere dreiemoment realisert uten åredusere bruksevnen.
