Abstract

Ein Klemmriegel für die Wurfschaufeln (3) von Scheiben­ rotoren in Strahl- bzw. Zerkleinerungsvorrichtungen. Die Seitenkanten der Wurfschaufeln (3) sind in radiale Nuten der Scheiben des Rotors einschiebbar. Der Klemm­ riegel (1) ist gegen einen die beiden Scheiben verbinden­ den Zylinderbolzen (5) und gegen einen Ansatz (3a) an der Rückseite der Schaufel (3) abgestützt und weist Nuten mit einer in diese Nuten einsetzbaren Bügelfeder (6) auf. Ein Ende der Bügelfeder (6) ist gegen den Klemmriegel (1) zur Festlegung der Schaufel (3) im Scheibenrotor festgelegt. Der Klemmriegelkörper bildet dabei ein L-förmiges Winkel­ stück, das etwa rechtwinklig aufeinander zu verlaufende Auflageflächen (1a und 2a) aufweist, diese laufen in eine auf den Ansatz (3a) der Schaufel (3) auflegbare Schrägfläche (4) aus. A clamp bolt for the throwing blades (3) of discs rotors in blasting or shredding devices. The side edges of the throwing blades (3) are in radial Grooves of the rotor discs can be inserted. The clamp Bolt (1) is connected to one of the two panes the cylinder bolt (5) and against a shoulder (3a) on the Back of the blade (3) supported and has grooves a bow spring (6) which can be inserted into these grooves. A The end of the bow spring (6) is against the locking bolt (1) The blade (3) is fixed in the disc rotor. The clamp bolt body forms an L-shaped angle piece that is approximately perpendicular to each other Has contact surfaces (1a and 2a), these run into a on the shoulder (3a) of the blade (3) bevelled surface (4) off.
