Description

Die Erfindung betrifft eine Einrichtung zum Sperren und Längslagern der Drällspindel in Pilgerschrittwalzwerken. Es sind solche Einrichtungen mit innerhalb des Gehäuses der Werkstück-Vorholvorrichtung auf der Drallspindel fest angeordnetem, unter Federdruck stehendem Sperrad und einer zur Drallspindel koaxial angeordneten, auf deren Stirnseite einwirkenden Abstützung bekannt.The invention relates to a device for locking and longitudinal storage the twist spindle in pilgrim step rolling mills. There are such facilities with within the housing of the workpiece pre-fetching device fixed on the twist spindle, ratchet wheel under spring pressure and one coaxially arranged to the twist spindle, known support acting on the end face.

Zur Lösung der Aufgabe, an einer solchen Einrichtung es zu ermöglichen, ohne großen Raumaufwand Sperriegel und Abstützung in einem Gehäuse unterzubringen, . das leicht abdichtbgr - am Werkstück-Vorholergehäuse angeflanscht werden kann, wird vorgeschlagen, das Sperrad als Tellerzahnrad auszubilden und die Sperriegel parallel zur Drallspindelachse verschiebbar sowie konzentrisch um die Abstützung der Drallspindelherum anzuordnen.To solve the problem of making it possible at such a facility, to accommodate locking bolt and support in one housing without taking up a lot of space, . which can be easily sealed - can be flanged to the workpiece pre-hauler housing, it is proposed to design the ratchet wheel as a ring gear and the locking bolt Can be moved parallel to the twist spindle axis and concentrically around the support to arrange the twist spindle around.

Die Verwendung eines Tellerzahnrades und die konzentrische Anordnung -einer größerezi Zahl von 'Sperriegeln ermöglichen den kleinsten Abstand zwischen Zahn des Rades und Sperriegel. Außerdem kommen dabei gleichzeitig mehrere Riegel und Zähne zum Tragen; dadurch wird die Bruchgefahr vermindert und das Anpilgern erleichtert.The use of a ring gear and the concentric arrangement -a larger number of 'locking bolts allow the smallest distance between Tooth of the wheel and locking bolt. In addition, several bars come at the same time and teeth for wear; this reduces the risk of breakage and pilgrimages relieved.

Bei der bekannten radialen raumfordernden Anordnung der Sperriegel sind nur wenige Riegel vorhanden, von denen im allgemeinen immer nur ein Riegel zum Tragen kommt. Das Sperrad hat dementsprechend starke Zähne, diese erfordern eine große Zahnteilung. Eine große Zahnteilung ergibt aber große Wege beim Sperren, erhöhte Bruchgefahr und erschwert das Anpilgern.In the known radial, space-consuming arrangement of the locking bolt there are only a few bars, of which generally only one bar is available comes into play. The ratchet wheel has correspondingly strong teeth, which require them a large tooth pitch. A large tooth pitch, however, results in large locking paths, increased risk of breakage and makes pilgrimages more difficult.

Eine vorteilhafte -weitere Ausbildung des Erfindungsgegenstandes besteht darin, daß die Abstützung als einstellbares Axiallager ausgebildet ist.There is an advantageous further development of the subject matter of the invention in that the support is designed as an adjustable axial bearing.

In der Zeichnung ist eine Ausführungsform der Erfindung im Längsschnitt dargestellt. Das Sperrad i ist auf das hintere Ende der Drallspindel2 aufgekeilt *und befindet sich innerhalb des Gehäuses. Die Zähne 3 des Sperrades und die Sperriegel 4 selbst stehen dabei axial zum Sperrad. Die Sperriegel sind in dem das Gehäuse der Werkstück-Vorholeinrichtung abschließenden Deckel 5 gelagert und stehen unter Federdruck 6, der durch Spannmutter 7 eingestellt werden kann. Der Pilgerdruck wird durch ein Axialkugellager 8 aufgenommen, das in einer Druckspindel g gelagert ist und durch Drehen derselben im zugehörigen Muttergewinde des Deckels auf das richtige Maß eingestellt werden kann.In the drawing, an embodiment of the invention is in longitudinal section shown. The ratchet wheel i is keyed onto the rear end of the twist spindle 2 * and is located inside the housing. The teeth 3 of the ratchet wheel and the locking bar 4 themselves are axially to the ratchet wheel. The locking bolts are in the housing the workpiece pre-fetching device closing cover 5 stored and are under Spring pressure 6, which can be adjusted by means of the clamping nut 7. The pilgrimage will added by an axial ball bearing 8 which is mounted in a pressure spindle g and by turning the same in the corresponding nut thread of the cover to the correct one Dimension can be adjusted.
