Opfindelsen vedrører en afstøtning mellem en bundplade med et 5 aksialtrykleje på en aksialtrykbelastet stempelforbrændingsmotor, især en drivmotor til en skibsskrue, og skibsfundaments dækplade, hvorved motorens bundplade over passtykker af metal eller plast ligger an på fundamentdækpladen og er forbundet med fundamentet ved hjælp af fundamentbolte med hver et pas-10 hul.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a repulsion between a base plate having an axial thrust bearing on an axial thrust-loaded piston combustion engine, in particular a propeller motor for a ship screw, and a ship's base plate, wherein each a pass-10 hole.
En kendt måde - "Germanische Lloyd-Richtlinien fiir die maschinenbauliche Fundamentierung von Motor-anlagen" sept. 1984 fig. 5 og 6 - til befæstigelse af en drivmotor på et 15 skibsskrogs fundament, består deri, ved mellemlægning af passtykker at fremstille en forbindelse mellem motorens bundplade og fundamentets dækplade ved hjælp af en pasboltforbindelse, ved hvilken en pasbolt "samvirker" med tilsvarende pashuller i bundpladen, i passtykket og i dækpladen. Denne form for for-20 bindeiser foretrækkes, når der ikke findes tilstrækkelig plads til anbringelse af såkaldte frontstoppere. Som passtykker, som motoren ligger på, anvendes derved metal- eller plastklodser af en i handelen værende støbeharpiks.A well-known way - "German Lloyd guidelines for the engine-based foundation of the motor system" Sept. 1984 fig. 5 and 6 - for attaching a drive motor to the foundation of a ship's hull, therein, by interposing the passport pieces, it is necessary to make a connection between the engine base plate and the base cover plate by means of a pass bolt connection, in which a pass bolt "cooperates" with corresponding pass holes in the base plate , in the passport and in the cover plate. This type of front linkage is preferred when there is insufficient space for so-called front stopers. As passports on which the motor is mounted, metal or plastic blocks of a commercially available casting resin are thereby used.
25 Den væsentlige ulempe ved den skildrede forbindelse består deri, at der skal udføres pashuller i dækpladen, hvilket er besværligt og bekosteligt.25 The major disadvantage of the depicted connection consists in the fact that pass holes have to be made in the cover plate, which is cumbersome and expensive.
Opgaven for opfindelsen er at formindske arbejdet og omkost-30 ningerne ved fremstillingen af pasforbindelserne ved den nævnte form for afstøtning mellem drivaggregatet og skibsskroget. Denne opgave løses ifølge opfindelsen derved, at afstøtningen sker ved hjælp af i trykretningen forløbende lodret stående på fundamentpladen fastsvejste trykplader, som er bøjet ud i en 35 vinkel og er forbundet med bundpladens fod med pasbøsninger i deres frie ben, idet pasbøsningerne optager fundamentboltene.The object of the invention is to reduce the work and costs of producing the passport connections in said form of repulsion between the drive assembly and the ship hull. This task is solved according to the invention in that the repulsion is carried out by means of vertically extending pressure plates welded to the base plate, which are bent at an angle and connected to the base of the base plate with pass bushes in their free legs, as the pass bushings take up the foundation bolts.

Pas-hullet er på denne måde forlagt til en pasbøsning, der er stukket ind i trykpladen, hele pashulforbindelsen kan derved -såvel i bundpladen som i bøsningen - præfabrikeres fabriksmæssigt.In this way, the pass-hole is placed into a pass-bush which is inserted into the pressure plate, the entire pass-hole connection can thereby be prefabricated - both in the base plate and in the bush - in the factory.

