Definitions

  • the invention relates to a device for Transfer of thrust according to the generic term of independent claim 1.
  • the Propeller or the drive shaft for the Propeller is not thrust mounted on the hull, are thrust forces from the engine, more precisely the housing of the Motors, transferred to the ship.
  • the thrust is initially from a thrust bearing in the Motor housing added and then from the motor housing to the Ship's hull, usually on the floor on which the engine is standing, transfer.
  • push wings or Stopper attached, which with the motor housing and the Ship floor is screwed and / or welded.
  • flappers or stoppers have the task of Fastening and mounting of the engine in the ship entirely to contribute generally. Beyond that, they are whole specially trained to reduce the thrust from Transfer engine housing to the hull.
  • the Push wings or stoppers are particularly strong in the longitudinal direction of the ship push and pull resistant.
  • the patent specification CH 157 404 describes a device for sound absorption for Machines like ship machines. The facility is for transferring Unsuitable thrust.
  • the fastening device according to the invention brings an improvement here, by the cumbersome back and forth transportation of the fastener omitted.
  • Such a fastening device according to the invention is characterized by the features characterized in the characterizing part of independent claim 1.
  • the dependent ones Claims relate to advantageous embodiments of the invention.
  • the fastening device according to the invention can be used without any Aids can be attached and without being heavy and difficult to use handling parts of the fastening device from cumbersome ways the engine compartment to the workshop and back to the engine compartment are transported.
  • the thrust sleeve can be one or more parts.
  • the hole does not need to be particularly precise and can easily be done with one Laser burners can be cut into the floor.
  • the exact, form-fitting The thrust sleeve or the thrust sleeves are then fitted with the Potting the soil with the sleeve or sleeves.
  • Through the Sleeve device then runs a screw, which on the one hand on the Motor housing is supported and its screw nut directly at the other end or indirectly i.e. is supported on the ship's floor by a washer.
  • the washer can be a ball cup washer on which the as Ball nut supports trained nut.
  • the screw is a so-called expansion bolt trained, i.e. it is made of steel and pre-stressed so that vibrations motor cannot loosen the screw nut.
  • Suitable casting compounds are, for example, lead, tin, Zinc pure or alloyed, brass, bronze, but also casting resins such as armored or non-reinforced casting resins that are sold under brand names such as Epocast, or Chockfast etc. are available on the market, i.e. the same material which is also used to infuse the engine.
  • the fastening device 1 is on the side of the wall 11 of the motor housing arranged.
  • the bottom 12 of the motor housing is laterally over the wall 11 extended beyond.
  • the engine is on a bed 1215 that between the engine floor 12 and the ship floor 15 is arranged.
  • a hole was made in the ship's floor 15 150 made, for example with a laser or a Burnt out gas cutting torch that is in the extension of the through the holes 130, 120 'determined cylinder.
  • This hole 150 is so large that the sleeve 16 through the bores 130 and 120 'is also guided through the hole 150 in the floor 15 fits.
  • the Sleeve 16 has a collar or collar 161 on the neck 13 is supported.
  • a screw 14 is guided through which the hole 150 protrudes through the ship floor 15.
  • the screw bolt 14 is designed as an expansion bolt, so that he has the great powers that come with the movements of the twisting and twisting hull and Ship floor can occur, compensate elastically and is not solved by vibrations.
  • a washer or washer 17 is at the bottom of the Bolt 14 over the end of the bolt 14 and the end of the Sleeve 16 put over and on the underside of the bottom 15 supported.
  • the washer 17 is in the example shown formed as a ball cup washer 17.
  • the ball nut 142 is on the ball socket 17 on the bottom of the Bottom 15 supported.
  • Fastening device 1 transmitting the thrust forces between an engine, especially a diesel engine and the bottom 15 of a ship comprises a thrust sleeve 16 which through an opening 130, 120 in the motor housing and a Opening 150 in the bottom 15 of the ship runs, which Excess, that is larger than the cross section of the Thrust sleeve 16.
  • the space 1516 between the edge of this Opening 150 in the bottom 15 of the ship and the outside of the Thrust sleeve 16 is excessively in the area of the opening 150 poured with a casting compound 19.
  • a screw 14 that runs through the thrust sleeve 16 and on one side on Motor housing 11, 13 is supported and on the other Side is supported on the floor 15 of the ship screwed under tension.
