Abstract
Description
Die Erfindung bezieht sich auf ein Verfahren zur Herstellung eines verzahnten, topfförmigen Getriebe teiles, bei welchem der umgebogene Randbereich eines topfförmigen Werkstückes in die Zahnnuten eines mit einer Außenverzahnung ausgerüsteten Werkzeuges zur Herstellung der Innenverzahnung eingedrückt und gleichzeitig gelängt wird.The invention relates to a method for Production of a toothed, cup-shaped gear part, in which the bent edge area of a cup-shaped workpiece in the tooth grooves of a an external toothing tool Production of the internal toothing indented and is lengthened at the same time.
Verzahnte Getriebeteile sind in großem Umfang an Achs- und Getriebewellen in der Technik im Einsatz und die Herstellung dieser bekannten verzahnten Ge triebeteile erfolgt vielfach spanabhebend. Dieses Verfahren ist sehr kostenaufwendig.Toothed gear parts are on a large scale Axle and gear shafts in use in technology and the manufacture of this well-known toothed Ge drive parts are often machined. This Procedure is very expensive.
Um das Einarbeiten von Rillen auf der Innenfläche von Hohlkörpern einfacher und kostengünstiger zu gestalten, ist ein Verfahren gemäß dem Oberbegriff des Patentanspruches aus der DE-OS 25 51 156 be kanntgeworden. Bei diesem bekannten Verfahren wird ein vorgeformter Napf kraftschlüssig auf einen rotierenden Dorn mit entsprechender Rillung aufge setzt sowie durch Druck auf den Außenmantel des Napfes unter Verringerung des Außendurchmessers und Vorwärtsstrecken der Napf dann auf den Dorn form schlüssig kalt aufgewalzt.To incorporate grooves on the inner surface of hollow bodies easier and cheaper too design is a process according to the generic term of the claim from DE-OS 25 51 156 be became known. In this known method a preformed bowl non-positively on one rotating mandrel with appropriate scoring sets as well as by pressure on the outer jacket of the Cups while reducing the outside diameter and Then stretch the bowl forward on the mandrel form finally rolled cold.
Aus der DE-37 11 927 C1 ist es bekannt, einen ro tationssymmetrisch vorgeformten Hohlkörper dadurch an der Außenseite mit in axialer Richtung verlau fenden Profilierungen zu versehen, daß die Profi lierungen nach Zustellen wenigstens einer Profil rolle mittels dieser durch Drücken erzeugt werden.From DE-37 11 927 C1 it is known to provide a ro thereby preformed hollow body symmetrically on the outside with in the axial direction fenden Profilungen that the professional after delivering at least one profile roll can be generated by pressing this.
Aus der DE-OS 28 29 041 ist ein Verfahren zur Her stellung eines innen- und außenverzahnten topfför migen Bauteiles bekanntgeworden, bei welchem ein un verzahntes topfförmiges Blechteil als Ausgangswerk stück auf einen mit einer der zu erzeugenden Innen verzahnung des Blechteiles entsprechenden Außenver zahnung versehenen Aufnahmedorn geschoben und sodann das Außenprofil auf das topfförmige Blechteil auf gewalzt wird.From DE-OS 28 29 041 is a method for Her position of an internally and externally toothed pot known component, in which an un serrated pot-shaped sheet metal part as the starting work piece on one with one of the interior to be created gearing of the sheet metal part corresponding external ver toothed mandrel pushed and then the outer profile on the pot-shaped sheet metal part is rolled.
Alle diese bekannten Verfahren gehen also von einem Napf oder einem rotationssymmetrisch vorgeformten Hohlkörper aus, wobei dieser Napf oder Hohlkörper in mehreren getrennten Arbeitsgängen auf unterschied lichen Maschinen als Bauteil hergestellt werden muß. Durch dieses Arbeitsverfahren wird eine Gefügever änderung in das Bauteil eingetragen, die insbeson dere zu einer Verhärtung der Oberfläche führt. Dies kann zu Rissen in dem Bauteil führen, die zur Un brauchbarkeit des hergestellten Zahnrades führen können.All of these known methods therefore proceed from one Cup or a rotationally symmetrical preformed Hollow body, this bowl or hollow body in several separate operations on difference Lichen machines must be manufactured as a component. Through this working process, a structure is Change entered in the component, in particular which leads to hardening of the surface. This can lead to cracks in the component that lead to Un usability of the manufactured gear can.
