Abstract
Description
Sägesaw
Die Erfindung betrifft eine Säge mit umlaufender Sägebandkette, die Sägezähne aufweist und bei der die Sügebandkette zumindest in ihrem Basisbereich zwischen zwei Schneidenwänden geführt ist ( nach Patentanmeldung P 26 60 077. ) Bei der Operationssäge nach der Hauptanmeldung wird die Sagebandkette zwischen zwei Schneidenwünden geführt, um die Sögebandkette zierlich gestalten zu können und sie gerade ohne Oszlationen fuhren zu können. Es bereitet keine Schwierigkeiten, soweit einzusägen, als die Entfernung zwischen der Spitze des Sägezahnes und dem Außenumfang der Schneidenwand entspricht. Dann aber sitzt die Schneidenwand auf dem Knochen oder derglei chen auf.The invention relates to a saw with a revolving band saw chain that Has saw teeth and in which the Sügebandkette at least in its base area is guided between two cutting edge walls (according to patent application P 26 60 077.) In the case of the surgical saw after the main registration, the saw band chain is between two Cutting edges led to make the Sögebandkette dainty and they just to be able to drive without oscillations. It's no problem so far than the distance between the tip of the saw tooth and the outer circumference corresponds to the cutting edge wall. But then the cutting wall sits on the bone or the like.
Aufgabe der Erfindung ist es, die zarge nach der Hauptanmeldung so auszubilden, daß man auf billige Weise auch tiefer sagen kann, ohne die zierliche und schmale Bauweise aufgeben zu müssen, wesentlich an Antriebsleistung opfern zu müssen oder sonstige Nachteile in Kauf nehmen zu müssen.The object of the invention is to provide the frame according to the main application to train that one can also say deeper cheaply without the delicate one and having to give up the narrow design, sacrifices significantly in terms of drive power have to or have to accept other disadvantages.
Erfindungsgemaß wird diese Aufgabe dadurch gelöst, daß periodisch ein Sägezahn Ober die lichte linke Breite der Schneidenwand und ein mindestens mittelbar darauf folgender Sägezahn Ober die lichte rechte Breite der Schneidenwand hinausragt.According to the invention this object is achieved in that periodically one saw tooth above the clear left width of the cutting edge wall and one at least indirectly The following saw tooth protrudes above the clear right width of the cutting edge wall.
Zur Breite der Schneidenwand zahlen auch eventuell Ober sie hinausstehende Nieten, Ausbuchtungen oder dergleichen.Any protruding parts may also be added to the width of the cutting wall Rivets, bulges or the like.
Durch die Merkmale des Anspruchs 2 verhindert man, daß in der Mitte ein Grat stehenbleibt. Trotzdem können die Sagezahne sehr schmal bleiben. Die anfallenden Späne bleiben sehr klein. Die Antriebsleistung wird minimalisiert. Es sei darauf hingewiesen, daß innerhalb der Dreiergruppe links, rechts, mitte die Reihenfolge beliebig sein kann.The features of claim 2 prevent that in the middle a ridge remains. Nevertheless, the saw teeth can remain very narrow. The accruing Chips stay very small. The drive power is minimized. Be on it pointed out that within the group of three left, right, middle the order can be anything.
Es wird nunmehr ein bevorzugtes Ausführungsbeispiel beschrieben. In der Zeichnung zeigen: Fig. 1 die Seitenansicht einer Zahnfolge, Fig. 2 die Ansicht gemaß dem Pfeil A in Fig. 1, Fig. 3 , 4 und 5 Schnitte längs der Linien 3-3 , 4-4 und 5-5 in Figur 1.A preferred embodiment will now be described. In The drawings show: FIG. 1 the side view of a sequence of teeth, FIG. 2 the view according to the arrow A in Fig. 1, Fig. 3, 4 and 5, sections along the lines 3-3, 4-4 and 5-5 in Figure 1.
Zwischen zwei Schneidenwanden 11, 12 ist eine Sügebandkette 13 geführt. Dabei befindet sich der Basisbereich 14, 15, 16 jedes Sägezahnes 18, 19, 21 zwischen den Schneidenwünden 11, 12 . Die Sagezahne 18, 19, 21 sind auf nichtdargestellte Weise miteinander verbunden.A chain conveyor 13 is guided between two cutting edge walls 11, 12. The base area 14, 15, 16 of each saw tooth 18, 19, 21 is located between the cutting edges 11, 12. The saw teeth 18, 19, 21 are not shown Way connected.
Der Sägezahn 18 hat oberhalb der Oberseite 22 , 23 der Schneidenwand 11, 12 einen Knick24 und ist von dort aus nach links mit einer Schwankung 26 abgebogen.The saw tooth 18 has above the top 22, 23 of the cutting edge wall 11, 12 a bend24 and from there it is turned to the left with a fluctuation 26.
Es folgt darauf der Sägezahn 21 , welcher mit einer Schrönkung 27 in gleicher Weise, jedoch nach rechts abgebogen ist. Schließlich folgt der Sägezahn 19, der überhaupt nicht beschränkt ist.This is followed by the saw tooth 21, which with a set 27 in the same way, but turned to the right. Finally, the sawtooth follows 19 that is not restricted at all.
Wie insbesondere aus Figur 2 ersichtlich ist, ist der Sägezahn 18 über die Breite der Schneidenwand 11 hinaus und der Sägezahn 21 über die Breite der Schneidenwand 12 mit seiner äußersten Kante hinaus geschränkt. Der Sägezahn 19 arbeitet dann den zwischen den beiden Sägezähnen 18, 21 stehenbleibenden Grat weg. Die Schnittbreite vergrößert sich also grob gesagt um das Zweifache, so daß Schnitte von etwa 0,5 - 1,5 mm Breite realisierbar bleiben.As can be seen in particular from FIG. 2, the saw tooth is 18 over the width of the cutting edge wall 11 and the saw tooth 21 over the width the cutting edge wall 12 with its outermost edge also set. The sawtooth 19 then works the burr that remains between the two saw teeth 18, 21 path. The cutting width increases roughly twice, so that Cuts with a width of around 0.5 - 1.5 mm can still be realized.
Die Sagezahnform von Figur 1 ist lediglich symbolisch. Die Form der Sagezahne kann auch eine andere sein.The sawtooth shape of Figure 1 is only symbolic. The shape of the Saw teeth can also be a different one.
Je nach Schnittproblem, je nach Drehmoment, je nach zur Verfugung stehender Antriebsleistung usw. kann man die Sägezähne auch in größerem Abstand anordnen und ggf.Depending on the cutting problem, depending on the torque, depending on the available standing drive power, etc. you can see the saw teeth at a greater distance arrange and if necessary
