Definitions

  • the present invention relates to a propulsion system for vessels, comprising a propeller mounted with horizontal axis on a column which extends down from the hull of the vessel, the said column enclosing a shaft for the transfer of power from a power source within the vessel to the propeller shaft.
  • Propulsion systems of this kind have previously been suggested, e.g. in the form of inboard-outboard arrangements and as so-called azimuth thrusters, where the propeller with its propeller shaft and the appurtenant column, for steering of the vessel, are turnable about a vertical axis.
  • These previously known systems are, however, unsuitable for high speed vessels, inter alia based on the requirements set with regard to weight, efficiency and complexity.
  • the propulsion system shall comprise a propeller mounted in front of the propeller shaft hub, i.e. pulling, and unturnable with respect to the column and with respect to the hull of the vessel, the column to be provided with one or more steering fins or the like for steering the vessel.
  • reference 1 denotes the bottom of a high-speed vessel, provided with a propulsion system according to this invention.
  • the propulsion system comprises an upper bevel gearing mounted in a housing 2 and connected to a motor, not shown, through a shaft 3 and to a lower bevel gearing in a housing 4 through a shaft 5 extending through a column 6.
  • the lower bevel gearing is in turn connected to a propeller 7, which may be a variable pitch propeller known per se.
  • the propeller 7 is mounted in a pulling relationship to the column 6, and the assembly consisting of propeller 7, lower gear housing 4 and column 6 is mounted unturnably with respect to the vessel below the bottom thereof.
  • the columns 6 is provided with steering means in the form of fin 8 disposed at the trailing part of the column for turning about a vertikal axis, 9.
  • the fin is shaped as part of the column cross section, which in this embodiment is drop-shaped. It lies within the scope of the invention to dispose the steering fin on the leading part of the column, or even both at the leading and at the trailing part of the column. If desired, the fin may be divided along its height, e.g. so that the column and a lower fin part extend below the lower gear housing 4.
  • Fig. 3A showing the pressure outline on the two sides of the column when the steering fin 8 is in neutral position, i.e. with zero deflection, and it appears that the pressure is equal on both sides of the column.
  • Fig. 3B does also show the pressure outline on both sides of the column, this time with a small steering fin deflection, and it appears that there is a pressure difference over the entire column including the steering fin even though the steering fin is but a major proportion of the column surface.
