Fishbone
to prevent furrows.
Der Antrieb von verticalen Walzen erfordert konische Zahnräder, welche gegen Bruch weniger sicher sind als Stirnräder und demselben hier in besonderer Weise ausgesetzt sind, weil -es fast unmöglich ist, die Geschwindigkeit am Umfange der Walzen genau entsprechend der stets zunehmenden des sich streckenden Stabes einzustellen. Dadurch wird der Stab zwischen den einzelnen Walzenpaaren entweder gezogen oder gestaucht und die auf die Walzen zu übertragende Kraft dementsprechend vergröfsert.The drive of vertical rollers requires conical gears, which against breakage are less safe than spur gears and are exposed to the same here in a special way are, because it is almost impossible, the speed at the circumference of the rollers exactly corresponding the ever increasing of the stretching rod. This places the rod between the individual pairs of rollers either pulled or compressed and the force to be transmitted to the rollers accordingly enlarged.
Im zweiten Falle geschieht das Drehen des Stabes in schraubenförmig ausgehöhlten Führungen, wozu ebenfalls viel Kraft erforderlich ist, so dafs dieses Verfahren nur bei kleinen Querschnitten, z. B. Walzdraht, anwendbar ist.In the second case, the rod is rotated in helically hollowed-out guides, for which a great deal of force is also required, so this procedure only applies to small ones Cross sections, e.g. B. wire rod, is applicable.
Um diese Uebelstände zu vermeiden, erhalten die verticalen Walzen A keinen Antrieb, sondern werden als sogen. Schleppwalzen eingerichtet. Die Streckung des Stabes wird denselben dann derartig zugemessen, dafs der Schub aus B und der Zug von B2 genügen, um A mitzutreiben. Dieses ist leicht zu erreichen, so lange der Stab noch einen grofsen Querschnitt hat; wird derselbe aber sehr klein, wie z. B. bei Drahtj dessen Metall noch sehr warm ist, so genügt der Zug von B2 allein nicht, und das Ende würde abreifsen, nachdem es B1 verlassen hat. Um dieses zu vermeiden , werden kleine Schwungräder C auf den verlängerten Zapfen derjenigen Walzen angebracht, welche die kleinen Furchen und daher auch die gröfste Geschwindigkeit haben. Da die dünnen Stäbe nicht genügende rückwirkende Festigkeit haben, um die Walzen mit den Schwungrädern beim Beginn des Betriebes in Gang zu setzen, so werden zu dem Zwecke Dampfrohre D in der. Nähe der Schwungräder angebracht, um die Inbetriebsetzung vermittelst des Dampfstromes nach der bekannten Art der Turbinen zu bewirken.In order to avoid these inconveniences, the vertical rollers A are not given a drive, but are called so-called Drag rollers set up. The stretching of the rod is the same then apportioned in such a way, the thrust of the train B and of B 2 DAF suffice A to flow along. This is easy to reach as long as the rod has a large cross-section; but it becomes very small, such as B. in the case of wire whose metal is still very warm, the pull of B 2 alone is not enough, and the end would wear off after it has left B 1 . In order to avoid this, small flywheels C are attached to the extended journals of those rollers which have the small furrows and therefore the greatest speed. Since the thin rods do not have sufficient retroactive strength to set the rollers with the flywheels in motion at the start of operation, steam pipes D in the. Attached near the flywheels in order to bring about the start-up by means of the steam flow according to the known type of turbines.
