Description
Elektromotor zum Antrieb von Nähmaschinen Bei den Elektromotoren zum Antrieb von Nähmaschinen spielt die Bauart eine erhebliche Rolle. Diese Motoren, die an dem Oberteil der Nähmaschinen angebracht werden, sollen mit dem Oberteil versenkt oder verdeckt werden können. Da bezüglich dieser Bedingungen gegebene Verhältnisse vorhanden sind, so muß die Bauart diesen angepaßt werden'.Electric motor for driving sewing machines With the electric motors for The type of drive used in sewing machines plays a significant role. These engines, which are attached to the upper part of the sewing machine, should with the upper part can be sunk or covered. As given conditions with regard to these conditions are available, the design must be adapted to these '.
Man hat nun schon versucht, zur Aufnahme der Polschuhe, Bürsten, Lager usw., :einen aus Dynamoblechen festgefügten, parallel zur Motorachse angeordneten Rahmen anzuwenden. Diese Rahmen sind aber nicht in sich vollständig geschlossen; infolgedessen ist die Einrichtung nicht vollkommen; denn die Lagerstellen müssen auf jeden Fall unveränderlich sein, was bei .einem nicht geschlossenen Rahmen in Frage gestellt ist.Attempts have already been made to accommodate the pole pieces, brushes, bearings etc.,: one made of dynamo sheets, arranged parallel to the motor axis Apply frame. However, these frames are not completely self-contained; consequently the establishment is not perfect; because the camps must in any case be unchangeable, which is the case with a non-closed frame in Question is asked.
Dieser Mangel wird erfindungsgemäß, dadurch vermieden, daß ein aus Dynamoblechen hergestellter, in sich vollständig geschlossener Rahmen benutzt wird. Ein solcher gewährleistet bei einer gleichmäßigen, flachen Form die Unveränderlichkeit der Stellung der Lagerschalen zueinander und verhindert somit jede Lockerung des Motors.According to the invention, this deficiency is avoided in that a Dynamo sheet produced, completely closed frame is used. This guarantees immutability in the case of a uniform, flat shape the position of the bearing shells to each other and thus prevents any loosening of the Engine.
In der Zeichnung ist der Motor beispielsweise dargestellt, und zwar zeigt Abb. i den Motor, angebaut an dem Oberteil der Nähmaschine.In the drawing, the engine is shown as an example, namely Fig. i shows the motor, attached to the upper part of the sewing machine.
Abb. 2, 3 und ¢ zeigt den Motor in Längs-und Querschnitt sowie in Ansicht.Fig. 2, 3 and ¢ shows the engine in longitudinal and cross-section as well as in Opinion.
Abb.5 und 6 zeigt das Gehäuse von der Seite und von oben gesehen.Figures 5 and 6 show the case from the side and from above.
In einem aus Dynamoblechen durch Nieten festgefügten rechtwinkligen Rahmen i sind Buchsen 3 angeordnet, zwischen denen der Anker 2 gelagert ist. Durch diese Buchsen geht die Achse 9 hindurch. Zwischen diesen Buchsen befindet sich auf der Achse 9 ein Metallrohr B. Der Ankerträger 2 und der Kollektor 7 sind auf dieses Metallrohr gepreßt. Die Befestigung des Ventilators i i erfolgt durch die Schraube io, durch die auch zu gleicher Zeit das Metallrohr 8 und die Achse 9 verbunden werden.In a right-angled one made of dynamo sheets with rivets Frame i are sockets 3, between which the armature 2 is mounted. By these sockets go through the axis 9. Between these sockets is on the axis 9 a metal tube B. The armature support 2 and the collector 7 are on this Pressed metal pipe. The fan i i is fastened by means of the screw io, through which the metal tube 8 and the axle 9 are connected at the same time.
In den langen Schenkeln des Rahmens i sind die Bürstengarnituren q. untergebracht, -,nährend :an dessen Innenseiten die Polschuhe 5 mittels der Schrauben 6 befestigt sind.The brush sets q are in the long legs of the frame i. housed, -, nourishing: on the insides of the pole shoes 5 by means of the screws 6 are attached.
Das Ganze ist durch die Verschlußdeckel 12 und 13 abgeschlossen, die durch die Schrauben i4., die quer durch den Rahmen hindurchführen, finit diesem verbunden sind. Die Verschlußdeckel 12, 13 können mit Lüftungsausschnitten versehen sein. An dem Längsrand eines Verschlußdeckels 12 snidzwei Augen 15 angeordnet, die zur Aufhängung des Motors an dem Halter 16 dienen. Eine Feder 17 bewirkt durch Abdrücken des Motors die Spannung des Riemens oder, bei Reibungsantrieb umgekehrt wirkend, die Anpressung der Reibrolle an das Schwungrad der Nähmaschine.The whole thing is completed by the closure covers 12 and 13 , which are finitely connected to the frame by the screws i4. The closure cover 12, 13 can be provided with ventilation cutouts. Arranged on the longitudinal edge of a closure cover 12 are two eyes 15 which serve to suspend the motor on the holder 16. By pressing the motor, a spring 17 causes the belt to be tensioned or, in the case of a friction drive acting in reverse, the friction roller is pressed against the flywheel of the sewing machine.
