Description

Oppfinnelsen angår et stativ med en støtte for krysshodeglidebanen i stempelmaskiner ifølge kravinnledningen. The invention relates to a stand with a support for the crosshead sliding path in piston machines according to the preamble.

For opptak av normalkref tene som må overføres i rett vinkel til stativet i forhold til glidebanene for stempel-maskiners krysshoder, især dieselmotorer, har det hittil vært vanlig å anordne på endeveggenes baksider, enten over glide-banenes høyde fordelte horisontale tverribber eller i spiss vinkel mellom endeveggene og sideveggene, forløpende, vertikale avstivningsvegger (CH 625 603). Praksis har vist at den foran beskrevne konstruksjon er meget omstendelig. To absorb the normal forces that must be transferred to the stand at right angles to the slideways for the crossheads of reciprocating machines, especially diesel engines, it has so far been common to arrange on the rear sides of the end walls, either horizontal transverse ribs distributed over the height of the slideways or at an acute angle between the end walls and the side walls, continuous, vertical bracing walls (CH 625 603). Practice has shown that the construction described above is very cumbersome.

Det tilstrebes for en stempelmaskin en mest mulig kompakt oppbygging, noe som krever kortest mulige sylinderav-stander. Disse fremkommer som kjent som summen av den nødven-dige hovedlagerlengde for det nedre veivstanglager og de to krumtappvangers masser. For ikke å unngå for stor maskinlengde, kreves derfor at sideveggene nederst i krumtappakselens område rykkes så tett sammen som mulig. The aim is for a piston machine to have the most compact structure possible, which requires the shortest possible cylinder distances. As is known, these appear as the sum of the necessary main bearing length for the lower crankshaft bearing and the masses of the two crank arms. In order not to avoid excessive machine length, it is therefore required that the side walls at the bottom in the area of the crankshaft are pulled together as closely as possible.

Det er den foreliggende oppfinnelses oppgave å- forenkle den totale konstruksjon av en glidebanestøtte uten å måtte godta utillatelige deformasjoner i endeveggene eller på den annen side at maskinens lengde må forlenges. Ifølge oppfinnelsen løses denne oppgave ved at sideveggene som parvis støtter en endevegg, forløper nedenfra og oppover på skrå i retning mot endeveggenes ender. It is the task of the present invention to simplify the overall construction of a sliding track support without having to accept impermissible deformations in the end walls or, on the other hand, that the length of the machine must be extended. According to the invention, this task is solved by the side walls, which in pairs support an end wall, extend from below upwards at an angle in the direction towards the ends of the end walls.

Som kjent er normalkreftene mot glidebanene og dermed mot endeveggene størst nær stempelbevegelsens øvre dødpunkt. Ved utformingen av sideveggene ifølge oppfinnelsen oppstår i dette område en relativt bred kasse som er dannet av endevegg, yttervegg og de to sidevegger. I det øvre dødpunkts i område støttes herved endeveggene nær deres frie ender av sideveggene slik at deres deformasjoner kan holdes innenfor små grenser. As is known, the normal forces against the slideways and thus against the end walls are greatest near the top dead center of the piston movement. When designing the side walls according to the invention, a relatively wide box is created in this area which is formed by the end wall, outer wall and the two side walls. In the area of the upper dead center, the end walls are supported near their free ends by the side walls so that their deformations can be kept within small limits.

I det følgende beskrives oppfinnelsen på grunnlag av en utførelse vist på tegningen hvor fig. 1 skjematisk i et snitt I-l på fig. 2 viser et riss av et enkelt stativ for en dieselmotor, fig. 2 viser i et snitt II-II på fig. 1,- et grunnriss av to ved siden av hverandre anordnede stativer for motoren, med det mellom disse liggende krysshode, og fig. In the following, the invention is described on the basis of an embodiment shown in the drawing where fig. 1 schematically in a section I-1 in fig. 2 shows a diagram of a simple stand for a diesel engine, fig. 2 shows in a section II-II in fig. 1, - a ground plan of two racks for the engine arranged next to each other, with the crosshead lying between them, and fig.

3 viser et snitt III-III på fig. 2. 3 shows a section III-III in fig. 2.

