Die Erfindung "betrifft einen Generator, insbesondere Dr-»hstromgenerator für Fahrzeuge, mit hinein, wenigstens annähernd ringförmigen Ständerblechpaket, "bei. welchem an seinen Stirnseiten die Wickelkopfe der i ι den Ständer eingelegten Wicklung "vorstehen und in den Wi :kelköpfen Kühlrohre vorgesehen sind.The invention "relates to a generator, in particular a rotary current generator for vehicles, with in, at least approximately ring-shaped stator core, "with which on its end faces the winding heads of the winding inserted into the stator "protrude and provided cooling tubes in the angular heads are.
Maschinen dieser Art sind au.; dem I)E-GM 80 27 381.0 bekannt. Die dort empfohlene Verwendung von in die Wicklung eingelegten Kühlringen und Kiihlfahnen läßt es nicht zu, daß die Wicklungen maschine!1 hergestellt werden. Der Erfindung liegt die Aufgabe zugrunde, eine Kühlanordnui g zu schaffen, welche die maschinelle Herstellung der Wicklungen erlaubt. Hierzu wird erfindungsgemäß vorgeschlagen, daß die Wicklung in zwei Ein-zelsch ichtwicklunr.en unterteilt und daß zwischen je zwei zu einer der Einzelschichtwicklungen gehörenden Wickelköpfe mindestens '-in in rir gförmig in Umfangsrichtung des Ständers und gleichachsig zu dessen verlaufendes Kühlrohr eingesetzt is!·,.das an ein geschlossenes Kühlsystem - vorzugsweise mit Zwangsumlauf für ein flüssiges Kühlmittel - angeschlossen isi.Machines of this type are also available .; the I) E-GM 80 27 381.0 known. The recommended use of cooling rings and cooling vanes inserted in the winding does not allow that the windings machine! 1 are made. Of the The invention has for its object to provide a Kühlanordnui g to create which is the machining of the windings permitted. For this purpose, it is proposed according to the invention, that the winding is subdivided into two single-layer windings and that between each two to one of the single-layer windings belonging winding heads at least '-in in rir g-shaped in the circumferential direction of the stator and equiaxed to whose running cooling pipe is inserted! ·, .that an a closed cooling system - preferably with forced circulation for a liquid coolant - connected isi.

Zweckmäßige Ausgestaltungen ergeben sich aus den Unteransprüchen in Verbindung mit dem nachstehend beschriebenen Ausführungsbeispiel, das in der Zeichnung dargestellt ist.Appropriate refinements emerge from the subclaims in connection with what is described below Embodiment shown in the drawing.
Es zeigen Figur 1 einen axialen Längsschnitt durch den gewickelten Ständer eines Drehstromgenerators und Figur 2 den Ständer in der axialen Draufsicht, teilweise in unbewickeltem Zustand und teilweise im Schnitt durch die Wicklung und das Kühlrohr.

Der in der Zeichnung dargestellte Ständer 1 ist aus gestanzten Blechln.mellen geschichtet, und an seinem Außenumfang in bekannter Weise durch Schweißrippen oder·dergleichen zusammengehalten. An der Bohs'ungsseite 2 des Ständers 1 sind über den Umfang verteil'- drei im einzelnen nicht näher dargestellte Drehstromwicklungen vorgesehen: Diese · Wicklungen sind jeweils in zwei Einzelschichtwicklungen unterteilt, nämlich eine am Irund der Nuten- 3 liegende erste Einzelsehi entwicklung ι- und eine in den Wüten über dieser liegende 'zweite EinzeLschichtwicklung 5. Die Wickelköpfe dies.-r Einzelsehichtwieklungen . sind -in Figur 1 und 2 mit 7 un>t 8 bezeichnet.The stand 1 shown in the drawing is layered from stamped sheet metal cells, and on its outer circumference in a known manner by welding ribs or the like held together. On the Bohs'ungsseite 2 of the stand 1 are not distributed over the circumference three in detail three-phase windings shown in more detail are provided: These Windings are each in two single-layer windings divided, namely one lying on the Irund the groove 3 first individual development and one in the rage about this lying second single-layer winding 5. The winding heads dies.-r individual visual effects. are -in Figure 1 and 2 denoted by 7 and> t 8.
Gemäß der linken Hälfte der '"igur 1 ist zwischen die beide Wickelkopf'· 7 und 8 ein ursprünglich im Querschnitt kreisz/lindrisc lies Kühlrohr 9 eingelegt, das zu einem entlang dem U.afang des Ständers 1 verlaufenden Ring gebogen ist und die ΰ ■-änderachV.e 10 konzentrisch umgibt. Das Rohr 9 ist durch r idialen Preßdruck im Querschnitt oval bis elliptisch verfirmt, wob.-i die Längsachse des in Figur 1 dargestellten Q ier schnit I.3 parallel zur Drehachse . 1 0 verläuft. "Das RohrAccording to the left half of the figure 1 is between the two Winding head '7 and 8 originally had a circular / lindrisc cross-section read cooling tube 9 inserted, which leads to a along the U.afang of the stand 1 extending ring is bent and the ΰ ■ -änderachV.e 10 surrounds concentrically. The pipe 9 is through r idial pressure in cross-section oval to elliptical confirmed, wob.-i is the longitudinal axis of the one shown in FIG Q ier cuts I.3 parallel to the axis of rotation. 1 0 runs.

9 ist an ein Zwangsumlauf sys tem, beispielsweise an den Ölkreislauf einer den Drehstromgenerator antreibenden Brennkraftmaschine angeschlossen. Das im Rohr 9 fließende Öl nimmt einen beträchtlichem Anteil der in d<-n Wicklungen erzeugten Stromwärme auf, was -,ur Folge hut, daß der Generator mit wesentlich höherer Leistung bezogen auf das spezifische Eisen- und Kupf e rvolum^.n betrieben werden kann. 9 is connected to a forced circulation system, for example to the oil circuit of an internal combustion engine driving the alternator. The oil flowing in the pipe 9 absorbs a considerable proportion of the current heat generated in the windings, which has the consequence that the generator can be operated with a significantly higher output based on the specific iron and copper volume can.

Dort ;iind zwischen die ebenfalls mit T und 8 bezeichneten Wickelköpf'- der beiden Einzelschichtwicklungen h und 5 vier Windungen 11 bis 1k eines durchgehend gleichen Querschnitt aufweisenden Kupferrohres 15 eingelegt, das mit dem Schmierölkre.i slauf einer Brennkraftmaschine oder einem sonstigen l'^ang: umlauf system "verbunden werden kann. Die dargestellten Windungen 11 bis 1U haben ,jeweils gleichen W'indungsdurchm<is ser und können in weiterer Abwandlung aus Einzelnindungen bestehen, die jeweils an ihren Enden untereinander verbunden und an ein Zwangsumlauf system für ein Kühlmittel angeschlossen sein können.In the right half of Fi 1 -; ur 1, a modified embodiment is shown. There; iind between the winding heads, also designated T and 8, of the two single- layer windings h and 5, four turns 11 to 1 k of a copper pipe 15 with the same cross-section throughout, which is connected to the lubricating oil circuit of an internal combustion engine or another l '^ ang: circulation system "can be connected. The turns 11 to 1U shown each have the same winding diameter and, in a further modification, can consist of individual windings, each of which is connected to one another at its ends and connected to a forced circulation system for a coolant could be.
