Description
,Lagerbock an _ Kreiselmaschinen. Die Erfindung betrifft einen Lagerbock an einer Kreise maschine und ein Verfahren zur Herstellung,des Lagerbockes. Sie besteht darin, dass.der auf das Maschinengehäuse aufgesetzte, von ihm .getrennte Lagerbock einen Bodenteil und einen gegen das Gehäuse offenen Kegelmantel aufweist, wobei die Kegelaehee zur Normalen der B,o,denflä@chE um einen Winkel a geneigt ist.
Das Ver fahren zur Herstellung des Lagerbockes be- -teht darin, dass in Jen Formteil der Gussform für den Lagerbock, welcher die Aussenseite des. Lagerbockes bildet, mindestens eine fensterartige Aussparung des Kegelmantels hineingeformt wird.
Auf der Zeichnung ist die Erfindung in einem Ausführungsbeispiel sthiematisch dar gestellt. Sie zeigt einen Längsschnitt .durch eine mehrstufige Zentrifugalpumpe.
Die Lagerböcke 18 und 19 sind so aus- gebildet, d.ass sie o$me Kerne hergestellt wer den können. Der Mantel 32 ist innen und aussen als ke-gelige Fläche mit einer Achse IV ausgebildet, der um einen Winkel a gegen die Mittellinie der Welle 2, die Normale zum Loden 3,2a, nach oben geneigt ist. Die An ordnung der Fenster 26 ist ebenfalls auf die Achse IV bezogen.
Am geschlossenen Ende des Lagerbockes, dem Boden 32a, ist eine A.usnehmung 33 (Fig. 1a) von der Breite der Fenster 26, in Umfangsrichtung gesehen, vor- g <B>o</B> den daher zum esehen. Die Fenster<B>26</B> wer Beispiel für,den Lagerbock 18 mit dem Form teil geformt, der das.
linke, geschlossene Ende des Lagerbook es 18 umschliesst, während das Innere des Lagerbückes <B>18</B> zu dem Formteil gehört, der auf dem. offenen Ende des Lager bockes 18 aufsitzt. Die beiden Formteile sind in einer Ebene getrennt, die mit der rechten Endfsäch,e des. Flansches 37 übereinstimmt. Die beiden Lagerböcke 18 und 19 sind nach dem gleichen Modell geformt.
Trotzdem nun die innere Mantelfläche, 3,5 des Lagerbockes 18 ringsherum als kegelige Fläche zur Bil dung eines für das Giessen; erforderlichen Anzuges ausgebildet isst, ergibt sieh @durcb die beschriebene Form, dass die Öffnung 36 auf der linken Seite des Lagerbockes 1-8 an geordnet werden kann und -die Tropfwasser- ableitung vereinfacht werden kann. Am Flansch 37 der Lagerböcke 18, 19,
.der eine quadratische oder vieleckige Form zur Auf nahme der Zugschmauben 20 hat, sind hori zontale Fusslappen 2'1 angeordnet, die durch einen radial zum Mantel 32 angeordneten, Steg 3'8 gegen den Flansch 37 abgestützt sind.
, Bearing block on _ centrifugal machines. The invention relates to a bearing block on a circular machine and a method for producing the bearing block. It consists in that the bearing block, which is placed on the machine housing and separated from it, has a bottom part and a cone shell that is open towards the housing, the cone length being inclined to the normal to the B, o, denflä @ chE by an angle a.
The method for producing the bearing block consists in that at least one window-like recess in the cone jacket is molded into the molded part of the casting mold for the bearing block, which forms the outside of the bearing block.
In the drawing, the invention is presented in an exemplary embodiment sthiematically. It shows a longitudinal section through a multistage centrifugal pump.
The bearing blocks 18 and 19 are designed so that they can be produced without cores. The jacket 32 is designed on the inside and outside as a conical surface with an axis IV which is inclined upwards at an angle α to the center line of the shaft 2, the normal to the loden 3, 2 a. The arrangement of the window 26 is also based on the axis IV.
At the closed end of the bearing block, the bottom 32a, there is a recess 33 (FIG. 1a) the width of the window 26, seen in the circumferential direction, which can therefore be seen. The window <B> 26 </B> is an example of the bearing block 18 with the molded part that the.
left, closed end of the bearing book 18 encloses it, while the interior of the bearing bracket <B> 18 </B> belongs to the molded part that is on the. open end of the bearing block 18 is seated. The two molded parts are separated in a plane which corresponds to the right end face of the flange 37. The two bearing blocks 18 and 19 are shaped according to the same model.
Nevertheless, now the inner lateral surface, 3.5 of the bearing block 18 all around as a conical surface for the formation of one for casting; required suit is formed, see @durcb results in the form described that the opening 36 on the left side of the bearing block 1-8 can be arranged and -the drip water drainage can be simplified. On the flange 37 of the bearing blocks 18, 19,
.which has a square or polygonal shape to accommodate the pulling necks 20, horizontal foot flaps 2'1 are arranged, which are supported against the flange 37 by a web 3'8 arranged radially to the jacket 32.
