Description
Es sind Keilriemen für Antriebszwecke mit trapezförmigem Querschnitt bekannt, die aus vulkanisiertem Kautschuk mit oder -ohne Umlage sowie aus einer Zugseele aus Baumwollgewebe oder Kordfaden oder einer Zugseele aus Metall bestehen. Auch die Anordnung !einzelner größerer, für sich, abgeschlossener Hohlräume ist bekannt, die dazu dient, den Riemen biegsam zu machen.There are V-belts for drive purposes with a trapezoidal cross-section known which Made of vulcanized rubber with or without a surcharge and a pull core made of cotton fabric or cord thread or a tension core made of metal. Also the arrangement ! individual, larger, self-contained cavities are known, which serve to to make the belt pliable.
Nach der Erfindung wird, um dem Keilriemen eine gleichmaßige Biegsamkeit zu geben, der Riemenkörper nicht wie bei bisher bekannten Riemen aus gewöhnlichem homogenem Kautschuk hergestellt, sondern er besteht, abgesehen von der Zugseele, auf der ganzen Riemenlänge, und zwar gleichmäßig in jedem Querschnitt, ganz oder teilweise aus Porenkautschuk, der mit vielen gas- oder luftgefüllten kleinen Hohlräumen versehen, ist und eine' Härte aufweist, die eine übermäßige Zusammendrückbarkeit verhindert. According to the invention, in order to give the V-belt a uniform flexibility give, the belt body is not made of ordinary homogeneous rubber as with previously known belts, but apart from the tension core, it exists evenly along the entire length of the belt in every cross-section, wholly or partly made of pore rubber, the one with many gas- or air-filled small cavities provided, and has a 'hardness that prevents excessive compressibility.
Es wird hierdurch, erreicht, daß alle aufeinanderfolgenden Querschnitte des Riemens beim Biegen sich infolge der gleichmäßig verteilten, in sich abgeschlossenen Hohlräume auch, gleichartig verhalten.It is thereby achieved that all successive Cross-sections of the belt when bending due to the evenly distributed, self-contained cavities also, behave in the same way.
Dadurch, daß beim Biegen die zusammengedrückte Unterseite des-Riemens sich in die Hohlräume einpressen kann, · werden Ausbauchungen dieser Unterseite vermieden und eine gleichmäßige Anpressung der Riemenflanken an die Flanken der Keilnutscheibe erzielt.The fact that when bending the compressed underside of the belt into the Can press in cavities, bulges on this underside are avoided and an even pressure of the belt flanks on the flanks of the keyway pulley achieved.
Die Zeichnung stellt Ausführungsbeispiele dar.The drawing shows exemplary embodiments.
Fig. ι zeigt den Querschnitt des Riemens, bei dem die Zugseele b in der Mitte liegt, wobei der obere TeE ß des Riemens aus gewöhnlichem und der untere Teil c aus Porenkautschuk besteht. Bei der Biegung des Riemens kann das gestauchte Material des unteren (schmäleren) Teiles in die Poren ausweichen, wobei sich diese durch Pressung des in ihnen befindlichen Gases mehr oder weniger schließen.Fig. Ι shows the cross section of the belt in which the tension core b is in the middle, the upper TeE ß of the belt consists of ordinary and the lower part c of pore rubber. When the belt is bent, the compressed material of the lower (narrower) part can move into the pores, whereby these close more or less by pressing the gas in them.
Fig. 2 zeigt eine Ausführungsform, bei welcher die an sich bekannte Zugseele b an der Oberseite des Riemens liegt und der untere Teil des Querschnittes aus Porenkautschuke besteht.Fig. 2 shows an embodiment in which the per se known tension core b lies on the upper side of the belt and the lower part of the cross section consists of pore rubbers.
Fig. 3 stellt eine Ausführungsform dar, bei welcher der unterhalb des Zugbandes b liegende TeE des Riemenkörpers aus gewöhnlichem Kautschuk α besteht, in welchen Porenkautschuk c keilförmig hineinragt.3 shows an embodiment in which the TeE of the belt body lying below the tension band b consists of ordinary rubber α , into which pore rubber c protrudes in a wedge shape.
