Opfindelsen angår et krydshoved til en totakts stempelmotor med en til stempelstangen fastgjort kryds-hovedtap, som er understøttet i en lejring omfattende en med plej Istangen forbundet underpart og en med un-5 derparten forbundet overpart, hvor tappen har mindst én primær oliefordelingskanal, der kan stå i forbindelse med en ved krydshovedet monteret olietilgangsledning og en i plejlstangens længderetning forløbende oliekanal.BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a two-stroke piston engine crosshead having a pivot rod attached to the piston rod which is supported in a bearing comprising a care member and a lower part connected to the piston rod, the pin having at least one primary oil distribution channel capable of connect to an oil supply line mounted at the crosshead and a longitudinal direction of the connecting rod.

Et sådant krydshoved er velkendt fra store lang-10 somtgående forbrændingsmotorer, der anvendes som frem-drivningsanlæg i skibe eller til stationær kraftproduk-• tion, hvor den primære oliekanal i krydshovedets tap omfatter en skrå tilgangskanal, der fra en olietilgang på et tapstykke mellem en guidesko og tappens søiefia-15 de leder til en i tappens længderetning gående central boring, som i tappens centrum står i forbindelse med en lodret boring, der forløber koaksialt med stempelstangens oliekanal og udmunder nedadtil i en i tappen indfræset cirkelafsnitformet reces, der sikrer, at den 20 primære oliekanal kontinuert står i forbindelse med plejlstangens oliekanal. Når plejIstangen drejer frem og tilbage i forhold til tappen, vil plejlstangens oliekanal hele tiden stå ud for en del af recessen, men strømningstværsnittet vil variere og være mindst, når 25 plejlstangen er drejet ud i en yderstilling.Such a crosshead is well known from large slow-moving internal combustion engines used as propulsion systems in ships or for stationary power production, where the primary oil channel at the junction of the crosshead comprises a sloping inlet channel which, from an oil supply on a tap, between guide shoes and the seafoil of the pin lead to a central bore extending longitudinally, which in the center of the pin communicates with a vertical bore which extends coaxially with the oil channel of the piston rod and opens downwards in a circular section-shaped recess, which ensures that the 20 primary oil channel is continuously connected to the connecting rod's oil channel. When the connecting rod rotates back and forth relative to the pin, the connecting rod's oil channel will constantly face part of the recess, but the flow cross-section will vary and be at least when the connecting rod is turned into an outer position.

Smøre- og køleolie til selve krydshovedets lejeflade fordeles gennem aflange cirkelbueformede recesser i under- og overpartens lejeflade. Recesserne udgår fra området umiddelbart overfor recessen i tappen og kryd-30 ses af flere i lejefladen udformede aksialt forløbende fordybninger, der fordeler olien ud over hele lejefladens bredde.Lubricating and cooling oil for the crosshead bearing surface itself is distributed through elongated circular arc recesses in the bearing surface of the lower and upper part. The recesses start from the area immediately opposite the recess in the pin and are intersected by several axially extending recesses formed in the bearing surface, which distribute the oil over the entire width of the bearing surface.

Det er hensigten med opfindelsen at anvise et krydshoved med en udformning, der er enklere samtidig 35 med, at oliens fordeling til brugsstederne forbedres og lettes.It is an object of the invention to provide a crosshead having a design which is simpler while improving and facilitating the distribution of the oil to the sites of use.

DK 167075 B1 2DK 167075 B1 2

Med henblik herpå adskiller krydshovedet ifølge opfindelsen sig fra det indledningsvis nævnte krydshoved ved, at den i krydshovedtappen udformede primære oliefordelingskanal strækker sig i det væsentlige ring-5 formet rundt langs tappens periferi, og at den primære kanal over i det mindste en del af sin længde er åben udefter i tappens radiale retning.To this end, the crosshead according to the invention differs from the crosshead initially mentioned in that the primary oil distribution channel formed in the crosshead pin extends substantially annularly around the periphery of the pin and that the primary channel extends at least a portion of its length. is open outwards in the radial direction of the pin.

