Kreissägeblatt mit beidseitigen Zahnringen und gleicher Sägendicke innerhalb der Zahnringflächen Circular saw blade with toothed rings on both sides and equal saw thickness within the toothed ring surfaces
Es sind Kreissägeblätter bekannt mit beidseitig - aufgeschraubten Ringen zur Versteifung des Sägeblattes, die jedoch den Nachteil aufweisen, daß diese bei krummen Hölzern zu Verbrennungen neigen und damit das Blatt deformieren.Circular saw blades are known with rings screwed on both sides to stiffen the saw blade, but these have the disadvantage that they tend to burn when cutting crooked wood and thus deform the blade.
Desweiteren sind Sägeblätter mit verdicktem Bund bekannt zur Versteifung des Sägeblattes und seitlichen Ringen mit Zähnen, die jedoch den Nachteil aufweisen, daß die Zahne aufgrund der Fertigungstoleranzen nicht genau am Sägeblatt anliegen und in diesen Spalt Sägemehl gepresst wird und außerdem diese Sägeblätter in der Herstellung sehr teuer sind.Furthermore, saw blades with a thickened collar to stiffen the saw blade and side rings with teeth are known, but these have the disadvantage that the teeth do not fit exactly on the saw blade due to the manufacturing tolerances and sawdust is pressed into this gap. In addition, these saw blades are very expensive to manufacture.
Außerdem weisen diese Sägeblätter mit verdicktem Bund und seitlich aufgeschraubten Zahnringen den Nachteil auf, daß die axiale Führung des Sägeblattes aufgrund der Fertigungstoleranzen nur imIn addition, these saw blades with a thickened collar and laterally screwed tooth rings have the disadvantage that the axial guidance of the saw blade can only be achieved in the

Zahnhöhe bei dieser Ausführungsform nicht zur Versteifung des Sägeblattes genutzt ist und somit der Stabilisierungsdurchmesser kleiner ist als der Aussendurchmesser der Zahnringe. Dieser kann größer sein als der Aussendurchmesser der Stabilisierungsringe ohne Zähne, weil bei gekrümmten Hölzern die Erhitzungs- und Deformationsgefahr durch die Ringverzahnung minimiert ist.In this design, the tooth height is not used to stiffen the saw blade and thus the stabilization diameter is smaller than the outer diameter of the toothed rings. This can be larger than the outer diameter of the stabilization rings without teeth because the risk of heating and deformation is minimized by the ring teeth when working with curved wood.

Der Erfindung liegt die Aufgabe zugrunde, ein Sägeblatt zu schaffen, das in der Fertigung nicht sehr aufwendig ist und bei zu hohen Schnitthöhen keine Verbrennungen aufweist und eine erhöhte Seitenstabilität durch die seitlichen Zahnringe hat.The invention is based on the object of creating a saw blade which is not very complex to manufacture and which does not burn at too high cutting heights and which has increased lateral stability due to the lateral tooth rings.
Das erfindungsgemäße Sägeblatt weist coaxiale Zahnringe auf, die an ihrem Aussenumfang Zähne aufweisen, die auf den Aussenflachen Freiwinkel bzw. Überstände aufweisen, und mit Schrauben mit dem Sägeblatt axial verbunden sind und radial durch Paßstifte genau positioniert sind, wobei die Zahnringe auf einer Seite mit ihrer gesamten Fläche bündig am Sägeblatt anliegen.The saw blade according to the invention has coaxial toothed rings which have teeth on their outer circumference, which have clearance angles or projections on the outer surfaces, and are axially connected to the saw blade by screws and are precisely positioned radially by dowel pins, the toothed rings lying flush with the saw blade with their entire surface on one side.
Figur 1 zeigt das Sägeblatt (1) in Seitenansicht mit dem Zahnring (2), den Schrauben (3), den Paßstiften (4) und den axialen Vorsprüngen (5).Figure 1 shows the saw blade (1) in side view with the toothed ring (2), the screws (3), the dowel pins (4) and the axial projections (5).
Figur 2 zeigt Figur 1 nach dem Schnitt A-A mit den Zahnringen (2.1 und 2.2), den Schrauben (3), den Paßstiften (4) und dem radialen Freiwinkel und den axialen Vorsprüngen (5).Figure 2 shows Figure 1 according to section A-A with the toothed rings (2.1 and 2.2), the screws (3), the dowel pins (4) and the radial clearance angle and the axial projections (5).
