Abstract

En marin fremdriftsenhet omfatter to kontra- roterende propeller (15, 16) som drives av én enkelt aksel (25) ved hjelp av en veksel som omfatter et sett av statiske planethjul (40), et ytre tannhjul (30) og et indre tannhjul (44). Vekselen er montert i en oljefylt gearkasse omfattende tre koaksiale, sylindriske seksjoner (12, 13, 14). De to seksjoner (12, 14) roterer i motsatte retninger og utgjør respektive popellnav. Den mellomliggende seksjon (13) er stasjonær og tjener som bærer for planethjul- ene (40) og en monteringsanordning for strømningsut- rettende skovler (18) som understøtter et sylindrisk deksel (17). En ringformet passasje (28) vil kunne anordnes i den mellomliggende seksjon (13) for å slippe ut forbrenningsgass gjennom åpninger i ytter- siden av dekselet (17) når enheten utgjør en del av en en påhengsmotor.
