Vorrichtung zum spanlosen Abschrägen der Stirnkanten von vorverzahnten ZahnrädernDevice for non-cutting bevelling of the front edges of pre-toothed gears

Die Erfindung betrifft eine Vorrichtung zum spanlosen Abschrägen bzw. Brechen der Stirnkanten von vorverzahnten Zahnrädern mit einem radial gegen das zu bearbeitende Werkrad andrückbaren Leitzahnrad, dessen Zahnbreite kleiner ist als die des Werkrades und mit zu beiden Seiten des Leitzahnrades stumpf an die Stirnseiten der Zähne des Leitzahnrades anstoßenden und mit diesem drehfest verbundenen Stirnkantenwälzrädern, nach Patentanmeldung P 20 22 937.2.The invention relates to a device for non-cutting bevelling or breaking of the front edges of pre-toothed Gear wheels with a guide gear wheel which can be pressed radially against the work wheel to be machined and whose tooth width is smaller than that of the work wheel and with on both sides of the guide gear butt on the faces of the teeth of the guide gear abutting and non-rotatably connected to this spur edge generating wheels, according to patent application P 20 22 937.2.

Bei der bekannten Vorrichtung ist das Leitrad zugleich als Glättrad für die Zahnflanken des Werkrades ausgebildet. Dies erfordert eine sehr genaue Übereinstimmung der stumpf aneinanderliegenden Stirnprofile des Leitrades und der beiden Stirnkantenwalzräder, damit beim spanlosen Kantenbrechen keine Anstauchung der Werkradflanken eintritt. Die genaue Bearbeitung verursacht erhöhte Werkzeugkosten.In the known device, the stator is at the same time designed as a smoothing wheel for the tooth flanks of the work wheel. This requires a very precise match of the blunt Adjacent end profiles of the guide wheel and the two end edge rolling wheels, so that during chipless edge breaking no upsetting of the work wheel flanks occurs. Precise machining causes increased tool costs.

Die Erfindung bezweckt eine Verringerung der Werkzeugkosten, indem die Bildung eines geringen Materialaufwurfes an den Flanken der Werkräder beim Brechen der Kanten zugelassen wird. Die Erfindung besteht darin, daß außer dem Leitrad ein weiteres, mit dem Werkrad im Eingriff befindliches . Zahnrad vorhanden ist, dessen Zahnbreite mindestens gleich der Zahnbreite des Werkrades ist und welches als Glättrad ausgebildet ist.The aim of the invention is to reduce the tool costs by creating a low material build-up on the flanks of the work wheels when breaking the edges. The invention consists in that in addition to the stator another one in mesh with the work wheel. There is a gear whose face width is at least equal is the face width of the work wheel and which is designed as a smoothing wheel.

Die beanspruchte Maßnahme hat die Wirkung, daß die Zahnflanken des Werkrades einschließlich evtl. vorhandener, durch das Kantenbrechen entstandener Materialaufwürfe, geglättet werden. Durch Anordnung des Glättzahnrades diametral gegenüber dem Leitzahnrad wird außerdem die Lagerung des Werkzahnrades von Zahnkräften entlastet.The claimed measure has the effect that the tooth flanks of the work wheel including any material bulges caused by the edge breaking, smoothed will. By arranging the smoothing gear diametrically opposite the guide gear, the storage of the work gear is also relieved of tooth forces.

Die Zeichnung gibt ein Äusführungsbeispiel der Erfindung wieder und zeigt einen teilweisen Längsschnitt durch die Vorrichtung. .The drawing shows an embodiment of the invention and shows a partial longitudinal section through the device. .

In Fig. 1 ist 1 eine Grundplatte. Diese trägt als Lager 2 zur Aufnahme der Antriebswelle 3 und des Spannfutters 4 für das Glättzahnrad 5. Dieses ist mittels einer Spannschraube 6 auf dem Spannfutter undrehbar aufgespannt. In einer Gleitbahn 7 der Grundplatte sind zwei Schlitten 8 und 9 verschiebbar gelagert. Der eine Schlitten 8 trägt drehbar das.zu bear-In Fig. 1, 1 is a base plate. This carries as bearing 2 for receiving the drive shaft 3 and the chuck 4 for the smoothing gear 5. This is by means of a clamping screw 6 Clamped so that it cannot rotate on the chuck. Two carriages 8 and 9 are displaceable in a slideway 7 of the base plate stored. One carriage 8 rotatably carries the.

beitende Zahnrad 10. Auf dem zweiten Schlitten 9 ist der aus Leitrad 11 und den beiden seitlichen Abkanträdern 12 und 13 bestehende Räderblock frei drehbar gelagert. Der Schlitten 9 ist mit einem Hydraulikmotor 14 verbunden.The working gear 10 is on the second slide 9, which consists of the guide wheel 11 and the two lateral bending wheels 12 and 13 existing wheel block freely rotatably mounted. The slide 9 is connected to a hydraulic motor 14.

Die zwei Räder 5 und 10 und der Räderblock 11/13 sind radial miteinander fluchtend angeordnet. Das Glättrad 5 wird über die Welle 3 motorisch angetrieben. Das mit dem Rad 5 kämmende Werkrad 10 wird von dem Rad 5 mitgenommen. Dieses treibt wiederum den Räderblock 11/13 an.The two wheels 5 and 10 and the wheel block 11/13 are arranged radially in alignment with one another. The smoothing wheel 5 is driven by a motor via shaft 3. The work wheel 10 meshing with the wheel 5 is carried along by the wheel 5. This in turn drives the wheel block 11/13.

Durch Beaufschlagung des Hydraulikmotors wird das Werkrad durch den Räderblock gegen das Glättrad 5 gedrückt. Zunächst werden die Stirnkanten der Zahnflanken des Werkrades abgeschrägt. Bei verstärktem Druck durch den Hydraulikmotor legt sich der Schlitten 8 gegen einen nicht gezeichneten Anschlag am Hydraulikmotor und die Zahnflanken des Werkrades werden durch das Zahnrad 5 geglättet. Der Anschlag wird so eingestellt, daß die Zähne des Werkrades auf die gewünschte Dicke bearbeitet werden.When the hydraulic motor is applied, the work wheel is pressed against the smoothing wheel 5 by the wheel block. First the front edges of the tooth flanks of the work gear are bevelled. With increased pressure from the hydraulic motor the carriage 8 rests against a stop (not shown) on the hydraulic motor and the tooth flanks of the work wheel are smoothed by the gear 5. The stop is adjusted so that the teeth of the work wheel are on the desired Thickness to be machined.
