Definitions
- the invention relates to a rotary joint for a drive device of a water-driven driving machine or a water-driven driving machine with the rotary joint.
- the drive device is for example a POD or a rudder propeller.
- the drive means is rotatable by means of a rotary connection on a water-bound Fahrmaschi ne.
- Examples of water-based driving machines are, cruise ships (in particular seagoing cruise ships or river cruise ships), cargo ships, cruisers, tugs, Roro ships, ferries, special ships (especially for wind parks, oil platforms, gas platforms, etc.).
- the Drehverbin tion concerns, for example, an electric rudder propeller for a seagoing fast ship, with a multi-phase electric motor, which is mounted in a gondola-like housing via a rotatable, preferably two-piece shaft under the stern of the ship and ver over ei ne slip ring assembly with electrical drive energy carful and rotatable about drive motors.
- the POD or the rudder propeller is mounted azimuthally rotatable by means of an azimuthal position.
- the azimuth bearing is for example in pod drives (also called nacelle drive) available so that the propeller of the drive as a kind of Ru and / or Manövrierorgan is used.
- pod drives also called nacelle drive
- a pod drive is known, for example, from WO 00/68073 or from EP 1 972 545 A1.
- EP 1 972 545 A1 shows a driving machine for a body of water that serves as a pod drive for a ship.
- the driving machine for one In particular, waters have an underwater housing, which is arranged on the hull of the ship, a propeller, which is arranged outside of the housing, and a Propellerwel le (ie, a drive shaft) on which the propeller sits on.
- the propeller shaft is mounted in the housing.
- the Ge housing has one or a plurality of passages through which the propeller shaft leads out of the housing ge.
- a Ge gear in the form of a planetary gear is arranged, which is coupled to the propeller shaft and a transmission housing has.
- the propeller can also be driven directly, ie without gearbox.
- a shaft seal seals the passage opening against ingress of liquid into the housing.
- the gear is in particular spaced from the shaft seal.
- the drive of the propeller shaft or the propeller via the transmission is effected by a drive motor ren adopted containing, for example, an electric motor.
- a direct drive without gear is possible.
- This electric motor is arranged in a pod drive inside the housing. If the electric motor is arranged outside the housing in the ship's hull, then it is a rudder propeller.
- a vertical shaft which is guided by the hull in the Ge housing, and arranged between the transmission and the vertical shaft crown gear bevel gear. Off guides without gear are also possible.
- the parts of the drive device may come into contact with water.
- the parts of the drive device are to be protected from water, which are located in the hull of the water-driven driving machine and / or the nacelle with the electric drive machine and / or the azimuth bearing, etc.
- a seal is to watch.
- the seal of a Drehver connection for a drive device of a water-bonded To improve driving machine.
- the improvement relates, for example, the tightness and / or improved service friendliness.
- a service-friendly seal arrangement for an azimuthal plant relates, for example, to the installation, control and / or replacement of seals.
- a solution of the problem results in a rotary connection of a drive device of a water-driven driving machine according to claim 1.
- Embodiments of the rotary connection to a drive device to a water-driven driving machine arise according to claims 2 to 13. Accordingly, a solution to the problem results in a water-driven driving machine with A rotary joint according to any one of claims 1 to 13.
- a rotary joint of a drive means of a wasserge bound driving machine has a support structure and a Rota tion structure, wherein the rotation structure is supported rotatably to Tragstruk tur, wherein the rotation structure to the support structure by means of a plurality of seals is substitutedich Tet. Due to the large number of seals, the sealing speed can be improved in a simple manner.
- the rotary joint has, in particular, bearings which allow, in particular, the azi mutale turning of a POD or rudder propeller. Due to the large number of seals in particular verhin changed that water, in which the waterborne driving machine is located, can reach the camp V. The multiple number of seals are thus provided in particular for sealing ge conditions water. For example, between the bearing and the plurality of seals also a grease seal may be provided, which prevents, for example, grease from the loading area of the bearing can escape.
- the plurality of seals is arranged concentrically to the rotation axis of the rotation structure. This allows a simple and / or compact design.
- the seals are designed as sealing rings.
- the sealing rings sit in individual chambers, the gerringe by screwing individual components, in particular Trä, are constructed. The use of carrier rings increases the assembly costs and / or the dismantling effort.
- the plurality of seals is arranged radially equidistant from the axis of rotation.
- the axis of rotation refers to the axis, which wel an azimuthal rotation allows.
- the vertical arrangement of the individual sealing rings can facilitate a compact design, but also complicate access during maintenance and repairs. This be especially true rotary joints in systems where access is possible only from above or from below.
- the plurality of seals to the rotation axis are arranged radially different be spaced apart.
- This is a service-friendly seal arrangement for an azimuthal plant. For example, work to change the seals, in particular the sealing rings, be carried out with less time and laborious processes, since in particular individual carrier rings of the seal construction no longer successively de must be mounted to possibly superimposed de exchange sealing rings can.
- the sealing rings are no longer vertically with each other, but rather obliquely offset from each other.
- the arrangement of the sealing rings can be varied so that either the static or rotatory part of the azimuth mutlagers dismantled and removed to get to the seals (gaskets).
- a plurality of seals are mutually independently interchangeable.
- the plurality of seals are arranged in a cone shape.
- the Dichtflä surface can be further simplified. In this way, the sealing surface can be designed as a cone. This variation, as well as the other variations described, can be advantageously combined.
- the plurality of seals are arranged in steps. This allows for example a better accessibility when replacing a seal, which can be done faster.
- the diameter of the plurality of seals tapers to a nacelle of the drive device.
- the diameter of the plurality of seals increases to a nacelle of the drive device.
- access to the seals from below, so gondola side, can be facilitated.
- the support structure has at least one first segment for attaching at least one first seal of the plurality of seals.
- at least parts of the support structure can be replaced together with a seal, which can shorten the time duration of an exchange.
- the support structure has at least one second segment for attachment at least at least a second seal of the plurality of seals has. This too can contribute to a shortening of the duration of a seal.
- the support structure has a plurality of receptacles for the plurality of seals, wherein the diameter of the plurality of receptacles tapers to a nacelle of the drive device. Rejuvenation improves accessibility. In case of a defect of a seal, not all de must be mounted to replace a seal.
- the support structure has a plurality of receptacles for the plurality of seals, wherein the diameter of the plurality of receptacles increases to a nacelle of the drive device. This also gives advantages in the exchange of Dichtun conditions.
- this has a lateral access.
- This lateral access may be additional Lich to a vertical access of a vertically constructed rotary connection system.
