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.The 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 by against The self-adjusting tensioning rollers that are in contact with the slack part of the belt are regulated will.

Durch die Erfindung wird bezweckt, mittels nur einer Antriebsscheibe zwei getrenntThe aim of the invention is to separate two by means of only one drive pulley

ίο liegende Riemenscheiben gleichzeitig derartig anzutreiben, daß der Gang beider Riemen unabhängig voneinander durch schwingend gelagerte Spannrollen geregelt wird.ίο lying pulleys at the same time like this to drive that the gear of both belts independently of each other by swinging mounted Tension rollers is regulated.

In der Zeichnung ist eine Ausführungsform des Erfindungsgegenstandes dargestellt, und zwar zeigt Fig. 1 eine Ansicht und Fig. 2 eine teilweise im Schnitt dargestellte Draufsicht des Doppelriemenantriebes.The drawing shows an embodiment of the subject matter of the invention, namely, Fig. 1 shows a view and Fig. 2 is a partially sectioned plan view of the double belt drive.

α ist die auf dem freien Ende der Antriebswelle b sitzende Antriebsscheibe, auf welcher die beiden zu den anzutreibenden Riemenscheiben führenden Riemen e und f laufen. Auf dem in einer Wandplatte, Konsole o. dgl. befestigten Zapfen g sitzt die Hülse { des Tragarmes h der einen Spannrolle i, während die an dem Tragarm k der anderen Spannrolle m sitzende Hülse η auf der Hülse \ drehbar gelagert ist. Durch die Ineinanderlagerung der Hülsen \ und η wird eine sehr vorteilhafte und gedrängte Bauart der Spannvorrichtung erzielt. α is the drive pulley seated on the free end of the drive shaft b , on which the two belts e and f run, leading to the pulleys to be driven. The sleeve {of the support arm h of the one tensioning roller i sits on the pin g , which is fastened in a wall plate, bracket or the like , while the sleeve η , which is seated on the support arm k of the other tensioning roller m , is rotatably mounted on the sleeve \. A very advantageous and compact design of the clamping device is achieved through the interposition of the sleeves \ and η.

Die Spannrollen i und m liegen in bekannter Weise gegen das schlaffe Trum der Riemen e bzw. f an und sichern die nötige Riemenspannung.The tension rollers i and m are in a known manner against the slack strand of the belts e and f and secure the necessary belt tension.

Bei der dargestellten Ausführungsform des Doppelriemenantriebes isitzen die Spannrollen i und ra_auf den Wellen ο bzw. ρ, die zwischen den . durch die Querbolzen r bzw. s miteinander verbundenen Armen h und t bzw. k und u gelagert sind.In the illustrated embodiment of the double belt drive, the tensioning rollers i and ra_auf are seated on the shafts ο and ρ, which are located between the. arms h and t or k and u connected to one another by the cross bolts r and s are supported.

Claims (1)

Patent-Anspruch:Patent claim: Doppelriemenantrieb mit selbsttätiger Spannvorrichtung mittels gegen das schlaffe Trum der Riemen anliegender Spannrollen, dadurch gekennzeichnet, daß die zu den anzutreibenden Scheiben führenden Riemen (e, f) über eine gemeinsame Antriebsseheibe (a) laufen und die Tragarme (h, k) ihrer Spannrollen (i, m) mit ineinandergreifenden Hülsen fc, n) auf einem gemeinsamen Zapfen (g) gelagert sind.Double belt drive with automatic tensioning device by means of tensioning rollers resting against the slack strand of the belt, characterized in that the belts (e, f) leading to the pulleys to be driven run over a common drive pulley (a) and the support arms (h, k) of their tensioning rollers (i , m) with interlocking sleeves fc, n) are mounted on a common pin (g) .
