Definitions

  • the invention relates to a letter drive with two counter-rotating screws, the rear propeller on an inner shaft and the front propeller is attached at the head end to a hollow shaft guided concentrically to the inner shaft, the shafts being connected to a transmission, the input shaft of which is connected to a drive unit.
  • the invention has for its object to provide a generic ship propulsion that drives maintenance-friendly and low power loss merchant ships with the greatest possible saving of fuel with structurally simple means and a minimum of components for power transmission from the drive unit.
  • the thrust bearing is an integrated component of the engine or the transmission.
  • Both motors can be operated independently of one another and each act on a propeller. This applies in particular to emergency operation, so that if one drive train is damaged, the other can continue to be used without hindrance.
  • the engine speeds and the gear ratio can be set according to the desired ratio of the propellers.
  • Fuel savings of up to 10% are expected due to the precise design options for the shape of the propellers and the rotational ratio to one another, as well as the low loss of power transmission from the drive units to the bolts.
  • a coupling between the drive unit and the gearbox is not required to use only one of the CRP propellers. Stopping an engine is sufficient here.
  • the clear and uncluttered structure of the ship propulsion system also allows simple installation of standard thrust bearings for the propeller shafts.
  • FIG. 1 and 2 show the diagram of a ship's drive with the motors 11 and 12 of the drive assembly 10.
  • the motor 11 is connected via a coupling 21 to an output shaft 13, to which an inner shaft 53 is fastened, which has the rear propeller 51 at the head end Output 50 assembly.
  • the inner shaft 53 is guided through a hollow gear shaft 41 of a transmission assembly 40, a pressure bearing 31 and a brake 24 being arranged between the transmission 40 and the clutch 21.
  • the clutch 21 can be omitted.
  • a hollow shaft 54 is guided concentrically to the inner shaft 53 and has a front propeller 52 at one end and a gearwheel 41 at the other end.
  • a thrust bearing 32 is arranged between the front propeller 52 and the transmission 40.
  • a gear 42 with a smaller diameter meshes with the gear 41 and is connected via an input shaft 15 to an output shaft 14 connected to the motor 12, the shaft 14, 15 having a brake 23.
  • the output shaft 14 is connected to the motor 12 via a clutch 22 (only in FIG. 1).
  • the motor 11 is designed as a slow runner and the motor 12 as a medium speed runner.
  • the small-sized medium-speed rotor is arranged next to the propeller shafts, which leads to a very compact overall drive. It is conceivable, as is also customary in systems of this type, to connect a generator which generates the on-board current to the input-side half of the transmission. This could either work as a power take-off (PTO) or as a power take-in (PTI).
  • PTO power take-off
  • PPI power take-in
