5 Opfindelsen vedrører en stander med en afstøtning af krydshovedgliderbanerne på stempel maskiner, hvorved standeren mellem bund- og dækplader har skråt forløbende ydervægge og lodrette indervægge, som er forbundet med sidevægge» der strækker sig over hele høj — 10 den, hvorved indervæggene over en del af højden af deres forsider, der vender mod hinanden, yderligere opviser gliderbaner, over hvilke normal kræfterne fra krydshovedtappen overføres til standeren* 15 Til optagelse af normalkrafterne, som ved glidebanei— ne til stempel maskiners krydshoveder - især ved dieselmotorer - skal overføres i vinkelret retning på standerne, er der hidtil anvendt på bagsiden af åndervæggene enten over gliderbanernes højde fordelte 20 vandrette tværribber eller spidsvinkelet mellem indervægsenderne og sidevæggene forløbende lodrette afstivningsvægge (CH-PS 625 603). Praksis har vist, at de ovenfor beskrevne konstruktioner er for omstændelige* 25BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a stand having a rejection of the cross-head slider webs on piston machines, wherein the stand between bottom and cover plates has obliquely extending outer walls and vertical inner walls which are connected to sidewalls extending over a whole height - the inner walls over a portion. of the height of their faces facing each other, further exhibit sliding paths over which normal forces are transferred from the cross-head pin to the stand * 15 For the absorption of the normal forces, which at the slides to the cross-heads of piston machines - especially in diesel engines - must be transmitted in a perpendicular direction. on the stands, hitherto applied to the back of the spirit walls either 20 horizontal transverse ribs distributed over the height of the slides or the apex angle between the inner wall ends and the side walls extending vertical stiffening walls (CH-PS 625 603). Practice has shown that the constructions described above are too cumbersome * 25
Yderligere tilstræbes der til en stempel maskine en byggeform, der er så kompakt som muligt; dette kræver kortest mulige cylinderafstande* Disse fremkommer som bekendt som summen af den nødvendige hovedi ejelængde, 30 den nederste stødsstangslejelængde og målene på de to krumtapvanger. For ikke at "bortforære" noget af maskin!ængden er det derfor påkrævet, at sidevæggene nederst i området ved krumtappen rykker så tæt sammen som muligt.Further, a stamping machine is sought for a construction which is as compact as possible; this requires the shortest possible cylinder distances * These are known, as the sum of the required head length, the lower bore length and the dimensions of the two crankshafts. Therefore, in order not to "waste" any of the machine, it is required that the side walls at the bottom of the crank shaft move as close together as possible.

Opgaven for opfindelsen er derfor at forenkle den samlede konstruktion af en giiderbaneafstøtning uden for det første, at en utilladelig deformation af in-5 dervæggene må tages med i købet eller for det andet, at maskinlængden må gøres større. Ifølge opfindelsen bliver denne opgave løst ved, at sidevæggene, der parvis afstøtter en indervæg, forløber skråt nedefra og opad i retning mod indervægsenderne, 10The object of the invention is, therefore, to simplify the overall construction of a guide rail support outside the first, that an unacceptable deformation of the inner walls must be included in the purchase or, secondly, that the machine length must be increased. According to the invention, this task is solved by the side walls supporting in pairs an inner wall extending inclined downwards and upwards towards the inner wall ends.
Som bekendt er normal kræfterne på gliderbanerne og dermed på indervæggene størst i nærheden af stempelbevægelsens øverste dødpunkt, Ved udformningen af sidevæggene ifølge opfindelsen opstår der i dette områ- 15 de en relativ bred kasse, som er dannet af indervæg, ydervæg og de to sidevægge, I området ved det øverste dødpunkt bliver indervæggene nær ved deres frie ender støttet af sidevæggene, så deres deformat ioner lader sig holde indenfor snævre grænser, 20 I det følgende forklares opfindelsen nærmere ved hjælp af et udførelseseksempel i sammenhæng med tegningen , 25 fig, 1 viser rent skematisk i et snit I-I fra fra fig. 2 et billede af en enkelt stander til en dieselmotor, fig, 2 gengiver i et snit II-II fra fig* 1 et 30 grundrids af to nabostandere i motoren med det derimellem liggende krydshoved, medens fig, 3 er snittet III-III fra fig, 2,As is well known, the normal forces on the sliding webs and thus on the inner walls are greatest in the vicinity of the upper dead point of the piston movement. In the design of the sidewalls according to the invention, a relatively wide box formed by the inner wall, outer wall and the two side walls is formed in this area. In the region at the top dead center, the inner walls are supported at their free ends by the side walls, so that their deformat ions can be kept within narrow limits. 20 In the following, the invention is explained in more detail by means of an exemplary embodiment in connection with the drawing, schematically in section II from FIG. Fig. 2 is a sectional view of a single stand for a diesel engine; Fig. 2 is a sectional view II-II of Fig. 1 showing a basic view of two neighboring stands in the engine with the intersecting head, while Fig. 3 is sectioned III-III of Figs. , 2,

