Abstract

Production of periodic structures, preferably toothed wheels and toothed arrangements, on cylindrical rotationally symmetrical components comprises metal-cutting machining carried out by a succession of the tooth-producing processes of hob peeling and shaving without tool exchange in one machine. An independent claim is also included for a device used for carrying out the process comprising at least one peeling wheel for hob peeling and at least one shaving wheel for shaving arranged on one shaft.

Description

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur spanenden Bearbeitung von zylindrischen, rotationssymetrischen Bauteilen zur Herstellung periodischer Strukturen, vorzugsweise Zahnräder und Verzahnungen, nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a method and a device for machining cylindrical, rotationally symmetrical components for the production of periodic structures, preferably gears and gears, according to the preamble of claim 1.

Stand der TechnikState of the art

Es existieren unterschiedliche Verfahren zur Herstellung von Zahnrädern, die sich auf Grund ihrer Kinematik und Zerspanungsprinzipien zum Teil erheblich voneinander unterscheiden.There are different procedures for the production of gears, which due to their kinematics and machining principles Partially differ from each other.

Üblicherweise erfolgt aufgrund der hohen Anforderungen an die Genauigkeit zunächst eine spanende Vorbearbeitung und im Anschluss eine Feinbearbeitung der Verzahnung. Aufgrund der besseren Bearbeitbarkeit wird oftmals angestrebt, die Verzahnung vor dem Härten im weichen Zustand zu bearbeiten.Usually Because of the high demands on the accuracy, there is first a cutting Pre-processing and then fine machining of the toothing. Because of the better machinability, the gearing is often sought before hardening to work in the soft state.

Das derzeit dominierende Verfahren zur Vorbearbeitung von Zahnrädern ist das Wälzfräsen. Derartige Verfahren sind u.a. in der DE19918289 „Verfahren zum Herstellen verzahnter Werkstücke", EP0614406 „Zahnradwälzfräsmaschine" oder DE4029671 „Verfahren zur Herstellung von runden Werkstücken mit stegförmigen Vorsprüngen, insbesondere zur Herstellung von Zahnrädern „ offenbart.The currently dominant process for pre-machining gears is hobbing. such Procedures include in DE19918289 "Method for manufacturing toothed workpieces ", EP0614406" gear hobbing machine "or DE4029671" method for the production of round workpieces with web-shaped projections, in particular for the production of gears "disclosed.

Zur Weichfeinbearbeitung kommt in den meisten Fällen das Schaben zum Einsatz, wie es u.a. aus der DE 19920323 „Verfahren und Maschine zum Feinbearbeiten der Zahnflanken von verzahnten Werkstücken" bekannt sind.In most cases, scraping is used for soft fine machining, as is known from the DE 19920323 "Method and machine for finishing the tooth flanks of toothed workpieces" are known.

Aufgrund der sehr unterschiedlichen Kinematik der beiden Prozesse Wälzfräsen und Schaben, müssen hierfür zwei unterschiedliche Maschinen eingesetzt werden.Because of the very different Kinematics of the two processes hobbing and Scraping, must therefor two different machines can be used.

Die Vor- und Feinbearbeitung von Zahnrädern auf zwei unterschiedlichen Maschinen führt zu einem hohen logistischen Aufwand. Dabei entstehen Kosten für den Transport des Werkstücks von einer Maschine zur nächsten, das Beladen der Maschinen und die mögliche Lagerung der Werkstücke zwischen den beiden Bearbeitungsschritten.The pre and finishing of gears on two different machines leads to a high logistic Expenditure. This incurs costs for the transport of the workpiece from one machine to the next, the loading of the machines and the possible storage of the workpieces between the two processing steps.

Um dieses Problem zu vermeiden, wird in neuerer Zeit auch das Wälzfräsen zur Weichfeinbearbeitung mit deutlich verringerten Vorschüben eingesetzt, wobei jedoch Nachteile in Bezug auf die Bearbeitungszeit in Kauf genommen werden, da die Anzahl an aktiven Schneiden und die aktive Schneidenlänge deutlich geringer ist als beim Schaben.To avoid this problem more recently hobbing for Soft fine machining with significantly reduced feed rates, however, disadvantages in terms of processing time in purchase because the number of active cutting edges and the active one cutting length is significantly less than with scraping.

Das Wälzschälen ist ein seit langer Zeit bekanntes Bearbeitungsverfahren zur Vorbereitung von Zahnrädern, das in der Vergangenheit jedoch nicht erfolgreich eingesetzt werden konnte. Wälzschälverfahren werden u.a. in der DE3533064 „Verfahren zur Bearbeitung der Flanken von Zahnrädern durch Wälzschälen sowie Vorrichtung zur Durchführung eines solchen Verfahrens", DE8607328 „Maschine zum Wälzschälen zylindrischer Verzahnungen", DE69303704 „Verfahren und Vorrichtung zum Wälzschälen" beschrieben.Skiving is a long time ago known machining process for preparing gears, the not successfully used in the past could. hob peeling are among others in DE3533064 "Method for machining the flanks of gear wheels by skiving and Implementation device such a process, " DE8607328 "Machine for Skiving more cylindrical Gears ", DE69303704" Method and device for skiving peeling ".

Innovationen im Bereich der Werkzeugmaschinensteuerungen führen dazu, dass in letzter Zeit die Anwendung dieses Prozesses zur wirtschaftlichen Vorverzahnung möglich erscheint.Innovations in the field of machine tool controls to lead that lately the application of this process to economic Pre-toothing possible appears.

Die Bearbeitungskinematik des Wälzschälens und des Schabens sind sehr ähnlich, wodurch eine Fertigbearbeitung von Zahnrädern durch Wälzschälen und Schaben in einer Maschine realisierbar ist.The machining kinematics of skiving and of cockroaches are very similar thus finishing gearwheels by skiving and Scraping is feasible in one machine.

Der Erfindung liegt die Aufgabe zugrunde, ein Bearbeitungsverfahren und eine Vorrichtung zur Herstellung von Zahnrädern oder periodischen Strukturen auf rotationssymetrischen Körpern zu entwickeln, das eine Vor- und Feinbearbeitung ohne Werkstückwechsel in einer Maschine bei hoher Bearbeitungsgeschwindigkeit realisiert.The invention is based on the object Machining method and a device for the production of gears or periodic structures on rotationally symmetrical bodies develop a pre- and fine machining without changing the workpiece realized in a machine at high processing speed.

Diese Aufgabe wird in Verbindung mit dem Oberbegriff des Patentanspruchs 1 erfindungsgemäß durch die kennzeichnenden Merkmale des Patentanspruchs 1 gelöst.This task is linked with the preamble of claim 1 according to the invention the characterizing features of claim 1 solved.

Das erfindungsgemäße Verfahren und die erfindungsgemäße Vorrichtung erlauben eine Reduzierung der Fertigungskosten von Zahnrädern. Außerdem wird eine einfachere Werkstücklogistik ermöglicht sowie verkürzte Maschinenrüstzeiten.The method according to the invention and the device according to the invention allow a reduction in the manufacturing costs of gears. Besides, will simpler workpiece logistics allows as well as shortened Machine set-up.
