Description

Zur Einsparung von Kupfer bzw. zur Erhöhung der Sicherheit ist es bereits bekannt, den mechanisch beanspruchten Teil des Kollektorsegmentes aus Stahl oder einem anderen geeigneten Baustoff herzustellen. Der obere Teil des Kollektorsegmentes besteht hierbei vollständig aus Kupfer. Es ist auch schon vorgeschlagen worden, nur für denjenigen Teil des Kollektorsegmentes, auf dem die Bürsten schleifen, Kupfer zu verwenden. Hierbei wurden der Stahl- und der Kupferteil im Gießverfahren miteinander verbunden.To save copper or to increase security it is already known, the mechanically stressed part of the collector segment made of steel or another suitable building material. The upper part of the collector segment consists entirely of copper. It has also been suggested only for that part of the collector segment on which the brushes grind, copper to use. Here, the steel and copper parts were cast together tied together.

Die Erfindung verbessert derartige Kollektoren und vereinfacht ihre Herstellung dadurch, daß der Kupferteil des Kollektorsegmentes in dem aus Stahl oder einem anderen Metall bestehenden Teil des Kollektors eingeschrumpft ist.The invention improves and simplifies such collectors Manufactured in that the copper part of the collector segment is made of steel or another metal part of the collector is shrunk.

Die Erfindung ist in den Fig. i und 2 der Zeichnung beispielsweise veranschaulicht.The invention is illustrated in Figures i and 2 of the drawings, for example illustrated.

Mit i ist der aus Stahl oder einem anderen geeigneten Werkstoff bestehende Teil des Kollektorsegmentes bezeichnet. Die Anschlußfahne 2 für das Einlöten der Ankerstäbe der elektrischen Maschine kann zweckmäßigerweise mit dem Teil i aus einem Stück bestehen. Wie aus Fig. i ersichtlich ist, besteht nur derjenige Teil 3, der von den Bürsten bestrichen wird, aus Kupfer. Gemäß der Erfindung ist der Kupferteil 3 in dem Metallteil i durch Schrumpfung des Metallteiles i befestigt. Gegebenenfalls kann, sofern erforderlich, darüber hinaus noch eine zusätzliche Befestigung des Kupferteiles 3 in dem Stahlteil i durch andere Befestigungsmittel, z. B. durch Löten, Schweißung, Verstiften, erfolgen.Where i is made of steel or another suitable material Part of the collector segment referred to. The terminal lug 2 for soldering the Armature rods of the electrical machine can expediently with the part i from one Piece. As can be seen from Fig. I, there is only that part 3, the is painted by the brushes, made of copper. According to the invention, the copper part is 3 fixed in the metal part i by shrinking the metal part i. Possibly If necessary, an additional attachment of the Copper part 3 in the steel part i by other fastening means, e.g. B. by soldering, Welding, pinning, take place.

Die Schrumpfspannung und damit also die zum Einschrumpfen des Kupferteiles 3 in den Metallteil i erforderliche Erwärmung des Metallteiles i ist zweckmäßigerweise je nach der zu erwartenden Betriebstemperatur festzulegen. Die Schrumpfspannung wird derart gewählt, daß auch bei der Betriebstemperatur noch ein fester Sitz des Kupferschleifstückes 3 gewährleistet ist.The shrinkage stress and thus the one for shrinking the copper part 3 in the metal part i required heating of the metal part i is expedient to be determined depending on the expected operating temperature. The shrinkage stress is chosen so that even at the operating temperature there is still a tight fit of the Copper slider 3 is guaranteed.

Die Erfindung ist nicht auf das in der Fig. i dargestellte Ausführungsbeispiel beschränkt. Es kann der Kupferteil 3 auch aus mehreren Teilen bestehen, beispielsweise, wie in der Fig. 2 dargestellt, aus zwei Teilen 3. Ferner kann zur Verbesserung des Stromüberganges zwischen dem Kupferteil 3 und dem Metallteil i der Metallteil i an der Stromübergangsstelle 4 versilbert oder mit einer Silberplattierung oder Silberauflage versehen werden. Es kann aber auch der Kupfereinsatz 3 an den Übergangsflächen galvanisch durch Spritzen od. dgl, eine Silberauflage erhalten.The invention is not limited to the embodiment shown in FIG limited. The copper part 3 can also consist of several parts, for example as shown in FIG. 2, of two parts 3. Furthermore, to improve the Current transition between the copper part 3 and the metal part i of the metal part i Silver-plated at the current transition point 4 or with a silver plating or silver plating be provided. However, the copper insert 3 can also be galvanized at the transition surfaces by spraying od. The like, a silver plating obtained.