Som følge af at den primære oliekanal i tappen følger tappens periferi, ligger kanalen radialt lige 10 indenfor de steder på lejefladen, der skal tilføres olie, og ved at lade kanalen være udefter åben på passende steder, vil olien i kanalen stå i direkte forbindelse med de aksialt forløbende fordybninger i lejefla den. Dermed kan man udelade de cirkelbueformede reces-15 ser i under- og overpartens lejeflade, der i det kendte krydshoved var nødvendige for fordeling af olien, således at lejeskallen i underparten får stort set ens tykkelse over hele sin aksiale udstrækning og derved bliver deformationen af lejefladen under lejets tilspæn-20 ding og motorens drift mere ensartet, hvilket fremmer lejets bæreegenskaber gennem opretholdelse af en mere ensartet smøreoliefilm.Due to the fact that the primary oil channel in the pin follows the periphery of the pin, the channel is radially just 10 within the places on the bearing surface to be applied to oil, and leaving the channel open at appropriate locations, the oil in the channel will be in direct communication with the the axially extending recesses in the bearing surface thereof. This allows the circular arc recesses to be omitted in the bearing surface of the lower and upper part, which in the known crosshead was necessary for distribution of the oil, so that the bearing shell in the lower part is of substantially the same thickness over its entire axial extent and thereby becomes the deformation of the bearing surface. during the tension of the bearing and the operation of the engine more uniformly, which promotes the bearing properties of the bearing by maintaining a more uniform lubricating oil film.

Underpartens fremstilling bliver endvidere væsentlig enklere, fordi der ikke skal drejes en halvcir-25 kelbueformet reces ind i lejets bæreflade samt lejematerialet.Furthermore, the sub-part manufacture is considerably simpler, because no semi-circular arc-shaped recess is to be rotated into the bearing surface and the bearing material.

Den primære oliefordelingskanal kan hensigtsmæssigt være en ved midten af tappens søleflade beliggende rundtgående not, der har et tværsnitsareal af mindst 30 samme størrelse som gennem strømningsarealet af tilgangsledningen. En sådan not kan på fremstillingsmæssig enkel vis drejes ind i tappens søleflade, eksempelvis i forbindelse med afdrejningen af selve sølefladen.Conveniently, the primary oil distribution channel may be a circumferential groove located at the center of the spigot of the pin having a cross-sectional area of at least 30 the same size as through the flow area of the inlet line. Such a groove can be rotated in a manufacturing manner in the simple manner of the pin surface, for example in connection with the turning of the column surface itself.

Den primære kanals tværsnitsareal kan afpasses efter 35 ønske ved at gøre noten mere eller mindre dyb.The cross-sectional area of the primary channel can be adjusted to 35 desires by making the note more or less deep.

Når krydshovedet er styret i motorens tværgående retning ved at tappen har to cirkulærcylindriske ende- DK 167075 B1 3 afsnit, der er lejret i hver sin guidesko, har hvert endeafsnit fortrinsvis en ringformet sekundær oliefordelingskanal, som står i strømningsforbindelse med den primære kanal. Den sekundære kanal sikrer rigelig smø-5 ring af hele guideskoens lejeflade, og den er enkel at fremstille ved drejning ind i endeafsnittets søleflade.When the crosshead is steered in the transverse direction of the motor by the pin having two circular cylindrical end portions each housed in its guide shoe, each end section preferably has an annular secondary oil distribution channel which is in flow communication with the primary channel. The secondary channel ensures ample lubrication of the entire guide shoe bearing surface and is easy to manufacture by turning into the end section's column surface.

Yderligere fordele ved opfindelsen vil fremgå af efterfølgende nærmere beskrivelse af en foretrukken udførelsesform med henvisning til den meget skematiske 10 tegning, hvorFurther advantages of the invention will become apparent from the following detailed description of a preferred embodiment with reference to the very schematic drawing, in which

25 Det i fig. 1-4 anskueliggjorte krydshoved omfat ter en krydshovedtap 1 med et cylindrisk midterafsnit 2, der er drejeligt understøttet i en lejring omfattende en underpart 3 og en overpart 4, og to cylindriske endeafsnit 5 til lejring i ikke viste guidesko 30 for overføring af tværgående kræfter til motorens stativ.The embodiment of FIG. 1-4 illustrated cross heads comprise a cross head pin 1 with a cylindrical center section 2 pivotally supported in a bearing comprising a lower part 3 and a upper part 4, and two cylindrical end sections 5 for bearing in guide shoes 30 not shown for transfer of transverse forces to the motor stand.

