Abstract
A rudder propeller including a drive shaft and a propeller shaft that can be driven by the drive shaft by an angular drive and a planetary gear that can be located on the propeller shaft and including a sun gear that is connected to the angular drive via a coupling, a fixed ring gear and planet gears that revolve between the sun gear and ring gear and that are mounted on a planet carrier. The planet carrier can be secured against torque to the propeller shaft and the coupling between the angular drive and the sun gear can be designed as a double cardanic, rotationally-fixed flexible coupling, in such a way that radial and angular displacements of the sun gear in relation to the angular drive can be compensated.

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).
The rudder propeller according to 4, wherein the flex pins (36) are supported without play in the ring gear (35) and the housing (37, 37a).
