  • Patent number: 9701386
    Abstract: An input shaft for the torque-transmitting connection of motor and propeller of a ship drive has input-side and output-side interfaces and a composite hollow shaft made of fiber composite material arranged therebetween. The input shaft has a section which is arranged between the input-side and output-side interfaces, is connected to the composite hollow shaft, and is made of non-flammable material. A ship includes a hull, a bulkhead running transversely to the longitudinal axis of the hull, a motor, a propeller and an input shaft described above. The input shaft of the ship is fed through the bulkhead and has the non-flammable section arranged in the region of the feedthrough through the bulkhead.

  • Patent number: 9028333
    Abstract: A shaft for transmitting torques includes a hollow shaft made of fiber-reinforced plastic. A flange which can be used to connect the hollow shaft to a driving or driven machine part is fastened at least to one end of the hollow shaft. The flange is fastened to the hollow shaft via a number of screw connections. Each screw connection includes a screw and a nut. The shank of the screw projects in the direction of the hollow shaft through an opening in the flange that is arranged in the connection region between the end edge of the hollow shaft and the flange. The shank extends at least partially inside the shell of the hollow shaft and engages with the nut arranged on the hollow shaft. The head of the screw is supported on that side of the flange opposed to the hollow shaft.