En yderligere ulempe ved de skildrede kendte afstøtninger fremkommer ved støbeharpiks-mellemlæggene, på grund af at plastpasstykkerne "sætter" sig. Denne ulempe har hidtil skullet udlignes ved hjælp af strækbolte og høje forspændinger i 10 pasboltene, hvad der ligeledes er ret bekosteligt. Ved den nye konstruktion tillader de ved deres frie ender i en vinkel udbøjede trykplader, at afstøtningen simpelthen giver efter, når plasten synker sammen; stivheden i retning af det aksiale tryk forringes ikke derved, således at den aksiale trykkraft over-15 føres problemfrit til dækpladen henholdsvis skibsfundamentet.A further disadvantage of the prior art depictions illustrated by the molding resin inserts is due to the "fit" of the plastic fitting pieces. This disadvantage has so far had to be offset by the use of tension bolts and high prestresses in the 10 pass bolts, which is also quite expensive. In the new construction, at their free ends, at angularly bent pressure plates, they allow the cast to simply give in as the plastic sinks; the stiffness in the direction of the axial pressure is not thereby degraded, so that the axial compressive force is transferred seamlessly to the cover plate and the ship foundation, respectively.
For at formindske eller undgå spændingstoppe i de på dækpladen påsvejste fødder af trykpladerne er det formålstjenligt, at trykpladernes fod, der er sammensvejst med dækpladen, er bøjet 20 ud af aksialtrykbelastningens retning. En derved fremkaldt forringelse af trykpladernes elastiske eftergivelighed i lodret retning lader sig modvirke ved, at trykpladen har udsparinger i området for udbøjningerne. Endelig kan trykpladernes stivhed i aksialtrykretning forstærkes yderligere i området 25 ved de udbøjede fødder, hvis trykpladens udbøjede fødder er forbundet med en vandret afstivningsplade.In order to reduce or avoid stress peaks in the feet welded to the cover plate by the pressure plates, it is desirable that the foot of the pressure plates welded to the cover plate be bent 20 out of the direction of the axial pressure load. A consequent deterioration of the elastic resilience of the pressure plates in the vertical direction is counteracted by the pressure plate having recesses in the region of the deflections. Finally, the stiffness of the thrust plates in the axial thrust direction can be further enhanced in the region 25 at the deflected feet if the deflected feet of the platen are connected to a horizontal stiffening plate.
I det følgende forklares opfindelsen nærmere ved hjælp af udførelseseksempler i sammenhæng med tegningen.In the following, the invention is explained in more detail by means of exemplary embodiments in the context of the drawing.

fig. 3 gengiver et snit III-III fra fig. 2; fig. 4 er snittet IV-IV fra fig. 2; og 5 fig. 5, 6 og 7 er afbildninger svarende til fig. 2-4 af en yderligere udførelsesform af den nye afstøtning.FIG. 3 shows a section III-III of FIG. 2; FIG. 4 is section IV-IV of FIG. 2; and FIG. 5, 6 and 7 are views similar to FIGS. 2-4 of a further embodiment of the new casting.
I bundpladen 1 (fig. 1) i en ikke yderligere vist stempelforbrændingsmotor til at drive et skib er der indbygget et aksi-10 alt trykleje 2, som optager den.af den ligeledes ikke viste skibspropel udøvede aksiale trykkraft - pil 3. Denne trykkraft 3 bliver derved overført gennem en trykring 4 på krumtapakslen 5 til tryklejet 2 og med halvdelen til hver side af bundpladen 1 ledet videre til dækpladen 6 i skibsfundamentet 7. Bundpla-15 den 1 ligger an på dækpladen 6 over en plastmasse 8 (fig. 1- 4), henholdsvis over enkelte metal-passtykker 9 (fig. 5-7).In the base plate 1 (Fig. 1) of a piston combustion engine not shown further, an axial thrust bearing 2 is incorporated which accommodates the axial thrust exerted by the ship propeller also not shown - arrow 3. This thrust 3 is thereby transferred through a pressure ring 4 on the crankshaft 5 to the pressure bed 2 and with half to each side of the base plate 1 passed on to the cover plate 6 in the ship foundation 7. The base plate 1 abuts on the cover plate 6 over a plastic mass 8 (Figs. 1- 4), respectively, over individual metal pass pieces 9 (Figs. 5-7).
Plastmellemlæggene 8, som består af en i handelen værende støbeharpiks til sådanne formål, strækker sig derved under hele 20 bundpladens 1 flade; metalpasstykkerne 9 er for eksempel fremstillet af grågods og således tilpasset i højden, at bundpla-deoversiden danner en vandret flade. Pas-stykkerne 9 er derved på kendt måde enkelte, relativt små klodser i området umiddelbart omkring fundamentboltene 10.The plastic spacers 8, which consists of a commercially available casting resin, thus extend over the entire surface of the bottom plate 1; for example, the metal fit pieces 9 are made of gray material and so adjusted in height that the bottom plate surface forms a horizontal surface. The pass pieces 9 are thereby known, in a known manner, to single, relatively small bricks in the area immediately around the foundation bolts 10.

