Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Bearbeiten von gerad verzahnten Kegelrädern nach dem Oberbegriff des Anspruchs 1.The invention relates to a device for machining straight toothed bevel gears according to the preamble of claim 1.
Aus der US-PS 24 48 426 ist eine derartige, nach dem sogenannten "Revacycle"-Verfahren arbeitende Vorrichtung bekannt, die ein Werkzeug ver wendet, das mit einem Drehantrieb versehen ist und profilierte Schneiden aufweist. Hierbei ist ferner ein Schlitten vorgesehen, der einen gegenüber diesem schwenkbaren Teilapparat trägt, der das zu bearbeitende Kegelrad mit dessen Achse parallel zur Radialebene des Werkzeuges aufnimmt und parallel zu einem Durchmesser des Werkzeugs verfahrbar ist. Außerdem ist eine Ein richtung zur Vornahme einer relativen Zustellbewegung zwischen Kegelrad und Werkzeug in Achsrichtung des Werkzeuges vorgesehen. Die profilierten Schneiden des Werkzeugs sind an dessen Außenumfang nach außen gerichtet an geordnet und besitzen unterschiedliche Profilform, so daß sie aufwendig in der Herstellung ebenso wie in der Einstellung sind. Bei einem Werkzeug mit außenliegenden Schneiden ist zur Erzeugung von Längsballigkeit der Zahn flanken immer eine Kombination von einer oder mehreren Bewegungen oder die Verbindung mit korrigierten Schneiden erforderlich.From US-PS 24 48 426 is such, according to the so-called "Revacycle" method working device known that ver a tool turns, which is provided with a rotary drive and profiled cutting edges having. In this case, a carriage is also provided, one opposite this pivoting dividing device, which carries the bevel gear to be machined whose axis is parallel to the radial plane of the tool and parallel can be moved to a diameter of the tool. In addition, is an direction for making a relative feed movement between bevel gear and Tool provided in the axial direction of the tool. The profiled Cutting edges of the tool face outwards on its outer circumference ordered and have different profile shape, so that they are expensive in the manufacture as well as the attitude. With a tool with external cutting is used to produce longitudinal crowning of the tooth always flank a combination of one or more movements or the Connection with corrected cutting edges required.
Zum "Revacycle"-Verfahren ist in dem DE-Buch "Handbuch der Verzahn technik", VEB-Verlag Technik, Berlin 1973, S. 232 und 233, ausgeführt, daß sich hiermit beliebige ballige Zahnflanken durch entsprechende Werkzeugaus bildung herstellen lassen, daß die Werkzeuge jedoch sehr teuer sind, da Form und Lage der Schneidkanten den Flankenflächen entsprechen.For the "Revacycle" process is in the DE book "manual the tooth technik ", VEB-Verlag Technik, Berlin 1973, pp. 232 and 233, explained that any spherical tooth flanks with appropriate tools Have education made, but the tools are very expensive because of the shape and position of the cutting edges correspond to the flank surfaces.
Aufgabe der Erfindung ist es daher, eine Vorrichtung nach dem Ober begriff des Anspruchs 1 zu schaffen, die es ermöglicht, ballige Zahnkanten ohne gesteuerte Bewegungen und ohne speziell ausgelegte Schneidenformen der Werkzeuge zu erzeugen.The object of the invention is therefore a device according to the Ober Concept of claim 1 to create, which enables crowned tooth edges without controlled movements and without specially designed cutting edge shapes Generating tools.
Diese Aufgabe wird entsprechend dem kennzeichnenden Teil des An spruchs 1 gelöst.This task is performed according to the characteristic part of the To spell 1 solved.
Hierdurch wird erreicht, daß die Herstellung balliger Zahnkanten keine gesteuerten Bewegungen und das Werkzeug nur Schneiden mit gleicher Profilform erfordert, die das Kegelrad bogenförmig berühren, so daß die Zahnflanken ballig und die Zahnlücken am kleinen und großen Durchmesser des Kegel rads breiter als im dazwischenliegenden Bereich geschnitten werden.This ensures that the production of spherical tooth edges no controlled movements and the tool only cutting with the same Profile shape requires that the bevel gear touch arcuate, so that the Tooth flanks crowned and the tooth gaps on the small and large diameter of the cone rads are cut wider than in the area in between.
