Description
Luftgekühlter Nasehinensatz. Die Erfindung bezieht sich auf einen Ma schinensatz, bei welchem ein vorzugsweise axial durchströmtes Gebläse mit dessen An triebsmotor gleichachsig gekuppelt ist.
Nach der Erfindung sind das Gebläse und der Antriebsmotor auf einer durchlaufenden, für den Durchsatz der Kühlluft bestimmten, gemeinsamen Hohlwelle angeordnet.
Vorteilhaft ist der Maschinensatz in einem Kanal angeordnet, der durch eine Wand in zwei Räume auf den beiden Seiten des Gebläses getrennt ist, wobei die durch laufende Hohlwelle diese beiden Räume ver. bindet, um den durch Druckausgleich erzeug ten Kühlluftstrom dem Antriebsmotor zuzu leiten. Zweckmässig ist der Antriebsmotor im Raum auf der der Förderseite abgewandten Seite des Gebläses untergebracht. Hierbei kann der Kühlluftstrom nach Durchsetzen der Hohlwelle am Ende derselben durch den Deckel des Antriebsmotors umgelenkt und auf die zu kühlenden Teile des Motors zu geleitet werden.
Schliesslich kann der Übertritt der Kühl luft aus dem Antriebsmotor in das Gebläse in der Förderrichtung desselben und über zu diesem Zweck an der Gehäuseverkleidung des Antriebsmotors vorgesehene Durchtritts- öffnungen erfolgen.
Die erfindungsgemässe Ausbildung des Maschinensatzes bietet die Möglichkeit zu einem ausreichenden und kontinuierlich wir kenden Kühlkreislauf und zu einer Welle, die festigkeitsmässig zu besonders günstigen Ergebnissen führt. Ausserdem erübrigt sich die Anordnung eines besonderen Kühlgebläses für den Antriebsmotor.
In der Zeichnung ist ein Ausführungsbei spiel des Erfindungsgegenstandes dargestellt, und zwar zeigt die Figur einen aus einem mehrstufigen, axial durchströmten Gebläse mit gleichachsig gekuppeltem Elektromotor bestehenden Maschinensatz im Längsschnitt.
Der Maschinensatz 1, bei welchem ein axial durchströmtes, mehrstufiges Gebläse 2 mit dessen als Elektromotor ausgebildetem Antriebsmotor 3 gleichachsig gekuppelt ist, ist in der einen Kanal in einen Überdruck raum 4 vor dem Gebläse und einen Raum 5 hinter demselben trennenden Wand 6 so ge lagert, dass die durchlaufende, für den Durch satz der Kühlluft bestimmte gemeinsame Hohlwelle 7 die beiden Räume 4 und 5 ver bindet. Der durch den Druckausgleich er zeugte Luftstrom tritt durch die fangdüsen- artige Muffe 8 in die Hohlwelle 7 ein, durch setzt diese ihrer Länge nach und wird dem Antriebsmotor 3 zugeführt.
Die Hohlwelle 7 mündet dabei in einen haubenartigen, strö mungsgünstig durchgebildeten Deckel 9 des Antriebsmotors, durch welchen der Kühlluft strom, wie durch Pfeile verdeutlicht ist, um gelenkt und auf die zu kühlenden Teile des Antriebsmotors zugeleitet wird.
Der Kühlluftkreislauf wird schliesslich dadurch geschlossen, dass sein Luftstrom über die kiemenartigen Durchtrittsöffnungen 10 der Gehäuseverkleidung in das Gebläse 2, und zwar in der Förderrichtung desselben, eintritt.
Infolge der allseits dichten Kapselung des Antriebsmotors bietet der Maschinensatz der praktischen Verwendung die verschieden sten Möglichkeiten.
Als Antriebsmotor für das Gebläse kön nen ausser Elektromotoren auch andere Kraft maschinen Verwendung finden.
Air-cooled nose set. The invention relates to a machine set Ma, in which a preferably axially flowed through fan with its drive motor is coupled coaxially.
According to the invention, the fan and the drive motor are arranged on a continuous, common hollow shaft intended for the throughput of the cooling air.
The machine set is advantageously arranged in a channel which is separated by a wall into two rooms on both sides of the fan, the hollow shaft connecting these two rooms in order to direct the flow of cooling air generated by pressure equalization to the drive motor. The drive motor is expediently accommodated in the space on the side of the fan facing away from the conveying side. After passing through the hollow shaft at the end of the same, the cooling air flow can be deflected through the cover of the drive motor and directed towards the parts of the motor to be cooled.
Finally, the transfer of the cooling air from the drive motor into the fan can take place in its conveying direction and through openings provided for this purpose on the casing of the drive motor.
The inventive design of the machine set offers the possibility of a sufficient and continuously we kenden cooling circuit and a wave that leads to particularly favorable results in terms of strength. In addition, there is no need to arrange a special cooling fan for the drive motor.
In the drawing, a Ausführungsbei game of the subject invention is shown, namely the figure shows a machine set consisting of a multi-stage, axially flow-through fan with coaxially coupled electric motor in longitudinal section.
The machine set 1, in which an axially flowed through, multi-stage fan 2 is coaxially coupled with its drive motor 3 designed as an electric motor, is in one channel in an overpressure space 4 in front of the fan and a space 5 behind the same separating wall 6 so-ge that the continuous, for the throughput of the cooling air intended common hollow shaft 7 connects the two spaces 4 and 5 ver. The air flow generated by the pressure equalization enters the hollow shaft 7 through the nozzle-like sleeve 8, continues its length through it and is fed to the drive motor 3.
The hollow shaft 7 opens into a hood-like, flow-favorable formed cover 9 of the drive motor, through which the cooling air flow, as indicated by arrows, is directed and directed to the parts of the drive motor to be cooled.
The cooling air circuit is finally closed by the fact that its air flow enters the fan 2 via the gill-like passage openings 10 of the housing cladding, specifically in the conveying direction of the same.
As a result of the all-round sealed encapsulation of the drive motor, the machine set offers the most diverse possibilities for practical use.
In addition to electric motors, other power machines can also be used as the drive motor for the fan.
