Description

Die Erfindung betrifft Schaltwelle zur Betätigung von Schaltkontakten eines mehrpoligen elektrischen Leistungsschalters mit von einem zentralen, für eine drehbare Lagerung bestimmten Wellenschaft abragenden Hebeln aus Druckguß zur Verbindung der Schaltwelle mit den Schaltkontakten und mit einem die Schaltkontakte betätigenden Energiespeicher. Ferner betrifft die Erfindung ein Verfahren zur Herstellung einer solchen Schallwelle.The invention relates to control shaft for actuating switch contacts a multi-pole electrical circuit breaker with a central one intended for a rotatable bearing Die-cast levers protruding from the shaft for connection the selector shaft with the switch contacts and with a the switch contacts actuating energy storage. Furthermore concerns the invention a method for producing such Sound wave.

Eine Schaltwelle der genannten Art ist durch die
DE 197 27 853 C1 bekanntgeworden. Um die Herstellung relativ langer Schaltwellen zu erleichtern, wie sie beispielsweise für vierpolige Leistungsschalter und solche mit hohem Bemessungsstrom benötigt werden, ist nach dem genannten Dokument vorgesehen, kürzere Schaltwelleneinheiten miteinander zu kuppeln. Demgegenüber würde es vorteilhaft erscheinen, wenn für alle Baugrößen einer Baureihe von Leistungsschaltern einstükkige Schaltwellen gleichartiger Beschaffenheit bereitgestellt werden können, für deren Herstellung das gleiche Verfahren zum Einsatz kommt. Der Erfindung liegt die Aufgabe zugrunde, eine Schaltwelle mit diesen Eigenschaften zu schaffen.A switching shaft of the type mentioned is by
DE 197 27 853 C1 became known. In order to facilitate the production of relatively long switching shafts, as are required, for example, for four-pole circuit breakers and those with a high rated current, the document mentioned provides for coupling shorter switching shaft units to one another. In contrast, it would appear to be advantageous if one-piece switching shafts of a similar nature can be provided for all sizes of a series of circuit breakers, the same method being used for their production. The invention has for its object to provide a control shaft with these properties.

Gemäß der Erfindung wird die vorstehende Aufgabe dadurch gelöst, daß der Wellenschaft durch einen Abschnitt eines rohrförmigen Halbzeuges aus einem Metall gebildet ist, das einen höheren Schmelzpunkt als die von dem Wellenschaft abragenden Hebel aufweist, und daß die Hebel auf dem Wellenschaft befestigt sind. According to the invention, the above object is achieved in that that the shaft shaft through a section of a tubular Semi-finished product is formed from a metal, the one higher melting point than that protruding from the shaft Has lever, and that the lever is attached to the shaft are.

Durch die Erfindung werden die Vorteile von Schaltwellen, die aus vorgefertigten Einzelteilen durch Löten oder Schweißen hergestellt werden und solchen, die nach der erwähnten DE 197 27 853 Cl als Druckgußteile hergestellt sind, miteinander kombiniert. Durch die Aufbringung der Hebel auf einen Wellenschaft aus rohrförmigem Halbzeug können Schaltwellen mit jeder benötigten Länge und mit jeder benötigten Anzahl von Hebeln preiswert hergestellt werden. Die vorteilhaften Eigenschaften der neuen Schaltwelle stehen damit im Zusammenhang, daß Druckgußteile geringerer Größe herzustellen sind als es nach der erwähnten DE 197 27 853 Cl der Fall ist. Unter anderem wird hierdurch der Aufwand für die Qualitätssicherung wesentlich verringert.By the invention, the advantages of switching shafts, the from prefabricated individual parts by soldering or welding are produced and those which are in accordance with the aforementioned DE 197 27 853 Cl are manufactured as die-cast parts with each other combined. By applying the levers to a shaft tubular semi-finished products can be used with each required length and with any required number of levers be manufactured inexpensively. The beneficial properties the new control shaft are related that die-cast parts are to be made smaller in size than it according to the aforementioned DE 197 27 853 Cl is the case. Amongst other things this makes the effort for quality assurance essential reduced.

Relativ kurze Schaltwellen, wie sie für Leistungsschalter mit normaler Polzahl und mit geringem, bis mittlerem Bemessungsstrom benötigt werden, können nach einer Ausgestaltung der Erfindung derart aufgebaut sein, daß alle Hebel durch einen zusammenhängenden Druckgußkörper gebildet sind, wobei zwischen den Hebeln den Wellenschaft mantelförmig umschließende Abschnitte des Druckgußkörpers angeordnet sind. Es kann aber zur Herstellung langer Schaltwellen günstiger sein, jeden Hebel mit beidseitig anschließenden konzentrischen Fortsätzen als Einheit auszubilden. Hierbei können zwischen den Hebeln freiliegende Abschnitte des rohrförmigen Halbzeuges vorhanden sein.Relatively short switching shafts, as used for circuit breakers normal number of poles and with low to medium rated current can be required according to an embodiment of the Invention be constructed such that all levers by one coherent die-cast body are formed, between the levers encircling the shaft shaft Sections of the die-cast body are arranged. But it can be cheaper to make long shift shafts, everyone Lever with concentric extensions adjoining on both sides to train as a unit. Here, between the levers exposed sections of the tubular semi-finished product available his.

Sollte es sich erweisen, daß durch die Aufbringung eines Druckguß-Werkstoffes auf das rohrförmige Halbzeug nicht zugleich eine Befestigung erzielt wird, die zur Übertragung der geforderten Kräfte ausreicht, so kann durch eine geeignete Aufrauhung, Profilierung oder Anordnung von Vertiefungen in dem Halbzeug der Kraftschluß verbessert werden. Mit besonders geringem Aufwand ist eine gute Verbindung dadurch zu erzielen, daß das rohrförmige Halbzeug für den Wellenschaft aus Stahl besteht und in Verbindung mit Zinkdruckguß als Werkstoff für die Hebel wenigstens außen galvanisch verzinkt ist.Should it prove that the application of a Die-casting material on the tubular semi-finished product not at the same time an attachment is achieved which is used to transmit the required forces is sufficient, can be done by a suitable Roughening, profiling or arrangement of depressions in the semi-finished product can be improved. With special A good connection can be achieved with little effort by that the tubular semi-finished product for the shaft Steel exists and in connection with die-cast zinc as a material for the levers is at least galvanized on the outside.

  • Bereitstellung eines Wellenschaftes aus einem rohrförmigen Halbzeug,
  • Bereitstellung einer geteilten Gießform für wenigstens einen der Hebel und sich beidseitig des Hebels in axialer Richtung des Halbzeuges erstreckende konzentrische Fortsätze,
  • Positionierung des Wellenschaftes in der Gießform mit dichtem Abschluß am Umfang des Wellenschaftes,
  • Einbringen eines schmelzflüssigen Druckguß-Werkstoffes in die Gießform zur Bildung des Hebels und der anschließenden, zu dem Wellenschaft konzentrischen Fortsätze,
  • Öffnen der Gießform nach angemessener Abkühlung des Druckguß-Werkstoffes und Entnahme des Wellenschaftes mit daran befestigtem, wenigstens einen Hebel und anschließende mantelförmige Abschnitte aufweisenden Druckgußkörper.