Som det fremgår af fig. 4 og 7, går fundamentboltene 10, på hvis ender der er skruet møtrikker 11, gennem dækpladen 6, plastmassen 8 henholdsvis klodserne 9 og bundpladefødderne 12 i boringer 13, hvis diameter er større end boltediameteren.As shown in FIG. 4 and 7, the foundation bolts 10, at the ends of which are screwed nuts 11, pass through the cover plate 6, the plastic mass 8 and the bricks 9 and the base plate feet 12 respectively in bores 13, the diameter of which is greater than the bolt diameter.
30 Fremfor alt skal der derfor ikke mere udføres pashuller i dækpladen 6 til boltene 10.30 Above all, therefore, no more holes should be performed in the cover plate 6 to the bolts 10.
En nøjagtig tilpasning mellem bundpladen 1 og fundamentdækpladen 6 sikres ved hjælp af en pasbøsning 14, som ligeledes gen-35 nemtrænges af boltene 10 med spillerum. Bøsningen 14 er dog på den ene side tilpasset i en boring 15 (fig. 4 og 7) i bundpla-defoden 12 og på den anden side tilpasset i en trykplade 16, 4An exact fit between the base plate 1 and the foundation cover plate 6 is ensured by a fitting bushing 14 which is also penetrated by the bolts 10 with clearance. However, the bushing 14 is, on the one hand, fitted in a bore 15 (Figs. 4 and 7) in the base plate foot 12 and on the other, fitted in a pressure plate 16, 4.

som er bukket om til vandret, og hvoraf der er anbragt en på hver side af bundpladen 16 symmetrisk omkring akslen 5. Trykpladen 16 er svejset på fundamentdækpladen 6 med et lodret ben.which is folded horizontally, one of which is arranged symmetrically on each side of the base plate 16 about the shaft 5. The pressure plate 16 is welded to the base cover plate 6 with a vertical leg.

Med denne konstruktion opnås for det første, at pashullerne 17 og 18 (fig. 4 henholdsvis 7) i bundpladefoden 12 og i trykpladen 16 kan præfabrikeres fabriksmæssigt, for det andet muliggør den relativ "brede" bue på trykpladen 16 en elastisk ef-10 tergivelighed i lodret retning, med hvilken en "efterspænding" af afstøtningen er mulig ved at spænde møtrikkerne 11, efter at plastmellemlægget 8 har "sat" sig.Firstly, with this construction, the pass holes 17 and 18 (Figs. 4 and 7, respectively) in the base plate foot 12 and in the pressure plate 16 can be prefabricated in the factory, secondly, the relatively "wide" arc on the pressure plate 16 allows an elastic effect. in the vertical direction with which a "retightening" of the support is possible by tightening the nuts 11 after the plastic spacer 8 has "sat".
For at mildne trykspændingstoppe er fødderne 19 på trykplader-15 nes 16 lodrette ben, som er svejset på dækpladen 6, bøjet indad (fig. 3) eller udad (fig. 6) fra trykspændingsretningen 3.To mitigate compressive stress peaks, the feet 19 of the vertical legs of the pressure plate 16 welded to the cover plate 6 are bent inwardly (Fig. 3) or outwardly (Fig. 6) from the compressive direction 3.
For at denne ombøjning af trykpladerne 16 skal begrænse deres elastiske eftergivelighed i lodret retning så lidt som muligt, er stykkerne 16 forsynet med udsparinger 20 i udbøj ningsoiiirå-20 derne, således som det især fremgår af fig. 2 og 5.In order for this bending of the pressure plates 16 to limit their elastic resilience in the vertical direction as little as possible, the pieces 16 are provided with recesses 20 in the deflection zones 20, as can be seen in particular in FIG. 2 and 5.
Endelig er der ved det første udførelseseksempel imellem fødderne 19 på en trykplade 16 indsvejset en vandret afstivningsplade 21, gennem hvilken toppene af trykbelastningerne på de 25 på dækpladen 6 påsvejste trykplader fordeles fra enderne og over hele længden af svejsesømmen 22 (fig. 4 og 7).Finally, in the first embodiment, between the feet 19 of a printing plate 16, a horizontal stiffening plate 21 is welded through which the peaks of the pressure loads on the 25 welded plate plates welded to the cover plate 6 are distributed from the ends and over the entire length of the welding seam 22 (Figs. 4 and 7). .
