Definitions

  • the invention relates to a marine propulsion system having an upper housing part, a nacelle and a shaft extending between the upper housing part and the nacelle, wherein in the nacelle an underwater transmission with input and output shaft is arranged and the input shaft is connected to a drive shaft extending through the shaft , which is driven by an electric motor, wherein the electric motor is disposed within the shaft and surrounds the drive shaft.
  • Such marine propulsion systems are e.g. known from WO 2010/100 092 A2 and serve to implement by means of a propeller mounted on the output shaft, the drive energy applied to the drive shaft in driving force.
  • an electric motor arranged above the shaft in the region of the upper housing part is connected to the drive shaft and drives the output shaft and finally the elevator shaft via the underwater transmission located in the nacelle mounted propeller.
  • Such a marine propulsion usually works on the so-called diesel-electric principle, i. an internal combustion engine within the ship generates electrical energy that is delivered to the electric motor.
  • a disadvantage of the known prior art is the space required in the upper housing part arranged electric motor, which forms the highest point of the drive and has a high lubricant requirement, since both the underwater transmission enclosing nacelle and the shaft must be oil filled. This results in additional problems, such as high churning losses of gear stages running in the oil bath and poor service accessibility.
  • the object of the invention is therefore to propose a marine propulsion of the type mentioned, which circumvents the disadvantages of the prior art.
  • the invention proposes that the arranged within the shaft and the drive shaft enclosing the electric motor is connected via a reduction gear to the drive shaft, which is arranged in the upper housing part and in particular designed as a planetary gear.
  • a reduction gear By arranging such a reduction gear, it is possible to provide a slender motor of its dimensions with comparatively less torque than heretofore available, but capable of providing the necessary drive torques through the interposition of the reduction gear.
  • these can also be accommodated in a particularly slim shaft of the ship propulsion, which in turn brings fluidic advantages.
  • the reduction gear which is designed according to a proposal of the invention as a planetary gear, is easily accessible due to its arrangement in the upper housing part and thus above the electric motor for maintenance purposes and runs without significant wiping losses, in which it is forcibly lubricated via corresponding supply lines with lubricant.
  • the electric motor is integrated in a particularly space-saving manner within the shaft, ie it no longer forms the highest point of the ship propulsion and the upper housing part can be made correspondingly smaller.
  • a large installation space length is available within the shaft, so that the electric motor used can be made correspondingly long, whereby the outer diameter of the same can be reduced, without sacrificing performance.
  • Another advantage is the fact that the required oil volume in the ship's propulsion is reduced by integration of the electric motor into the shaft, since a large part of the hitherto oil-filled installation space is occupied by the electric motor.
  • the electric motor extends even beyond the shaft out into the upper housing part, which is still required for the fixation of the ship propulsion system according to the invention in the hull.
  • the ship propulsion system according to the invention may in particular be a rudder propeller, which is designed with a Versteilantrieb for rotating the nacelle and possibly also the associated shaft about a vertical axis.
  • the adjusting drive is advantageously arranged in the region of the upper housing part and forms the highest point of the ship propulsion system according to the invention, wherein the overall height of the adjusting drive can be further reduced by an angled arrangement of the adjusting motors.
  • Figure 1 is a schematic side view of a first embodiment of the ship's drive according to the invention.
  • Figure 2 shows a second embodiment of the invention
  • FIG. 3 shows the cooling of a first embodiment of the invention
  • Figure 4 shows the cooling of a second embodiment of the invention.
  • FIG. 1 shows a ship propulsion system according to a first embodiment, which is a rudder propeller which is rotatable about a vertical axis V by means of adjusting drives, which are not shown but are known per se.
  • the ship propulsion system comprises an upper housing part 10, a nacelle 12 and a shank 11 extending between the upper housing part 10 and the nacelle 12. While the upper housing part 10 is fixedly mounted in a hull, not shown here, the shaft 11 and the nacelle 12 pivotable about the axis V by means of Versteilantriebes to produce in addition to propulsion and a control pulse for the thus equipped watercraft.
  • a underwater gear 120 is received, which carries an input shaft 121 and an output shaft 122, which are arranged approximately at an angle of 90 ° to each other.
  • the horizontally extending output shaft 122 carries by way of example a propeller marked 16 at one of its ends, with which it is led out of the nacelle 12.
  • the input shaft 121 of the underwater transmission 120 is connected to a drive shaft 13 which is driven by an electric motor 14.
  • This electric motor 14 draws its energy, for example, from suitable energy storage within the ship or from an internal combustion engine to realize a diesel-electric drive.
  • the electric motor 14 is disposed within the shaft 11 and surrounds the drive shaft, wherein the electric motor 14 extends into the upper housing part 10.
  • the upper housing part 10 thus accommodates only a part of the electric motor 14 and the Versteilantrieb, while the remaining part of the electric motor 14 is disposed within the shaft.
  • the drive shaft 13 runs continuously through the electric motor 14 and is coupled to the input shaft 121 of the underwater transmission 122, wherein the electric motor 14 acts on the drive shaft 13 via an intermediate reduction gearbox, which is accommodated in the upper housing part 10 in the form of a planetary gear.
  • This planetary gear drives the electric motor 14 via a hollow shaft, within which the drive shaft 13 extends.
  • the output shaft 122 may be connected to and driven by a reduction gear 15a designed as a planetary gear.
  • a reduction gear 15a designed as a planetary gear.
  • total ratios of i> 20 can be realized.
  • a very small ring gear in underwater gear 120 can be used, which requires very favorable UD ratios.
  • the required oil volume in the ship's propulsion system is also reduced since a large part of the available installation space is already filled by the electric motor 14 in the shaft 11 and in the upper housing part 10.
  • a reduction of the oil volume can only take place to the underwater gearbox within the nacelle 12.
  • the cooling of the drive components takes place exclusively via water W flowing around below the hull S, while in the exemplary embodiment according to FIG. 4 an additional coolant circuit K is provided within the ship drive in addition to cooling by means of the water W flowing around.
