Definitions

  • the invention relates to a transverse thruster, in particular a bow thruster, for ships, consisting of a transverse thrust channel formed in the hull and consisting of a tunnel tube, in which a transmission housing with a propeller is arranged, with outlet openings for introducing a medium under or on the wall of the tunnel tube Pressure in the propeller area are formed.
  • transverse thrusters are known.
  • a propeller rotates in a transversal ship in the bow and / or stern and presses the suctioned water, working like an axial pump, depending on the selected direction of rotation or the wing position for variable pitch propellers to starboard or port.
  • the maneuvering of a ship at low speeds is also made easier.
  • DE-B-2 644 844 discloses a method and a device for introducing gas and water into the propeller area of a thruster.
  • This method is that gas, e.g. Air and water are injected in a uniform mixture as a directed jet.
  • gas e.g. Air and water
  • the noise reduction is to be improved largely independently of the associated reduction in performance.
  • a further arrangement for sound insulation emerges from DE-A-2 803 336, which relates to an arrangement for sound insulation of transverse beam control systems for ships, in which the tunnel tube accommodating the propeller is arranged in an transverse tube with the formation of an annular intermediate space Hull is transverse to its longitudinal axis.
  • the wall of the tunnel tube is supported on the wall of the cross tube with the interposition of elastic molded bodies.
  • Such an arrangement insulates the sound waves emanating from the tunnel tube, but the noises emanating from the transmission or from the propeller drive are not reduced by such an elastic suspension of the tunnel tube, since there is no direct elastic suspension of the transmission housing.
  • FR-A-2 252 949 provides for the introduction of compressed air into the jacket area of jacketed propellers to prevent cavitation erosion, but there is no formation of an annular compressed air supply area in the area of the two-sided openings of the jacket tube, so that no cushion of air and Water can be formed to absorb the hammer-like impacts that occur during the condensation of cavitation bubbles.
  • the invention has for its object to achieve a reduction in the hammer-like blows resulting from the sudden condensation of cavitation bubbles, which are conducted via the tunnel wall into the interior of the ship as structure-borne noise, and the mechanical noise emitted by the propeller gearbox in order to avoid the unpleasant noise that occurs when working Avoid lateral thrusters, which are particularly annoying under ships' living rooms and common rooms.
  • the cavitation noises are reduced in that the cavitation bubbles hit a softer cushion consisting of air and water when condensing.
  • the transverse thruster is designed according to a further embodiment in such a way that the transmission housing, which has a circular cross section, is held on the tunnel tube by means of an elastic suspension using elastic molded bodies, with several molded bodies in the region of the upper wall of the tunnel tube engage radially on the gear housing and the ship-side fastening of the shaped bodies to the wall surface of the vertical tube-like extension tube is carried out
  • 10 denotes the hull of a ship in which a transverse thruster 20 is arranged.
  • This transverse thruster 20 is formed by a tunnel tube 21, the wall of which is designated 22.
  • a transmission housing 24 with a propeller nacelle 25, which has a propeller 26, is arranged in the interior of the tunnel tube 21.
  • the gear housing 24 with the propeller 26 is suspended in a tubular extension 23 which is formed on the tunnel tube 21.
  • an air supply tube 31 is arranged adjacent to the two lateral openings of the tunnel tube 21, each air supply tube 31 being provided with a number of air outlet openings 30 is.
  • These air supply pipes 31 are designed as ring pipes and are arranged on the outer wall surface of the tunnel pipe 22.
  • Each of the two ring tubes 31 has a number of air outlet ports 36, the air outlet openings 30 of which lie in the area of the wall surface 22 of the tunnel tube 21, although there is also the possibility of leading these air outlet ports 36 through the wall 22 of the tunnel tube 21 to such an extent that the air outlet ports 36 come to rest with a small section in the interior of the tunnel tube 21 (FIG.
  • annular air supply pipes 31 are then connected via a further pipe 32 to a compressed air generating device indicated at 33 in FIG. 2. As shown in FIG. 1, both annular air supply pipes 31 are connected to one another at the bottom via an air connection line 34.
  • the size of the air outlet openings 30 is dimensioned such that the air can emerge in the finest distribution from this air.
  • the air outlet openings are preferably designed in the form of a nozzle, the size of the outlet opening also being able to be regulated.
  • the wall 22 of the tunnel tube 21 can be provided with an annular, groove-shaped recess, in which the air supply tube 31 is then arranged.
  • the wall 22 of the tunnel tube 21 can also be provided with a number of air outlet openings 30 which are let into the wall 22. The outside of the air outlet openings 30 is then connected to the compressed air generating device 33 via a corresponding air supply line.
  • the overall arrangement of the air outlet openings 30 is preferably such that an air stream running from the lateral openings of the tunnel tube 21 in the direction of the propeller 26 is generated, as can be seen from FIG. 1.
  • the elastic suspension 40 is carried out using shaped bodies 41 and 42, which consist of elastic plastics or other suitable elastic materials.
  • the shaped bodies 41 of the elastic suspension 40 are arranged approximately in the region of the upper wall 22 of the tunnel tube 21 of the transverse thruster 20.
  • a number of shaped bodies 41 can be radially attached to the Intervene circular gearbox housing, the ship-side attachment of the molded body 41 is then carried out on the wall surface of the tubular extension 23.
  • annular molded body 41 which has an approximately U-shaped cross-sectional profile.
  • the two drive shaft sections are designated 27a, 27b.
  • the opposite ends of the two drive shaft sections 27a, 27b are arranged at a distance from one another and carry, for example, annular disks.
  • the two ring-shaped Disks of the two drive shaft sections 27a, 27b are then connected to one another via an annular, elastic molded body 42, so that an elastic suspension is achieved which contributes significantly to the reduction of the mechanical transmission noise.
  • the gear housing 24 can also be formed in two parts and connected via an elastic molded body. Fig.
  • FIG. 4 shows a further embodiment for a bracket with elastic suspension of the gear housing, using support arms 45, which are supported on the inner wall surface of the tunnel tube 21 and are fastened to the inner wall surface of the tunnel tube.
  • the free ends of these support arms 45 have an approximately U-shaped end profile, in which a fastening pin 46 engages, which is fastened to the gear housing 24, with the interposition of elastic molded bodies 41 (FIG. 6).
  • the propeller area is surrounded from the outside with a cavity filled with sand or a similar material, as can be seen from FIG. 1.
  • the tunnel tube 21 is double-walled, specifically with the formation of an intermediate space 51.
  • the outer wall is indicated at 50.
  • An insulating material or a sand filling 52 is arranged in the intermediate space 51. All such materials, including those made of plastics, which have roughly the same sound-reducing properties as sand are used as insulation materials.
  • the intermediate space 51 provided with an insulating material or with the sand filling 52 can extend over the entire area of the tunnel tube 21; however, there is also the possibility of this double-walled design of the tunnel tube 21 to be provided only in the area of the propeller 26. In addition, this double-walled configuration of the tunnel tube 21 can extend over the entire circumference of the tunnel tube.
