Opfindelsen angår et krydshovedtapleje til stempelmaskiner, navnlig til dieselmotorer, og af den i krav l's indledning angivne art.BACKGROUND OF THE INVENTION The present invention relates to a cross-head bearing for piston machines, in particular for diesel engines, and of the kind specified in the preamble of claim 1.

Sådanne krydshovedtaplejer har i reglen smørenoter, der er udformet i lejefladen, og gennem hvilke smøreolie indføres i lejespalten. Ved et krydshovedtapleje af den omhandlede art, der er kendt fra beskrivelsen til schweizisk patentskrift nr. 540 442, er både smørenoterne og en optagenot, der samvirker med boringer iSuch cross-head taper bearings usually have lubricating notes formed in the bearing surface through which lubricating oil is introduced into the bearing slot.

Den foreliggende opfindelse tager sigte på at angive et ^ krydshovedtapleje af den omhandlede art, ved hvilket smørenoter og 2 145916 smøreoliefordelingskanaler muliggør en maksimal udnyttelse af lejef laden og dermed optimale specifikke trykforhold på denne flade.SUMMARY OF THE INVENTION The present invention aims to provide a cross-head taper bearing of the kind in which lubricating nuts and lubricating oil distribution channels enable maximum utilization of the bearing surface and thus optimum specific pressure conditions on this surface.

Dette opnås ifølge opfindelsen ved, at krydshovedtaplejet er udformet som angivet i krav l's kendetegnende del.This is achieved according to the invention in that the cross-head tapping bed is configured as defined in the characterizing part of claim 1.

5 Ved-denne udformning opnår man den fordel, at de strøm ningsveje, ' der tjener til optagelse af smøremidlet fra tapboringen og til fordeling af midlet, ikke bevirker nogen formindskelse af lejefladen i den højt belastede lejesadel, da der ikke findes åbne overføringsnoter i lejesadlens lejeflade. På denne måde får 10 man optimale specifikke trykforhold i den højt belastede lejedel.In this embodiment, the advantage is obtained that the flow paths which serve to take the lubricant from the tap bore and to distribute the agent do not reduce the bearing surface of the highly loaded bearing saddle, since no open transfer notes exist in the bearing saddle. bearing surface. In this way, 10 get optimum specific pressure conditions in the highly loaded bearing part.

Krydshovedtaplejet ifølge opfindelsen forklares nærmere under henvisning til tegningen, på hvilken fig. 1 viser en udførelsesform for lejet i et aksialt snit, 15 fig. 2 et snit gennem lejet i fig. 1 lange en linie II-II, fig. 3 indersiden af lejedækslet, og fig. 4 indersiden af lejesadlen.The crosshead tapping bed according to the invention is explained in more detail with reference to the drawing, in which 1 shows an embodiment of the bearing in an axial section; FIG. 2 is a section through the bed of FIG. 1 long and line II-II, fig. 3 shows the inside of the bearing cover, and FIG. 4 inside of the bearing saddle.

I figurerne er ens dele forsynet med samme henvisningstal.In the figures, similar parts are provided with the same reference numerals.

I figur 1 og 2 er et todelt lejedæksel, der nedenfor er be-20 tegnet som den første lejedel 1, fast forbundet med en lejesadel, der nedenfor er betegnet som den anden lejedel 2, ved hjælp af plejIstangsbolte 3. En første lejeflade 4, der er udformet i den første lejedel 1, danner sammen med en anden lejeflade 5, der er udformet i den anden lejedel 2, en lejeboring, i hvilken en leje-25 tap 6 er drejelig.In Figures 1 and 2, a two-piece bearing cover, designated below as the first bearing part 1, is firmly connected to a bearing saddle, which is referred to below as the second bearing part 2, by means of plunger bolts 3. A first bearing surface 4, formed in the first bearing part 1, together with a second bearing surface 5 formed in the second bearing part 2, forms a bearing bore in which a bearing pin 6 is rotatable.

En endetap 7 på en stempelstang 8 strækker sig gennem en diametralboring 9 i lejetappen 6 og er forbundet fast med denne med en gevindmøtrik 10. Lejetappen 6 har en på tværs af sin akse forløbende tværboring 11, der står i forbindelse med en smørepum-30 pe 12 og under drift modtager smøreolie fra denne pumpe. Lejetappen 6 har endvidere en aksialboring 13, der over et mellemrum 15, der findes mellem diametralboringen 9 og endetappen 7, står i forbindelse med tværboringen 11 og ved sine to ender er lukket med en lukkeprop 14 ved hver ende. Lejetappen 6 har endvidere fire radi-35 alboringer 16, der hver især udgår fra aksialboringen 13 og strækker sig hen til overfladen på lejetappen 6. Hver radialboring 16 udmunder i en til den hørende omkredsnot 17, der forløber i omkredsretningen for den første lejeflade 4. Af fig. 3 fremgår det, at den første lejedel 1 består af to af hinanden uafhængige leje- 3 1459 1 6 delhalvdele henholdsvis 18 og 18a, der hver især har to noter 17. Af fig. 2 fremgår det, at hver not 17 står i forbindelse med en gennemgangsboring for en af plejlstangsboltene 3 over en afstrømningsboring 20.An end pin 7 of a piston rod 8 extends through a diametral bore 9 of the bearing pin 6 and is connected thereto with a threaded nut 10. The bearing pin 6 has a transverse bore 11 extending across its axis which is connected to a lubricating pump 30 12 and during operation receive lubricating oil from this pump. The bearing pin 6 further has an axial bore 13 which, over a gap 15, which exists between the diametral bore 9 and the end pin 7, communicates with the transverse bore 11 and is closed at its two ends with a closing plug 14 at each end. The bearing pin 6 further has four radial bores 16, each projecting from the axial bore 13 and extending to the surface of the bearing pin 6. Each radial bore 16 opens into a circumferential groove 17 extending in the circumferential direction of the first bearing surface 4. In FIG. 3, it appears that the first bearing part 1 consists of two independent bearing half portions 18 and 18a, respectively, each having two notes 17. From fig. 2 it appears that each groove 17 communicates with a through-bore for one of the connecting rod bolts 3 over a run-off bore 20.

