Description

Gegenstand der Erfindung ist eine Segmentsäge, d. h. eine Kreissäge, bei der die Zähne an einzelnen Segmenten sitzen, die radial von außen in das Sägenblatt eingesetzt und fest mit ihm verbunden werden. An den radialen Stoßkanten solcher Segmente wurden bisher zur Verhinderung seitlichen Ausweichens Nieten parallel zur Sägenblattachse mit beiderseits versenkten flachen Köpfen eingezogen, deren Achsen in den Stoßkantenebenen liegen. Gemäß der Erfindung soll jedes Nieten an der zum Verhindern der Ausweichung dienenden Sicherung vermieden werden. Dies wird dadurch, erreicht, daß in die beiderseits zylindrisch erweiterten Löcher genau passende Stahlbolzen von entsprechendem H-förmigem Querschnitt eingelegt werden und der letzte Bolzen in der Weise eingebracht wird, daß mehrere der angrenzenden Segmente in den Stoßfugen dicht aneinanderliegend zu beiden Seiten des fraglichen Bolzens gegen diesel nach innen auf ihren Sitz eingeschwenkt werden, worauf erst diese Segmente mit dem Sägenblatt fest verbunden werden.The invention relates to a segment saw, i. H. a circular saw in which the Teeth sit on individual segments that are inserted radially from the outside into the saw blade and be firmly connected to him. At the radial abutting edges of such segments were previously to prevent lateral Dodge rivets parallel to the saw blade axis with flat heads recessed on both sides drawn in, the axes of which lie in the abutting edge planes. According to the invention, each rivet on the to prevent the Avoidance-serving backup. This is achieved in that in the holes on both sides cylindrically widened to match exactly matching steel bolts H-shaped cross-section are inserted and the last bolt is inserted in such a way that several of the adjacent Segments in the butt joints close together on either side of the one in question Bolt against diesel are swiveled inwards onto their seat, whereupon only these segments are firmly connected to the saw blade.

In der Zeichnung ist eine Ausführungsform der neuen Segmentbefestigung beispielsweise dargestellt.In the drawing, an embodiment of the new segment attachment is for example shown.

Fig. S zeigt die Stellung der letzten Zahnsegmente gegenüber dem Sägenblatt beim Einbringen des letzteren Stoßfugenbolzens.Fig. S shows the position of the last tooth segments in relation to the saw blade Insertion of the latter butt joint bolt.

In die Stoßfugen 2 der Zahnsegmente 1 sind, mit der Achse in der Stoßfugenebene liegend, zylindrische Ausfräsungen 3, 4 eingearbeitet, in welche die H-förmig profilierten Bolzen 5 genau hineinpassen. Beim Einsetzen der Segmente werden diese hintereinander angereiht, wobei immer ein Bolzen 5 eingelegt wird. Zum Einlegen des letzten Segments bzw. Bolzens 12 werden je zwei oder drei beiderseits' anstoßende Segmente 6, 7, 8 bzw. 9, 10, 11 um die Bolzen der Segmente 8 bzw. 11 so weit nach außen geschwenkt, daß- der Bolzen 12 eingelegt werden kann, worauf alle diese Segmente gemeinsam nach innen auf ihren Sitz zurückgeschwenkt werden und die Befestigung der Segmente zum Sägenblatt durch Vernieten u. dgl. bewirkt wird.In the butt joints 2 of the toothed segments 1 are, with the axis in the butt joint plane horizontal, cylindrical millings 3, 4 incorporated into which the H-shaped profiles Fit bolt 5 exactly. When inserting the segments, these are one behind the other lined up, always with a bolt 5 inserted. To insert the last one Segments or bolts 12 are each two or three on both sides' abutting segments 6, 7, 8 or 9, 10, 11 around the bolts of the segments 8 or 11 swiveled outwards so far that the bolts 12 are inserted can, whereupon all these segments are pivoted back together inwards onto their seat and the attachment of the segments to the saw blade by riveting and the like.
