Description
Pem sonst sehr günstigen Antrieb des im Schrägschnitt schneidenden Messers von Schneidemaschinen mittels Kurbeltriebs und Druckstange von oben steht bei der bekannten Ausführung die ungünstige Beanspruchung des Maschinengestells und der große Räderaufbau gegenüber. Die neue Erfindung beseitigt diese Mängel dadurch, daß das Zahnradvorgelege geteilt und der Kurbelzapfen für die Druckstange zwischen den den Messerträger umfassenden angetriebenen Rädern angeordnet ist. Dadurch werden die Räder nur halb so groß, die Räderlagerungen rücken entsprechend näher an das Maschinengestell heran, die Beanspruchung in den Lagcrstellen der Vorder- und Hinterwand wird gleich groß, so daß bei einem viel geringeren Aufwand an Baustoffen sich eine geringere Formänderung des Maschmenkörpers und damit ein geringerer Reibungsverlust ergibt; die Erfindung bringt also einen wesentlichen wirtschaftlichen Vorteil. In den Abbildungen ist die Erfindung dargestellt. Es zeigtPem otherwise very favorable drive of the bevel cutting knife from Cutting machines by means of a crank drive and push rod from above are available in the known Execution of the unfavorable stress on the machine frame and the large wheel structure opposite. The new invention eliminates these deficiencies in that the gear reduction is divided and the crank pin for the push rod between the driven one encompassing the knife carrier Wheels is arranged. As a result, the wheels are only half the size, the wheel bearings move closer to the machine frame, the stress in the Storage of the front and rear wall is the same size, so that with a much lower cost of building materials a there is less change in shape of the mesh body and thus less friction loss; the invention thus brings a significant economic advantage. In the pictures the invention is shown. It shows
Abb. ι die Maschine in Vorderansicht,Fig. Ι the machine in front view,
Abb. 2 einen Querschnitt durch den Antrieb in vergrößertem Maßstabe.Fig. 2 shows a cross section through the drive on an enlarged scale.
In bekannter Weise ist in dem Maschinenkörper ι der Messerträger 2 geführt. Die Auf- und Abbewegung des Messerträgers wird durch die Vermittlung einer Kurbelstange 3 von einer Riemenscheibe 4 abgeleitet.In a known manner, the knife carrier 2 is guided in the machine body ι. the The up and down movement of the knife carrier is controlled by a connecting rod 3 derived from a pulley 4.
Die Riemenscheibe 4 ist fest verbunden mit der Antriebswelle 5, auf welcher fest verkeilt die Stirnräder 6 und 7 sitzen. Diese kleinen Stirnräder 6 und 7 greifen ein in die großen Stirnräder 8 und 9, welche lose auf den im Maschinengestell 1 befestigten Bolzen 10 und 11 laufen. Durch die beiden Stirnräder 8 und 9 ist ein Bolzen 12 gesteckt, auf welchem die Kurbelstange 3 gelagert ist.The pulley 4 is firmly connected to the drive shaft 5, on which it is firmly wedged the spur gears 6 and 7 are seated. These small spur gears 6 and 7 mesh with the large ones Spur gears 8 and 9, which loosely on the bolts 10 and 11 fastened in the machine frame 1 to run. Through the two spur gears 8 and 9, a bolt 12 is inserted, on which the Connecting rod 3 is mounted.
Die Kraftübertragung erfolgt also von der Antriebswelle aus unter Beanspruchung von Vorderwand xa und Hinterwand xb durch Vermittlung zweier Zahnradpaare, zwischen denen die Kurbelstange sich bewegt. Durch diese günstige Einrichtung werden die Räder 8 und 9 klein und leicht, desgleichen die Wände xa und xb. The power transmission thus takes place from the drive shaft under stress on the front wall x a and rear wall x b by means of two pairs of gears, between which the connecting rod moves. This favorable arrangement makes the wheels 8 and 9 small and light, as do the walls x a and x b .
