Definitions

  • the ship's feed is either by propeller or in in recent years due to the increase in Ship speeds, even more and more through waterjets causes.
  • the thrust resulting from these components is in the Normally through an integrated in the reduction gear Thrust bearing over the ship's foundation on the hull transfer.
  • Thrust transmission needed. Both, the electric motor and that separately installed thrust bearings are rigid with the Ship foundation connected.
  • stoppers support the thrust transmission.
  • stopper are stop surfaces in the ship's foundation on the front or on the rear contact surface of the gearbox with integrated Thrust bearing or at the separate thrust bearing.
  • the elastic positioning of the thrust bearing especially in connection with the arrangement of the elastic Elements at the height of the waveguide follow one Misalignment of the shaft line carrying the propeller opposite.
  • Such an inclination would be rigid with you the thrust bearing connected to the ship's foundation different loads on the thrust blocks of the thrust bearing on Guide the circumference of the thrust bearing.
  • These overloads are eliminated if the thrust bearing housing is set up elastically, because in In this case, the thrust bearing housing follows the movements of the Can adjust waveguide. This will cause all printing stones to Scope of the thrust bearing evenly loaded. This even Loading the thrust blocks of the thrust bearing will cause with otherwise the same conditions ultimately a smaller one Thrust bearings can be used, which is a significant Represents cost and weight advantage for the ships.
  • the elastic elements can be used in the execution of the fight disturbing vibrations the corresponding assigned frequencies adjusted so that the system is detuned.
  • the highest thrusts can be achieved, by increasing the number of elastic bearings and if necessary, this on both sides of the center of the waveguide orders.
  • Weight-related setting amounts in the elastic elements can by appropriate positioning of the elastic bearings be compensated.
  • the ship propulsion system has a motor, which is preferably a Electric motor 1 is.
  • the ship propulsion can also be from one or several diesel engines that have a gearbox Reduction of the speed is connected upstream.
  • the as Electric propulsion called ship propulsion is in particular and increasingly with naval ships because of the better ones Speed adjustment of the electric motor 1 to creep speed, preferred over the diesel engine.
  • the electricity required is generated by diesel generator sets located somewhere in the Aft ship are housed.
  • the electric motor 1 is on the elastic support 3 on the Ship foundation 7 supported.
  • the output shaft 2 of the Electric motor 1 is highly elastic Displacement clutch 4 connected to a shaft line 5.
  • the Wave line 5 is positioned by support bearing 6, which on the Ship foundation 7 are supported.
  • This waveguide 5 carries a propeller 8 at the opposite end. Depending on the required ship speed, however, can also A waterjet can be used instead of the propeller 8.
  • the baseboards 14 carrying the thrust bearing 9 are on both sides of the Thrust bearing 9 is provided parallel to the shaft line 5.
  • the Skirting boards 14 can no longer be machined on their underside, and there are also no holes, both in the thrust bearing 9 and also with the ship's foundation 7, which is used in a rigid installation of the thrust bearing 9 would be necessary.
  • In the baseboards 14 are from drilled several holes into the side, one in each Bolt 16 is inserted.
  • Each bolt 16 carries an elastic Element 17, which is part of an elastic bearing 18.
  • the elastic storage 18 consists essentially of the elastic element 17, which in the side wall of a bearing block 19 is integrated.
  • the elastic element 17 is as Rubber sleeve spring formed in a steel bushing 20th is vulcanized.
  • the serving as an elastic element 17 Rubber sleeve spring concentrically surrounds the pin 16.
  • Fig. 8 it is shown how the elastic mounting 17 individually with a corresponding offset in the construction height in the range of a few 1/11 mm in the installation height 26 (left Drawing file) that ensures that under the action of weight forces and setting amounts in rubber in the operating state later the elastic elements 18 in the desired ideal Position to the center line 27 of the waveguide 5 are (right Drawing file).
  • the ring elements 22 fit as a result of Shear loads on this change in position.
