Abstract

The saw blade has concentric rings on one side and the toothed rings (2) have teeth on their outer circumference. The rings are connected concentric to the saw blade (1) and have on their outer faces a radial free angle and /or on a radial length level with the teeth an axial projection (5). They adjoin flush with the saw blade on one side over their entire surface. The toothed rings can be connected to the blade by screws (3) or rivets.

Description

Es sind Kreissägeblätter bekannt mit beidseitig aufgeschraubten Ringen zur Versteifung des Säge­ blattes, die jedoch den Nachteil aufweisen, daß diese bei krummen Hölzern zu Verbrennungen neigen und damit das Blatt deformieren.Circular saw blades are known with both sides screwed rings to stiffen the saw sheet, but which have the disadvantage that these tend to burn when wood is crooked and deform the sheet.

Desweiteren sind Sägeblätter mit verdicktem Bund bekannt zur Versteifung des Sägeblattes und seitlichen Ringen mit Zähnen, die jedoch den Nachteil aufweisen, daß die Zähne 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.There are also saw blades with a thickened collar known for stiffening the saw blade and side rings with teeth, however, the Disadvantage that the teeth due to Manufacturing tolerances not exactly on the saw blade and press sawdust into this gap and these saw blades in the Manufacturing are very expensive.

Außerdem weisen diese Sägeblätter mit verdicktem Bund und seitlich aufgeschraubten Zahnringen den Nachteil auf, daß die axiale Führung des Säge­ blattes aufgrund der Fertigungstoleranzen nur im Bereich des verdickten Bundes möglich ist, und die Zahnhöhe bei dieser Ausführungsform nicht zur Ver­ steifung 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 Deformations­ gefahr durch die Ringverzahnung minimiert ist. In addition, these saw blades with thickened Collar and laterally screwed on toothed rings Disadvantage that the axial guidance of the saw due to the manufacturing tolerances only in Area of the thickened covenant is possible, and the Tooth height in this embodiment not for ver stiffness of the saw blade is used and thus the Stabilization diameter is smaller than that Outside diameter of the toothed rings. This can be larger than the outside diameter of the Stabilization rings without teeth, because at curved wood the heating and deformation danger is minimized by the ring toothing.  

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 To create a saw blade that is not in production is very complex and with too high cutting heights has no burns and increased Lateral stability through the lateral toothed rings Has.

Das erfindungsgemäße Sägeblatt weist coaxiale Zahnringe auf, die an ihrem Aussenumfang Zähne aufweisen, die auf den Aussenflächen 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 is coaxial Toothed rings that have teeth on their outer circumference have clearance angles on the outer surfaces or have protrusions, and with screws with the saw blade are axially connected and radially through Dowel pins are precisely positioned, with the gear rings on one side with its entire surface flush on Fit the saw blade.

Fig. 1 zeigt das Sägeblatt (1) in Seitenansicht mit dem Zahnring (2), den Schrauben (3), den Paßstiften (4) und den axialen Vorsprüngen (5). Fig. 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 ).

Fig. 2 zeigt Fig. 1 nach dem Schnitt A-A mit den Zahnringen (2.1 und 2.2), den Schrauben (3), den Paßstiften (4) und dem radialen Freiwinkel (α) und den axialen Vorsprüngen (5). Fig. 2 shows Fig. 1 after section AA with the toothed rings ( 2.1 and 2.2 ), the screws ( 3 ), the dowel pins ( 4 ) and the radial clearance angle (α) and the axial projections ( 5 ).
