KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Vorliegende Erfindung hat zum Gegenstande die Wieder befestigung eines Sägegatterzapfens, welcher in seinem Sitze locker geworden ist; es werden dadurch der Bruch des Zapfens und die damit auftretenden, oft verderblichen Begleiterscheinungen verhütet.The present invention has as its object the reattachment of a saw gate pin, who has become loose in his seat; it will break the pin and prevents the often perishable side effects that occur with it.
Die bisher im Gebrauch befindlichen derartigen Zapfen sitzen meist nur in einer einfachen kegeligen Bohrung. Durch die vielfachThe pins of this type that have been in use up to now usually only sit in a simple one tapered bore. Through the multiple
ίο wiederholten harten Stöße und durch das Warmlaufen der Zapfen in ihren Lagern lockern sich ihre Schäfte in deren Bohrungen, und zwar an den der Lagerschale zunächst liegenden Schaftenden immer mehr und mehr, während die anderen Enden der Zapfenschäfte noch vollständig festsitzen. Im Betriebe wird nun das locker gewordene Stück des Zapfenschaftes bei jeder Umdrehung ein wenig hin und her gebogen. Dies genügt aber, um schließlich einen Zapfenbruch herbeizuführen. Hierbei kommen dann wiederum in sehr vielen Fällen viele andere Brüche vor, und die zertrümmerten und herumfliegenden Stücke gefährden die in der Nähe befindlichen Personen.ίο repeated hard knocks and through that If the pins in their bearings warm up, their shafts loosen in their bores, and more and more at the shaft ends that are closest to the bearing shell, while the other ends of the tenon shafts are still fully seated. In the company will now the loosened piece of the peg shaft a little with each turn and bent forward. However, this is sufficient to ultimately cause a tangential break. In many cases, many other fractures occur, and the ones that are shattered and flying pieces endanger the people in the vicinity.
Diese Nachteile werden durch die neue nachstellbare Zapfenbefestigung leicht vermieden. Bei derselben wird, sobald der kegelige Zapfenschaft in seine kegelige Bohrung in der üblichen Weise eingesetzt ist, eine kegelige und aufgeschlitzte Hülse über das Lagerstellenende des Zapfens geschoben, welche außen in eine zum kegeligen Zapfenschaft entgegengesetzt kegelige Bohrung und innen auf den kegeligen Zapfenschaft genau paßt.These disadvantages are easily avoided by the new adjustable pin fastening. In the same, as soon as the tapered pin shank in its tapered bore in the is used in the usual way, a tapered and slit sleeve over the bearing point end of the pin pushed, which on the outside in a tapered bore opposite to the conical pin shaft and inside fits exactly on the tapered journal shaft.
Die Hülse wird mittels einer runden Mutter in ihre Bohrung und auf den Zapfenschaft fest aufgedrückt. Dabei wird zugleich die Mutter gegen Losdrehung gut gesichert. Es ist besonders darauf zu achten, daß die Hülse und Mutter sich nachstellen lassen, wozu etwa 4 mm Spielraum genügen. Hat der Zapfen nun eine Zeitlang gearbeitet, dann löst man die Sicherung und zieht mittels der Mutter die Hülse in ihrer Bohrung und auf dem Zapfen nach. Der Zapfen sitzt dann wieder vollständig fest und kann eine Zeitlang laufen, bis ein abermaliges Nachstellen erforderlich wird. Die Zeichnung stellt ein Ausführungsbeispiel der Erfindung dar. Über den eigentlichen Zapfen 1 wird eine aufgeschlitzte hohlkegelige Hülse 8 geschoben, welche innen auf den kegeligen Zapfenschaft 3 und außen in die kegelige Erweiterung 9 genau hineinpaßt, welche der kegeligen Bohrung 4 für den Zapfenschaft 3 entgegengesetzt gerichtet ist. Die Hülse 8 wird mittels einer auf den Zapfenschaft 3 aufschraubbaren Mutter 7 fest in ihre Bohrung hineingedrückt.The sleeve is inserted into its bore and onto the journal shaft by means of a round nut firmly pressed. At the same time, the nut is well secured against loosening. It it is particularly important to ensure that the sleeve and nut can be readjusted, for example 4 mm clearance is sufficient. If the tenon has worked for a while, then you loosen it the fuse and pulls the sleeve in its bore and on the by means of the nut Cones after. The pin is then completely tight again and can run for a while, until it is necessary to readjust again. The drawing represents an embodiment of the invention. Over the actual pin 1 is a slit hollow conical Sleeve 8 pushed, which inside on the tapered pin shaft 3 and outside in the conical extension 9 fits exactly which of the conical bore 4 for the pin shank 3 is directed in the opposite direction. The sleeve 8 is by means of a on the pin shaft 3 screw-on nut 7 firmly pressed into its bore.
