Description

Die Erfindung betrifft eine Luftfördervorrichtung in einer Textilmaschine.The The invention relates to an air conveying device in one Textile machine.

Viele Textilmaschinen enthalten An/Absaugvorrichtungen, mittels denen Flug, gebrochene Lunten oder Fäden, Fasern und der gleichen ab- oder angesaugt werden. An Vorspinn- und Spinnmaschinen sind dies vor allem Fadenabsaugvorrichtungen. Derartige Luftfördervorrichtungen bestehen in aller Regel aus einem in einem Gehäuse angeordneten Lüfterrad mit Luftschaufeln, das durch einen Elektromotor angetrieben wird.Lots Textile machines contain suction / suction devices by means of which Flight, broken tunics or threads, fibers and the same be sucked off or sucked. On roving and spinning machines are this especially Fadenabsaugvorrichtungen. Such air conveying devices usually consist of a arranged in a housing Fan with air blades, by an electric motor is driven.

Häufig ist dabei zwischen Elektromotor und Lüfterrad ein Vorgelege eingeschaltet ( US 2,946,174 ), das den Vorteil bietet, die Drehzahl und damit das geförderte Luftvolumen durch Wechseln der Riemenscheiben an unterschiedliche Anforderungen anpassen zu können.Often, a countershaft is switched on between the electric motor and the fan wheel ( US 2,946,174 ), which offers the advantage of being able to adapt the speed and thus the volume of air delivered by changing the pulleys to different requirements.

Es sind aber auch Absaugvorrichtungen bekannt ( DE 1 877 417 U1 ), bei denen das Lüfterrad direkt auf der Welle des Läufers des Elektromotors angeordnet ist. Bei frequenzgesteuerten Elektromotoren kann hierbei die Drehzahl des Lüfterrades durch die Speisefrequenz des Elektromotors bestimmt werden.But there are also known suction devices ( DE 1 877 417 U1 ), in which the fan is arranged directly on the shaft of the rotor of the electric motor. In the case of frequency-controlled electric motors, the speed of the fan wheel can be determined by the feed frequency of the electric motor.

Der Erfindung war daher die Aufgabe gestellt, für eine Luftfördervorrichtung in einer Textilmaschine, die ein Lüfterrad und einen dieses Lüfterrad antreibenden Elektromotor umfasst, einen einfacheren, in der Fertigung kostengünstigeren und geringere Bautiefe aufweisenden Aufbau vorzuschlagen. Sie löst diese Aufgabe mit den im Hauptanspruch aufgeführten Merkmalen.Of the Invention was therefore the object of an air conveyor in a textile machine that has a fan and this one Impeller-driving electric motor includes, a simpler, less expensive and smaller depth in production suggesting construction. She solves this task with the features listed in the main claim.

Dadurch, dass der Elektromotor als Axialfeldmotor ausgeführt ist, kann die Baulänge der Luftfördervorrichtung wesentlich vermindert werden, weil Axialfeldmotoren konstruktionsbedingt eine geringe Baulänge aufweisen.Thereby, that the electric motor is designed as axial field motor, The length of the air conveyor can significantly be reduced because axial field motors by design a have a small length.

Die Bautiefe kann vermindert werden, wenn das Lüfterrad auf einem Achsstummel des Ständers des Motors drehbar gelagert ist.The Depth can be reduced when the fan on a stub axle of the stator of the engine rotatably mounted is.

Wenn die Permanentmagnete des Läufers auf der dem Ständer zugewandten Fläche des Lüfterrad angebracht sind, kann der scheibenförmige Läufer in das Lüfterrad integriert werden. Insofern weist die Luftfördervorrichtung keinen gesonderten Läufer mehr auf. Dieser Aufbau verbilligt daher auch den Motor.If the permanent magnets of the rotor on the stand facing surface of the fan wheel are mounted, can the disc-shaped runner in the fan to get integrated. In this respect, the air conveyor device no separate runner more. This structure is cheaper hence the engine.

Das dichte Heranrücken des Lüfterrades an den Ständer des Elektromotors bietet die vorteilhafte Möglichkeit, das Lüfterrad zur Kühlung des Elektromotors heranzuziehen. Hierzu kann das Lüfterrad auf seiner dem Ständer zugewandten Fläche mit Luftschaufeln versehen werden, die Kühlluft zu Kühlrippen am Ständer fördern.The tight approach of the fan wheel to the stand of the electric motor offers the advantageous possibility to use the fan to cool the electric motor. For this purpose, the fan wheel on its the stand facing surface are provided with air blades, the Feed cooling air to cooling fins on the stand.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung schematisch dargestellt. Sie zeigt den Schnitt durch die Luftfördervorrichtung in Ebene durch dessen Längsachse.In The drawing is an embodiment of the invention shown schematically. It shows the section through the air conveyor in plane through its longitudinal axis.

