Abstract

The saw blade (1) is provided with an inner pressure area (4) gradually decreasing towards the outer edge and transforming into a pulling area (3). The tension and the level of rigidity are evenly distributed, the thickness is not changed by deformation. In a second version the blade (1) is provided with a rolled trace close to the outer edge, an inner pressure area with the pressure created tension at the edge of the central bore, first decreasing towards the outer edge, then increasing with a maximum level at the rolled trace and abruptly changing into a pulling area beyond the boundary.

Kreissägeblatt mit Innendruck- und -zugspannungen dadurch gekennzeichnet, dass die innere Druckspannungszone (4) radial nach aussen abnimmt und fliessend in die äussere Zugspannungszone (3) übergeht und die Spannungen und Härten über die Sägendicken gleichbleibende Werte aufweisen und in in einer Sonderausführung die erfindungsgemässe Innenspannungsform mit der bekannten Spannungserzeugung mittels Walzen oder thermischem Spannen kombiniert ist.Circular saw blade with internal compressive and tensile stresses characterized in that the inner compressive stress zone ( 4 ) decreases radially outward and flows smoothly into the outer tensile stress zone ( 3 ) and the stresses and hardnesses have constant values across the saw thicknesses and, in a special version, the internal stress form according to the invention is combined with the known voltage generation by means of rolling or thermal clamping.
