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.
Claims12
Input shaft that transmits torque from a ship drive to a ship propeller of a ship, the input shaft comprising:
- input-side and output-side interfaces, and at least one composite hollow shaft made of fiber composite material arranged therebetween,
- wherein the input shaft has at least one non-flammable section arranged between the input-side and output-side interfaces,
- wherein the at least one non-flammable section is made of non-flammable material,
- wherein the at least one non-flammable section comprises a metal pipe, and
- wherein the metal pipe is closed with a metallic cover on one side or on both sides.
Ship comprising:
- a hull, at least one bulkhead running transversely to the longitudinal axis of the hull, a motor, and an input shaft for the torque-transmitting connection of motor and gearbox,
- wherein the input shaft is fed through the bulkhead and has at least one composite hollow shaft made of fiber composite material,
- wherein the input shaft has at least one non-flammable section which is arranged in the region of the feedthrough through the bulkhead, is connected to the composite hollow shaft, is made of non-flammable material, and comprises a metal pipe, and
- wherein the metal pipe is closed with a metallic cover on one side or on both sides.
