Abstract

The gearwheel is used to rotate the shaft, the force being transmitted by keys located in tangentially-opposed keyways; the new features are that part of the journal is tapered and a system of conical wedges is used on the end of the shaft. The shaft has a taper leading down to the parallel portion of the journal, and there is a matching taper is the bore of the gearwheel. The shaft terminates in a cylindrical projection of smaller dia. than the journal and a bush with a conical outer dia. is mounted on the projection. A recess is provided on the outside face of the gearwheel in which a second bush is fitted; this bush has a conical bore. The two bushes are used to push the gearwheel onto the conical taper on the shaft so that there is no play between wheel and shaft; the elimination of play in an important factor e.g. for converter-tilting mechanisms.

"Auf einem Wellenzapfen drehfest aufgestecktes Zahnrad großen Durchmessers""Large-diameter gear wheel non-rotatably attached to a shaft journal"

Die Erfindung betrifft ein auf einem Wellenzapfen drehfest aufgestecktes Zahnrad großen Durchmessers, wobei in einander etwa tangential gegenüberliegenden Längsnuten des Wellenzapfens und Längsnuten in der Bohrungsinnenwand des Zahnrades mehrere gleichmäßig auf den Umfang verteilte paßfederartige Elemente zur Übertragung der Umfangskraft vom Zahnrad auf den Zapfen vorgesehen sind.The invention relates to a gearwheel which is non-rotatably attached to a shaft journal large diameter, with approximately tangentially opposite longitudinal grooves of the shaft journal and longitudinal grooves in the inner wall of the bore of the gear several evenly distributed feather-key-like elements for transmitting the circumferential force from the gear to the pin are provided are.

Die Erfindung befaßt sich im besonderen mit den beispielsweise bei Konverterantrieben auftretenen Problemen, die in der Kraftübertragung vom Zahnrad großen Durchmessers, welches über mehrere mit ihm im Zahneingriff stehende Ritzel angetrieben wird auf den Konverterzapfen. Bei derartigen Kippantrieben für Stahlwerkskonverter treten sehr hohe Drehmomente auf. Eine besondere Schwierigkeit bereitet dabei das Aufpassen des Zahnrades auf den Wellenzapfen. Bei den auftretenden hohen Drehmomenten und den dauernd wechselnden Drehrichtungen ist ein genauer spielfreier Sitz erforderlich, der bei den heute bekannten hochentwickelten Fertigungsmethoden zwar herstellbar ist, der schließlich aber dazu führt, daß ein einmal auf den Wellenzapfen aufgesetztes Zahnrad nicht mehr oder unter nur großen Schwierigkeiten wieder vom Wellenzapfen gelöst werden kann.The invention is particularly concerned with, for example, converter drives problems that arise in the power transmission from the large diameter gear, which is in mesh with it over several The pinion is driven on the converter pin. With such tilt drives very high torques occur for steel mill converters. A particular difficulty is the fitting of the gear on the shaft journal. With the high torques that occur and the constantly changing directions of rotation a precise, play-free seat is required, which can be produced with the highly developed production methods known today, which ultimately but the result is that a gear wheel that has once been placed on the shaft journal is no longer released from the shaft journal, or only with great difficulty can be.

Aufgabe der Erfindung ist es, eine Verbindung zwischen dem Zahnrad und seinem Wellenzapfen zu schaffen, die eine spielfreie Verbindung des Zahnrades mit der Welle aufweist und trotzdem mit einfachen Mitteln wieder gelöst werden kann.The object of the invention is to provide a connection between the gear and to create his shaft journal, which has a backlash-free connection of the gear with the shaft and yet again with simple means can be solved.

Erfindungsgemäß wird daher vorgeschlagen, daß am Übergang zwischen dem zylindrischen Wellenzapfen und der Welle ein sich vom Zapfen zur Welle hin erweiternder Zwischenkonus vorgesehen ist und das Zahnrad auf seiner dem Zwischenkonus zugekehrten Seite eine dem Zwischenkonus angepaßte konische Erweiterung seiner Bohrung aufweist, daß am Wellenzapfen ein zapfenartiger zylindrischer Ansatz vorgesehen ist und daß das Zahnrad über einen in eine vordere Erweiterung der Bohrung eingepaßten Außenring mit Innenkonus und einen axial auf dem Ansatz verschiebbaren Innenring mit dem Ansatz verkeilt ist.According to the invention it is therefore proposed that at the transition between the cylindrical shaft journal and the shaft extends from the journal to the shaft widening intermediate cone is provided and the gear on its side facing the intermediate cone has a conical adapted to the intermediate cone Expansion of its bore has that a pin-like cylindrical projection is provided on the shaft journal and that the gear via one in a Front widening of the bore fitted outer ring with inner cone and an inner ring that is axially displaceable on the neck wedged with the neck is.

Es wird dadurch eine in einfacher Weise herstellbare spielfreie Verbindung zwischen dem Zahnrad und der Welle geschaffen, wobei darüber hinaus erhebliche fertigungstechnische Vorteile zu erwarten sind. Die beigefügten Abbildungen zeigen ein Ausführungsbeispiel der Erfindungen schematischer Darstellung. This creates a backlash-free connection that can be produced in a simple manner created between the gear and the shaft, in addition, significant manufacturing advantages are to be expected. The attached images show an embodiment of the inventions schematic representation.

The force transfer serve feather-key elements 10, arranged of the type shown in Figure 2 which is known for such purposes.

In Figur 1 ist ein auf einem Wellenzapfen 1 drehfest aufgestecktes Zahnrad 4 großen Durchmessers dargestellt, welches in der in Figur 2 dargestellten Art und Weise drehfest mit der Welle 2 bzw. dem Wellenzapfen 1 verbunden ist.In FIG. 1 there is a gear 4 that is non-rotatably attached to a shaft journal 1 Large diameter shown, which is rotatably connected in the manner shown in Figure 2 to the shaft 2 or the shaft journal 1.

Am Übergang zwischen dem zylindrischen Wellenzapfen und der Welle 2 ist ein sich vom Wellenzapfen 1 zur Welle 2 hin erweiternder Zwischenkonus 3 vorgesehen und das Zahnrad 4 weist auf seiner dem Zwischenkonus 3 zugekehrten Seite eine dem Zwischenkonus 3 angepaßte konische Erweiterung 6 seiner Bohrung 5 auf. Am Wellenzapfen 1 ist ein zapfenartiger zylindrischer Ansatz vorgesehen. Das Zahnrad 4 ist nun über einen in eine vordere Erweiterung der Bohrung 5 eingepaßten AußenringH mit Innenkonus und einen axial auf den Ansatz 8 verschiebbaren Innenring 7 mit Außenkonus mit dem Ansatz 8 verkeilt.
