  • Ship's propulsion arrangements wherein a propeller is fitted to a structure separate from the ship's hull are well known in the maritime field. In most cases the structure, as such, can be turned and by turning the structure the propeller stream can be directed into a desired direction. Thus, an arrangement built in this manner at the same time functions as the ship's propulsion system and as the ship's main steering device.
  • An especially favorable embodiment of such a propeller arrangement includes a separate housing structure, a so called “pod”, which in most cases is designed in a favorable shape with respect to the streaming water, in which pod the drive motor for the propeller, in most cases an electric motor, is arranged.
  • the object of the present patent application is to achieve an especially practical arrangement for the installation of one or, respectively, two or several motor units especially of modularly structure to a structure within the ship, especially but not exclusively to an arm structure extending outwards from the ship, which arm structure further favorably can be turned in relation to the ship.
  • Another object of the present invention is thus to disclose such an arrangement, which makes the installing and, respectively, the removing of the motor unit easier.
  • An object of the present invention is further to disclose such an arrangement, which renders the testing, attaching and, respectively, removing of the motor unit possible without opening the motor unit.
  • Another object of the present invention is to disclose such an arrangement, which renders a quick change of spare parts possible so that the entire motor unit can be changed as a complete module.
  • Another object of the present invention is to achieve such an arrangement, where the need for devices requiring separate maintenance or special feeding arrangements has been minimized.
  • an arrangement according to the present invention is characterized therein that said housing structure comprises, at the end opposite to said propeller, first fitting means arranged for fitting said housing structure longitudinally to corresponding second fitting means arranged at said structure connected to the ship.
  • the method according to the present invention is characterized therein that said motor unit is fitted to a fitting piece included in said structure, which structure is connected to the ship, or respectively removed therefrom, wherein said fitting or removal is effected by means of a generally longitudinal displacement in the direction of the motor's shaft so that cooperating connector plug means at said fitting piece and, respectively, at one end wall of the motor unit are essentially simultaneously brought to constitute a connection between said structure connected to the ship and said motor unit, for supplying electric power to the motor or, respectively, brought to open such connection.

  • the motor unit's 1 other fastening and installation arrangements 12 are also arranged at standard positions, i.e. preferably at one end 7 of the motor unit 1 .
  • any motor unit 1 can in an essentially identical manner be fastened either to a single-end arm structure 3 according to FIG. 5 or, respectively, to a double-end arm structure according to FIGS. 12 to 14 as described below in more detail. Due to the arrangement according to the present invention a standard-size motor unit 1 can be installed without opening the motor unit 1 , since all the measures required for attaching it, such as installing and tightening of fastening bolts, can be carried out from the direction of the lower part 6 of the arm structure 3 .

Since all the couplings required for the functioning and controlling of the motor unit 1 are simultaneously connected with one single “plug-and-play”-manoeuvre this type of coupling can be carried out practically anywhere, e.g., when testing the motor. Since there are no operations carried out inside the closed motor unit afterwards it is absolutely certain that the tested motor is in working condition.

  • FIGS. 12 to 14 disclose in more detail an alternative embodiment of the arm structure 3 according to the present invention.
  • the lower part 6 a of the arm assembly is two sided so that one motor unit 1 at any given time can be attached, at the end 7 which is opposite the propeller 5 , to respectively opposite spaced fastening surfaces 20 , 20 a .

  • the connector plug arrangement according to the present invention is implemented so that the part of insulating material 17 used as a dampproof seal for the coupling, which insulating part favorably is provided with lip seals 23 , at the same time functions as an elastic part for the coupling tongues 22 .
  • the insulation part 17 according to the connecting arrangement according to the present invention at the same time both seals and ensures the connection between the coupling tongues by pressing the coupling tongues 22 towards each other from both sides of the coupling tongue of the cooperating counterpart.
