Description

Die Erfindung-betrifft einen Lagerbock für eine Kreiselmaschine"and' ein Verfahren zur Herstellung des Lagerbockes. Sie besteht darin, daß der auf das Maschinengehäuse aufgesetzte, von ihm getrennte Lagerbock einen pderiteil:urj- einen gegen das Gehäuse offenen Kegelmantel aufweist, wobei die Kegelachse zur Normalen der Bodenfläche um einen Winkel a geneigt ist. Das Verfahren zur Herstellung des Lagerbockes besteht darin, daß an den Formteil der Gußform für den Lagerbock, welcher die Außenseite des Lagerbockes bildet, mindestens eine fensterartige Aussparung des Kegelmantels angeförmt wird.The invention-relates to a bearing block for a gyroscope "and ' a method of manufacturing the bearing block. It consists in the fact that the Bearing block attached to the machine housing, separated from it, a pderiteil: urj- a has the cone shell open towards the housing, the cone axis to the normal the bottom surface is inclined at an angle a. The process for making the Bearing block is that on the molded part of the mold for the bearing block, which the outside of the bearing block forms at least one window-like recess of the cone jacket is formed.

In der Zeichnung ist die Erfindung in einem Ausführungsbeispiel schematisch- dargestellt. Sie zeigt in Fig. i einen Längsschnitt durch eine mehrstufige Zentrifugalpumpe und in Fig. 2 eine Teilansicht. " Die Lagerböcke io und ia der Zentrifugalpumpe sind so ausgebildet, daß sie ohne Kerne hergestellt werden können. Der Mantel 12 ist innen und außen als kegelige Fläche mit einer Achse IV ausgebildet, die um einen Winkel a gegen die Mittellinie der Welle 2, die Normale zum Boden 13 nach oben geneigt ist. Die Anordnung der Fenster 1.4 mit den Kanten 15 ist ebenfalls auf die Achse IV bezogen. Am geschlossenen Ende des Lagerbockes, dem Boden 13, ist eine Ausnehmung 16 (Fig. 2) von der Breite der Fenster 14 in Umfangsrichtung gesehen, vorgesehen. Die Fenster 14 werden daher, z. B. für den Lagerbock io mit dem Formteil geformt, der das linke, geschlossene Ende des Lagerbockes i o umschließt, während das Innere des Lagerbockes io zu dem Formteil gehört, der auf dem offenen Ende des Lagerbockes io aufsitzt. Die beiden Formteile sind in einer Ebene getrennt, die mit der rechten Endfläche des Flansches 17 übereinstimmt. Die beiden Lagerböcke io und i i sind nach dem gleichen Modell geformt. Trotzdem nun die innere Mantelfläche ig des Lagerbockes io ringsherum als kegelige Fläche zur Bildung eines für das Gießen erforderlichen Anzuges ausgebildet ist, ergibt sich durch die beschriebene Form, daß die Öffnung 2o auf der linken Seite des Lagerbockes io angeordnet und die Tropfwasserableitung vereinfacht werden kann. Am Flansch 17 der Lagerböcke io, i i, der eine quadratische oder vieleckige Form zur Aufnahme der Zugschrauben 21 hat, sind horizontale Fußlappen 22 angeordnet, die durch einen radial zum :Mantel 12 angeordneten Steg 23 gegen den Flansch 1 7 abgestützt sind.In the drawing, the invention is shown schematically in one embodiment. shown. It shows in Fig. I a longitudinal section through a multistage centrifugal pump and in FIG. 2 a partial view. "The bearing blocks io and ia of the centrifugal pump are designed so that they can be manufactured without cores. The coat 12 is designed inside and outside as a conical surface with an axis IV, which around a Angle a against the center line of the shaft 2, the normal to the floor 13 inclined upwards is. The arrangement of the window 1.4 with the edges 15 is also on the axis IV related. At the closed end of the bearing block, the floor 13, there is a recess 16 (Fig. 2) seen from the width of the window 14 in the circumferential direction, is provided. The windows 14 are therefore, for. B. for the bearing block io formed with the molded part, which encloses the left, closed end of the bearing block i o, while the inside of the bearing block io belongs to the molded part that is on the open end of the bearing block io sit up. The two mold parts are separated in one plane, the one on the right End face of the flange 17 coincides. The two bearing blocks io and i are i shaped according to the same model. Nevertheless now the inner jacket surface ig of the bearing block io all around as a conical surface to form a surface required for casting Suit is formed, results from the shape described that the opening 2o arranged on the left side of the bearing block and the drip water drainage can be simplified. On the flange 17 of the bearing blocks io, i i, the one square or has a polygonal shape to accommodate the lag screws 21, are horizontal foot tabs 22 arranged, which by a radial to the jacket 12 arranged web 23 against the flange 1 7 are supported.