Det i sin oppbygning kjente stativ som eksempelvis er fremkommet ved sammensveising av stålplater, har bunnplater 2 som sammen med på skrå forløpende ytre vegger 3 og vertikale endevegger 4, danner to i riss trapesformede rammer. Disse er forbundet med hverandre med en felles dekkplate 5. Mellom de ytre vegger 3 og endeveggene 4 er de trapesf ormede rammer utfylt med sidevegger 6. Mellom disse forløper strekkankeret 7 (fig. 2) hvormedi stativet under forspenning holdes sammen med grunnplaten 1 dg motorens ikke viste sylindermantel. The well-known structure of the stand, which has for example been produced by welding together steel plates, has bottom plates 2 which, together with obliquely extending outer walls 3 and vertical end walls 4, form two trapezoidal frames in plan view. These are connected to each other with a common cover plate 5. Between the outer walls 3 and the end walls 4, the trapezoidal frames are filled with side walls 6. Between these runs the tension anchor 7 (fig. 2) by means of which the stand is held together with the base plate 1 under pretension and the motor's cylinder casing not shown.

Veivakselen 16 er opplagret i grunnplaten i en av en øvre og nedre halvdel bestående lagerskål 16 med et over denne anordnet lagerdeksel 15. The crankshaft 16 is stored in the base plate in a bearing cup 16 consisting of an upper and a lower half with a bearing cover 15 arranged above it.

Slik det fremgår av fig. 3 er den nødvendige maskinlengde m for en sylinder i det vesentlige sammensatt av på begge sider en halv lengde h/2 av hovedlageret 14, lengden 5 av det nedre lager 18 for veivstangen 20 samt tykkelsen d av de to krumtappvangers masser 17. Som nevnt skal den nød-vendige motorlengde m pr sylinder være minst mulig. As can be seen from fig. 3, the required machine length m for a cylinder is essentially composed of, on both sides, half the length h/2 of the main bearing 14, the length 5 of the lower bearing 18 for the connecting rod 20 and the thickness d of the two crank arm masses 17. As mentioned, the necessary engine length m per cylinder be as small as possible.

I den midtre del mellom endeveggene 4 er sideveggene 6 erstattet med en midtre vegg 8 som i undersiden er avsluttet med en tverrdrager 9. Slik det fremgår av fig. 2 danner endeveggene 4 i to stativ, med deres mot hverandre fremre sider, glidebaner for en krysshodetapps 11 glidesko 10 som på kjent måte er forbundet med stempelstangen 12 og opplagret i sitt lagerhus 13. In the middle part between the end walls 4, the side walls 6 have been replaced with a middle wall 8 which is finished on the underside with a cross beam 9. As can be seen from fig. 2, the end walls 4 in two racks, with their opposing front sides, form sliding paths for a cross-head pin 11 sliding shoe 10 which is connected in a known manner to the piston rod 12 and stored in its bearing housing 13.

Ifølge oppfinnelsen har sideveggene 6 nederst en liten avstand fra hverandre som er akkurat tilstrekkelig for gjennom-føring av strekkankre 7. Disse er skråstilt og forløper oppover fra hverandre slik de støtter endeveggene 4 i området for stempelbevegelsens øvre dødpunkt, nær endeveggenes 4 frie ender, som gjengitt tilnærmet på fig. 1 og 3 med krysshodestil-lingen. Således danner veggene 3, 4 og 6 i dette område en relativt bred og stiv "kasse", uten at motorens lengde m av denne grunn er forlenget. According to the invention, the side walls 6 have a small distance from each other at the bottom which is just sufficient for the insertion of tension anchors 7. These are inclined and extend upwards from each other so that they support the end walls 4 in the area of the top dead center of the piston movement, near the free ends of the end walls 4, which reproduced approximately in fig. 1 and 3 with the cross-head position. Thus, the walls 3, 4 and 6 in this area form a relatively wide and rigid "box", without the motor's length m being extended for this reason.

I mellomrommet mellom sideveggene 6 er "kassen" av sideveggene 6, den ytre vegg 3 og endeveggene 4 forsterket med avstandsvegger 19 for å øke stivheten for sideveggens relativt store flate i det område stor belastning oppstår. In the space between the side walls 6, the "box" of the side walls 6, the outer wall 3 and the end walls 4 is reinforced with spacer walls 19 to increase the stiffness of the side wall's relatively large surface in the area where a large load occurs.
