Abstract

The chain saw sharpened consists of two grinding spirals rotating in a casing about an axis parallel to the chain bar, of an appropriate size and shape for the saw chain. The spirals are fitted to the chain bar in such a manner that the saw chain teeth, when the saw is running, are ground by them and the grinding spirals are rotated.

Description

Jetziger Stand mit ZielsetzungCurrent status with objective

Wenn nach längerem Arbeiten mit einer Motorkettensäge die Sägekette stumpf wird, muß man sie entweder ausbauen und zum Schärfen bringen oder kann es mit einer kleinen Feile selbst versuchen. Wobei es in diesem Falle viel Übung erfordert, ein gleichmäßiges Ergebnis zu erreichen. If after a long period of work with a motor chain saw the saw chain becomes dull, you have to you can either remove and sharpen them or use a small file try yourself. In this case, it takes a lot of practice, an even result to reach.

Auch gibt es für den Heimwerker diverse Lösungen mit dem Akku-Schrauber mit Schleifaufsatz. In jedem Falle aber verstreicht zuviel Zeit. There are also various solutions for DIY enthusiasts with the cordless screwdriver Sanding attachment. In any case, too much time passes.

Der neue Kettenschärfer soll selbst für einen Waldarbeiter ohne elek. Strom, Werkbank und Zeit, schnell und einfach zu nutzen sein. The new chain sharpener should even for a forest worker without elec. Electricity, workbench and Time to be quick and easy to use.

Ein handliches Gerät, welches von unten an das Sägeschwert einrastet und von der Säge selbst angetrieben wird, wäre die Lösung. A handy device that snaps into place on the saw bar and from the saw self-propelled would be the solution.

Aufbau und FunktionsweiseStructure and functionality

Der Kettenschärfer besteht aus einem passendem Gehäuse mit Befestigungsmöglichkeit und aus zwei gleich großen Walzen, die sich der Form des Sägeschwertes, welches meist eliptisch ist, anpassen, also sich in der Mitte verjüngen. The chain sharpener consists of a suitable housing with mounting option and from two equal-sized rollers, which shape the saw blade, which is usually is elliptical, adapt, i.e. taper in the middle.

Jede Walze ist etwas länger wie der Abstand von zwei linken oder rechten Sägezähnen und ausreichend dick. Each roller is slightly longer than the distance from two left and right saw teeth and sufficiently thick.

Schauen wir uns die Kettenglieder einer Sägekette einmal genauer an. Auf einem Kettenglied mit linkem Sägezahn folgt ein Zwischenglied, darauf folgt ein Kettenglied mit rechtem Sägezahn, darauf folgt wieder ein Zwischenglied und mit dem darauf folgendem Kettenglied mit linkem Sägezahn geht es von vorn los. Let's take a closer look at the chain links of a saw chain. On one Chain link with left saw tooth is followed by an intermediate link, followed by a chain link with right sawtooth, followed by another pontic and with it The following chain link with the left saw tooth starts again.

Auf der Mantelfäche jeder Walze ist ein im Querschnitt ausreichend großer runder Sehleifkörper so angebracht, daß er von der Kante zur Bodenfläche der Walze bis zur Kante der Deckfläche der Walze führt und dabei einmal die Walze umrundet. (Vergleichbar mit einer Drahtspirale die einmal um die Walze gewickelt ist.) There is a sufficiently large round cross section on the surface of each roller Solleifkörper attached so that it from the edge to the bottom surface of the roller to the edge the top surface of the roller leads and once around the roller. (Comparable to a wire spiral that is once wrapped around the roller.)

Da eine Walze für die linken und eine für die rechten Sägezähne zuständig sein soll, hat eine Walze die Schleifspirale links herum und die andere rechts herum. Since one roller is supposed to be responsible for the left and one for the right saw teeth, one has Roll the grinding spiral to the left and the other to the right.

Der Durchmesser der Walze entscheidet, in welchem Winkel die Schleifspirale die Sägezähne schleift und mit welchem Drehwiderstand das geschieht. The diameter of the roller determines the angle at which the grinding spiral Saw teeth grinds and with what rotational resistance that happens.

Der Drehwiderstand kann noch zusätzlich mit einer Bremsvorrichtung erhöht werden. The rotational resistance can also be increased with a braking device.

Soll nun der Kettenschärfer an das Sägeschwert angebracht werden, muß die Schleifspirale durch Drehen der Walze vor den passenden Sägezahn plaziert werden. If the chain sharpener is to be attached to the saw blade, the grinding spiral must be used be placed in front of the matching saw tooth by turning the roller.

Wird jetzt die Kette vom Motor der Säge angetrieben, so schleift der Sägezahn an der Schleifspirale entlang und bringt so die Walze in eine Drehbewegung. If the chain is now driven by the saw motor, the saw tooth grinds against the Along the grinding spiral, thus causing the roller to rotate.

Die Schleifspirale ist lang genug und passend gedreht, um den nächsten Sägezahn zu fassen. Soll nun die Kette geschärft werden, wird je eine Seite der Zähne durch Ansetzen der passenden Schleifspirale und kurzes Betreiben der Säge geschliffen. The grinding spiral is long enough and rotated to fit the next saw tooth. If the chain is to be sharpened, one side of the teeth is attached by attaching the suitable grinding spiral and brief operation of the saw.
