Description

Schlitten 58 befestigt, der von einem üblichen Hydraulikantrieb getragen und betätigt wird.Fastened carriage 58, which is carried and operated by a conventional hydraulic drive.

Ausfahrbare Führungssäulen 65 sorgen für die Stabilität der Bewegung des Schlittens. Die Führungssäulen 65 sind in Zylinderführungen 67 gleitend gelagert, die am Bett 44 befestigt sind.Extendable guide columns 65 ensure the stability of the movement of the carriage. The guide columns 65 are slidably mounted in cylinder guides 67, attached to bed 44.

Die Hauptaufgabe des Schlittens ist es, mehrere Elektroden zwischen den Wellenenden 42 und 43 zum Abschrägen der Nuten 32 einzuführen. Die Elektroden 81 sind an Gewindebolzen 78 befestigt, die durch Drehen eines Einstellrades 79 axial einstellbar sind.The main task of the slide is to position several electrodes between the shaft ends 42 and 43 Introduce chamfering of the grooves 32. The electrodes 81 are attached to threaded bolts 78, which through Rotating an adjusting wheel 79 are axially adjustable.

Zur Synchronisation des Antriebs von Walzen und Elektroden sind Zahnstangen 82 mittels Schrauben 83 an einem mit dem Schütten 58 aus einem Stück geformten Gehäuse 84 fest angebracht. Ritzel 85 sind an Stützen 86 drehbar gelagert, die an benachbarten Wellenenden starr befestigt sind.To synchronize the drive of rollers and Electrodes are racks 82 by means of screws 83 on one with the chute 58 in one piece molded housing 84 fixedly attached. Pinions 85 are rotatably mounted on supports 86, which on adjacent Shaft ends are rigidly attached.

Die vertikale Bewegung des Schlittens und damit der Zahnstange 82 wird durch das Ritzel 85 in eine Drehbewegung umgewandelt und auf Zahnringe 87 und 88 und von diesen auf die Wellenenden 42 und 43 übertragen. Die Zahnstangen 82 werden mit den Ritzeln 85 während deren vertikaler Bewegung durch Führungsräder 89 in Eingriff gehalten, die an der Stütze 86 drehbar gelagert sind, die auch die Ritzel 85 tragen. ·The vertical movement of the carriage and thus the rack 82 is made by the pinion 85 in a Rotary movement converted and on toothed rings 87 and 88 and from these on the shaft ends 42 and 43 transfer. The racks 82 are with the pinions 85 during their vertical movement by guide wheels 89 held in engagement, which are rotatably mounted on the support 86, which also carry the pinions 85. ·

Fi g. 6 zeigt einen Ausschnitt des Zahnringantriebes. Der Zahnring 88 ist so ausgeführt, daß er gleitend über das Wellenende 42 an dessen Umfang 28 aufgenommen werden kann, und ein gespaltener Spannring 90 ist auf ähnliche Weise über das Wellenende 42 geschoben und liegt an der Stirnseite 91 des Zahnringes 88 an. Der Spannring 90 kann an Flächen 92 und 93 getrennt werden und daher um die Oberfläche 28 herum leicht ausgeweitet werden. Wenn der Zahnring 88 und der Spannring 90 anliegen, wird der Spannring 90 an dem Zahnring 88 durch mehrere Schrauben 94 befestigt.Fi g. 6 shows a section of the toothed ring drive. The toothed ring 88 is designed so that it is received in a sliding manner over the shaft end 42 on the circumference 28 thereof can be, and a split clamping ring 90 is slid over the shaft end 42 and in a similar manner rests on the end face 91 of the toothed ring 88. The clamping ring 90 can be separated at surfaces 92 and 93 and therefore are slightly expanded around the surface 28. When the ring gear 88 and the If the clamping ring 90 are in contact, the clamping ring 90 is fastened to the toothed ring 88 by a plurality of screws 94.

Schließlich wird die zusammengebaute, aus dem Spannring und dem Zahnring bestehende Einheit am Wellenende 42 befestigt, indem der Spannring um die Oberfläche 28 herum zusammengezogen wird. Dieses Zusammenziehen erfolgt durch ein Anziehen von Schrauben 95 und 96, wodurch sich der Spalt zwischen den Flächen 92 und 93 schließt. Die Schrauben 95 und % können mittels eines normalen Schraubenziehers oder eines ähnlich anwendbaren Schlüssels durch die Öffnungen 97 und 98 verstellt werden. Durch diese Ausbildung eines leicht annehmbaren Zahnringantriebes bleiben die Wellenenden 42 und 43 unberührt und die Maschineneinstellzeit wird beträchtlich verringert.Finally, the assembled unit consisting of the clamping ring and the toothed ring is attached to the Shaft end 42 is secured by pulling the clamping ring together around surface 28. This Contraction is done by tightening screws 95 and 96, thereby increasing the gap between the surfaces 92 and 93 closes. The screws 95 and% can be removed using a normal screwdriver or a similarly applicable key can be adjusted through the openings 97 and 98. Through this Formation of an easily acceptable toothed ring drive, the shaft ends 42 and 43 remain untouched and the machine set-up time is considerably reduced.

Die Walzen sind in an sich bekannter Weise in der Vorrichtung in einem Tank liegend angeordnet, der am Bett 44 gelagert ist. Der Tank weist Längsseiten und Stirnwände 101 auf. Die Stirnwände 101 haben Wellenöffnungen, die den Durchtritt der Wellenenden zu Stellen außerhalb des Tanks ermöglichen, an denen die Lagerung und der Antrieb leichter durchgeführt werden können.The rollers are arranged in a manner known per se in the device in a tank lying on the Bed 44 is stored. The tank has long sides and end walls 101. The end walls 101 have Shaft openings that allow the shaft ends to pass through to locations outside the tank where the storage and the drive can be carried out more easily.

Um einen ständigen Vorrat an Arbeitsflüssigkeit sicherzustellen, muß eine Dichtung um die Wellenenden 42 und 43 herum angebracht werden. Diese Dichtung hat die Form eines Ringes 103 mit achteckigem äußerem Umfang 104 und einem kreisförmigen Innenumfang 105. Der achteckige Umfang 104 ist mit Radialnuten 106 zur Befestigung des Ringes 103 an der Stirnwand 101 versehen. Die Wellenöffnung in der Stirnwand 101 hat eine Gestalt, die dem achteckigen äußeren Umfang des Ringes 103 entspricht.To ensure a constant supply of working fluid, a seal must be provided around the shaft ends 42 and 43 around. This seal has the shape of a ring 103 with an octagonal outer circumference 104 and a circular inner circumference 105. The octagonal circumference 104 is with Radial grooves 106 are provided for fastening the ring 103 to the end wall 101. The shaft opening in the End wall 101 has a shape that corresponds to the octagonal outer circumference of ring 103.

Die Dichtungsringe 103 sind an der Stirnwand 101 an mehreren Stellen befestigt. Um ein wirksame Abdichtung zwischen der Stirnwand 101 und den umlaufenden Wellenenden 42 und 43 zu schaffen, ist ein O-Ring 110 an der Innenfläche der Dichtung 103 eingesetzt.The sealing rings 103 are attached to the end wall 101 at several locations. To make an effective seal An O-ring 110 is to be created between the end wall 101 and the circumferential shaft ends 42 and 43 inserted on the inner surface of the seal 103.