Lejeunderparten 3 er udført i ét stykke med plej Istangen 6 og er på indersiden for dannelse af krydshovedets nedre lejeflade foret med lejemetal 7, 35 der sædvanligvis er istøbt på en separat lejeskal.The bearing lower part 3 is integrally formed with the groove rod 6 and is lined on the inside to form the lower bearing surface of the crosshead with bearing metal 7, 35 which is usually molded on a separate bearing shell.

Stempelstangen 8 er ved sin nederste ende udformet som en flange eller en fod 9, der ligger an mod DK 167075 B1 4 en plan flade 10 på krydshovedtappens midter af snit, hvortil stempelstangen er fastgjort ved hjælp af fire bolte 11.The piston rod 8 is formed at its lower end as a flange or a foot 9, which abuts DK 167075 B1 4 on a flat surface 10 on the middle of the crosshead pin cut to which the piston rod is secured by four bolts 11.

Lejeoverparten 4 med tilhørende lejeflade 12 5 er udført med en udsparing, der giver passage for stempelstangen og tillader, at plej Istangen 6 sammen med overparten 4 udfører en oscillerende bevægelse omkring tappen l's længdeakse.The bearing upper part 4 with associated bearing surface 125 is formed with a recess which provides passage for the piston rod and allows the groove rod 6 together with the upper part 4 to perform an oscillating movement about the longitudinal axis of the pin 1.

En primær oliefordelingskanal 13 ved midten af 10 krydshovedtappens midterafsnit 2 strækker sig ringformet rundt langs tappens periferi i et retliniet afsnit 14, der ligger som en opadtil åben not i den plane flade 10, og i et cirkulærcylindrisk afsnit 15, der ligger forsænket i forhold til tappens søleflade 15 16.A primary oil distribution channel 13 at the middle section 2 of the crosshead pin 2 extends annularly around the periphery of the pin in a rectilinear section 14, which lies as an upwardly open groove in the flat surface 10, and in a circular cylindrical section 15 which is recessed spool surface 15 16.

Fra en olietilgangskanal 17, som står i forbindelse med en ikke vist tilgangsledning, kan smøre- og køleolie strømme ned i oliefordelingskanalen 13, hvorfra olien fordeles til de enkelte brugssteder. Lejeme-20 tallet 7 står i direkte forbindelse med kanalen 17, hvilket giver særdeles god køling og smøring af lejemetallet, idet oliegennemstrømningen i kanalen er stor og olien er tilstede i rigelig mængde. Olien fordeles ud over hele bredden af lejefladen gennem flere aksialt-25 gående fordybninger 18 i lejemetallet 7.From an oil supply channel 17, which is connected to an inlet line not shown, lubricating and cooling oil can flow down into the oil distribution channel 13, from which the oil is distributed to the individual applications. The bearing number 7 is in direct communication with the duct 17, which provides very good cooling and lubrication of the bearing metal, since the oil flow in the duct is large and the oil is present in copious quantities. The oil is distributed over the entire width of the bearing surface through several axially extending recesses 18 in the bearing metal 7.

En i plejIstangen central oliekanal 19 leder til plejlstangslejet og udmunder opadtil i den primære oliekanal 13. Som følge af, at den primære kanal strækker sig langs tappens periferi, har tværsnittet af 30 den primære kanals afsnit 15 altid samme størrelse ud for oliekanalen 19, uanset den indbyrdes drejningsvinkel mellem plejIstangen 6 og tappen 1, hvilket sikrer ensartet olietilstrømning til plejlstangslejet.A central oil channel 19 in the plunger rod 19 leads to the plunger rod bearing and opens upwardly into the primary oil channel 13. As the primary channel extends along the periphery of the pin, the cross-section of the primary channel section 15 always has the same size next to the oil channel 19, regardless the mutual angle of rotation between the connecting rod 6 and the pin 1, which ensures uniform oil flow to the connecting rod bed.

