Definitions

  • the invention relates to a reversing gear for a ship's drive with counter-rotating propellers, the reversing gear being coupled on the input side to a drive shaft and on the output side to a hollow shaft surrounding the drive shaft, the front propeller on the end of the hollow shaft and the rear propeller of the pair on the end of the drive shaft counter-rotating propeller is attached.
  • the object of the invention is to equip a ship or a boat with counter-rotating propellers with little technical effort and in particular also to convert from a single-propeller drive to a drive with counter-rotating propellers.
  • the reversing gear is a liquid gear housed in a shaft block, which has a pump driven by the drive shaft and a motor driving the hollow shaft.
  • a reversing gear can easily be accommodated in a shaft bracket without affecting its aerodynamic shape. Since the reversing gear is no longer arranged directly behind the drive machine in the ship's hull, but closer to the propeller, the hollow shaft and its bearings can also be made simpler. When converting a single-propeller drive, only the existing shaft bracket is removed and the shaft bracket with the reversing gear is pushed onto the drive shaft. The drive shaft propeller seat can be reused.
  • the reversing gear can be coupled to the drive shaft on the input side using simple means, in particular via a ring spring tensioning set. It goes without saying that the connecting elements of the shaft bracket are adapted to the particular shape of the ship.
  • the pump and the motor can be in separate chambers of the shaft bracket connected by flow channels
  • the reversing gear is a liquid gear with a gear pump driven by the drive shaft 3, the driven wheel 24 of which sits on the drive shaft 3 and is connected to the ring spring tensioning set 5.
  • the other wheel 25 the gear pump is mounted on both sides via bearings 26 in the shaft bracket 1.
  • the gear pump 24, 25 is housed in a separate chamber of the shaft bracket 1, which chamber is connected via flow channels 27, 28 to a further chamber in which a gear motor is housed, the driving wheel 29 of which sits on the hollow shaft 16 surrounding the drive shaft 3 or is connected in one piece with this.
  • the other wheel 30 of the gear pump is supported on both sides via bearings 31 in the associated chamber of the shaft bracket 1.
  • the drive shaft 3 is supported in a bearing 33 in a partition 32 between the two chambers, which is only penetrated by the flow channels 27, 28.
