Abstract

En trekkvinsj, særlig for bruk ombord i fartøy for å trekke en wire opp av havet og inn på en lagringstrommel. Trekkvinsj en omfatter to tromler (7, 8) anbrakt ved siden av hverandre med mansjetter (3, 4) med spor for en wire, hvor tro.v.lene er dreibart festet til et fundament ( 6). For å unngå at wiren kommer ut av sporet på den ene trommelen (7; 8) med en vinkel i forhold til sporet som den går inn på på den andre trommelen (8; 7) er tromlenes (7, 8) dreieakser vridd i forhold til hverandre med en vinkel « som er tilpasset stigningen av sporene i mansjettene (3, 4) på tromlene (7, 8). Med denne vridningsvinkelen « unngås tvinn på wiren, noe som ikke er ønskelig da dette over tid vil ødelegge wiren. Ved at tromlene er vridd i forhold til hverandre kan de anbringes nærmere hverandre enn tromlene fra den kjente teknikk slik at vinsjen blir mindre og lettere. Hver trommel (7, 8) er drevet direk- te av en motor (l, 2) slik at tromlene (7, 8) kan drives uavhengig med for- skjellig kraft fra hver motor.A towing winch, especially for use on board vessels to pull a wire up from the ocean and onto a storage drum. The pull winch comprises two drums (7, 8) arranged side by side with cuffs (3, 4) with grooves for a wire, the pulleys being pivotally attached to a foundation (6). In order to prevent the wire from coming out of the groove on one drum (7; 8) at an angle to the groove on which it enters on the other drum (8; 7), the rotational axes of the drum (7, 8) are twisted in proportion to one another at an angle 'adapted to the pitch of the grooves in the cuffs (3, 4) of the drums (7, 8). With this angle of rotation “twisting of the wire is avoided, which is not desirable as this will over time destroy the wire. By twisting the drums relative to each other, they can be placed closer together than the drums of the prior art so that the winch is smaller and lighter. Each drum (7, 8) is driven directly by a motor (1,2) so that the drums (7, 8) can be operated independently with different power from each motor.
