Description
Die Erfindung betrifft einen Nutenverschluß für elektrische Maschinen, insbesondere mit hoher Wärmebeständigkeit. Um die Einbringung in die Nut und die Herstellung des Verschlusses zu erleichtern, ist es bekannt, unter anderem auch Bänder oder Schnüre aus anorganischem Material wie Asbest, Glas, Quarzwolle zu verwenden, mit denen nach dem Einträufeln der Wicklung die Nut ausgefüllt wird. Um einen festen Sitz der Wicklung zu erhalten, wird diese Füllung mit Isoliermasse, Lack, härtbarern Kunstharz od. dgl. getränkt. Es ist ferner bekannt, beim Wickeln zusätzliche elastische Füllstücke aus Gummi in die Nut einzulegen und, die Nut nach dem Einlegen der Wicklung zu verkeilen.The invention relates to a slot lock for electrical machines, especially with high heat resistance. To the introduction into the groove and the To facilitate manufacture of the fastener, it is known, among other things, too To use tapes or cords made of inorganic material such as asbestos, glass, quartz wool, with which the groove is filled after the winding has been instilled. To a firm To get the winding fit, this filling is made with insulating compound, varnish, hardenable Synthetic resin or the like soaked. It is also known to use additional elastic when winding Insert rubber fillers into the groove and, after inserting the winding, the groove to wedge.
Die Erfindung hat die Aufgabe, das Verschließen der Nuten. einfacher als bisher zu gestalten und einen Nutenverschluß zu schaffen, der hitzebeständig und mechanisch hochwertig ist. -Erfindungsgemäß besteht derVerschluß aus einer Schnur oder einem Schlauch aus beim Einlegen in die Nut nicht völlig aasvulkanisiertem und erst unter der Wirkung der Trockentemperatur des Wicklungtränklackes bzw. der höheren Betriebstemperatur aasvulkanisierten und hart gewordenem Si.likonkautschuk. Die Vulkanisation von Silikonkautschuk verläuft ohne Schwefelzusatz. Mit der Vulkanisation von Kautschuk hat sie nur das eine gemein sam, daß es sich auch hier um eine Vernetzung handelt. Die erforderliche Vernetzung, die durch organische Peroxyde erfolgen kann, kann stufenweise durch Temperatursteuerung erreicht werden. Das Verfahren zum Verschließen der Nut wird so durchgeführt, daß eine runde Schnur oder ein Schlauch auf den Nutenschlitz gelegt wird und dann durch diese in die Nut eingedrückt oder mittels eines geeigneten spachtelförm.igen Werkzeuges hindurchgeschlagen wird.The invention has the task of closing the grooves. easier to design than before and to create a groove lock that is heat-resistant and is of high mechanical quality. According to the invention, the closure consists of a cord or a hose made of material that is not completely vulcanized when it is inserted into the groove and only under the effect of the drying temperature of the winding impregnating varnish or the Higher operating temperature vulcanized and hardened silicon rubber. The vulcanization of silicone rubber takes place without the addition of sulfur. With vulcanization all it has in common with rubber is that it is also a network acts. The necessary crosslinking, which can be done by organic peroxides, can be achieved in stages through temperature control. The procedure for sealing the groove is carried out so that a round cord or hose is placed on the groove slot is placed and then pressed through this into the groove or by means of a suitable spatula-shaped tool is knocked through.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt. In die halbgeschlossene Nut i ist die Wicklung 2 eingeträufelt. Oberhalb der Wicklung ist ein Nutenv erschluß 3 aus Silikonkaut§chuk angeordnet, der den Nutenschlitz 4 verschließt. Da der Schlauch aus elastischem Material besteht, läßt er sich unter Deformation. durch den engen Nutenschlitz zwängen und breitet sich dann in den wicklungsfreien Nutenraum so aus, daß er diesen vollständig ausfüllt. Man kann dabei den Schlauch oder die Schnur auf den Nutemschlitz legen und mittels eines spachtelförmigen Werkzeugen von einem Ende der Nut beginnend durch den Schlitz hindurchschlagen. Für den Schlauch oder die Schnur wird ein nicht ganz ausvulkan;isiertes Material verwendet, das erst bei höheren Betriebstemperaturen der Maschine völlig aasvulkanisiert und hart wird.An embodiment of the invention is shown in the drawing. The winding 2 has trickled into the semi-closed slot i. Above the winding a Nutenv closure 3 made of silicone rubber is arranged, which the groove slot 4 locks. Since the hose is made of elastic material, it can be underneath Deformation. Force through the narrow groove slot and then spreads into the winding-free Groove space so that it completely fills it. You can use the hose or lay the cord on the slot and use a spatula-shaped tool Starting at one end of the groove, knock it through the slot. For the hose or the cord is made of a material that is not completely vulcanized; at higher machine operating temperatures it becomes completely vulcanized and hard.
Die Erfindung bietet folgende Vorteile: Ein nachheriges Behandeln .des Nuten.verschlusses durch Tränken mit härtbarem Kunstharz od. dgl. ist nicht erforderlich. Der Nutenverschluß ist hitzebeständig und mechanisch hochwertig. Gegenüber Nutenverschlußkeilen aus Schichtstoffen, beispielsweise aus Silikon und Glasgewebe besitzt der Nutenverschluß gemäß der Erfindung bei gleichem Füllfaktor eine größere Festigkeit, da die festen Keile nur aus dünnen Streifen bestehen können, die den Schlagbeanspruchungen beim Einsetzen in die Nut unter Umständen nicht standhalten und abbrechen.The invention offers the following advantages: Subsequent treatment .of the slot closure by impregnation with hardenable synthetic resin or the like is not necessary. The groove lock is heat-resistant and mechanically of high quality. Opposite to Groove wedges made of laminates, for example made of silicone and glass fabric the groove lock according to the invention has a larger one with the same fill factor Strength, as the solid wedges can only consist of thin strips that form the Under certain circumstances, it may not be able to withstand impact loads when inserting into the groove and cancel.
