  • the invention relates to a nacelle drive for a floating device according to claim 1.
  • the EP 1 972 545 A1 discloses a nacelle propulsion for a ship with an underwater housing circumscribed by the water, which is arranged at the bottom on a hull of a ship, a propeller, which is arranged outside of the housing, and a propeller shaft, on which the propeller sits.

  • Each module is composed of a propeller, a propeller shaft, an electric motor, two support bearings and a thrust bearing or a combination thereof with the associated foundations.
  • Such gondola drives serve as a propulsion drive for larger floating equipment, such as e.g. Ships and offshore platforms, and are often referred to as pod drives or rudder propellers. They usually have a capacity of 0.5 to 10 MW.

  • the nacelle drive thus consists of separate, preferably standardized, modules that are each manufactured separately at different production sites, tested for their functionality and then assembled at a turn different location, eg on site at a shipyard, to a nacelle drive. It is essential here that the modules also each already at least a part of the underwater housing of the nacelle drive include. As a result, the assembly of the nacelle drive can be particularly simple and inexpensive.
  • the drive module and the transmission module can thereby form the basic components of a modular system for a nacelle drive, in which, depending on power requirements and other characteristic requirements of the nacelle drive (eg efficiency, hydrodynamic properties) one or two drive modules combined with one or two transmission modules combined to form a nacelle drive can be.
  • an adaptation of the rotational speed of the shaft or of a motor driving the shaft to a desired rotational speed of the propeller can be effected in a simple manner via the transmission.

However, it is also possible that the electric motor is arranged in the interior of the floating device, and drives the shaft via a shaft extending through the vertical shaft and an angle gear, which is arranged in the drive module housing.
