Description
147412 i 5 Opfindelsen angår et krydshovedtapleje til stempel- maskiner, navnlig til dieselmotorer, med en mod stempelstangen vendende lejedel, en med denne lejedel fast forbundet mod plej Istangen vendende lejedel, en i lejet drejelig tap, der har en central aksialboring, som 10 står i forbindelse med en smøremiddelkilde, og som har tværboringer, der forløber på tværs af aksialboringen i tappens ene halvdel, hvilke tværboringers mundinger ved tappens overflade under i det mindste en del af plej Istangens svingningsbevægelse står i forbindelse 15 med mindst én strømningsvej, der udgår fra en lejedels lejeflade, og som udmunder i lejefladen for den mod plejlstangen vendende lejedel.This invention relates to a cross-head pin bearing for piston machines, in particular to diesel engines, with a bearing part facing the piston rod, one with this bearing part fixedly connected to the bearing Istangen, a bearing rotatable with a central axial bore which stands 10 in connection with a source of lubricant, and having transverse bores extending transverse to the axial bore in one half of the spigot, the orifices of the transverse bores at the surface of the spigot, at least part of the pivotal movement of the rod, are connected to at least one flow path starting from a bearing part bearing surface, which opens into the bearing surface for the bearing part facing the connecting rod.
Sådanne krydsh'ovedtaplejer har sædvanligt smørenoter 20 i lejefladen, gennem hvilke smøreolie indføres i lejespalten. Lejetappen har radialboringer, der udgår fra en central aksialboring. Disse radialboringer er anbragt i den ene halvdel af tappen og udmunder i lejefladen for lejedækslet.Such cross-head taper bearings usually have lubricating notes 20 in the bearing surface through which lubricating oil is introduced into the bearing slot. The bearing pin has radial bores starting from a central axial bore. These radial bores are disposed in one half of the pin and open into the bearing surface of the bearing cover.
2525
Under i det mindste en del af svingningsbevægelsen af plejIstangen står radialboringerne i forbindelse med hver sin strømningsvej, der udgår fra lejefladen på en lejedel. Derved går strømningsvejene gennem tilstrøm-30 ningsboringer til lejesadlen, hvilke boringer udmunder i noter, der findes i lejefladen for lejesadlen. Smøremiddel bliver af en pumpe pumpet gennem aksialboringen og radialboringerne til lejedækslets lejeflade og herfra gennem strømningsvejene til lejesadlens lejeflade.During at least part of the oscillation movement of the plunger rod, the radial bores are associated with each flow path starting from the bearing surface of a bearing part. In this way, the flow paths pass through influx bores to the bearing saddle, which bores open into notes found in the bearing surface of the bearing saddle. Lubricant is pumped by a pump through the axial bore and radial bores to the bearing surface of the bearing cover and thence through the flow paths to the bearing surface of the bearing saddle.
2 147412 1 På grunå af slitage kan den nedre,, bærende løbeflade for lejetappen beskadiges under driften. Por at udskyde udskiftningen af denne længst muligt skal tappen være svingbart udformet, dvs at ved en drejning på 180° skal den tidligere nedre, havarerede løbeflade 5 komme til at ligge øverst, og den ikke slidte, hidtil øverste løbeflade blive til den nedre, belastede flade.2 147412 1 In case of wear and tear, the lower bearing surface of the bearing pin can be damaged during operation. To postpone the replacement of this as far as possible, the pin must be pivotally designed, i.e. at a rotation of 180 °, the previously lower, broken running surface 5 should be placed at the top, and the non-worn, hitherto upper running surface will become the lower, loaded fleet.
Formålet med opfindelsen er at frembringe en lejetap, 10 hvor en sådan "vending" kan finde sted, og dette opnås ifølge opfindelsen ved yderligere tværboringer, der er udformet i tappens anden halvdel, og som er anbragt spejlsymmetrisk omkring et på stempelstangsaksen vinkelret diametralplan for tappen i forhold 15 til de første tværboringer.The object of the invention is to provide a bearing pin 10 where such a "reversal" can take place and this is achieved according to the invention by additional cross bores formed in the second half of the pin which are arranged symmetrically about a diametral plane perpendicular to the piston rod axis. in relation to the first transverse bores.
Alt efter om de tidligere nævnte noter, i hvilke tværboringerne gennem tappen udmunder, er anbragt i lejeskålen eller i lejesadlen, anvendes henholdsvis de 20 øvre eller nedre tværboringer til smøremiddeltilførsel.Depending on whether the previously mentioned notes, in which the transverse bores through the spigot, are placed in the bearing bowl or in the bearing saddle, the 20 upper or lower transverse bores are used respectively for lubricant supply.
