Definitions

  • the invention relates to an electrically driven propeller for watercraft with the features of the preamble of claim 1.
  • Motor propellers are known in which the propeller runs in a nozzle which receives the stator winding distributed around the circumference. The wing ends of the propeller are connected to each other by a strap. Permanent magnets to excite the motor are inserted in the belt, also distributed over the circumference.
  • Such a motor propeller is described in DE application P 32 46 730.3 and brings with it a significant improvement in efficiency compared to drives which are driven by the propeller hub (cf. DE-C-688114 and DE-C-690 233, which the preamble of Claim 1 corresponds).
  • the object underlying the invention is therefore to be seen in creating an arrangement of the type described at the outset with which an optimal degree of propulsion quality is achieved with maximum propeller dimensions. This object is achieved by the features specified in the characterizing part of claim 1.
  • the arrangement according to the invention has significant advantages. If the stator winding is placed in the stern ship, which is adapted to the motor propeller, there is maximum utilization of the diameter of the propeller. A further improvement in effectiveness can be achieved if the outer shell of the ship, which surrounds the propeller motor in a two-screw ship, is made into a tunnel. This partial tunnel can be closed by a nozzle ring. By eliminating the wave trousers and the wave line and appropriate design of the stern, a uniform flow is achieved. This increases the overall degree of propulsion.
  • Fig. 1 From Fig. 1 it can be seen that the two propellers 1 and 2 are inserted into the stern 3 so that they run in a tunnel-like recess 4.
  • the special design of the stern ship 3 in the form of a fin-like extension 5 of the keel leads to a more than 50% tunneling of the propellers 1, 2.
  • a partial nozzle ring 6 can be inserted into the partial tunnel to completely surround the propellers.
  • This structurally simpler form of the stern ship 3 leads to a more uniform flow against the propellers 1, 2 and, in the favorable case, can lead to an approximately 20% increase in the overall degree of propulsion quality.
  • Fig. 2 From Fig. 2 it can be seen more clearly that the propellers 1, 2 are integrated into the stern 3.
  • the tunnel-shaped recesses 4 are supplemented by the nozzle rings 6, so that the stator windings can be distributed evenly over the circumference of the propellers.
  • the shaft brackets 8 which are used to hold the propeller shafts 7 and are firmly connected to the ship's hull are indicated. With this design of the stern, the draft of the ship is not exceeded, even with optimal propeller diameters.
  • FIGS. 4 and 4 show the stern of a screw-in ship. Due to its construction, the propeller 10 runs only about 1/3 of its circumference in a tunnel 12 integrated into the stern 11, while about 2/3 are formed by a nozzle ring 13.
  • the bearing of the propeller shaft 14 and the absorption of the thrust forces can take place in the fixed part 15 of a semi-floating rudder 16, alternatively also in a bridge to the rudder hoe 17. Radial forces can be absorbed by articulated arms 18.
  • stator winding 19 is distributed over the tunnel 12 and the nozzle ring 13.
  • the excitation of the motor is generated by permanent magnets 20, which are also distributed over the circumference of the propeller in a belt 21.
  • the stator winding 19 is expediently fed by a separate generator and designed with a voltage corresponding to the vehicle electrical system voltage. This means that if the main machine fails, takehome operation is possible via the vehicle electrical system generators and converters.
  • the ship's outer skin can be designed as a tear-off edge or drainage bead 24, also removable (FIG. 5b). This embodiment is dealt with in more detail using the following description of the figures.
  • FIG. 6 shows a variant in which the wing ends of the propeller 25 are connected to an annular disk 26.
  • Permanent magnets 27, 28 are embedded in the opposing ring surfaces distributed over the circumference.
  • the annular disc 26 runs in an annular groove 29 of the partial tunnel and the nozzle ring, which are made correspondingly stronger in the wall.
  • the rotor is designed like an axial field double rotor.
  • the stator windings 30, 31 are arranged on both sides of the annular groove 29.
  • the propeller shaft 32 is mounted both on the fixed part 33 of the rudder and on the ship's outer skin by means of articulated arms 34 in order to absorb the thrust and transverse forces.
  • the gap between the annular disc 26 and the annular groove 29 is flooded and provided with a coarse seal 35 at the entrance in order to keep foreign objects away.
  • FIG. 7 which shows the part circled in a circular manner in FIG. 6, it can be seen that the rear stator winding 31 is arranged in an annular bead 36 which ends at the end 37 in a streamlined manner in order to reduce the water resistance.
  • the annular bead 36 can be removed aft.
  • the parting line can run in the middle of the web ring 38.
  • Peripheral openings 39 can be provided in the web ring on the water side in order to ensure flushing of the flooded annular gap and cooling of the motor.
  • annular disk and the annular groove according to FIG. 6 are L-shaped by lugs parallel to the propeller axis, the electrically active components being placed in the horizontal parts.
  • An annular disk 41 is in turn connected to the wing ends of the propeller 40, but is provided with a horizontal shoulder 42 parallel to the propeller axis. This has opposite surfaces and distributes permanent magnets 43, 44 over the circumference.
  • the annular groove 45 receiving the L-shaped rotor, which acts here as a radial field double rotor, in the partial tunnel of the stern and in the nozzle ring has stator windings 46, 47 in the surfaces opposite the rotor magnets.
  • the wing ends can be brought close to the inner wall of the tunnel or nozzle ring.
  • the annular groove receiving the radial part 41 of the rotor can be made relatively wide and in turn receives a coarse seal 48 at the entrance.
  • stator windings 46, 47 are placed in an annular bead 50 connected to the stern, for example via bolts 49. This facilitates maintenance and repair of the propeller 40. Openings 51 to the water side in the annular bead can also be provided here.
