Description
Es sind schon Kettensägemaschinen bekannt, die mit einer Vorrichtung zum Antrieb einer biegsamen Welle ausgerüstet sind, um z. B. eine Schleifscheibe oder einen Bohrer antreiben zu können. Bei diesen bekannten Vorrichtungen erfolgt der Antrieb der biegsamen Welle unmittelbar von der Motorwelle aus, die mit entsprechenden Kupplungsvorrichtungen versehen ist, um die biegsame Welle an sie anschließen zu können. Mit diesem unmittelbaren Antrieb ist jedoch der Nachteil verbunden, daß die biegsame Welle nur die Drehzahl des Motors besitzt, die für viele Zwecke zu .niedrig ist. Den gleichen Nachteil einer zu niedrigen Drehzahl des von der biegsamen Welle angetriebenen Werkzeugs hat eine andere bekannte Vorrichtung, bei welcher die biegsame Welle über eine auf der Motorwelle sitzende Schnecke angetrieben wird.There are already chain saws known with a device for driving a flexible shaft are equipped to, for. B. a grinding wheel or a drill to be able to drive. In these known devices, the flexible ones are driven Shaft directly from the motor shaft with the appropriate coupling devices is provided in order to be able to connect the flexible shaft to them. With this immediate drive, however, is the Disadvantage connected that the flexible shaft has only the speed of the motor, which for many purposes too .low. The same disadvantage of a too low speed of the the flexible shaft driven tool has another known device, in which the flexible shaft is driven by a worm seated on the motor shaft will.
Demgegenüber besteht die Erfindung darin, daß für den Anschluß der biegsamen Welle eine Hilfswelle vorgesehen ist, die von einem am Maschinengehäuse drehbar gelagerten Arm getragen und von der Hauptwelle mittels eines Riementriebs o. dgl. angetrieben wird. Diese Vorrichtung kann mit wenigen Griffen gebrauchsfertig gemacht und jederzeit nachgestellt bzw. abgenommen werden. Gleichzeitig gestattet sie, den Motor der Kettensägemaschine bei ausgerückter Sägewelle auch für andere anfallende Arbeiten auszunützen. In contrast, the invention consists in that for the connection of the flexible shaft an auxiliary shaft is provided which is rotatably supported by a shaft on the machine housing Arm carried and driven by the main shaft by means of a belt drive or the like. This device can be made ready for use in a few simple steps and readjusted at any time or be removed. At the same time, it allows the chain saw machine to run Can also be used for other work when the saw shaft is disengaged.
Die Erfindung ist in den Zeichnungen in beispielsweiser Ausführungsform dargestellt, und zwar zeigt:The invention is shown in the drawings in an exemplary embodiment, namely shows:
Abb. ι eine Seitenansicht, Abb. 2 eine Draufsicht der ganzen Maschine, Fig. Ι a side view, Fig. 2 a plan view of the entire machine,
Abb. 3 einen Schnitt durch die Antriebsvorrichtung allein in größerem Maßstab.Fig. 3 shows a section through the drive device alone on a larger scale.
α ist das Getriebegehäuse der Maschine, aus dem ein Stirnzapfen b der Kurbelwelle herausragt, auf dem eine Riemenscheibe c sitzt. An dem Gehäuses ist ein Auge d vorgesehen, das zum Durchstecken eines Schraubenbolzens e (Abb. 3) dient. Auf dem Bolzen e sitzt eine Knebelmutter f zum Festspannen eines Armes g, der bei gelöster Mutter / um den Bolzen e verschwenkbar ist. Das freie Ende des Armes g trägt eine Hülse h, in welcher die mit einer Laufbuchse i versehene Antriebsspindel k einer biegsamen Welle 0 zwischen Kugellagern m gelagert ist. Außerdem dient die Hülset zum Aufstecken der Anschlußmuffe η der mit einem Handstück p versehenen biegsamen Welle o. Die Welle 0 treibt z. B. eine Schleifscheibe q zum Schärfen der Sägekette r und wird selbst von der Riemenscheibe c auf der Motorwelle b mittels eines Riemens ί und einer auf der Spindel k sitzenden Riemenscheibe* angetrieben. Die Verschwenkbarkeit des Arms g um den Bolzen e ermöglicht ein einfaches Nachspannen des Treibriemens s. α is the gearbox of the machine, from which a spur b of the crankshaft protrudes, on which a belt pulley c is seated. An eye d is provided on the housing, which is used to insert a screw bolt e (Fig. 3). A toggle nut f sits on the bolt e for tightening an arm g which, when the nut is loosened, can be pivoted about the bolt e. The free end of the arm g carries a sleeve h in which the drive spindle k , which is provided with a bushing i , of a flexible shaft 0 is mounted between ball bearings m. In addition, the sleeve set is used to attach the connecting sleeve η of the flexible shaft o provided with a handpiece p . The shaft 0 drives z. B. a grinding wheel q for sharpening the saw chain r and is itself driven by the pulley c on the motor shaft b by means of a belt ί and a pulley * seated on the spindle k. The pivotability of the arm g about the bolt e enables easy retensioning of the drive belt s.