Ved et havari kan tappen således hurtigt vendes, så driften atter kan genoptages.In the event of a breakdown, the pin can thus be quickly reversed so that operation can resume.
Ved at udforme lejet som omhandlet i krav 2 opnås, at 25 det bliver enkelt at fremstille tværboringerne. For at sikre mod dårlig smøring ved omvending af tappen lukkes de ikke-benyttede tværboringer ikke. For at forhindre et forøget forbrug af smøremiddel, der, især når den slidte lejeflade vender opad ved en vendt tap, 30 flyder mellem den øvre lejedel og tappen, kan man udforme lejet som omhandlet i krav 3. Herved vil kun de tværboringer, der vender mod plejIstangen, blive forsynet med smøremiddel.By forming the bearing as claimed in claim 2, it is achieved that it becomes easy to manufacture the cross bores. To prevent poor lubrication by reversing the pin, the unused cross bores are not closed. In order to prevent an increased consumption of lubricant which, especially when the worn bearing surface faces upwardly by a reversed pin, flows between the upper bearing part and the pin, the bearing as defined in claim 3 can be designed. against the care rod, be provided with lubricant.

En endetap 7 på stempelstangen 8 strækker sig gennem en diametralboring 9 i lejetappen 6 og er fast forbundet med denne ved hjælp af en gevindmøtrik 10. Lejetappen 6 har en på tværs af dens akse forløbende bo-10 ring 11, der står i forbindelse med en smørepumpe 12 og under drift modtager smøreolie fra pumpen. Lejetappen 6 har endvidere en aksialboring 13, der over et mellem diametralboringen 9 og endetappen 7 anbragt mellemrum 15 står i forbindelse med boringen 15 11 og ved sine to ender er sluttet med hver en lukke prop 14. Lejetappen 6 har endvidere fire radiale tværboringer 16, 16a, som ifølge opfindelsen forløber symmetrisk med hensyn til et horisontalt aksialplan 31 gennem tappen og fører gennem tappen 6 som diago-20 nalboringer langs en diameter. De radiale tværboringer 16, 16a udgår alle fra aksialboringen 13 og strækker sig til overfladen af den halvdel af lejetappen 6, der vender mod plejIstangen. Hver radialboring 16 udmunder i en strømningsvej i lejedelen 2, der vender 25 mod plejIstangen, idet det første element af strømningsvejen er en omkredsnot 17, der forløber i omkredsretningen for den anden lejeflade 5·An end pin 7 of the piston rod 8 extends through a diametral bore 9 of the bearing pin 6 and is firmly connected thereto by means of a threaded nut 10. The bearing pin 6 has a housing 11 extending transversely of its axis, which communicates with a lubrication pump 12 and during operation receive lubricating oil from the pump. The bearing pin 6 further has an axial bore 13 which communicates with a gap 15 between a diametral bore 9 and the end pin 7, and bears at its two ends a closing plug 14. The bearing pin 6 further has four radial cross bores 16. 16a, which according to the invention extends symmetrically with respect to a horizontal axial plane 31 through the pin and passes through the pin 6 as diagonal bores along a diameter. The radial transverse bores 16, 16a all extend from the axial bore 13 and extend to the surface of the half of the bearing pin 6 facing the plunger rod. Each radial bore 16 opens into a flow path in the bearing portion 2 facing 25 toward the groove bar, the first element of the flow path being a circumferential groove 17 extending in the circumferential direction of the second bearing surface 5.
Af fig. 2 fremgår, at hver af omkredsnoterne 17 står 30 i forbindelse med en gennemgangsboring 19 for en ' plejIstangsbolt 3 over en afstrømningsboring 20. Det fremgår, at lejedelen 1 består af to af hinanden uafhængige halvdele henholdsvis 18 og 18a. Lejedelen 2, 5 147412 1 der består af to halvdele henholdsvis 36 og 36a, der er fastgjort til den mod stempelstangen vendende ende af plejIstangen 28, indeholder foruden omkredsnoterne 17 i sin lejeflade 5 noter 21, der er udform-5 et i en lejeskål 22, og forløber i aksialretning,le-jeboringer for tappen 6 .In FIG. 2 shows that each of the circumferential grooves 17 is in contact with a through-bore 19 for a connecting rod 3 over a run-off bore 20. It can be seen that the bearing part 1 consists of two independent halves 18 and 18a, respectively. The bearing portion 2, 5 consisting of two halves 36 and 36a, respectively, attached to the end of the plunger rod 28 facing the piston rod, contains, in addition to the circumferential grooves 17 in its bearing surface 5, grooves 5 formed in a bearing bowl 22. , and in the axial direction, bearing bores for the pin 6.
