Description
Elektrische Maschine, insbesondere Gleichstromerzeuger für Kraftfahrzeuge Die Erfindung bezieht sich auf eine elektrische Maschine, insbesondere Gleichstromerzeuger für Kraftfahrzeuge, mit einem vorzugsweise rohrförmigen Gehäuse, an dem mindestens an einer Stirnseite ein Lagerschild zentriert befestigt ist, der aus einer Blechkapsel besteht, die eine Nabe für die Lagerung der Läuferwelle aufweist.Electric machines, in particular direct current generators for motor vehicles The invention relates to an electrical machine, in particular a direct current generator for motor vehicles, with a preferably tubular housing on which at least a bearing plate is fastened in a centered manner on one end face and consists of a sheet metal capsule consists, which has a hub for the storage of the rotor shaft.
Bei einer bekannten Maschine dieser Art besteht die als Lagerschild dienende Blechkapsel aus zwei unabhängig voneinander hergestellten Teilen, nämlich aus einem im wesentlichen zylindrischen Kapselteil und einer daran Planschartig befestigten Blechplatte mit einer Nabe für die Lagerung der Läuferwelle. Diese aus zwei verschiedenen Ausgangsteilen hergestellte Ausführungsform ist jedoch insofern nachteilig, als ihre Herstellung aufwendig und umständlich ist.In a known machine of this type, there is a bearing plate serving sheet metal capsule made of two independently manufactured parts, namely from a substantially cylindrical capsule part and a puddle-like part thereon attached sheet metal plate with a hub for the storage of the rotor shaft. This out However, to this extent, embodiment produced two different starting parts disadvantageous as their production is expensive and cumbersome.
Der Erfindung liegt die Aufgabe zugrunde, eine als Lagerschild dienende Blechkapsel zu schaffen, deren Herstellung ein Minimum an Werkstoff, Arbeitszeit und Werkzeugen erforderlich macht.The object of the invention is to provide a bearing plate that serves as a bearing plate To create sheet metal capsules, the manufacture of which requires a minimum of material and labor and tools required.
Dies wird erfindungsgemäß dadurch erreicht, daß ein aus dem Boden der Blechkapsel ausgestanzter, länglicher, die Nabe für die Lagerung der Läuferwelle enthaltender Ausschnitt gegen die Längsachse des Stanzloches, vorzugsweise um etwa 90°. verdreht, an den an der Kapsel verbleibenden Boden-Reststreifen befestigt ist.This is achieved according to the invention that a from the ground of the sheet metal capsule punched out, elongated, the hub for the bearing of the rotor shaft containing cutout against the longitudinal axis of the punched hole, preferably by about 90 °. twisted, is attached to the remaining soil strips on the capsule.
In der Zeichnung ist als Ausführungsbeispiel des Gegenstandes der Erfindung ein Gleichstromerzeuger mit einer als Lagerschild dienenden Blechkapsel dargestellt. Es zeigt F i g. 1 den Gleichstromerzeuger in Richtung des Pfeiles I der F i g. 2 gesehen, F i g. 2 den Gleichstromerzeuger teilweise im Schnitt nach dem Linienzug II-II der F i g. 1, F i g. 3 einen Längsschnitt durch eine gezogene Blechkapsel ohne ausgestanzten Bodenausschnitt und F i g. 4 eine Ansicht der Blechkapsel mit ausgestanztem und verdreht befestigtem Bodenausschnitt. Der Gleichstromerzeuger hat ein rohrförmiges Gehäuse 10 und einen darin umlaufenden Läufer 11, der zusammen mit einem Stromwender 12 fest auf einer Welle 13 sitzt. Am Innenumfang des Gehäuses 10 sind zwei jeweils eine Erregerwicklung 14 tragende Polkerne 15 befestigt, von denen in F i g. 2 der eine teilweise sichtbar ist. Die Welle 13 ist an ihrem antriebsseitigen Ende in einem gegossenen Lagerschild 16 und an ihrem stromwenderseitigen anderen Ende in einer Blechkapsel 17 drehbar gelagert.In the drawing, as an embodiment of the subject matter Invention a direct current generator with a sheet metal capsule serving as a bearing shield shown. It shows F i g. 1 the direct current generator in the direction of arrow I. the F i g. 2 seen, F i g. 2 shows the direct current generator partly in section the line II-II of FIG. 1, Fig. 3 shows a longitudinal section through a drawn one Sheet metal capsule without a punched-out bottom cutout and FIG. 4 a view of the sheet metal capsule with punched out and twisted attached bottom cutout. The DC generator has a tubular housing 10 and a rotor 11 rotating therein, which together sits firmly on a shaft 13 with a commutator 12. On the inner circumference of the housing 10, two pole cores 15, each carrying an excitation winding 14, are fastened by those in Fig. 2 of which one is partially visible. The shaft 13 is on its drive side End in a cast bearing plate 16 and on its other on the commutator side End rotatably mounted in a sheet metal capsule 17.
Aus dem Boden der gezogenen Blechkapsel 17 ist ein länglicher, die Nabe 18 für die Lagerung des stromwenderseitigen Wellenendes enthaltender Ausschnitt 19 ausgestanzt, der um 90° gegen die Längsachse des Loches 20 im Kapselboden verdreht an den an der Kapsel verbleibenden Boden-Reststreifen 21 durch Schrauben 22 von außen her festgespannt ist. Die Blechkapsel 17 ist mit ihrem nach außen umgebogenen Öffnungsrand 23 zentriert an der Stirnseite des Gehäuses 10 befestigt. An dem ausgestanzten länglichen Bodenausschnitt 19 sind zwei nicht gezeichnete Halter für jeweils eine Schleifbürste 24 (s. F i g. 1) befestigt die bei zusammengebautem Gleichstromerzeuger durch zwei Schlitze 25 von außen her zugänglich sind.From the bottom of the drawn sheet metal capsule 17, an elongated cutout 19 containing the hub 18 for the storage of the commutator-side shaft end is punched out, which is rotated by 90 ° against the longitudinal axis of the hole 20 in the capsule bottom on the remaining bottom strips 21 on the capsule by screws 22 is clamped from the outside. The sheet metal capsule 17 is fastened with its outwardly bent opening edge 23 centered on the end face of the housing 10. Two holders (not shown) each for a grinding brush 24 (see FIG. 1) are attached to the punched-out elongated bottom cutout 19 and are accessible from the outside through two slots 25 when the DC generator is assembled.
