  • the invention relates to a ship propulsion system according to the preamble of
  • Claim 1 and equipped with such a ship propulsion system ship or boat.
  • the invention has for its object to provide a cost-effective and compact ship propulsion system with elastically mounted engine and fixedly mounted thrust bearing. It is another object of the invention to provide a ship equipped with such a marine propulsion system.
  • a ship propulsion system comprising: a propelling member for propelling a ship, a propulsion engine flexibly attached to a hull of the ship To support the ship is to drive the Thebelements, a thrust bearing, which is rigidly to be stored on the hull and having a thrust bearing shaft with a first end and a second end, an engine driveline for connecting the prime mover to the first end of the thrust bearing shaft and a drive element driveline for connecting the second end of the thrust bearing shaft to the drive element.
  • the marine propulsion system according to the invention is characterized in that the prime mover driveline rigidly, in particular directly, connects or couples with the first end of the thrust bearing shaft.
  • the solution according to the invention provides a cost-effective and compact ship propulsion system. Due to the fact that the prime mover driveline rigidly engages the prime mover, i. axially rigid and radial rigid, connects to the first end of the thrust bearing shaft, can be dispensed with in favor of cost savings on additional couplings, in particular additional elastic or flexible couplings in the prime mover powertrain. This also results in the constructive possibility of making the engine driveline shorter and radially smaller and thus compact, which results in a smaller footprint in the engine room of the ship.
  • the prime mover may e.g. be formed by an electric motor or by an internal combustion engine, such. a diesel engine, a gasoline engine or a gas engine.
  • the prime mover drive train is formed by a single, one-piece engine shaft.
  • the prime mover powertrain can be made even more cost effective and compact. Furthermore, by the simple realization with only a single one-piece engine shaft, which is connected via respective flange with an output shaft of the Anhebsmaschine and the first end of the thrust bearing shaft, the maintainability and ease of installation of the marine propulsion system according to the invention improves.
  • the thrust bearing on a housing and guide means for rotatable axial guidance of the thrust bearing shaft and damping elements for damping vibrations, wherein the damping elements between the guide means and the housing are arranged.
  • This embodiment of the thrust bearing of the ship propulsion system achieved by the arrangement of the damping elements between the guide means and the housing advantageously a structure-borne sound insulation between thrust bearing and hull.
  • this configuration of the thrust bearing of the ship propulsion system allows, within certain limits, a tilting of the thrust bearing shaft with respect to its axial direction caused by a radial displacement of the engine and thus of the first end of the thrust bearing shaft.
  • This is made possible on the one hand by a predetermined elasticity or flexibility of the damping elements, which are preferably made of an elastomer material, and on the other hand by the hydraulic unit connected in the ring line and by a predetermined elastic flexibility of the axial bearing shaft.
  • the damping elements have a certain Shore hardness, wherein the damping elements are removably received in the housing, so that the damping elements are interchangeable with damping elements of other Shore hardness.
  • the damping effect of the damping elements in particular their elasticity or flexibility, can be adjusted or changed in a simple manner by exchanging the damping elements of a Shore hardness for damping elements of other Shore hardness.
  • the housing with respective lids closed openings through which the damping elements without complete disassembly of the thrust bearing are interchangeable.
  • the damping elements are biased against the guide means, wherein a respective biasing force of the damping elements is variable.
  • the damping effect or the tiltability can additionally be set or changed in a simple manner by changing the respective prestressing force on the damping elements.
  • the thrust bearing is a sliding bearing, wherein sliding surfaces of the guide means are supported via the damping elements on the housing of the thrust bearing.
  • the guide means on the sliding surfaces fitting sliding shoes, which are supported on the damping elements on the housing.
  • a respective hydraulic unit is provided for further damping between the respective shoe and respective damping element.
  • the respective hydraulic units via a ring line are hydraulically connected to each other.
  • a ship is provided which is equipped with a marine propulsion system according to one, several or all of the previously described embodiments of the invention in any conceivable combination with each other.
  • the term ship is used to subsume any water vehicles using the Archimedean principle for swimming in or on the water, such as e.g. also submarines, yachts and naval vessels.
  • Fig. 1 shows a schematic view of a ship propulsion system according to an embodiment of the invention.
  • FIG. 2 shows a schematic enlarged view of the thrust bearing of the marine propulsion system of FIG. 1.
  • FIG. 3 shows a view similar to FIG. 2 of the thrust bearing of FIG
  • FIG. 1 shows a marine propulsion system 1 integrated into a ship (not fully shown and not separately designated) according to an embodiment of the invention.
  • the ship is designed as a submarine.
  • the ship propulsion system 1 has a propulsion element 10 designed to propel the ship, in the form of a propeller or a propeller as here electric motor formed drive machine 20 for rotational driving of the drive element 10 and a thrust bearing 30.
  • the thrust bearing 30 is rigidly mounted or supported via a fixed bearing 40 (see FIG. 3) on a foundation (not designated) provided on a hull (not shown) of the ship.
  • the thrust bearing 30 has an axial bearing shaft 31 with a first end 31 a and a second end 31 b. At each end of the thrust bearing shaft 31, there is provided a connecting flange 32a and 32b, respectively.
  • the drive element 10 is attached to one end of a drive element shaft 11, which is mounted or supported on the hull via radial bearings 12, 13.
  • a connecting flange 14 is provided which is rigidly connected via screw connections, not shown, to the connecting flange 32 b provided at the second end 31 b of the axial bearing shaft 31.
  • the drive element shaft 11 thus forms a drive element drive train for connecting the second end 31 b of the thrust bearing shaft 31 to the drive element 10.
  • the drive machine 20 is flexibly supported or supported on the foundation provided on the hull of the ship by means of elastic or flexible bearings 21, so that structure-borne noise or vibrations generated by the drive machine 20 are decoupled from the hull or not or only minimally be transferred to this.
  • the engine 20 further includes an output shaft 22 to which a single, integral drive motor shaft 50 is flanged via a flange 51.
  • a further connecting flange 52 is provided, which is rigidly connected via screw connections, not shown, with the provided at the first end 31 a of the axial bearing shaft 31 connecting flange 32 a.

  • the thrust bearing 30 has a housing 33 which is rigidly fixed, i.e. fixed, over the fixed bearings 40. without the interposition of vibration damping materials, is connected to the foundation provided on the hull.
  • the housing 33 passes through the Axiallagerwelle 31, which has a shaft collar 34 which is supported on both sides by sliding shoes 35. That is, on both sides of the shaft collar 34 a plurality of sliding blocks 35 are provided, which are arranged in a circle around the axial bearing shaft 31 around and are axially movably guided in the housing 33.
  • damping elements 36 can be exchanged for damping elements 36 with other Shore hardness, whereby the damping effect can also be set specifically.
  • damping elements 36 of certain Shore hardnesses By combining damping elements 36 of certain Shore hardnesses with different bias voltages, the damping effect can be varied over a wide adjustment range, and optimal body sound insulation between the bearing inner parts and the housing 33 can be achieved for many applications.
  • a significant advantage of the thrust bearing 20 is the fact that drive vibrations are damped directly where they are introduced into the thrust bearing 30.
