Description

Klein-Gebläse mit Elektromotor in zylindrischem Gehäuse, insbesondere zum Einbau in Koffer-Harmonien Die Erfindung betrifft Klein-Gebläse mit Elektromotor in zylindrischem Gehäuse, insbesondere zum Einbau in Koffer-Harmonien.Small blower with an electric motor in a cylindrical housing, in particular for installation in case harmonies The invention relates to small blowers with an electric motor in a cylindrical housing, especially for installation in case harmonies.

Diese Gebläse müssen klein, leicht und leise sein. Bei den bekannten Gebläsen dieser Art ist das Gehäuse entweder aus Blech gezogen und daher schwer und in der Herstellung teuer, oder es ist aus hartem Kunststoff gepreßt und daher infolge der Sprödigkeit des Kunststoffes stoßempfindlich; und beide Gehäuse neigen infolge der Härte ihres Werkstoffes dazu, zu dröhnen. Gehalten wird ihr Motor im Gehäuse durch starre Schrauben oder durch Schaumgammiklötze; nachteilig ist bei jenen, daß sie die Gefahr des Dröhnens verstärken, und bei diesen, daß sie ziemlich breit sein müssen und daher den Luftweg verengen und größere Gehäuse erfordern.These fans have to be small, light and quiet. With the known For fans of this type, the housing is either made of sheet metal and is therefore heavy and expensive to manufacture, or it is molded from hard plastic and therefore sensitive to shock due to the brittleness of the plastic; and both housings tilt due to the hardness of their material to boom. Your engine is held in the Housing by rigid screws or by foam gamma blocks; is disadvantageous at those that they increase the danger of roaring, and those that they are quite must be wide and therefore narrow the airway and require larger housings.

Die Erfindung sieht statt dessen vor, daß das Gehäuse aus weichelastischem Kunststoff besteht und der Motor darin nahe seinem einen Ende mittels zweier radialer Schraubbolzen, die das Gehäuse durchdringen und im Gewinde des Motors eingeschraubt sind, axial fixiert und zentriert und nahe seinem anderen Ende mittels zweier Stützen, die am Gehäuse befestigt sind, zentriert ist, wobei das Gehäuse oval gespannt ist.The invention provides instead that the housing made of soft elastic There is plastic and the motor in it near its one end by means of two radial Screw bolts that penetrate the housing and screw into the thread of the motor are axially fixed and centered and near its other end by means of two supports, which are attached to the housing, is centered, the housing being stretched oval.

Der weiche Werkstoff des Gehäuses und der Stützen ergibt den Vorteil, daß das Gehäuse nicht dröhnt und nicht bricht und daß der Einbau des Motors erleichtert wird.The soft material of the housing and the supports has the advantage of that the housing does not boom or break and that the installation of the motor is made easier will.

Die Zeichnung zeigt das Gebläse nebst seinem Gehäuse und ein Beispiel der Aufhängung des Motors im Gehäuse. Der Motor ist nahe seinem einen Ende mittels zweier radialer Schrauben 7, die das Gehäuse 6 durchdringen und in Gewindewarzen 3 des Motorständers 2 eingeschraubt sind, zentriert und zugleich axial fixiert; und er ist nahe seinem anderen Ende durch zwei Stützen 5 aus weichem Kunststoff, die am Gehäuse mittels Schrauben befestigt sind, im Gehäuse zentriert. Das weichelastische Gehäuse ist durch die Schrauben und durch die Stützen aus seiner ursprünglichen runden Form in ovale Form verspannt; diese Spannung kann durch Drehung der Schrauben und durch Wahl der Stützenlänge so bemessen, also die Eigenfrequenz des Gehäuses kann so gewählt werden, daß sie von der Frequenz der vom Motor ausgehenden Erschütterungen genügend weit entfernt ist, Resonanz des Gehäuses zu vermeiden, soweit die Erschütterungen nicht schon durch weichen und daher stark dämpfenden Gehäusewerkstoff selbst verhindert werden. Die Weichheit des Werkstoffes des Gehäuses und der Stützen hat noch den fabrikatorischen Vorteil, daß die Löcher für die Schrauben mittels einer Ahle eingestochen und die Gewinde von den Schrauben selbst geschnitten werden können. Radiale Schrauben als Mittel, den Motor eines Gebläses im Gebläsegehäuse aufzuhängen, sind an sich bekannt. Und es ist auch bekannt, ein Gebläse, allerdings gehäuseloses Gebläse, mittels solcher radialen Schrauben in einem elastischen Metallring aufzuhängen.The drawing shows the fan together with its housing and an example the suspension of the motor in the housing. The engine is near its one end by means of two radial screws 7 which penetrate the housing 6 and are threaded into threads 3 of the motor stand 2 are screwed in, centered and at the same time axially fixed; and it is near its other end by two supports 5 made of soft plastic, which are fastened to the housing by means of screws, centered in the housing. The soft elastic The housing is out of its original state by the screws and the supports round shape braced into oval shape; this tension can be adjusted by turning the screws and dimensioned by choosing the length of the support, i.e. the natural frequency of the housing can be chosen so that it depends on the frequency of the vibrations emanating from the motor is sufficiently far away to avoid resonance of the housing as far as the shocks not already prevented by the soft and therefore strongly damping housing material itself will. The softness of the material of the housing and the supports still has the Manufacturing advantage that the holes for the screws are pierced with an awl and the threads can be cut from the screws themselves. Radial screws as a means of suspending the motor of a blower in the blower housing are in themselves known. And it is also known to have a blower, albeit a caseless blower, hang up by means of such radial screws in an elastic metal ring.