Afstrømningsboringerne 20 står i forbindelse med tilstrømningskanaler 23 over yderligere dele af strøm-10 ningsvejen for smøremidlet. Denne strømningsvej omfatter gennemgangsrum 24, der findes mellem plej Istangsboltene 3 og deres gennemgangsboringer 19, og af hvilke hver enkelt står i forbindelse med en afstrømningsboring 20, samt forbindelsesboringer 25, der forløber 15 i tværretningen ved den mod stempelstangen vendende ende af plej Istangen og forbinder gennemgangsrummene 24 med de i noterne 21 udmundende tilstrømningsboringer 23.The run-off bores 20 communicate with additional inflow channels 23 over additional portions of the lubricant flow path. This flow path comprises passage space 24, which exists between the groove rod bolts 3 and their piercing bores 19, each of which communicates with a discharge bore 20, and connecting bores 25 extending 15 in the transverse direction at the end of the plunger rod and connecting the passage spaces 24 with the inflow bores opening in the grooves 21.
20 Endvidere findes der en samleboring 26, der forløber i aksialretning af lejedelen 18 og forbinder forbindelsesboringerne 25 indbyrdes, og en fra denne samleboring udgående fødeboring 27 til forsyning af plejl-stangslejet på krumtapsiden med smøremiddel, hvilken 25 boring forløber i det indre af plejlstangen 28 i retning af dettes på tegningen ikke viste leje.Further, there is an assembly bore 26 extending in the axial direction of the bearing portion 18 and connecting the connecting bores 25 to one another, and a feed bore 27 extending from this assembly bore to supply the tie rod bearing on the crank side with lubricant, the bore extending into the interior of the connecting rod 28. in the direction of its bearing not shown in the drawing.
Under drift strømmer smøreolie langs de med pile antydede strømningsveje fra smørepumpen gennem en stip-30 let antydet, bevægelig smøreledning 29, endvidere gennem en boring 11 og mellemrummet 15 ind i aksial-boringen 13 og radialboringerne 16 i lejetappen 6 i omkredsnoterne 17· Fra omkredsnoterne 17 strømmer smøreolien gennem afstrømningsboringerne 20, gennem- 6 147412 1 gangsrummene 24, forbindelsesboringerne 25 og tilstrømningsboringerne 23 til noterne 21 i lejefladen 5. Forbindelsesboringerne 25 forsyner tillige sam-leboringen 26 og fødeboringen 27, over hvilken der 5 sker en smøring af det mod krumtappen vendende plejl-stangsleje. Smøringen af den øverste lejeflade 4 be-virkes ved svingningsbevægelsen af lejet og ved for-trængingen af olien fra den mod plejIstangen vendende lejedel 2.In operation, lubricating oil along the arrows indicated flow paths from the lubrication pump through a dotted, movable lubrication line 29, further through a bore 11 and the gap 15 into the axial bore 13 and the radial bores 16 in the bearing pin 6 of the circumferential grooves 17 · From the circumferential grooves 17 17, the lubricating oil flows through the run-off bores 20, through the boreholes 24, the connecting bores 25 and the flow bores 23 to the grooves 21 in the bearing surface 5. The connecting bores 25 also provide the bore 26 and the feed bore 27, over which there is a lubrication of the crankcase. facing peg-rod bearing. The lubrication of the upper bearing surface 4 is effected by the oscillating movement of the bearing and by the displacement of the oil from the bearing part 2 facing the plunger rod.
