Abstract

A method for installing a radial-fan housing having a box shape stiffened by angle sections with a spiral casing arranged between the two side walls of the housing, which are joined to the lateral edges of the casing, is characterised in that said join is produced during installation with the aid of connecting dowels (1) provided spaced apart fron one another. <IMAGE>

Verfahren für die Montage eines Radial-Ventilator-GehäusesProcedure for assembling a centrifugal fan housing

Die Erfindung bezieht sich auf ein Verfahren für die Montage eines Radial-Ventilator-Gehäuses in durch Winkelprofile versteifter Kastenform mit einer zwischen den beiden Gehäuseseitenwänden angeordneter Man te 1spirale, deren Seitenkanten mit den Gehäuseseitenwänden verbunden werden.The invention relates to a method for assembling a Radial fan housing reinforced by angle profiles Box shape with one arranged between the two housing side walls Man te 1spirale, whose side edges with the housing side walls get connected.

Bisher wurde diese Verbindung mit Hilfe eines Schweißvorganges hergestellt, indem zusätzliche seitliche Abkantungen der Mantelspirale mit den Gehäuseseitenwänden durch Schweißung verbunden wurden.So far, this connection was made with the help of a welding process produced by connecting additional lateral folds of the jacket spiral to the housing side walls by welding became.

Der Erfindung liegt die Aufgabe zugrunde, die Herstellungskosten dieser Verbindung ausschlaggebend herabzusetzen.The invention is based on the object of the production costs to reduce this connection crucially.

Die Lösung, und damit die Erfindung besteht darin, daß die Verbindung zwischen den Gehäuseseitenwänden und der Mantelspirale bei der Montage mit Hilfe von im Abstand voneinander vorgesehenen Verbindungsdübeln hergestellt wird.The solution, and thus the invention, is that the connection between the housing side walls and the jacket spiral is made during assembly with the help of spaced-apart connecting dowels.

Dieses Fertigungsverfahren senkt die Herstellungskosten des Radial-Venti lator-Gehäuses durch verminderten Maschineneinsatz und Fortfall umfangreicher Vorrichtungen. Das so komplett gefertigte Gehäuse ist eine schock- und rüttelsichere Konstruktion. In weiterer Ausbildung der Erfindung werden die Verbindungsdübel von außen durch eine Bohrung in die Gehäuseseitenwand getrieben und umschließen mit ihren Spreizbeinen die Seitenkanten des Mantelspiralbleches.This manufacturing process lowers the manufacturing costs of the radial valve lator housing due to reduced use of machines and elimination of extensive devices. The completely manufactured case is a shock and vibration proof construction. In a further embodiment of the invention, the connecting dowels are driven from the outside through a hole in the housing side wall and enclose the side edges of the spiral sheet metal sheet with their splay legs.

Die Erfindung wird nachstehend anhand eines zeichnerisch dargestellen Beispieles näher erläutert. Es zeigen:The invention is illustrated below with the aid of a drawing Example explained in more detail. Show it:

Fig. 1 eine Seitenansicht eines gemäß der Erfindung montierten Radial-Ventilator-Gehäuses,Fig. 1 is a side view of an assembled according to the invention Radial fan housing,

Fig. 2 eine Draufsicht auf ein Gehäuse nach Fig. 1 und Fig. 3 die Verbindung mittels eines Blechdübels gemäß der Erfindung im Schnitt A-B.FIG. 2 shows a plan view of a housing according to FIG. 1 and FIG. 3 shows the connection by means of a sheet metal dowel according to the invention in section A-B.

Fig. 1 zeigt ein Radial-Ventilator-Gehause in Kastenform versteift durch Winkelprofile 4. Die zwischen den Gehäuseseitenwänden 3 angeordnete Mantelspirale 2 ist mit diesen durch Blechdübel 1 verbunden.Fig. 1 shows a stiffened radial fan housing in a box shape by angle profiles 4. The jacket spiral 2 arranged between the housing side walls 3 is connected to these by sheet metal dowels 1 connected.

Die stabile Gehäusekonstruktion wird aus Aluminium- oder Stahlblech im Baukastensystem gefertigt.The stable housing construction is made of aluminum or sheet steel manufactured in a modular system.

Die Verbindung der Seitenwände erfolgt durch eine Rahmenversteifung aus Winkelprofilen 4 und ergibt eine verwindungsfes te Kastenform. The side walls are connected by means of a frame stiffener from angle profiles 4 and results in a torsion-resistant box shape.

Die Montage der Mantelspirale 2 erfolgt durch maßgenaue Fixierbohrungen in den Gehäuseseitenwänden 3 mittels vorgefertigter Blechdübel 1 im Steck- und Klemmverfahren ohne eine zusätzliche Montagevorrichtung.The cladding spiral 2 is assembled using dimensionally accurate fixing bores in the housing side walls 3 by means of prefabricated Sheet metal dowels 1 in the plug-in and clamping process without an additional one Assembly device.

Die Seitenkanten des Mantelspiralbleches 2 können im Bereich eines speziellen Verbindungsdübels 1 etwas s-förmig verbogen werden, um eine bessere Verbindung zwischen Blech 2 und Dübel 1 zu erreichen .The side edges of the jacket spiral sheet 2 can be in the area of a special connecting dowels 1 can be bent into an S-shape, to achieve a better connection between sheet metal 2 and dowel 1.
