Definitions

  • the invention relates to a ship propulsion system with a hubless propeller.
  • propellers have become known from EP 1 739 007 AI.
  • the essential components of a hubless propeller are the following:
  • a rotor has a plurality of rotor blades which point radially inwards.
  • the rotor carries a variety of permanent magnets.
  • a stator surrounds the rotor.
  • the stator has or consists of a stator laminated core.
  • the invention has for its object to make a marine propulsion with a hubless propeller of the above type such that it can achieve an efficient cooling with seawater, and that at the same time the corrosion problem is solved.
  • FIG. 1 shows a schematic very general representation of one
  • Figure 2 shows in an axial section in an enlarged view essential
  • FIG. 3 shows a schematic representation of a transverse jet drive
  • the hubless propeller shown in Figure 1 comprises a rotor 1 and a stator 2.
  • the propeller can serve as a main propulsion for a ship. He can also serve the lateral control of a ship. Thus, it can be installed in the hull of a ship and produce in operation a jet of water that runs horizontally and perpendicular to the longitudinal axis of the ship and exits to port or starboard from the ship's skin.
  • the rotor shown in Figure 2 is constructed as follows:
  • rotor ring 3 made of carbon steel. This is at its two axial ends of two support rings 4 made of stainless steel or a
  • connection between the rotor ring 3 and 4 support rings for example, a welded joint - see the weld 5.
  • a welded joint - see the weld 5.
  • another type of connection is conceivable.
  • Rotor ring 3 carries a plurality of permanent magnets 6. These have, for example, rod shape and can be arranged axially parallel or perpendicular to the axis.
  • the magnets are covered by a stainless steel sleeve 7. This is fixed with its axial end portions of the support rings 4, 4. As you can see, they are
  • the fixation can be done by laser welding.
  • the weld 8 is located in the axial direction as far as possible at the end of the two support rings 4, 4. This results in welding only a small amount of heat in the region of the permanent magnets 6, and thus does not affect their magnetic force.
  • the welding process using a laser welding process also contributes to this.
  • Permanent magnets 6 remains a gap of, for example, 2 mm. Also, the gap may have a lower thickness, for example, up to 0.5, or a greater thickness, for example, up to 5 mm.
  • All clearances between sleeve, magnet carrier and magnets are filled with a mass such as a resin-hardener mixture.
  • the rotor blades are not shown here. They extend radially inwards towards the axis of rotation.
  • Rotor 1 is enclosed by the stator 2.
  • the stator is not shown here.
  • Figure 3 shows a hubless propeller according to the invention as part of a transverse jet propulsion. This is installed in the bow of a ship.
  • the axis of rotation of the hubless propeller 1.3 also runs perpendicular to the ship's longitudinal axis.
  • the transverse jet drive is seated in a Strömungsleitgephaseuse 10, which in turn is arranged in a tunnel, see the tunnel wall 11, which is part of the ship.
  • the StrömungsleitgephasePSuse 10 is formed nozzle-like at its two ends. See the two nozzles 10.1 and 10.2.
  • the nozzles 10.1 and 10.2 are associated with current-carrying strips 12, which form a grid with each other.
  • Slit flow contributes significantly to the cooling of the motor formed by the rotor and stator. It thus runs in addition to the above-mentioned flow between tunnel wall 11 and stator housing 2.1.
