Description

KAISERLICHESIMPERIAL

Der vorliegende Staubring bleibt trotz der Abnutzung, welcher er naturgemäfs unterliegt, durch die ihn concentrisch umgebende Stahlfeder α in ununterbrochener Wirksamkeit. Derselbe besteht aus einem (15 mm) starken Filzring b, welcher unten einen radialen Ausschnitt (von im Mittel 30 mm) hat; derselbe ist auf beiden Seiten eingefafst durch die Lederplättchen d, welche eine Stärke von etwa 3 mm haben.The present dust ring remains in uninterrupted effectiveness despite the wear and tear to which it is naturally subject, due to the steel spring α surrounding it concentrically. It consists of a (15 mm) thick felt ring b, which has a radial cutout at the bottom (with an average of 30 mm); it is enclosed on both sides by the leather platelets d, which are about 3 mm thick.

Die äufserlich von der Kreislinie abweichende Form, welche dem Staubringe durch die vier in der vorderen Ansicht mit dl bezeichneten Lederplättchen gegeben wird, wurde gewählt, um es zu vermeiden, dafs der Staubring, welcher durch die 1,30 mm starke Feder α ziemlich fest gegen die Achse angeprefst wird, sich mit demselben drehen kann, sondern in der Hülse der Achsbüchse festliegt.The shape deviating from the circular line, which is given to the dust ring by the four leather platelets marked d 1 in the front view, was chosen to avoid that the dust ring, which is formed by the 1.30 mm thick spring α , becomes quite firm is pressed against the axle, can rotate with the same, but is fixed in the sleeve of the axle bushing.

Die dadurch aufserhalb der Federn entstehenden Zwischenräume zwischen diesen einander gegenüberliegenden Lederplättchen sind durch die aus Filz hergestellten Eckstücke c ausgefüllt.The resulting spaces outside the springs between these opposing leather platelets are filled by the corner pieces c made of felt.

Die beiden unteren gleich grofsen, einen Kreisabschnitt bildenden Lederplättchen d greifen auf jeder Seite des Filzringes über einander, damit die beim Beginn des Gebrauches noch rund 30 mm weite Oeffnung im Filzring durch diese gehörig gedeckt wird. The two lower leather platelets d of the same size, forming a circular segment, overlap each other on each side of the felt ring so that the opening in the felt ring, which is still around 30 mm wide at the beginning of use, is properly covered by it.

Je mehr sich der Ausschnitt im Filzring infolge der Abnutzung des. letzteren auf seiner Lauffläche schliefst, desto weiter schieben sich diese beiden Lederplättchen über einander.The more the cutout in the felt ring is due to the wear and tear of the latter on its The tread is asleep, the further these two leather plates slide over each other.

Der Filzring und die beiderseitigen Lederplättchen werden durch eine von der inneren Seite des Ringes, mit welcher er sich an den Bund der Achse anschliefst, 1 5 mm abstehende, aus Kupferdraht hergestellte Naht fest mit einander verbunden.The felt ring and the leather discs on both sides are replaced by one of the inner Side of the ring with which it connects to the collar of the axle, 1 5 mm protruding, Seam made of copper wire firmly connected to each other.

Damit sich der Staubring gleich von vornherein recht dicht an den Bund der Achse anschliefst, stehen die Lederplättchen gegen den Filzring in noch ungebrauchtem Zustande desselben um 2 mm zurück.So that the dust ring is right from the start quite close to the collar of the axle then, the leather platelets stand against the felt ring in a still unused condition the same back by 2 mm.

Nur die beiden unteren über einander greifenden Lederplättchen fügen sich unten in der Breite der Oeffnung im Filzring, und zwar, um diese vollständig zu decken, dicht an die Achse an.Only the two lower, overlapping leather plates fit into the bottom the width of the opening in the felt ring, in order to cover it completely, tightly to the axis.

Die Lederplättchen, mit welchen der Filzring zu beiden Seiten eingefafst ist, dienen auch zu einer sicheren Führung der zwischen ihnen liegenden, den Filzring concentrisch umgebenden Feder a. The leather platelets with which the felt ring is framed on both sides also serve to reliably guide the spring a lying between them and concentrically surrounding the felt ring.

Die in neuem Zustande des Staubringes im Mittel 30 mm betragende Oeffnung des Filzringes wird mit dem Verschleifs desselben successive auf Null reducirt. Er ist dann bis in die Nähe der centralen Naht abgeschlissen und dann auch verbraucht, was aber erst nach jahrelangem Gebrauch desselben erfolgt.In the new condition of the dust ring, the opening of the felt ring was on average 30 mm is successively reduced to zero as it wears away. He's up then in the vicinity of the central seam torn off and then also used up, which, however, only after years of use of the same.
