Quick clamping arrangement for circular saw blades

摘要

The saw clamping arrangement has a fixing flange (10) which fastens onto the saw drive shaft. The flange has at least three clamp bolts (14) arranged in a circle. The bolts are parallel to a central axis (11) of the flange and project over its forward connection side (12). Each bolt has a radially projecting clamp head (13) at its free end and are put under tension by a spring (15). The blade itself has a blade mounting plate with at least three keyhole slots in it which correspond to the clamp bolts. When the drive shaft turns, the blade fixing flange acts on centrifugal force elements (18) which are balls and is held under centrifugal force in position.