5 Den i den anden lejedel 2 udformede lejeflade 5 indeholder noter 21, der er udformet i lejeskålen 22 og forløber i aksial retning af lejeboringen for tappen 6. Afstrømningsboringerne 20 kommunicerer med tilstrømningskanaler 23 over yderligere dele af en strømningsvej for smøremidlet. Denne vej omfatter mellem plejl-10 stangsboltene 3 og deres gennemgangsboringer anbragte gennemgangsrum 24, der hver især står i forbindelse med en af afstrømnings-boringerne 20 og fører fra den første lejedel til den anden lejedel 2, og tværboringer 25, der forløber i tværretning af krydsho-vedlejet og forbinder gennemgangsrummene 24 med tilstrømningsbo-15 ringerne 23.5 The bearing surface 5 formed in the second bearing part 2 contains grooves 21 which are formed in the bearing bowl 22 and extend in the axial direction of the bearing bore of the pin 6. The drain bores 20 communicate with flow channels 23 over additional parts of a flow path for the lubricant. This path comprises intermediate passage spaces 24 between the connecting-10 rod bolts 3 and their passage bores, each of which communicates with one of the run-off bores 20 leading from the first bearing part to the second bearing part 2, and transverse bores 25 extending in the transverse direction of the the crosshole bed and connects the passageways 24 to the inflow bores 23.

Endvidere findes der en aksial boring 26, der forløber i aksial retning for den anden lejedel 2 og forbinder tværboringerne 25 med hinanden, og en fra aksialboringen udgående fødeboring 27, der rager ind i det indre af plejlstangen 28 i retning af et 20 nederste, ikke vist plejlstangsleje og tjener til forsyning af dette leje med smøremiddel.Furthermore, there is an axial bore 26 extending in the axial direction of the second bearing portion 2 and connecting the cross bores 25 with one another, and a feed bore 27 extending from the axial bore projecting into the interior of the connecting rod 28 in the direction of a lower 20 shown connecting rod bearing and serves to supply this bearing with lubricant.

Under drift strømmer smøreolien langs de med pile antydede strømningsveje fra smørepumpen 12 gennem en med stiplede linier vist bevægelig smøreledning 29 og videre gennem tværboringen 11 25 og mellemrummet 12 til aksialboringen 13 og gennem radialboringerne 16 i lejetappen 6 til omkredsnoterne 7 til smøring af den første lejeflade. Til forsyning af den anden lejeflade strømmer smøreolie fra noterne 7 gennem afstrømningsboringerne 20, gennemgangsrummene 24, tværboringerne 25 og tilstrømningsboringerne 23 til no-30 terne 21 i lejefladen 5. Tværboringerne 25 forsyner derved tillige aksialboringen 26 og fødeboringen 27 med olie, ved hjælp af hvilke smøring af det nederste plejlstangsleje sker.In operation, the lubricating oil flows along the indicated flow paths from the lubrication pump 12 through a dotted line movable lubrication line 29 and further through the transverse bore 11 25 and the gap 12 to the axial bore 13 and through the radial bores 16 in the bearing pin 6 to the circumferential grooves 7 for lubricating the first bearing surface. . In order to supply the second bearing surface, lubricating oil flows from the grooves 7 through the flow bores 20, the passage spaces 24, the transverse bores 25 and the flow bores 23 to the grooves 21 in the bearing surface 5. The transverse bores 25 also supply the axial bore 26 and the feed bore 27 with oil. lubrication of the lower connecting rod bearing occurs.

Opfindelsen er ikke begrænset til den beskrevne udførelsesform. Omkredsnoterne 17 kan erstattes af enkeltboringer svarende 35 til afstrømningsboringen 20, hvilke boringer ved tappens svingningsbevægelse først efter hinanden kommunicerer med radialboringerne 16. Endvidere kan strømningsvejen for smøremidlet mellem den første og den anden lejedel også omfatte en ydre ledning, der fra en tilslutning til den første lejedel fører til en tilslutning til 40 den anden lejedel.The invention is not limited to the embodiment described. The circumferential grooves 17 can be replaced by single bores corresponding to 35 of the bore 20, which bores communicate with the radial bores only one after the pivotal movement of the pin one after the other. the bearing part leads to a connection to 40 the second bearing part.
