Abstract

The blade has an auxiliary ring (2) concentrically connected with a saw blade body (1) in a connecting surface by welding, soldering and gluing. Screw holes (7) are formed in such a manner that compressive forces of retaining screws are transferred over an external area of heads of the retaining screws. The screw holes has an opening angle smaller than 90 degrees and are extended apart from a large head diameter area of the retaining screws in such a manner that a distance to a screw head is given without internal stress.

Description

Die bekannten Sägeblätter mit konischen angesenkten Befestigungslöchern haben in dem Lochbereich eine erhebliche ringförmige Verdickung, die eine erhebliche Verteuerung des Sägeblattes bewirkt.The known saw blades with conical countersunk mounting holes have in the hole area a considerable annular Thickening, which is a considerable increase in the price of the saw blade causes.

Der Erfindung liegt die Aufgabe zugrunde eine Säge zu schaffen, deren Herstellkosten geringer sind und die Verbindungssteifheit mit dem Maschinenflansch mindestens gleich groß ist.Of the Invention has for its object to provide a saw whose production costs are lower and the connection stiffness with the machine flange at least the same size.

Das erfindungsgemäße Sägeblatt besteht aus einem Sägeblattkörper ohne Verdickung im Befestigungsbereich und einem Zusatzring, der mittels Schweißen oder Löten oder Kleben mit dem Sägeblattkörper verbunden ist und einen Außendurchmesser aufweist der etwas größer ist als der Außendurchmesser des Maschinenflansches und die konischen Befestigungslöcher so gestaltet sind, daß die Befestigungsschraubenköpfe nur direkten Druck ausüben gegen den Teil der Säge, der nicht am Maschinenflansch anliegt und dieser Druck vorzugsweise nur vom äußeren Schraubenkopfbereich erzeugt wird.The Saw blade according to the invention consists of a saw blade body without Thickening in the attachment area and an additional ring, by means of welding or Soldering or Gluing connected to the saw blade body is and an outside diameter which is slightly larger as the outer diameter of the machine flange and the conical mounting holes so are designed that the mounting screw heads only apply direct pressure against the part of the saw, which is not applied to the machine flange and this pressure preferably only from the outer screw head area is produced.

1 zeigt das erfindungsgemäße Sägeblatt mit dem Sägeblattkörper (1), den Zusatzring (2), die Seitenschneiden (3) und die Schraubenlöcher (7). 1 shows the saw blade according to the invention with the saw blade body ( 1 ), the additional ring ( 2 ), the side cutting edges ( 3 ) and the screw holes ( 7 ).

2 zeigt einen radialen schnitt durch einen mittenbohrungsnahen Bereich des Sägeblattes mit dem Sägeblattkörper (1), dem Zusatzring (2) der Verbindungsfläche (6), dem Schraubenloch (7), der Befestigungsschraube (4) und dem Maschinenflansch (5) an der Seite des Zusatzrings (2). 2 shows a radial section through a central bore near area of the saw blade with the saw blade body ( 1 ), the additional ring ( 2 ) of the interface ( 6 ), the screw hole ( 7 ), the fixing screw ( 4 ) and the machine flange ( 5 ) on the side of the additional ring ( 2 ).

3 zeigt einen ähnlichen radialen Schnitt wie 2 mit dem Sägeblattkörper (1), dem Zusatzring (2), der Verbindungsfläche (6), dem Schraubenloch (7), der Befestigungsschraube (4) und dem Maschinenflansch (5) an der Seite des Sägeblattkörpers (1). 3 shows a similar radial cut as 2 with the saw blade body ( 1 ), the additional ring ( 2 ), the interface ( 6 ), the screw hole ( 7 ), the fixing screw ( 4 ) and the machine flange ( 5 ) on the side of the saw blade body ( 1 ).
