Claim Text:
1. A rudder propeller comprising a drive shaft ( 1 ) and a propeller shaft ( 4 ) driveable by the drive shaft ( 1 ) via an angular drive ( 2 ) and a planetary gearing ( 3 ), the planetary gearing ( 3 ) positioned on the propeller shaft ( 4 ) and comprising a sun gear ( 30 ) connected to the angular gear ( 2 ) via a coupling, a stationary ring gear ( 35 ), and planet gears ( 31 ) mounted on a planet carrier ( 33 ) and traveling between the sun gear ( 30 ) and the ring gear ( 35 ), and the planet carrier ( 33 ) connected to the propeller shaft ( 4 ) in a torsionally rigid manner, the coupling between the angular drive ( 2 ) and the sun gear ( 30 ) having a double-cardanically functioning, rotationally fixed compensation coupling ( 5 , 6 ) for compensation of radial and angular displacements of the sun gear ( 30 ) relative to the angular drive ( 2 ), wherein the ring gear ( 35 ) is mounted in a housing ( 37 , 37 a ) by elastically deformable flex pins ( 36 ) so that radial and tangential forces on the ring gear ( 35 ) are absorbed by the flex pins ( 36 ).
