Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die Erfindung bezieht sich auf solche Riementriebe, bei welchen die Spannung des schlaffen Riementeiles und die Auflage des Riemens auf der Riemenscheibe durch gegen den schlaffen Riementeil anliegende, sich selbsttätig einstellende Spannrollen geregelt wird. Die Erfindung besteht darin, daß die mit feststehendem Ölbehälter versehene Spannrolle gegenüber ihrem Drehpunkt verstellbar angeordnet wird, um dadurch die Möglichkeit zu gewinnen, dieselbe Spannrollenlagerung mit gleichem Vorteil für Riemenscheiben verschiedenen Durchmessers verwenden zu können. Es ist nämlich für die ordnungsmäßige Arbeitsweise des Riementriebes erforderlich, daß die Spannrolle so nahe als möglich an die der Spannstelle benachbarte Riemenscheibe herangerückt wird, um den die Riemenscheibe umschlingenden Bogen des RiemensThe invention relates to such belt drives in which the tension of the slack part of the belt and the rest of the belt on the pulley the slack part of the belt is regulated, automatically adjusting the tensioning rollers. The invention consists in that the tensioning roller provided with a fixed oil container is arranged to be adjustable relative to its pivot point, thereby increasing the possibility win the same tension roller bearing with the same advantage for different pulleys To be able to use diameter. Namely, it is for the proper way of working of the belt drive, it is necessary that the tensioning pulley is as close as possible to the belt pulley adjacent to the tensioning point is moved closer to the arc of the belt wrapping around the pulley

ao möglichst zu vergrößern. Diese Wirkung wird für Riemenscheiben verschiedenen Durchmessers durch die vorliegende, verstellbare Spannrollenlagerung ermöglicht.ao as possible to enlarge. This effect is used for pulleys of different diameters made possible by the present, adjustable tension roller bearing.

Auf den Zeichnungen sind zwei Ausführungsformen des Erfindungsgegenstandes in Ansicht und in teilweise im Schnitt dargestellter Draufsicht veranschaulicht.In the drawings, two embodiments of the subject matter of the invention are shown in FIG View and illustrated in partially sectioned plan view.

Bei der in Fig. 1 und 2 dargestellten Vorrichtung wird das schlaffe Trum des über die Riemenscheibe α geführten Riemens b durch die Rolle c gespannt, deren Tragarm d um den Zapfen e schwingbar angeordnet ist und durch ein auf seinem freien Ende sitzendes Gewicht t beschwert sein kann. Die Laufachse^/ der Spannrolle«: ruht in der exzentrisch auf der Scheibe g angebrachten Lagerbüchse h. Die Scheibe g ist mit dem Tragarme d beispielsweise durch vier Schrauben i lösbar und verstellbar verbunden, so daß die Entfernung der Spannrolle c von ihrem Drehzapfen e durch Einstellung der Scheibe g veränderbar ist. - ·In the device shown in Fig. 1 and 2, the slack strand of the belt b guided over the pulley α is tensioned by the roller c , the support arm d of which is arranged to swing around the pin e and weighed down by a weight t sitting on its free end can. The running axis ^ / of the tensioning pulley «: rests in the bearing bush h, which is eccentrically attached to the disk g. The disk g is detachably and adjustably connected to the support arm d, for example by four screws i , so that the distance of the tensioning roller c from its pivot e can be changed by adjusting the disk g . - ·

Die Veränderbarkeit der Entfernung der Spannrolle c von ihrem Drehpunkte wird bei der Ausführungsform nach Fig. 3 und 4 dadurch erreicht, daß der Tragarm d gegenüber dem Drehzapfen e mittels in dem Arme vorgesehener Schlitzführungen m verstellbar angeordnet ist. Der Tragarm d wird in seiner jeweiligen Lage durch in den Zapfen e eingeschraubte Stellschrauben η festgestellt, welche in die Führungen m eingreifen.The variability of the distance of the tension roller c from its pivot points is achieved in the embodiment according to FIGS. 3 and 4 in that the support arm d is arranged to be adjustable relative to the pivot e by means of slot guides m provided in the arm. The support arm d is fixed in its respective position by adjusting screws η which are screwed into the pin e and which engage in the guides m.

Natürlich kann die Verstellbarkeit der Spannrolle c gegenüber ihrem Drehpunkte auch durch andere Mittel erreicht werden. Beispielsweise kann die exzentrische Lagerung nach Fig. 1 und 2 auch am Drehzapfen e und umgekehrt die Schlitzführung nach Fig. 3 und 4 auch für die Lagerung der Spannrolle selbst vorgesehen werden.Of course, the adjustability of the tensioning roller c with respect to its pivot point can also be achieved by other means. For example, the eccentric mounting according to FIGS. 1 and 2 can also be provided on the pivot e and, conversely, the slot guide according to FIGS. 3 and 4 can also be provided for mounting the tensioning roller itself.
