Definitions

  • the invention relates to a support between a base plate containing an axial thrust bearing of an axially thrust-loaded piston internal combustion engine, in particular a drive machine for a ship's propeller, and the cover plate of the ship's foundation, the base plate of the machine resting on the foundation cover plate via fitting pieces made of metal or plastic and with With the help of foundation screws, each is connected to the foundation with a snug fit.
  • the object of the invention is to reduce the effort for the production of the fit-seat connections in the aforementioned type of support between the drive and the hull.
  • This object is achieved according to the invention in that the support is provided by vertically extending thrust plates which are welded onto the foundation cover plate and which are bent at an angle and are connected in their free leg to the foot of the base plate by means of fitting sleeves which receive the foundation bolts.
  • the fit is in this way laid in a fitting sleeve which is inserted into the thrust plate; the whole fit-fit connection can thus be prefabricated in the factory - both in the base plate and in the sleeve.
  • the thrust plate is bent out of the direction of the axial thrust load on its foot welded to the cover plate.
  • a resulting reduction in the elastic flexibility of the thrust plates in the vertical direction can be counteracted if the thrust plate is cut out in the region of the bends.
  • the stiffness of the thrust plates in the axial thrust direction in the area of the bent feet can be increased if the bent feet of the thrust plate are connected by a horizontal stiffening plate.
  • An axial thrust bearing 2 is installed in the base plate 1 (FIG. 1) of a piston fuel machine (not shown) for driving a ship, which absorbs the axial thrust - arrow 3 - exerted by the ship's propeller, also not shown.
  • This thrust force 3 is transmitted via a thrust ring 4 on the crankshaft 5 to the thrust bearing 2 and half of it is passed on to the side of the base plate 1 into the cover plate 6 of the ship's foundation 7.
  • the base plate 1 lies on the cover plate 6 via a plastic compound 8 (FIGS. 1-4) or individual metal fitting pieces 9 (FIGS. 5-7).
  • the metal fitting pieces 9 are made of gray cast iron, for example, and are adjusted in height so that the top of the base plate forms a horizontal surface.
  • the fitting pieces 9 are in a known manner individual, relatively small blocks in the immediate area of the foundation bolts 10.
  • a precise fit between the base plate 1 and the foundation cover plate 6 is ensured by a fitting sleeve 14, which is also penetrated by the screw 10 with play.
  • the sleeve 14 is, on the one hand, fitted into a bore 15 (FIGS. 4 and 7) of the base plate foot 12 and, on the other hand, into thrust plates 16 bent into the horizontal, one of which is arranged symmetrically to the shaft 5 on both sides of the base plate 1.
  • the thrust plate 16 is welded onto the foundation cover plate 6 with a vertical leg. With this construction it is achieved on the one hand that the fit seats 17 and 18 (FIGS. 4 and 7) in the base plate foot 12 in the thrust plate 16 can be prefabricated in the factory; on the other hand, the relatively “wide” arc of the thrust plate 16 enables elastic flexibility in the vertical direction, with which, after the plastic intermediate layer 8 has been placed, the nuts can be “re-tensioned” by tightening the nuts 11.
  • the feet 19 of the vertical legs of the thrust plates 16 welded onto the cover plate 6 are bent inwards (FIG. 3) or outwards (FIG. 6) from the shear stress direction 3.
  • the plates 16 are provided with recesses 20 in the region of the bends, as can be seen particularly from FIGS. 2 and 5.
  • a horizontal stiffening plate 21 is welded between the feet 19 of a thrust plate 16, through which the tips of the thrust loads of the thrust plates welded onto the cover plate 6 are distributed from the ends over the entire length of the weld seam 22 (FIGS. 4 and 7) will.
