Abstract

The invention is a round toothed belt, consisting of a flexible continuous strand, on which profiles are arranged at regular intervals which are round, rectangular, trapezoidal, elliptical or triangular in the transverse direction. In the longitudinal direction of the continuous strand, the previously mentioned shapes repeat. It is an elastic drive belt, from which the drive movement is taken off all around by means of pinions, item 9, from the longitudinal movement of the round toothed belt. From the triangular Figure 4, a narrow pinion emerges for the construction, which can transmit a great torque via the toothed belt. Round toothed belts are known with inner and outer profiles in flat rectangular form or with round cross-section where two diametrically opposite round profiles with a round cap are mounted. The aim of the invention consists in improving the round toothed belt, which is described in the first paragraph, to the extent that, from a straight transport direction, a transversely directed transport direction up to 160 degrees can be driven. As a result of the all-around toothing, the rotary movement can be taken off from the round toothed belt by means of pinions, item 9, in any angular positions. To achieve the aim, design features, which are to an extent known, are envisaged, for example that the bead mounted all around the profile is made from the same material (rubber or plastic). In production lines, it is for example necessary that the supply belt to the machine ... Original abstract incomplete. <IMAGE>

Description

Die Erfindung ist ein Zahnrundriemen, bestehend aus einem biegsamen endlosen Strang, an dem in gleichmäßigen Abständen in Querrichtung rund, rechteckig, trapezförmig, elipsenförmig oder dreieckige Profile. In Längsrichtung des endlosen Stranges wieder holen sich vorher genannte Formen.The invention is a toothed belt, consisting of a flexible endless strand on which at even intervals in the transverse direction round, rectangular, trapezoidal, elliptical or triangular profiles. In the longitudinal direction of the endless strand again get previously mentioned shapes.

Es ist ein elastischer Treibriemen, von dem Rundum mittels Zahn ritzel Pos. 9, die Drehbewegung aus der Längsbewegung des Zahn rundriemens abgenommen wird.It is an elastic drive belt, from all around by means of a tooth pinion pos. 9, the rotary movement from the longitudinal movement of the tooth round belt is removed.

Aus der dreieckigen Fig. 4 ergibt sich für die Konstruktion ein schmales Zahnritzel, welches über den Zahnriemen ein hohes Dreh moment übertragen kann.From the triangular Fig. 4 there is a narrow pinion for the construction, which can transmit a high torque via the toothed belt.

Bekannt sind Rundzahnriemen mit innen und Außenprofile in flacher rechteckiger Form, oder mit rundem Querschnitt wo zwei diametral gegenüberliegende Rundprofile mit runder Kuppe aufgesetzt sind.Round toothed belts with inner and outer profiles in flat are known rectangular shape, or with round cross-section where two diametrically opposite round profiles with a rounded top are placed.

Die Aufgabe der Erfindung besteht darin, das der Zahnrundriemen der im ersten Abschnitt beschrieben ist, insoweit so zu verbes sern, das aus einer geradeaus Transportrichtung eine quergerich tete Transportrichtung bis 160 Grad angetrieben werden kann. Durch die rundum Verzahnung, kann mittels Ritzel Pos. 9 in allen Winkellagen die Drehbewegung vom Rundzahnriemen abgenommen wer den.The object of the invention is that of the toothed belt which is described in the first section, so far so verbes sern, which from a straight forward direction of transport a transverse dish can be driven up to 160 degrees. Due to the all-round toothing, pinion 9 can be used in all Angular positions, the rotary movement of the toothed belt who removed the.

Zur Lösung der Aufgabe sind teilweise bekannte Gestaltungsmerk male vorgesehen, das der um das Profil rundum aufgesetzte Wulst aus dem selben Material (Gummi oder Kunststoff) ausgebildet ist. Bei Fertigungsstraßen ist zum Beispiel erforderlich, das das Zu bringerband zur Maschine synchron laufen muß, durch Motore und Elektronik wird das Heute erreicht. Mittels Zahnrundriemen kann der 90 Grad Winkelantrieb diese Synchronität beim kurzen Trans portband erstellen.To solve the problem, some well-known design features Male provided that the bead placed all around the profile is made of the same material (rubber or plastic). In the case of production lines, for example, it is necessary to do this Bringerband must run synchronously to the machine, by motors and Electronics is achieved today. With a toothed belt the 90 degree angular drive ensures this synchronicity in the short trans create portband.

Das Profil Fig. 2 bis 8 hat auch einen weiteren Vorteil, das bei Verschleiß der Zahnrundriemen gedreht werden kann.The profile Fig. 2 to 8 also has another advantage that the toothed belt can be rotated when worn.

Besonders hervorzuheben ist das der Zahnrundriemen durch die im Zahnritzel Pos. 9 ausgearbeitete Form, durch Achsversatz der Rit zel gegeneinander, der Zahnrundriemen immer mittig in das Ritzel läuft.Particularly noteworthy is the toothed belt through the in Pinion pos. 9 elaborated shape, through offset of the rit against each other, the toothed belt always in the center of the pinion running.

Die Erfindung wird in einem Ausführungsbeispiel an Hand der Zeich nung erläutert.The invention is in one embodiment with reference to the drawing explained.
