Abstract

An elongate hollow body (10) of constant cross-section is formed by extension or casting and is cut to the required length of a gear housing. The body is formed with a bore (11) and another bore (14) is subsequently formed in it. The planes containing the axes of the bores are orthogonal but the axes do not intersect. The bores overlap and communicate with each other so that a gear can be mounted in each bore for intermeshing engagement. The housing is provided with longitudinally extending cooling flanges (12) and recesses (13) for accommodating bolts. <IMAGE>

Framställningssättet kräver endast ett fåtal arbetsoperationer, och en komplett växel kan hopsättas på enkelt sätt i ett hus framställt_enligt uppfinningen. Ett sådant hus har även hög hållfasthet och precision, vilket är betydelsefullt för växelns funktion.The method of manufacture requires only a few working operations, and a complete gear can be assembled in a simple manner in a housing made according to the invention. Such a housing also has high strength and precision, which is important for the function of the gear unit.

I det följande beskrives uppfinningen närmare med hänvisning till bifogade ritning, i vilken figur 1 visar ett tvärsnitt av en långsträckt kropp som användes som utgångsmaterial vid fram- ställning av husämnen, och figur 2 och 3 visar ett längd- och ett tvärsnitt av en komplett växel monterad i ett hus fram- ställt enligt uppfinningen.In the following, the invention is described in more detail with reference to the accompanying drawing, in which Figure 1 shows a cross-section of an elongate body used as starting material in the manufacture of housing blanks, and Figures 2 and 3 show a longitudinal and a cross-section of a complete gear mounted in a housing manufactured according to the invention.

Enligt uppfinningen framställes långsträckta kroppar med konstant tvärsnittsform utefter hela sin längd och uppvisande ett aniellt hål.According to the invention, elongate bodies with a constant cross-sectional shape are produced along their entire length and having an anal hole.

Sådana profiler kan lämpligen framställas genom strängpressning Ytkvaliteten på. sålunda framställda kroppar är i allmänhet sådan, att ytterligare En lämplig tvärsnittsprofil visas i figur 1. eller stränggjutning av t.ex. aluminium. bearbetning är onödig. Eventuellt behövs en extra bearbetning av hålet 1 om det skall fungera som lagersäte med direkt kontakt med lagret.Such profiles can be conveniently produced by extruding the surface quality of. Bodies thus produced are generally such that a further suitable cross-sectional profile is shown in Figure 1. or continuous casting of e.g. aluminum. processing is unnecessary. Additional processing of the hole 1 may be required if it is to function as a bearing seat with direct contact with the bearing.

Den yttre profilen utformas lämpligen med ett antal utskjutande partier 2. som bildar längsgående åsar på kroppen, Åsarna utgör kylflänsar för växelhusen. Ned kylflänsar försedda aluminiumväxelhns har utmärkt värmeledningsförmåga, varför risken för överhettning och hopskärning av växeln är liten.The outer profile is suitably formed with a number of projecting portions 2. which form longitudinal ridges on the body. The ridges form cooling fins for the gear housings. Aluminum gearboxes fitted with cooling fins have excellent thermal conductivity, so the risk of overheating and cutting of the gearbox is small.

Det är även lämpligt att profilen utformas med ett antal utvändiga inskärningar 3 vilka bildar längsgående urtag, vars ändamål framgår nedan.It is also suitable that the profile is formed with a number of external notches 3 which form longitudinal recesses, the purpose of which is shown below.

"Från de ovan beskrivna långsträckta kropparna avskäres husämnen av önskad längd, och varje husämne förses med en urborrning, vilken korsar det axiella hålet. I figur 1 antydes denna urborr- Hålet och urborrningen har sådana dimensioner och är så belägna att ning med streckade linjer och centrumlinjen Ä. hålväggen genombrytes av urborrningen och med varandra samverkande och momentöverförande växelelement, exempelvis snäckväxeldrev, kan placeras i respektive hål och nrhorrning gå att de intar önskade inbördes lägen för samverkan. . . -..___ __:___.__._...__ v.. s I 7811426-1 Figur 2 och 3 visar en komplett växel i ett växelhus framställt I hålet 1 i huset 5 Två hålet 1 tillslutande lock 9. 10 Locken fixeras genom att enligt uppfinningen. är ett kugghjul 6 monterat i två lager 7,8. håller lagren och kugghjulet på plats. klämmas mot huset av gavlar 11,12, vilka sammenbindes av skruvförband 13,1Ä. Skruvarna 13 är placerade i de längsgående utvändiga urtagen 3 i huset 5.From the elongate bodies described above, housing blanks of the desired length are cut off, and each housing blank is provided with a bore, which crosses the axial hole. In Figure 1, this bore is indicated. the center line Ä. the hole wall is broken through by the drilling and cooperating and torque-transmitting gear elements, for example worm gears, can be placed in the respective holes and no squatting can take the desired mutual positions for cooperation. .__ v .. s I 7811426-1 Figures 2 and 3 show a complete gear in a gear housing made in the hole 1 in the housing 5 Two holes 1 closing cover 9. The covers are fixed by according to the invention a gear wheel 6 is mounted in two bearings 7,8 hold the bearings and the gear in place, are clamped against the housing by ends 11,12, which are connected by screw joints 13,1 A. The screws 13 are placed in the longitudinal outer recesses 3 in the housing 5.

I det hålet 1 korsande urtaget med centrumlinjen Ä är ett snäckdrev 15 monterat. Drevet är lagrat i två lager 16 och 17 och står i ingrepp med kugghjulet 6, där hålväggen är genombruten av urborrningen. Axeln 18 på vilken drevet 15 är vridfast monterat kan exempelvis vara ansluten till en utgående axel Urtaget är slutet av två lock 19,20, exempelvis medelst från en icke visad motor. vilka är fästade mot husets 5 sidoytor, skruvar 21, 22. Locken håller drevet 15 och lagren 16,17 på plats. ' Det med drevet 15 samverkande kugghjulet 6 är vridfast monterat på en axel 23, vilken utgör växelns utgående axel.A worm gear 15 is mounted in the hole 1 intersecting the recess with the center line Ä. The gear is mounted in two bearings 16 and 17 and is engaged with the gear 6, where the hole wall is pierced by the bore. The shaft 18 on which the gear 15 is rotatably mounted can for instance be connected to an output shaft. The recess is the end of two lids 19,20, for example by means of a motor (not shown). which are attached to the side surfaces of the housing 5, screws 21, 22. The lids hold the gear 15 and the bearings 16,17 in place. The gear 6 cooperating with the gear 15 is rotatably mounted on a shaft 23, which constitutes the output shaft of the gear.

Som framgår av ovanstående är en växel med ett hus framställt enligt uppfinningen kompakt och stabil samt lätt att montera.As can be seen from the above, a gear unit with a housing manufactured according to the invention is compact and stable and easy to assemble.

Eventuellt kan sätena för lagren 7,8 samt 16,17 utgöras av 1 hålet 1 och urtaget ínpressade bussningar, varvid husets 5 bearbetning kan förenklas. För åstadkommande av önskat läge på axeln H vid upptagning av urtaget i huset, exempelvis vid uppspän- ning av huset för borrning av urtaget, kan hålets 1 axel samt ena ändytan på huset användas som referenslinje och referensplan.Optionally, the seats for the bearings 7,8 and 16,17 can consist of 1 hole 1 and recessed bushings, whereby the machining of the housing 5 can be simplified. To achieve the desired position on the shaft H when picking up the recess in the housing, for example when tensioning the housing for drilling the recess, the shaft 1 of the hole and one end surface of the housing can be used as a reference line and reference plane.
