Reibradantrieb»Friction wheel drive »
Bei Trommelmühlen (Kugelmühlen), Trommelmischern, Trommelofen und ähnlichen srommelförmigen Einrichtungen ist es üblich, den Trommellcörper mit glatten Laufringen auszurüsten, die über seine Länge verteilt sind* Meist begnügt man sich, mit je einem Laufring in der Nähe der beiden Enden der Trommel. Jeder Laufring läuft auf zwei Stützrollen* Zum Antrieb der Trommel dient entweder ein auf ihr angebrachter Zahnkranz, der mittels Ritzel angetrieben wird, oder es werden die Stützrollen zum Antrieb benutzt» Im letzteren Falle spricht man von einem Reibradantrieb, Um die notwendige Reibung zu erhalten, muß mindestens je eine der beiden Stützrollen jedes Laufringes angetrieben werden. In der Regel geschieht das mit Hilfe einer parallel sur Trommel gelagerten Antriebswelle, die die als Treibrollen dienenden Stützrollen antreibt.In the case of drum mills (ball mills), drum mixers, drum furnaces and similar drum-shaped devices, it is common to to equip the drum body with smooth running rings that are distributed over its length * Most of the time, one is content with one running ring near each end of the drum. Each race runs on two support rollers * To drive the The drum either has a toothed ring attached to it, which is driven by a pinion, or the Support rollers are used for the drive »In the latter case one speaks of a friction wheel drive. In order to obtain the necessary friction, at least one of the two support rollers of each race must be driven. Usually this happens with With the help of a drive shaft mounted parallel to the drum, which drives the support rollers that serve as drive rollers.
Diese Antriebe zeigen in der Praxis den Nachteil, daß sie sie sich ungleichmäßig abnutzen, so doR die Treibrollen und die Laufringe in der Abwicklung nicht mehr übereinstimmen. Besonders in staubigen Betrieben trit"c dieser (!beistand sehr bald auf. Die Folge dieser ungleichmäßigen Abnutzung bei starrer Kupplung der Treibrollen ist ein erheblicher Kraftverlust, Erwärmung, Verschleiß der Laufflächen infolge Reibung, Im Betrieb fengen die Mühlen und dgl, an zu vibrieren und auf den Laufflächen der Laufringe bzw= ihrer Bandagen entstehen rauhe Stellen und Zittermarken,,In practice, these drives have the disadvantage that they wear out unevenly, so that the drive rollers and the races no longer match in the development. Especially in dusty factories trit "c this (! Backer much to soon. The result of this uneven wear on a rigid coupling of the drive rollers is a significant loss of power, heat, wear of the bearing surfaces due to friction, in operation fengen the mills and the like, vibrate to and Rough spots and tremors appear on the running surfaces of the races or their bandages.
Die Erfindung vermeidet diesen" übelstand dadurch, daß die Treibrollen nicht starr miteinander verbunden sind, sondern durch Anwendung von Different!al-Antrieben zwischen den Treibrollen oder durch getrennte Antriebe jedes einzelnen Antriebsrades mit unterschiedlicher Drehzahl angetrieben werden können*The invention avoids this "disadvantage" in that the drive rollers are not rigidly connected to one another, but rather by using differential drives between the drive rollers or by using separate drives for each individual drive wheel can be driven at different speeds *
Die Erfindung ist in der Zeichnung an Hand von zwei Ausführungsbeilspielen sur Darstellung gebracht.The invention is shown in the drawing on the basis of two exemplary embodiments.
