Description
<Desc/Clms Page number 1>
Motorgebläse zur Erzeugung der lulluft für sich erwärmende Teile einer Kinomasehine.
Kinomaschinen müssen zur Abführung der durch die Projektionslampe und die umlaufenden Teile erzeugten Wärme mit einer Kühleinrichtung ausgerüstet sein. Diese kann z. B. in einem Gebläse bestehen, das durch einen Elektromotor angetrieben wird und im l'rojektorgehäuse untergebradit ist ; statt dessen kann aber auch durch in das Projektorgehäuse eingeblasene Druckluft gekühlt werden.
Gemäss der Erfindung wird zur Erzeugung der Kühlluft für sieh erwärmende Teile einer Kinomaschine ein Motorgebläse verwendet, bei dem der Antriebsmotor und das die Kühlluft für die Kinomaschine liefernde Gebläse derart zu einer baulichen Einheit vereinigt sind, dass das Gebläsegehäuse das eine Lagerschild des Motors bildet.
Ein Ausführungsbeispiel des Erfindungsgegenstandes ist in den Fig. 1 und 2 in verschiedenen Ansichten dargestellt. In Fig. 1 ist a das Gehäuse des Motorfrebläses, das an das Projektorgehäuse b auf der Motorseite angeflanscht ist. Das Gebläse befindet si also auf der dem Projektor abgewandten Seite des Motors. Auf der für Motor und Gebläse gemeinsamen Welle ", welche in dem Lagerschild und der das Gebläse gegen den Motor abschliessenden, ebenfalls lagerschildartig ausgebildeten Wand e gelagert ist, ist auf der einen Seite ein Flügelrad f zur Kühlung des Motors selbst und auf dem hinter
EMI1.1
Luft ist dieser aussen mit Kühlrippen i versehen.
Die Kühlluft wird in das Gebläse durch das Filter k (Fig. 2) eingesaugt und durch den Anschlussstutzen l wieder abgegeben.

Motor fan to generate the air for warming parts of a cinema machine.
Cinema machines must be equipped with a cooling device to dissipate the heat generated by the projection lamp and the rotating parts. This can e.g. B. consist of a fan that is driven by an electric motor and is untergebradit in the projector housing; instead, it can also be cooled by compressed air blown into the projector housing.
According to the invention, a motor fan is used to generate the cooling air for parts of a cinema machine that heat them up, in which the drive motor and the fan supplying the cooling air for the cinema machine are combined into a structural unit in such a way that the fan housing forms one end shield of the motor.
An embodiment of the subject matter of the invention is shown in FIGS. 1 and 2 in different views. In Fig. 1, a is the housing of the motor blower which is flanged to the projector housing b on the motor side. The fan is located on the side of the motor facing away from the projector. On the shaft "common to motor and fan, which is mounted in the end shield and the wall e which closes off the fan against the motor and is also designed like a end shield, there is an impeller f on one side for cooling the motor itself and on the one behind
EMI1.1
Air is provided with cooling fins i on the outside.
The cooling air is sucked into the fan through the filter k (FIG. 2) and released again through the connection piece l.