Der Erfindung liegt die Aufgabe zugrunde, ausgehend von dem gattungsbildenden Verfahren, dieses Verfahren so weiter zu gestalten, daß in einer Aufspannung ge arbeitet werden kann.The invention is based on the object from the generic method, this method so to design that ge in one setting can be worked.
Diese Aufgabe wird durch die im Patentanspruch angegebene Erfindung gelöst. This task will solved by the invention specified in the claim.
Mit anderen Worten ausgedrückt wird gemäß der Erfin dung vorgeschlagen, daß die Herstellung des mit einer Innen- und Außenverzahnung versehenen Getrie beteiles in einer Aufspannung erfolgt, so daß die getrennten Arbeitsgänge auf unterschiedlichen Ma schinen vermieden werden und Gefügeveränderungen, die zur Zerstörung des Werkstückes führen können, ausgeschlossen werden.In other words, according to the inven tion suggested that the manufacture of the an internal and external gear provided takes place in a setting so that the separate operations on different dimensions seem to be avoided and structural changes, which can lead to the destruction of the workpiece, be excluded.
Die Erfindung wird nachstehend anhand eines Ausführungsbeispiels beschrieben. Es zeigt The invention is illustrated below described an embodiment. It shows
Fig. 1 eine zwischen Werkzeug und Vorsetzer eingespannte Ronde, Fig. 1 is a clamped between the tool and Vorsetzer Ronde,
Fig. 2 die Endform eines gefertigten Werk stückes mit Innenverzahnung und Fig. 2 shows the final shape of a finished workpiece with internal teeth and
Fig. 3 das Stadium des Einrollens der Außen verzahnung auf die Außenseite des topfförmigen Werkstückes. Fig. 3 shows the stage of rolling the external teeth on the outside of the cup-shaped workpiece.
In den Fig. 1 bis 3 ist ein Werkzeug 2 dargestellt, das mit einer Außenverzahnung ausgerüstet ist, von der eine Zahnnut 4 erkennbar ist. Das Werkzeug 2 ar beitet mit einem Vorsetzer 3 zusammen, der an dem Werkzeug 2 ein rondenförmiges Werkstück 1 fest klemmt.In FIGS. 1 to 3, a tool 2 is illustrated that is equipped with an external toothing, is detectable by a tooth groove. 4 The tool 2 ar works together with a step-up 3 , which clamps a circular-shaped workpiece 1 firmly on the tool 2 .
Von der Außenverzahnung ist eine Zahnnut 4 erkennbar und diese vorstehend beschriebene Einheit rotiert und wird von einer in der Zeichnung nicht darge stellten Druckrolle beaufschlagt, die nunmehr - wie dies in Fig. 2 dargestellt ist - das rondenförmige Werkstück 1 zu einem topfförmigen Werkstück umge formt hat, das mit einer Innenverzahnung ausgerüstet ist, die sich in die Zahnnuten 4 des Werkzeuges 2 eingelegt hat.From the external toothing, a tooth groove 4 can be seen and this unit described above rotates and is acted upon by a pressure roller, not shown in the drawing, which - as shown in FIG. 2 - has now shaped the circular-shaped workpiece 1 into a pot-shaped workpiece , which is equipped with an internal toothing that has been inserted into the tooth grooves 4 of the tool 2 .
In einem letzten Arbeitsgang wird dann - wie dies Fig. 3 darstellt - an das so geformte topfförmige Werkstück ein zahnradförmiges Werkzeug 5 angesetzt, das auf die Außenseite des in Fig. 3 erkennbaren Topfes die Außenverzahnung eindrückt.In a last step - as shown in FIG. 3 - a gear-shaped tool 5 is then attached to the cup-shaped workpiece, which presses the external toothing onto the outside of the pot shown in FIG. 3.
