Abstract

PCT No. PCT/EP88/00018 Sec. 371 Date Oct. 5, 1988 Sec. 102(e) Date Oct. 5, 1988 PCT Filed Jan. 12, 1988 PCT Pub. No. WO88/05478 PCT Pub. Date Jul. 28, 1988.A drive for the guide roll of a drying felt or wire in the drying group of a paper machine, or the like. A gear transmission drives a selected one of the paper web guide rolls, which may be a drying cylinder, in a first group of rolls. The felt or wire is wrapped around a second group of rolls comprising felt or wire guide rolls. The one felt or wire guide roll located nearest the gear transmission is connected to the shaft of a drive gear of the gear transmission via a belt drive connection. Thus, rotation of the drive gear of the gear transmission via the gear transmission drives the one selected driven roll of the first group, and via the belt drive connection drives the driven felt or wire guide roll.

Description

Antrieb einer FilzleitwalzeDrive of a felt guide roller
Die Erfindung betrifft einen Antrieb einer Filzleitwalze einer Trockengruppe von Papiermaschinen. In einer Trockengruppe be¬ steht am Ende derselben oft ein höherer Bahnzug als in den vor¬ angehenden Papierzügen, wo die Papierbahn noch feuchter ist. Im allgemeinen umschlingt ein Filz oder Sieb zusätzlich die Papier¬ führungswalzen der Trockengruppe zusammen mit der Papierbahn, um diese zu trocknen und zu führen. Damit diese Führungseigenschaft gewährleistet bleibt und der Filz die Papierbahn nicht bremst und die Haftreibung an den Papierführungswalzen aufhebt, muß eine möglichst genau gleiche Geschwindigkeit von Filz und Pa¬ pierbahn gewährleistet sein. Es empfiehlt sich daher ein Antrieb des Filzes oder Siebes, insbesondere durch eine Filz- oder Sieb¬ leitwalze. Denkbar ist es hier, eigene Elektromotoren für einen solchen Antrieb vorzusehen. Es ist jedoch sehr teuer und es ist schwierig, den genauen Gleichlauf von Filz und Papierbahn herzu¬ stellen. Die Lösung dieser Aufgabe gelingt erfindungsgemäß durch die Merkmale des kennzeichnenden Teils des Schutzanspruchs 1.The invention relates to a drive of a felt guide roller of a drying group of paper machines. At the end of a drying group there is often a higher web draw than in the preceding paper draws, where the paper web is even wetter. In general, a felt or sieve additionally wraps around the paper guide rollers of the drying group together with the paper web in order to dry and guide it. In order for this guiding property to be guaranteed and for the felt not to brake the paper web and to remove the static friction on the paper guide rollers, the same possible speed of the felt and paper web must be ensured. It is therefore advisable to drive the felt or screen, in particular by means of a felt or screen guide roller. It is conceivable here to provide separate electric motors for such a drive. However, it is very expensive and it is difficult to establish the exact synchronization of the felt and paper web. This object is achieved according to the invention by the features of the characterizing part of protection claim 1.
Es hat sich herausgestellt, daß mit dieser Lösung ein sehr guter Gleichlauf auch bei Bahnbeschleunigungen erreichbar ist.It has been found that with this solution very good synchronism can also be achieved with path accelerations.
In den Figuren ist ein Ausführungsbeispiel der Erfindung darge¬ stellt, und zwar zeigtIn the figures, an embodiment of the invention is shown, namely shows
Fig. 1 prinzipmäßig Bahn- und Filzführung und Fig. 2 eine Draufsicht, zum Teil im Schnitt, des Bereichs, wo das Getriebe, die angetriebene Papierleitwalze und die Filzleitwalze sich befinden.Fig. 1 in principle web and felt guide and Fig. 2 is a plan view, partly in section, of the area where the gear, the driven paper guide roller and the felt guide roller are located.
In Fig. 1 ist das Ende der Trockengruppe prinzipmäßig darge¬ stellt, wo die doppelpunkt-strichliert angedeutete Papierbahn über die Leitwalzen 1, 21, 22 und 41 geführt ist, wovon Leitwal¬ ze 1 über strichpunktiert mit ihrem Teilkreis dargestellte Zahn¬ räder 9, 10 und 11 eines Vorgelegegetriebes angetrieben ist. Die Filzleitwalzen sind mit 2, 31, 32, 33 und 34 bezeichnet. Der Filz ist strichpunktiert angedeutet. Dabei ist die dem Getriebe bzw. der von diesem angetriebenen Papierleitwalze 1, die auch eine Trocknungswalze sein kann, am nächsten gelegene Filzleit¬ walze 2 des oberen Trumms des Filzes über Riemenscheiben 13 und 14 und Riemen 15 von der Welle 12 des Antriebsritzels 11 des Vorgelegegetriebes 6 angetrieben, wie näher aus Fig. 2 her¬ vorgeht. Es kommt natürlich auch eine Filzleitwalze des unteren Filztrums und die Welle eines anderen Getrieberades für den An¬ trieb in Frage. Es befindet sich dabei die Riemenscheibe 14 der Filzleitwalze 2 zwischen dieser und ihrem Lager 8. Hier ist noch das linke Lager 4 der angetriebenen Papierleitwalze 1 angedeutet,In Fig. 1, the end of the drying group is shown in principle, where the double-dashed paper web is guided over the guide rollers 1, 21, 22 and 41, of which guide roller 1 via toothed wheels 9 shown in dash-dot lines with their pitch circle, 10 and 11 of a countershaft gear is driven. The felt guide rollers are designated 2, 31, 32, 33 and 34. The felt is indicated by dash-dotted lines. The felt guide roller 2 of the upper run of the felt via pulleys 13 and 14 and belts 15 of the shaft 12 of the drive pinion 11 of the countershaft transmission is the closest to the gear mechanism or the paper guide roller 1 driven by the latter, which can also be a drying roller 6 driven, as follows from FIG. 2. Of course, there is also a felt guide roller of the lower felt strand and the shaft of another gear wheel for the drive. There is the pulley 14 of the felt guide roller 2 between it and its bearing 8. Here, the left bearing 4 of the driven paper guide roller 1 is also indicated,
Der Riemen kann sowohl glatt (flach) als auch als ein Viel¬ keil- oder Mehrkeilriemen ausgebildet sein.The belt can be designed to be both smooth (flat) and as a multi-V or multi-V belt.
Die geschilderte Antriebsart ist recht einfach aufgebaut, arbei¬ tet sehr genau und daher voll zufriedenstellend. The type of drive described is of quite simple construction, works very precisely and is therefore completely satisfactory.