Den i sin opbygning kendte stander, der f.eks» er opstået ved sammensvejsning af stålplader, har bundplader 2, som sammen med skråt forløbende ydervægge 3 og 5 lodrette indervægge 4 danner to trapezformede rammer.The stand known in its construction, which has arisen, for example, by welding steel plates, has bottom plates 2, which together with inclined outer walls 3 and 5 vertical inner walls 4 form two trapezoidal frames.
Disse er forbundet med hinanden med en fælles dækplade 5. Mellem ydervæggene 3 og indervæggene 4 er der trapezformede rammer udfyldt med sidevægge 6. Mellem disse forløber trækankre 7 (fig. 2), ved hjælp af 10 hvilke standeren holdes sammen med bundrammen 1 og motorens ikke viste cylinderkappe under forspænding.These are connected to each other by a common cover plate 5. Between the outer walls 3 and the inner walls 4 there are trapezoidal frames filled with side walls 6. Between these extend wooden anchors 7 (Fig. 2), by means of which the stand is held together with the bottom frame 1 and that of the motor. cylinder bar not shown under bias.
I en af en øverste og en underste halvdel bestående lejeskål 14, over hvilken der er lagt et lejedæksel 15 15, er krumtapalslen 16 lejret i bundrammen 1.In one of the upper and lower half of the bearing bowl 14, over which a bearing cover 15 15 is placed, the crank 16 is mounted in the bottom frame 1.
Som det ses af fig. 3, sammensætter den til en cylinder nødvendige maskinlængde m sig i det væsentlige af på begge sider en halv længde h/2 af hovedlejet 14, 20 længden S af det nederste leje til stødstangen 20, såvel som tykkelsen d af de to krumtapvanger 17. Som omtalt skal den pr. cylinder nødvendige motorlængde m være så lille som mulig.As seen in FIG. 3, the machine length required for a cylinder is composed essentially of on both sides a half length h / 2 of the main bearing 14, 20 the length S of the lower bearing for the thrust bar 20, as well as the thickness d of the two crankshafts 17. As referred to it must cylinder required engine length m be as small as possible.
25 I midterdelen mellem indervæggen 4 er sidevæggene 6 erstattet af en mellemvæg 8, som ved sin underside er afsluttet med en tværdrager 9. Som det ses af fig. 2, danner indervæggene 4 på standeren med deres mod hinanden vendende forsider gliderbaner for en kryds-30 hovedtaps 11 gi idesko 10, som på kendt måde er foi— bundet med stempelstangen 12 og lejret i sit lejehus 13.In the middle part between the inner wall 4, the side walls 6 are replaced by a middle wall 8, which at its underside is terminated by a transverse carrier 9. As seen in FIG. 2, the inner walls 4 of the stand with their facing faces form slides for a cross head pin 11 in idle 10, which is known in a known way with the piston rod 12 and enclosed in its bearing housing 13.
Ifølge opfindelsen har sidevæggene 6 forneden enAccording to the invention, the side walls 6 below one

4 mindre afstand fra hinanden, som netop slår til til trækankerets 7 gennemgang. De er skråtstillede og forløber opadtil fra hinanden, så at de afstøtter in-dervæggene 4 i området ved stempel bevæge!sens øverste 5 dødpunkt - i fig. 1 og 3 omtrent gengivet ved krydshovedstillingen - nær ved indervæggenes 4 frie ender. Således danner vægene 3, 4 og 6 i dette område en relativ bred og stiv "kasse", uden at motorlængden m er gjort større af den grund.4 smaller distances from each other, which just adds to the passage of the wooden anchor 7. They are inclined and extend upwardly from each other so that they support the inner walls 4 in the region of the piston movement's top 5 dead point - in fig. 1 and 3 roughly reproduced at the cross-head position - near the free ends of the inner walls 4. Thus, the walls 3, 4 and 6 in this area form a relatively wide and rigid "box" without the motor length m being increased for that reason.
10 I mellemrummet mellem sidevæggene 6 er "kassen" af sidevæg 6, ydervæg 3 og indervæg 4 forstærket med afstandsvægge 19, for at forhøje stivheden af sidevæggen med det relativt store areal i området med høj 15 belastning.In the space between the sidewalls 6, the "box" of sidewall 6, outer wall 3 and inner wall 4 is reinforced by spacing walls 19, to increase the stiffness of the sidewall with the relatively large area in the high load area.
