Description

Das Hauptpatent 914 549 bezieht sich auf Bandsägeblattführungen an Bandsägemaschinen, bei welchen die Bandsägeblätter oder Bandmesser zwischen zwei gegeneinander verschiebbaren Seitenrollen sowie einer verstellbaren Rückenrolle geführt werden und bei denen die Laufwellen dieser Rollen so ausgebildet sind, daß ihre Enden einen Konus aufweisen, der sich mit einer tragenden Fläche in einem verstellbaren Spurlager bei den Seitenrollen und in einem feststehenden Spurlager bei der Rückenrolle abstützt, wobei Lagerbuchsen und Spurlager aus Sintermetall hergestellt sind.The main patent 914 549 relates to band saw blade guides Band saw machines, in which the band saw blades or band knives between two side rollers that can be slid against each other and an adjustable back roller are performed and in which the shafts of these rollers are designed so that their ends have a cone that is adjustable with a supporting surface Thrust bearing for the side rollers and in a fixed thrust bearing for the back roller supported, bearing bushings and thrust bearings are made of sintered metal.

Es hat sich gezeigt, daß die Verstellung der seitlichen Laufrollen 8 durch die Spurlager 2 bei zunehmender Abnutzung des Laufkranzes eine Vergrößerung des Abstandes zwischen Lagerbuchse 6 und Laufrolle verursacht. Dadurch werden die Lager 6 stärker belastet. Um das zu vermeiden und den Abstand zwischen Lagerbuchse 6 und Seitenrolle 8 auch bis zum vollen Verschleiß des Laufkranzes gleichbleibend zu halten, wird gemäß der Erfindung, wie dies in der Zeichnung beispielsweise dargestellt ist, die gesamte Lagerung, bestehend aus der Lagerbuchse 6, dem Spurlager 2 und der Abdichtung 7, in eine Gewindebüchse 29 eingebaut, die ihrerseits im Lagergehäuse 12 durch Drehen in axialer Richtung verschiebbar ist und die in jeder gewünschten Lage dadurch festgehalten wird, daß ein unter Federdruck I9 stehender Bolzen 2o in der Innenseite des Spurlagerkopfes einrastet. Die Schmierkammer I0 des. Spurlagers 2 erhält durch den Rändelkopf hindurch eine Füllöffnung, die mit einer Schraube 32 und einer Dichtung 31 verschlossen ist.It has been shown that the adjustment of the lateral rollers 8 due to the thrust bearing 2 with increasing wear of the tread an enlargement caused by the distance between the bearing bush 6 and the roller. This will make the Camp 6 heavily loaded. To avoid that and the distance between the bearing bush 6 and side roller 8 also remain the same until the tread is fully worn to keep is according to the invention, as shown in the drawing, for example is, the entire storage, consisting of the bearing bush 6, the thrust bearing 2 and the seal 7, built into a threaded bushing 29, which in turn is in the bearing housing 12 is displaceable by rotating in the axial direction and in any desired Position is held in that a standing under spring pressure I9 bolt 2o engages in the inside of the thrust bearing head. The lubrication chamber I0 of the thrust bearing 2 receives a filling opening through the knurled head, which is connected to a screw 32 and a seal 31 is closed.