Weitere Ausgestaltungen der Erfindung sind der nachfolgenden Beschreibung und den Unteransprüchen zu entnehmen.Further refinements of the invention are as follows Description and the dependent claims.
Die Erfindung wird nachstehend anhand eines in den beigefüg ten Abbildungen dargestellten Ausführungsbeispiels näher erläutert.The invention is described below with reference to one of the following illustrated embodiment illustrated in more detail.
Fig. 1 zeigt schematisch teilweise im Schnitt eine Vorrich tung zum Bearbeiten von geradverzahnten Kegelrädern. Fig. 1 shows schematically partially in section a Vorrich device for machining straight bevel gears.
Fig. 2 zeigt ausschnittweise eine Draufsicht auf die Vorrich tung von Fig. 1. Fig. 2 shows a detail of a plan view of the Vorrich device of Fig. 1st
Die dargestellte Vorrichtung umfaßt ein Gehäuse 1, an dessen Oberseite ein glockenförmiger Grundkörper 2 um seine Achse drehbar ge lagert ist. An der Unterseite des Grundkörpers 1 befindet sich ein Zahnrad 3, das mit einem Ritzel 4 in Eingriff steht, das seinerseits von einem Motor 5 antreibbar ist, um den Grundkörper 2 um seine Achse zu drehen.The device shown comprises a housing 1 , on the top of which a bell-shaped base body 2 is rotatably supported about its axis. On the underside of the base body 1 there is a gearwheel 3 , which meshes with a pinion 4 , which in turn can be driven by a motor 5 in order to rotate the base body 2 about its axis.
Der Grundkörper 2 nimmt in einer Radialebene benachbart zu seiner Oberkante einwärts gerichtete Schneiden 6 auf. Die Schneiden 6 können gleichbleibend (Fräswerkzeug) oder nach innen ansteigend (Räum werkzeug) ausgebildet sein.The base body 2 receives cutting edges 6 directed inwards in a radial plane adjacent to its upper edge. The cutting edges 6 can be made constant (milling tool) or rising inwards (broaching tool).
Die Vorrichtung umfaßt ferner einen Schlitten 7, der längs einer Führung 8 in einer Richtung parallel zu einem Durchmesser des Grundkörpers 2 verschiebbar ist. Der Schlitten 7 trägt einen gegenüber diesem um eine Achse 9 schwenkbaren Teilapparat 10, der ein zu bear beitendes Kegelrad 11 mit dessen Achse 12 parallel zu der Radialebene des Grundkörpers 2 aufnimmt und nach der jeweiligen Bearbeitung einer Zahnlücke das Kegelrad 11 um eine Teilung zur Bearbeitung der nächsten Zahnlücke weiterschaltet.The device further comprises a carriage 7 , which is displaceable along a guide 8 in a direction parallel to a diameter of the base body 2 . The carriage 7 carries a pivotable relative to this about an axis 9 sub-apparatus 10 , which receives a bevel gear 11 to be machined with its axis 12 parallel to the radial plane of the base body 2 and, after the respective machining of a tooth gap, the bevel gear 11 by one division for machining the next tooth gap.
Das Gehäuse 1 ist längs einer Führung 13 in Axialrichtung zum Grundkörper 2 und damit in Richtung auf den Schlitten 7 in Arbeitspo sition zum Kegelrad 11 zustellbar. Durch Drehen des Teilapparats 10 um seine Achse 9 erfolgt die Positionierung des Kegelrades 11 derart, daß das Werkzeug mit dem Kegelrad 11 bogenförmig in Eingriff gelangt, d. h. daß die Mantellinie des Kegelrades 11 praktisch senkrecht zum Durch messer des Grundkörpers 2 verläuft. Die Zahntiefenzustellung erfolgt über ein Verfahren des Schlittens 7 längs seiner Führung 8.The housing 1 is along a guide 13 in the axial direction to the base body 2 and thus in the direction of the carriage 7 in the working position to the bevel gear 11 deliverable. By rotating the sub-assembly 10 about its axis 9 , the bevel gear 11 is positioned such that the tool engages in an arc shape with the bevel gear 11 , ie the surface line of the bevel gear 11 is practically perpendicular to the diameter of the base body 2 . The tooth depth is adjusted by moving the carriage 7 along its guide 8 .