Die Luftfördervorrichtung 1 wird durch einen Elektromotor 2 angetrieben, der als Axialfeldmotor ausgebildet ist. Der Ständer 3 des Elektromotors weist mehrere, im Kreis angeordnete Erregerwicklungen 5 mit Magnetpolen 4 auf, denen in axialer Richtung an einem Lüfterrad 6 angeordnete Permanentmagnete 7 gegenüber stehen. Das Magnetfeld des Motors verläuft also axial. Bei 8 ist die Zuleitung zum Elektromotor dargestellt.The air conveyor 1 is by an electric motor 2 driven, which is designed as Axialfeldmotor. The stand 3 the electric motor has a plurality of exciter windings arranged in a circle 5 with magnetic poles 4 on, those in the axial direction on a fan 6 arranged permanent magnets 7 stand opposite. The magnetic field of the motor thus runs axially. at 8th the supply line to the electric motor is shown.

Das Lüfterrad 6 geläufiger Bauart weist eine Ansaugöffnung 9 und Leitschaufeln 10 auf, durch die die angesaugte Luft radial abgefördert wird. Es versteht sich, dass das Lüfterrad in einem hier nicht wiedergegebenem Gehäuse angeordnet ist.The fan wheel 6 Common design has a suction port 9 and vanes 10 on, through which the sucked air is discharged radially. It is understood that the fan is disposed in a housing not reproduced here.

Die Permanentmagnete 7 des Elektromotors 2 sind in einem Ringraum 11 auf der der Ansaugöffnung 9 abgewandten Seite des Lüfterrades 6 befestigt. Insofern kann gesagt werden, dass der Elektromotor keinen eigentlichen Läufer aufweist, vielmehr kann dieser als Bestandteil des Lüfterrades gelten.The permanent magnets 7 of the electric motor 2 are in an annulus 11 on the intake 9 opposite side of the fan 6 attached. In this respect, it can be said that the electric motor has no actual runner, but this can be considered part of the fan.

Der Ständer 3 des Elektromotors 2 hat einen Achsstummel 12, auf dem die Einheit Lüfterrad 6 und der Scheibe mit den Permanentmagneten 7 gelagert ist. Die Lagerung dieser Einheit besteht vorteilhaft aus zwei Wälzlagern 13.The stand 3 of the electric motor 2 has a stub axle 12 on which the unit fan wheel 6 and the disc with the permanent magnets 7 is stored. The storage of this unit is advantageously made of two bearings 13 ,

Das Gehäuse des Ständers 3 ist auf seiner dem Lüfterrad 6 zugewandten Fläche mit radialen Kühlrippen 14 versehen. Die dieser Fläche gegenüberstehende Fläche des Lüfterrades ist mit kleinen Luftschaufeln 15 versehen, die bei Rotation Umgebungsluft an den Kühlrippen 14 vorbeistreifen lassen. Diese Umgebungsluft wird jedoch im Wesentlichen nur im Raum zwischen Ständer und Lüfterrad umgewälzt und erwärmt sich im Betrieb des Ansauglüfters.The housing of the stand 3 is on his the fan 6 facing surface with radial cooling ribs 14 Mistake. The area of the impeller facing this surface is with small air blades 15 provided that when rotating ambient air at the cooling fins 14 let fly by. However, this ambient air is essentially circulated only in the space between the stator and the fan and heats up during operation of the intake fan.

Alternativ kann daher – wie nicht näher dargestellt – vorgesehen sein, in der dem Ständer 3 zugewandten Fläche des Lüfterrades 6 dicht neben dem die Permanentmagnete 7 enthaltenden Ringraum 11 Öffnungen vorzusehen, durch die Luft angesaugt und durch die Leitschaufeln des Lüfterrades abgeführt werden kann. Diese Luft kann ständig aus der Umgebung angesaugt werden und ist daher kühler als die nur umgewälzte Luft. Diese Kühlluft vermindert zwar die Förderleistung des Lüfterrades geringfügig. Dies kann jedoch durch entsprechende Dimensionierung des Lüfterrades ohne weiteres kompensiert werden.Alternatively, it can therefore - as not shown in detail - be provided in the stand 3 facing surface of the fan wheel 6 close to the permanent magnets 7 containing annulus 11 Provide openings through which air can be sucked and discharged through the guide vanes of the fan wheel. This air can be constantly sucked from the environment and is therefore cooler than the only recirculated air. Although this cooling air reduces the flow rate of the fan slightly. However, this can be done by appropriate Di dimensioning of the fan wheel can be easily compensated.
