Description

-An den Keilriemen sind die beiden Seitenflächen, also die Flächen, -die mit- den Keilriemenscheiben in Berührung kommen, im allgemeinen glatt, wie auch die Flächen der Keilriemenscheiben. Zur Übertragung der Antriebskräfte müssen die Riemen so weit gespannt werden, daß die Keilriemen in die Riemenscheiben eingepreßt sind. Die beiden Wellen bzw. Achsen der Antriebs- und getriebenen Scheibe werden dadurch erheblich belastet, und die Lager unterliegen einem dementsprechend hohen Verschleiß, während der Riemen gleichzeitig hoher Dehnungsbeanspruchung unterworfen ist.-On the V-belt are the two side surfaces, i.e. the surfaces -which come into contact with- the V-belt pulleys, generally smooth, like also the surfaces of the V-belt pulleys. To transmit the driving forces must the belts are tensioned so far that the V-belts are pressed into the pulleys are. The two shafts or axes of the drive and driven pulley are this is significantly burdened, and the bearings are subject to a correspondingly high Wear, while the belt is simultaneously subjected to high tensile stress is.

Der zum Patent angemeldete Keilriemen besitzt Seitenflächen, die mit einem Gleitschutz versehen sind, ähnlich dem gesommerten Profil der Personenwagenreifen. Die Seitenflächen erhalten zur Laufbahn des Riemens im rechten Winkel stehende Einschnitte, deren Tiefe und Abstand voneinander je nach dem Querschnitt des- Keilriemens i -bis io. mm betragen. Dadurch entstehen an beiden Seitenflächen Prismen.The V-belt, for which a patent has been applied, has side surfaces that are are provided with anti-skid protection, similar to the summer profile of passenger car tires. The side surfaces are cut at right angles to the belt's track, their depth and distance from each other depending on the cross-section of the V-belt i -bis ok mm. This creates prisms on both side surfaces.

In der Zeichnung ist ein Beispiel der Gegenstände der Erfindung dargestellt, und zwar zeigt Abb. i den Keilriemen mit dem auf beiden Seiten befindlichen Gleitschutzprofil von einer Seite- ,gesehen, Abb. a den Keilriemen mit Gleitschutz von der Schmalseite aus gesehen, Abb. 3 den Keilriemen bei schwerem Zug zwischen--zwei Riemenscheiben. -Das Einschneiden wirkt sich folgendermaßen aus: Bei schwerem Zug werden an der Antriebsseite die durch die Einschnitte entstandenen senkrecht stehenden Prismen.(Abb. 3) in der Drehrichtung der Antriebsscheibe a gezogen, die dadurch schräg gestellten Prismen verbreitern den Riemen und bewirken durch die Spreizstellung ein festeres Haften an den glatten Flächen der Keilriemenscheibe, während auf der getriebenen Seite b die Prismen in entgegengesetzter Richtung verstellt werden, weil diese Keilriemenscheibe durch den Arbeitsvorgang im entgegengesetzten Sinne der Antriebsscheibe a zieht. Das Durchzugsvermögen wird also auch bei weniger stramm angespanntem Keilriemen erreicht, wodurch eine erhebliche Schonung der Lager eintritt.In the drawing an example of the objects of the invention is shown, namely Fig. i shows the V-belt with the anti-skid profile on both sides seen from one side, Fig. a the V-belt with anti-slip protection from the narrow side seen from Fig. 3 the V-belt with heavy tension between - two pulleys. -The incision has the following effect: If the pull is heavy, the On the drive side, the vertical prisms created by the incisions (Fig. 3) pulled in the direction of rotation of the drive pulley a, which is thereby inclined Prisms widen the belt and, due to the spread position, create a firmer one Adhere to the smooth surfaces of the V-belt pulley while on the driven one Side b the prisms can be adjusted in the opposite direction because this V-belt pulley pulls through the operation in the opposite direction of the drive pulley a. The pulling power is also increased when the V-belt is less tightly tensioned achieved, whereby a considerable protection of the bearing occurs.

PATENTANSPRUCH: Keilriemen aus Gummi, Leder oder anderem Werkstöff, dadurch gekennzeichnet, daß die Seitenflächen im rechten Winkel zur Laufrichtung stehende Einschnitte aufweisen, die je nach der Stärke des Riemens z bis io mm tief und ebenso weit voneinander entfernt sind zu dem Zweck, den - Reibungskoeffizienten des Riemens zu erhöhen.PATENT CLAIM: V-belts made of rubber, leather or other materials, characterized in that the side surfaces are at right angles to the direction of travel have standing cuts which, depending on the thickness of the belt, are z to 10 mm deep and are just as far apart for the purpose of the - coefficient of friction to increase the belt.
