Sägeblatt bzw. Distanzring für Kreissägemaschine und deren Anordnung auf der MaschinenwelleSaw blade or spacer ring for circular saw machine and their arrangement on the machine shaft
Die bekannten Kreissägeblätter bzw. Distanzringe zwischen den Sägeblättern haben den Nachteil, daß immer zwischen deren Mittenbohrung und Maschinenwelle eine fertigungsbedingte Toleranz gegeben ist, die dazu führt, daß die Sägeblätter bzw. Distanzringe immer außermittig gedreht werden und somit durch die Zentrifugalkräfte Schwingungen der Sägeblätter und der Maschinenwelle entstehen.The known circular saw blades or spacer rings between the saw blades have the disadvantage that there is always a manufacturing-related tolerance between their center hole and the machine shaft, which means that the saw blades or spacer rings are always turned off-center and thus vibrations of the saw blades and the machine shaft occur due to the centrifugal forces.
Der Erfindung liegt die Aufgabe zugrunde, diese Schwingungen zu reduzieren und somit einen ruhigeren und besseren Lauf der Sägeblätter zu ermöglichen.The invention is based on the task of reducing these vibrations and thus enabling a smoother and better running of the saw blades.
Das erfindungsgemäße Sägeblatt bzw. der Distanzring weisen in der Bohrung mindestens eine Anpressvorrichtung auf, die durch ihre formschlüssige radiale Verschiebbarkeit das Sägeblatt spielfrei auf der Maschinenwelle positionieren. Zum Ausgleich der verbleibenden Restunwucht kann bei Maschinen mit mehreren Sägeblättern die Anordnung der Sägeblätter bzw. Distanzringe so vorgenommen werden, daß sich die Anpressvorrichtungen bei benachbarten Sägeblättern bzw. Distanzringen immer um 180° versetzt gegenüber liegen, so daß immer die Hälfte um 180° gedreht gegenüber der anderen Hälfte angeordnet ist.The saw blade or spacer ring according to the invention has at least one pressing device in the bore, which positions the saw blade on the machine shaft without play due to its positive radial displacement. To compensate for the remaining residual imbalance, the saw blades or spacer rings can be arranged in such a way that the pressing devices on adjacent saw blades or spacer rings are always offset by 180°, so that half is always arranged rotated by 180° relative to the other half.
Figur 1 zeigt zwei erfindungsgemäße Sägeblätter (1.1 und 1.2), die die spiralförmigen Keilnuten (1.1.2 und 1.2.2) jeweils aufweisen, wobei letztere um 180° gegenüberliegend angeordnet sind. In den spiralförmigen Keilnuten (1.1.2 und 1.2.2) sind die entsprechend gewölbt geformten Anpresskeile (6) angeordnet, die durch Verschieben in Umfangsrichtung eine radiale Kraft auf die Sägeblätter (1.1 bzw. 1.2) dergestalt ausüben, daß diese gegen die Welle (2) gedrückt werden und somit ein radiales Spiel verhindern.Figure 1 shows two saw blades according to the invention (1.1 and 1.2), each of which has the spiral-shaped keyways (1.1.2 and 1.2.2), the latter being arranged 180° opposite one another. The correspondingly curved pressure wedges (6) are arranged in the spiral-shaped keyways (1.1.2 and 1.2.2), which exert a radial force on the saw blades (1.1 and 1.2) by moving in the circumferential direction in such a way that they are pressed against the shaft (2) and therefore prevent radial play.
Figur 2 zeigt zwei weitere Ausführungsformen, bei denen einmal das Anpressplattchen (3) durch eine ovale Excenterscheibe (4) mittels Drehung dieser Scheibe in einem ovalen Loch gegen die Welle gedrückt ist, und eine weitere Ausführungsform zeigt den Anpressfinger (5), der über einen gleichen ovalen Excenter radial verbiegbar ist. Die ovale Excenterscheibe (4) weist einen Innensechskant auf, um dieselbe mit einfachen Mitteln drehen zu können.Figure 2 shows two further embodiments, in which the pressure plate (3) is pressed against the shaft by an oval eccentric disk (4) by rotating this disk in an oval hole, and a further embodiment shows the pressure finger (5) which can be bent radially via the same oval eccentric. The oval eccentric disk (4) has a hexagon socket so that it can be rotated using simple means.
Figur 3 zeigt eine Ausführungsform, bei der die radiale Anpressung mittels eines Anpreßstegs (7) erfolgt, der in einem geringen Abstand zum Bohrungsrand angeordnet ist und ebenfalls durch eine ovale Excenterscheibe, die sich in einem ovalen Loch befindet, radial verbiegbar ist.Figure 3 shows an embodiment in which the radial pressure is achieved by means of a pressure web (7) which is arranged at a small distance from the edge of the bore and can also be bent radially by an oval eccentric disk which is located in an oval hole.
Figur 4 zeigt eine Ausführungsform, bei der die radiale Anpressung des Distanzrings (8) bzw. eines sehr dicken Sägeblattes durch eine Schraube (9) erfolgt, die schräg zur Drehachse dergestalt angeordnet ist, daß ihre Spitze gegen die Welle (2) zur Druckwirkung drehbar ist.Figure 4 shows an embodiment in which the radial pressing of the spacer ring (8) or of a very thick saw blade is carried out by a screw (9) which is arranged obliquely to the axis of rotation in such a way that its tip can be rotated against the shaft (2) to exert pressure.
Es sind noch weitere Ausführungsformen möglich, insbesondere Formen, bei denen der Excenter über einen dünnen Steg mit dem Sägeblatt (1) verbunden ist und somit mittels elastischer Verformung dieses Steges eine Einheit mit dem Sägeblatt bildet.Other embodiments are also possible, in particular forms in which the eccentric is connected to the saw blade (1) via a thin web and thus forms a unit with the saw blade by means of elastic deformation of this web.
