Abstract

Eine Einrichtung zur lösbaren Befestigung eines Schneidzahnes (10) auf einer mit einer Mehrzahl von Schneidzähnen (10) versehenen Schneidwelle (100) für eine Zerkleinerungsvorrichtung, mit einem auf der Schneidwelle (100) angeordneten Zahnträger (20), der einen mit einer Aufnahmebohrung (22) versehenen Anschlag (23) aufweist und zur Aufnahme des Schneidzahnes (10) vorgesehen ist, und mit einer durch die Aufnahmebohrung (22) hindurchragenden Schraube (50) zur klemmenden Befestigung des Schneidzahnes (10) im Zahnträger (20), zeichnet sich aus durch folgende Merkmale:
a) in dem Zahnträger (20) ist mindestens ein erster prismatisch ausgestalteter Sitz (21) vorgesehen,
b) am Schneidzahn (10) ist ein mit dem Sitz (21) zusammenwirkender Fuß (12) ausgebildet,
c) eine Durchgangsbohrung (11) im Schneidzahn (10) ist konisch ausgebildet,
d) ein mit einer zentralen Bohrung (32) versehener Spannbolzen (30) weist einen mit dem Konus der Durchgangsbohrung (11) zusammenwirkenden Gegenkonus (31) auf,
e) über die durch die zentrale Bohrung (32) hindurchgeführte Schraube (50) ist der Spannbolzen (30) in die Durchgangsbohrung (11) des Schneidzahnes (10) spannbar, wodurch der Fuß (12) des Schneidzahnes (10) in den prismatischen Sitz (21) des Zahnträgers (20) und gegen den Anschlag (23) verspannt wird.

A device for detachably fastening a cutting tooth (10) on a cutting shaft (100) for a comminuting device provided with a plurality of cutting teeth (10), comprising a tooth carrier (20) arranged on the cutting shaft (100) and having a receiving bore (22 ) provided stop (23) and for receiving the cutting tooth (10) is provided, and with a through the receiving bore (22) projecting screw (50) for clamping attachment of the cutting tooth (10) in the tooth carrier (20), characterized by following features:
a) in the tooth carrier (20) at least a first prismatic ausgestalteter seat (21) is provided,
b) a tooth (12) cooperating with the seat (21) is formed on the cutting tooth (10),
c) a through hole (11) in the cutting tooth (10) is conical,
d) a clamping bolt (30) provided with a central bore (32) has a counter-cone (31) cooperating with the cone of the through-bore (11),
e) via the through the central bore (32) guided by screw (50) of the clamping bolt (30) in the through hole (11) of the cutting tooth (10) can be tensioned, whereby the foot (12) of the cutting tooth (10) in the prismatic seat (21) of the tooth carrier (20) and against the stop (23) is clamped.