Stempelstangen 8 har en central boring, hvori 35 der er indsat et i den primære oliefordelingskanal 13 udmundende rør 20, hvis nedre ende er lejret i en bøs- DK 167075 B1 5 ning 21 indskruet eller indpresset i bunden af den centrale boring. Stempelkøleolie kan fra kanalen 13 ledes til stemplet gennem røret 20 og bort fra stemplet gennem den ringformede kanal 22 uden om røret 5 20 og en afgangskanal 23 i stempelstangens fod 9.The piston rod 8 has a central bore in which a tube 20 opening into the primary oil distribution channel 13, the lower end of which is housed in a bush 21, is screwed in or pressed into the bottom of the central bore. Piston cooling oil can be passed from the duct 13 to the piston through the pipe 20 and away from the piston through the annular duct 22 around the pipe 5 20 and an outlet duct 23 in the piston rod foot 9.

Midt på hvert af tappens endeafsnit 5 er der inddrejet en ringformet sekundær kanal 24, som står i forbindelse med dels oliekanaler i den tilhørende ikke viste guidesko, dels en aksial boring 25 med en ra-10 dial boring 26 ledende til den primære kanal 13.In the middle of each end portion 5 of the pin is an annular secondary channel 24 which is connected to partly oil channels in the associated guide shoe not shown, and partly to an axial bore 25 with a radial dial bore 26 leading to the primary channel 13.

Under plej Istangens og dermed overparten 4's ovennævnte oscillerende bevægelse i forhold til kryds-hovedtappen 1, vil den ene side af bunden 27 af udsparingen i overparten drejes mellem en øvre yderstil-15 ling tæt ved foden 9 og en nedre yderstilling, hvor et størst muligt stykke af tappens søleflade er frilagt over bunden 27.During the above oscillatory movement of the rod and thus the upper part 4 relative to the cross-head pin 1, one side of the bottom 27 of the recess in the upper part will rotate between an upper outer position close to the foot 9 and a lower outer position, where a maximum possible a piece of the pillar surface is exposed over the bottom 27.

En afskærmning i form af et strimmelformet pladestykke 28, se fig. 2 og 4, tætner den primære 20 oliefordelingskanal i radial udadgående retning i det mindste i det område, der kan blive frilagt af udsparingen i overparten, idet pladestykket 28 strækker sig fra foden 9 til et punkt på tappen, der under motorens drift altid er dækket af overpartens lejeflade.A shield in the form of a strip-shaped plate piece 28, see fig. 2 and 4, the primary oil distribution channel seals in a radially outward direction at least in the area which can be exposed by the recess in the upper part, the plate piece 28 extending from the foot 9 to a point on the pin which is always covered during the engine operation. of the upper part bearing surface.

25 Med henblik på pladestykkets fastholdelse i den primære kanal er hver sidevæg af kanalens afsnit 15 udført med en reces 29, der kan have firkantet tværsnit som vist i fig. 3 eller trekantet tværsnit som vist i fig. 6, og pladestykket 28 har mindst en til 30 hver side udragende flig til indførelse i og indgreb med den tilhørende reces 29. Ved pladestykket i figr- 4 er fligene dannet af udragende tværstykker 30, som er fastgjort på pladestykkets bagside, mens pladestykket med flige 31 i fig. 5 er stanset og bukket ud af et 35 enkelt stykke tyndplade. I fig. 6 består fligene af pladestykkets skærpede randpartier 32. PladestykketFor the purpose of retaining the plate piece in the primary channel, each side wall of the section 15 of the channel is provided with a recess 29 which may have a square cross section as shown in FIG. 3 or triangular cross section as shown in FIG. 6, and the plate piece 28 has at least one to each side protruding tab for insertion into and engagement with the associated recess 29. At the plate member of FIG. 31 in FIG. 5 is punched and bent out of a single piece of thin plate. In FIG. 6, the tabs consist of the sharpened edge portions of the plate piece 32. The plate piece
