Description

Die Erfindung betrifft eine Spannvorrichtung für rohrförmige Wickelkerne, insbesondere von Papierbahnen oder ähnliche Werkstoffbahnen tragende Wickelkerne, bestehend aus mehreren in einem Käfig radial verstellbaren rohrsegmentförmigen Spannsegmenten, die um einen Zapfen herum angeordnet sind, zwischen dem und den Spannsegmenten Stützelemente vorgesehen sind, die in Umfangsnuten an der Zapfenoberfläche geführt sind, wobei der Zapfen im Bereich der Nuten einen gleichseitig-polygonalen Kernquerschnitt aufweist.The invention relates to a tensioning device for tubular winding cores, in particular winding cores carrying paper webs or similar material webs, consisting of several tubular segment-shaped tensioning segments which are radially adjustable in a cage and which are arranged around a pin, between which and the tensioning segments support elements are provided, which are provided in circumferential grooves of the pin surface, the pin having an equilateral polygonal core cross section in the area of the grooves.

Derartige Spannvorrichtungen sind z. B. aus der GB-PS 917 978 bekannt. Bei dieser bekannten Spannvorrichtung dienen Zylinderrollen als Stützelemente. Die Zylinderrollen rollen bei einer auf den Zapfen ausgeübten Drehbewegung einerseits auf den Grund der Umfangsnuten des Zapfens und andererseits auf der rohrförmigen Innenumfangsfläche der Spannsegmente ab, wodurch die Spannsegmente in radialer Richtung nach außen in die Spannstellung bzw. nach innen zurück in die Ausgangsstellung bewegt werden.Such clamping devices are such. B. known from GB-PS 917 978. In this known tensioning device, cylindrical rollers serve as support elements. The cylindrical rollers roll on a rotation on the pin on the one hand on the base of the circumferential grooves of the pin and on the other hand on the tubular inner circumferential surface of the clamping segments, whereby the clamping segments are moved radially outwards into the clamping position or inwards back into the starting position.

Als nachteilig hat sich bei dieser bekannten Spannvorrichtung der hohe Verschleiß erwiesen, der bei den auftretenden hohen Belastungen an Zapfen, Spannsegmenten und zylinderförmigen Stützelementen entsteht.The disadvantage of this known tensioning device has been the high wear that arises from the high loads that occur on the pins, tensioning segments and cylindrical support elements.

Aufgabe der Erfindung ist es nun, die gattungsgemäße Spannvorrichtung in der Weise zu verbessern, daß der an den gegeneinander beweglichen Teilen entstehende Verschleiß verringert wird.The object of the invention is to improve the generic clamping device in such a way that the wear on the mutually movable parts is reduced.

Zur Lösung dieser Aufgabe wird erfindungsgemäß bei der gattungsgemäßen Spannvorrichtung vorgeschlagen, daß die Stützelemente an ihrer den Spannsegmenten zugewandten Seite kugelförmig ausgebildet und in entsprechend halbkugelförmigen Vertiefungen in den Innenflächen der Spannsegmente eingelegt sind und an der dem Zapfen zugewandten Seite eine der Querschnittsform des Grundes der Nut angepaßte berührungsfläche besitzen.To solve this problem, it is proposed according to the invention in the generic tensioning device that the support elements on their side facing the tensioning segments are spherical and are inserted in corresponding hemispherical recesses in the inner surfaces of the tensioning segments and on the side facing the pin one of the cross-sectional shape of the base of the groove is adapted have contact area.

Aufgrund der erfindungsgemäßen Formgebung der Stützelemente wird an den Berührungstellen der Stützelemente mit den Spannsegmen en einerseits und der Stützelemente mit dem Zapfen andererseits eine flächige Anlage erreicht. Die gegeneinander beweglichen Teile, Spannsegmente, Stützelemente und Zapfen, haben also keine linienförmige Berührung wie bei der bekannten Spannvorrichtung sondern eine flächige, so daß die Flächenpressung geringer ist und dadurch der Verschleiß vermindert wird. Darüber hinaus ermöglicht es die erfindungsgemäße Ausbildung der Spannvorrichtung den Kernquerschnitt des Zapfens zu vergrößern und damit seine Belastbarkeit zu erhöhen. Diesem Zweck dient auch die bevorzugte im Querschnitt gesehen konvexe Krümmung des Grundes der Umfangsnuten im Zapfen, die zu einer Vergrößerung des Kernquerschnitts des Zapfens führt.Due to the shape of the support elements according to the invention, a flat contact is achieved at the points of contact of the support elements with the clamping segments on the one hand and the support elements with the pin on the other hand. The mutually movable parts, clamping segments, support elements and pins do not have a linear contact as in the known clamping device but a flat one, so that the surface pressure is lower and wear is reduced. In addition, the design of the tensioning device according to the invention makes it possible to enlarge the core cross section of the pin and thus to increase its resilience. This is also the purpose of the preferred, in cross-section, convex curvature of the base of the circumferential grooves in the pin, which leads to an enlargement of the core cross-section of the pin.

Die gemäß einer weiteren vorteilhaften Ausgestaltung der erfindungsgemäßen Spannvorrichtung vorgesehene konkave Ausformung des Grundes der Umfangsnuten in deren Längsschnitt gesehen verhindert einmal eine Kerbwirkung, die bei scharfkantigen Übergängen in den Nuten entstehen kann, und führt zu einer Erhöhung der Paßgenauigkeit bzw. läßt einen Ausgleich bei kleineren Fertigungsungenauigkeiten zu.The provided according to a further advantageous embodiment of the clamping device according to the invention, the concave shape of the bottom of the circumferential grooves in the longitudinal section prevents a notch effect that can occur in the grooves with sharp-edged transitions, and leads to an increase in the accuracy of fit or allows compensation for smaller manufacturing inaccuracies to.

Die in halbkugelförmigen Vertiefungen in den Spannsegmenten eingesetzten Stützelemente stützen das Spannsegment auch bei Verdrehung des Zapfens immer an der gleichen Stelle ab, so daß es nicht so leicht verkantet, als wenn wie bei der bekannten Spannvorrichtung das Stützelement sich bei Drehung des Zapfens auch gegenüber dem Spannsegment verlagern kann. Dabei bleibt die Kippbeweglichkeit des Spannsegments infolge der kugelgelenkartigen Verbindung mit dem Stützelement gegenüber dem Zapfen voll erhalten.The support elements used in hemispherical recesses in the tensioning segments always support the tensioning segment even when the pin is rotated, so that it is not tilted as easily as if, as in the known tensioning device, the support element also turns with respect to the tensioning segment when the pin rotates can shift. The tilting mobility of the clamping segment is fully preserved due to the ball joint-like connection with the support element relative to the pin.

Accordingly, the surface of the support elements 6 opposite the pin 7 is in the form of a circular arc with the radius r . (Figure 4) molded. Seen in the cross section of FIG. 1, the circumferential grooves 13 are convexly curved. The remaining core cross section of the pin 7 can be seen in Figure 1 by the oblique hatching.
