Description

Bürstenhalter für Kleinmotoren, insbesondere für Nähmaschinen motoren, mit gabelförmiger, den Bürstenhalter auf seinen Sitz drückender Halterstütze Es sind Bürstenhalter bekannt, die die Isolierhülsen der Bürsten von Kleinmotoren gabelförunig umfassen, wobei die Hülsen von außen gegen die Motorwand gepreßt werden.Brush holder for small motors, especially for sewing machine motors, with fork-shaped holder support Es that presses the brush holder onto its seat Brush holders are known that fork-shaped the insulating sleeves of the brushes of small motors include, wherein the sleeves are pressed from the outside against the engine wall.

Gemäß der Erfindung werden die von gabetförmigen Haltern umfaßten Isolierhülsen der Bürsten. innerhalb des Motorgehäuses angeordnet, wobei: die Anpreisung der Bürsten gegen den Lagerschild durch eine ann Magnetgestell angebrachte Anpreßvorrichtung erfolgt. Die Aaspressung der Hülsen kann entweder durch die federnd ausgebildeten Halter selbst erfolgen, die fest mit dem Magnetgestell verbunden sind, oder durch Federn o. dgl., die das verschiebbar angeordnete Magnetgestell mit den Haltern gegen die am Lagerschild angebrachten Widerlager für die Hülsen. pressen.According to the invention, those are comprised of gabion-shaped holders Brush insulation sleeves. arranged within the motor housing, wherein: the promotion the brushes against the end shield by a pressure device attached to the magnet frame he follows. The sleeves can either be pressed out by the resilient ones Holders take place, which are firmly connected to the magnetic frame, or by Springs or the like that counteract the displaceably arranged magnetic frame with the holders the abutments for the sleeves attached to the end shield. press.

Die Vorteile dieser Bauweise sind die, daß der Motor durch die innerhalb des Gehäuses angebrachten Bürsten weniger sperrig ist, sich also besser als andere Motoren für den Einbau in Nähmaschinen eignet. Ferner ist für die Bürsten ein unbedingt sicherer Halt gewährleistet, und die Bürsten lassen sich ohne weiteres leicht nachstellen. Beides. trifft bei. den bekannten Ausführungen mit Gabelhaltern nicht zu.The advantages of this design are that the engine is through the inside The brush attached to the housing is less bulky and therefore better than others Motors suitable for installation in sewing machines. Furthermore, one is essential for the brushes A secure hold is guaranteed and the brushes can be easily adjusted without further ado. Both. applies to. the known designs with fork holders not to.

In der Zeichnung ist eine Vorrichtung gemäß der Erfindung dargestellt, und zwar zeigt Abb. i eine Stirnansicht und Abb. a eine Seitenansicht der Burstenhalter; Abb. 3 zeigt eine Aufsicht auf eine Halterstütze, während Abb. 4. ein Schema des ganzen Motors veranschaulicht.In the drawing, a device according to the invention is shown, namely Fig. i shows a front view and Fig. a shows a side view of the brush holders; Fig. 3 shows a top view of a holder support, while Fig. 4 shows a diagram of the whole engine illustrated.

Die Bürsten sind in Isolierhülsen i befestigt, die mit seitlichen Aussparungen z versehen sind. Mit diesen werden die IsoMerhülsen über gabelförmige Halter 3 geschoben, die am Magnetgestell q befestigt sind. Die gab.elförxnigen Halter können auch, wie bei 3a gezeigt, federnd ausgeführt sein. Wenn die Halter 3 nicht federnd ausgebildet sind, so wird .das Magnetgestell q. innerhalb des Gehäuses 5 verschiebbar angeordnet und durch Federn 6 oder eine Schraubvorrichtung nach rechts gegen die Isolierhülsen i und diese gegen den Lagerschild 7 gedrückt, das entsprechende Widerlager 8 aufweist. An den Haltern, z. B. an abwärts gebogenen Schenkeln 9 des Bürstenhalters, können weitere-Maschinenteil:e, z. B. eine Schaltbrücke aus Isolierstoff, angebracht werden.The brushes are fastened in insulating sleeves i, with the lateral ones Recesses z are provided. With these the IsoMerhülsen are fork-shaped Holder 3, which are attached to the magnet frame q. The gave.elförxnigen holder can also, as shown at 3a, be resilient. If the holder 3 does not are resilient, so .das magnet frame q. inside the housing 5 Slidably arranged and by springs 6 or a screw device to the right pressed against the insulating sleeves i and these against the bearing plate 7, the corresponding Has abutment 8. On the holders, e.g. B. on downwardly curved legs 9 of the Brush holder, can further-machine part: e, z. B. a switching bridge made of insulating material, be attached.
