Definitions

  • the invention relates to a ship propulsion system with a Engine and a rudder double propeller, which drives over drive shafts, Angular gearboxes and gearbox output shafts from the prime mover is powered, the propeller are rotatably connected to the output shafts.
  • a ship propulsion of this type is known from DE 870 655.
  • the performance of the inboard engine is introduced into a vertically arranged drive shaft, the lower end out through the ship's floor is guided, horizontally arranged there via angular gear Drives output shafts, each on the respective bevel gear opposite end to the propulsion of the ship serving propeller.
  • Such a system can be used as Rudder propeller be formed by the top of the vertical arranged shaft not only initiated the drive power is brought into effect, but an actuator can be that a concentrically surrounding the drive shaft Cladding tube around the longitudinal axis of the drive shaft by up to can be swiveled 360 ° or all around.
  • each propeller is an angular gear and each associated with an output shaft. This means that both propellers can be driven independently of one another. However, the technical effort of this drive stands not in proportion to the benefit from the separate mode of operation the two propellers can be achieved.
  • propeller arrangement for driving of a ship are at the bottom of one or two vertical ones drive shaft surrounding a housing tube or Drive shafts with the interposition of an angular drive two horizontal propeller shafts arranged and the Angle drive is facing away from the ends of the propeller shafts assigned to one of two propellers in a rotationally fixed manner.
  • the angular drive is designed so that between the lower shaft end or lower vertical shaft ends of the vertical shaft or of the vertical waves and each of the horizontal waves an angular gear of the angular drive is arranged.
  • the two propeller shafts, which are also gearbox output shafts are arranged on one side of this drive housing or one on each side of the drive housing Propeller shafts arranged and accordingly from the drive housing led out.
  • the invention has for its object a marine propulsion system to develop the type mentioned at the outset, with the contribution a high degree of efficiency in terms of production technology is constructed.
  • Both propellers are functionally the same with only one Angular gear and a drive train operated. So that is a much simpler compared to the prior art and less susceptible drive created, with which the construction volume is significantly reduced.
  • a guide device is known from DE 293 611, however, this is a Propeller arrangement with horizontal drive shaft, i.e. a propeller system without rudder function.
  • the angular gear and the output shaft are in the Usually surrounded by a housing that at the same time Bearing of the output shaft and the angular gear serves.
  • this housing with the guide device a fixed Unit while the one surrounding the drive shaft Housing tube preferably designed as a guide vane is. This will be the intermediate area between the two Flow-wise optimal propellers for one effective guidance device used.
  • the guide device can be in a simple embodiment from two 180 ° around the axis of rotation of the propellers arranged guide vanes can be formed extend radially from the axis of rotation of the propellers. It is of course also possible, more than two guide vanes provide the order in a rotationally symmetrical arrangement the axis of rotation of the propellers lie.
  • the guide vanes preferably have curved wing profiles, where it fluidically as proves to be very favorable if the curvature consists of a pre-twist and a post-twist. So that can the re-spin of the front propeller is effectively directed and by the flow around the guide vane The propulsive force generated when the front propellers re-spin recovered lost energy become.
  • FIG. 1 shows a rudder double propeller Ship propulsion with a propulsion machine arranged in the hull with vertical drive shaft 1 and drive propellers outside the hull.
  • the angular gear 3, 4 is surrounded by a housing 9 in which The output shaft 5 is rotatably supported by means of two bearings 10, 11 is.
  • This housing 9 is one of the vertical drive axis 1 concentrically surrounding and for the rudder function housing tube 9a pivotable about its longitudinal axis.
  • the underwater part of the drive system can be within one Nozzle 12 may be arranged.
  • the front propeller 6 generates a residual or Reverberation that represents lost energy.
  • a guide device 8 is provided with which directs the re-spin of the front propeller 6.
  • lost energy is recovered by the Guiding device flow around a driving force is generated.
  • the second propeller takes this criterion into account 7 preferably one different from the first propeller 6 have structural design.
  • the guide device 8 consists of two guide vanes 8a and 8b, the one guide vane 8a through the vertical drive shaft 1 surrounding housing tube 9a formed is.
  • the second guide blade 8b is located on the underside 9b of the housing surrounding the horizontal output shaft 5 9, i.e. offset by 180 ° from the first guide vane.
  • Both Guide vanes 6.7 form a structural unit with the overall housing 9.9a.
  • Figures 2 and 3 each show a cross section of the upper one Guide blade 8a or the lower guide blade 8b. Thereafter, the guide vanes 8a, 8b have curved ones Wing profiles that have a pre-twist curvature ⁇ Deflecting the flow for the second propeller 7, and a re-swirl curvature ⁇ for directing the re-swirl of the have first propeller 6.
  • the longitudinal extent L of the guide vanes 8a, 8b corresponds to as shown in Fig.4, the radius R of the Top circle 14 of the propellers 6.7.
  • FIG 5 shows a section similar to that in FIG another example of a guidance device.
  • the control device can of course also consist of more than three guide vanes.