10 I fig. 5 er der vist et snit gennem en tap 6 i større målestok; den indeholder ifølge opfindelsen yderligere radialboringer 16a i den mod stemplestangen vendende halvdel af tappen 6. Disse er anbragt spejlsym-15 metrisk med hensyn til et i forhold til stempelstangsaksen 30 vinkelret diametralplan 31 i forhold til radialboringerne 16 og er under drift åbne. Ved slid på en mod plejlstangen vendende lejeflade kan en sådan tap demonteres og drejes således, at den i be-20 gyndelsen mod stempelstangen vendende,under drift ubelastede løbebane, bliver lejret på lejefladen 5 og taget i drift som endnu ikke slidt løbeflade. De i begyndelsen passive radialboringer l6a bliver derved aktive og sikrer smøringen af lejefladen 5· 2510 In FIG. 5 shows a section through a pin 6 on a larger scale; according to the invention, it further comprises radial bores 16a in the half of the pin 6 facing the piston rod. These are arranged symmetrically with respect to a diametral plane 31 perpendicular to the piston rod axis 31 relative to the radial bores 16 and are open during operation. When worn on a bearing surface facing the connecting rod, such a pin can be removed and turned so that the running surface facing the piston rod, which is unloaded during operation, is stored on the bearing surface 5 and taken into operation as not yet worn running surface. The initially passive radial bores l6a thereby become active and ensure lubrication of the bearing surface 5 · 25
Udførelsesformen i fig. 3 og 4 adskiller sig kun fra udførelsesformen i fig. 1 og 2 ved, at tappen 32 i tilgift til den centrale aksialboring 13 har en yderligere excentrisk aksialboring 33, der er anbragt i 30 den mod plejlstangen vendende halvdel. I området for de modsatte ender udgår der hver en tværboring 34 fra aksialboringen 33, og denne tværboring forløber parallelt med et på stempelstangsaksen 30 vinkelret diametralplan 31 og udmunder i omkredsnoten 17 7 147412 1 i lejedelen 2. I den anden halvdel af tappen 32 er der yderligere en aksialboring 33a og en yderligere tværboring 3¼ anbragt spejlsymmetrisk i forhold til aksialboringen 33 og tværboringen 34 med hensyn til 5 et på stempelstangsaksen 30 vinkelret diametralplan 31. Smøreolien strømmer langs de med pile antydede strømningsveje fra smørepumpen 12 gennem smøreledningen 29 dels over boringen 11a og mellemrummet 15 videre til den centrale aksialboring 13, gennem hvilken 10 der sker en smøring af på tegningen ikke viste glide-sko, og dels over en på tegningen ikke-vist, speciel tilførsel og boringen 35 til aksialboringen 33, fra hvilken smøreolien gennem tværboringen 3^ i lejetappen 32 når ind i omkredsnoterne 17 i lejedelen 2.The embodiment of FIG. 3 and 4 differ only from the embodiment of FIG. 1 and 2 in that the pin 32 in addition to the central axial bore 13 has an additional eccentric axial bore 33 disposed in the half facing the connecting rod. In the region of the opposite ends, each transverse bore 34 exits from the axial bore 33 and this transverse bore extends parallel to a diametral plane 31 perpendicular to the piston rod axis 30 and opens in the circumferential groove 17 7 147412 1 in the bearing portion 2. In the other half of the pin 32 there is a further axial bore 33a and a further transverse bore 3¼ are arranged symmetrically with respect to the axial bore 33 and the transverse bore 34 with respect to a diametral plane 31 perpendicular to the piston rod shaft 30. the gap 15 further to the central axial bore 13, through which 10 a lubrication of sliding shoes not shown in the drawing takes place, and partly over a special supply and not shown in the drawing, and the bore 35 to the axial bore 33, from which the lubricating oil through the transverse bore 3 ^ in the bearing pin 32 reaches the circumferential grooves 17 of the bearing part 2.
15 Strømningsvejene i lejedelen 2 svarer iøvrigt i det væsentlige til udførelsesformen i fig. 1 og 2.Moreover, the flow paths in the bearing part 2 correspond substantially to the embodiment of FIG. 1 and 2.
I fig. 6 er der vist et snit gennem en tap 32 i større målestok; i den mod stempelstangen vendende halv-20 del af tappen 32 findes der til løsning af den stillede opgave en yderligere aksialboring 33a og yderligere tværboringer 34a. Disse er med hensyn til et på stempelstangsaksen 30 vinkelret diametralplan 31 ligeledes anbragt spejlsymmetrisk i forhold til aksial-25 boringerne 33 og tværboringerne 34. Derved bliver det også ved denne tap muligt at dreje den ved slid på den mod plejIstangen vendende lejeflade for at tage den endnu ikke slidte løbebane i drift.In FIG. 6, a section through a pin 32 is shown on a larger scale; an additional axial bore 33a and additional transverse bores 34a are provided in the half-portion of the pin 32 facing the piston rod. With respect to a diametral plane 31 perpendicular to the piston rod axis 30, the mirror symmetrically arranged with respect to the axial bores 33 and the transverse bores 34. This also makes it possible to rotate it by wear on the bearing surface facing the plunger rod to take the not yet worn runway in operation.
30 Opfindelsen er ikke begrænset til de beskrevne udførelseseksempler. Omkredsnoterne 17 kan således erstattes af flere enkeltboringer svarende til afstrømningsboringen 20, idet boringerne ved tappens sving- 8 147412 1 ningsbevægelse efter hinanden bringes i forbindelse med radialboringerne og med tværboringerne. Endvidere kan afstrømningsboringerne 20 være forbundet med forbindelsesboringen 25 ved hjælp af en boring eller 5 ledning, der undgår gennemgangsrummet 24.The invention is not limited to the embodiments described. Thus, the circumferential grooves 17 can be replaced by several single bores corresponding to the run-off bore 20, in that the bores are connected in succession to the radial bores and to the transverse bores by the pivotal movement of the pin. Furthermore, the run-off bores 20 can be connected to the connecting bore 25 by means of a bore or 5 conduit which avoids the passage space 24.
