Description
Breitstreckwalze für WarenbahnenSpreader roller for webs of material
Die Erfindung betrifft eine Breitstreckwalze für Warenbahnen, wie Papier, Gewebe u.dgl.The invention relates to a spreader roller for webs of material, such as Paper, tissue and the like.
Derartige Breitstreckwalzen bestehen aus einer inneren, feststehenden, gebogenen Hohlwelle, auf der drehbar ein in W81zlagern gelagerter Mantel sitzt. Der Mantel besteht entweder aus einem mit Gummi oder anderem synthetischen Werkstoff überzogenen Stück oder aus mehreren, ringförmigen Teilen aus Metall, die mittels besonderer Muffen drehfest miteinander verbunden sind.Such spreader rollers consist of an inner, fixed, curved hollow shaft on which a rotatable jacket sits in roller bearings. The sheath consists either of a rubber or other synthetic material coated piece or of several, ring-shaped parts made of metal, which by means of special sleeves are non-rotatably connected to each other.
Der Mantel wird mit sehr hohen Drehzahlen angetrieben, so daß es vorkommen kann, daß er bei kritischen Geschwindigkeiten auf die feststehende Welle Erschfitterungen überträgt, die sich auf die übrigen mechanischen Bauglieder der Breitstreckwalze nachteilig auswirken. Starke frschfltterungen beeinflussen außerdem den einwandfreien Berrieb der Breitstreckwalze.The jacket is driven at very high speeds, so it happens can cause tremors on the stationary shaft at critical speeds transfers, which affect the other mechanical components of the spreader roll adversely affect. Strong feedings also affect the flawless one Abrasion of the spreader roller.
Aufgabe der Erfindung ist die Schaffung einer Vorrichtung für eine Breitstreckwalze der genannten Bauart, durch die die oben erwShnten Schwingungen gedämpft werden und die selbst einen möglichst einfachen und wirtschaftlichen Aufbau hat.The object of the invention is to provide a device for a Spreader roller of the type mentioned, through which the vibrations mentioned above are attenuated and the structure itself is as simple and economical as possible Has.
Zur Lösung dieser Aufgabe ist erfindungsgemäß eine Breitstreckwalze der beschriebenen Art so ausgebildet, daß in der feststehenden Hohlwelle ein mit ihrer Innenwandung in Wirkverbindung stehender, schwingungsdämpfender Körper eingebaut ist, der zumindest aus einem starren und einem elastischen Material zusanrmengesetzt ist.According to the invention, a spreader roller is used to achieve this object of the type described designed so that in the stationary hollow shaft with a Its inner wall is fitted with an operationally connected, vibration-damping body is composed of at least one rigid and one elastic material is.
Vorzugsweise sind die Teile des schwingungsdãmpfenden Körpers in der Hohlwelle koaxial zu dieser und zueinander eingebaut.Preferably, the parts of the vibration-damping body are in the Hollow shaft installed coaxially to this and to each other.
Weitere Merkmale und Vorteile der Erfindung ergeben sich aus der nachfolgenden Beschreibung der Zeichnung, die in einer einzigen Figur ein Ausführungsbeispiel der Erfindung zeigt.Further features and advantages of the invention emerge from the following Description of the drawing, in a single figure an embodiment of the invention shows.
Die erfindungsgemäße Breitstreckwalze besteht aus einer mittigen, feststehenden Hohlwelle 10, die auf herk5iinliche Weise mittels einer in der Mitte angeordneten Zugspindel 11 nach Belieben gebogen wird.The spreader roller according to the invention consists of a central, fixed hollow shaft 10, which in the conventional way by means of a in the middle arranged pull spindle 11 is bent at will.
Auf der Hohlwelle 10 sitzt ein walzenförmiger Mantel, der in dem dargestellten Beispiel aus mehreren ganzmetallischen rohrförmigen Teilen 12 besteht, die mittels elastischer Muffen 13 bekannter Art miteinander drehfest verbunden sind. Der Mantel kann jedoch auch einstückig aufgebaut und mit Gummi oder einem anderen Mhnlichen synthetischen Werkstoff überzogen sein. Der Mantel 12 ist über Wälzlager 14 drehbar auf der Hohlwelle 10 gelagert und mit einer Rillenscheibe 15 versehen, die von einem Antriebsmittel über einen Treibriemen angetrieben wird.On the hollow shaft 10 sits a roller-shaped jacket, which is shown in the Example consists of several all-metal tubular parts 12, which by means of elastic sleeves 13 of known type are rotatably connected to each other. The coat however, it can also be constructed in one piece and covered with rubber or something similar synthetic material coated. The jacket 12 can be rotated via roller bearings 14 mounted on the hollow shaft 10 and provided with a pulley 15, which is of a Drive means is driven via a drive belt.
Kennzeichnenderweise ist die erfindungsgemäße Breits treckwalze mit einem schwingungsdämpfenden Körper versehen. Er besteht aus einer Masse 16 aus einem Werkstoff, wie etwa Blei, die in der Mitte der Welle 10 auf der Zugspindel 11 koaxial zu dieser angeordnet ist und aus einer ringförmigen Masse 17, die zwischen der Masse 16 und der Innenwandung der Welle 10 eingeschoben ist.Characteristically, the wide stretching roller according to the invention is with provided with a vibration-damping body. It consists of a mass 16 of one Material, such as lead, in the center of the shaft 10 on the tension spindle 11 coaxially is arranged to this and from an annular mass 17, which is between the mass 16 and the inner wall of the shaft 10 is inserted.
Die Masse 17 bes.teht aus einem elastisch nachgiebigen, zum Dämpfen von Schwingungen geeigneten Werkstoff, wie Gummi oder dgl., welche Schwingungen schließlich in der Masse 16 und an der Zugspindel 11 abklingen. Es werden so lästige, sich während des Laufs des Hantels 12 bildende Geräusche vermieden. Gleichzeitig wird die Lebensdauer der mechanischen Bau-glieRer der Breitstreckwalze verlängert.The mass 17 consists of an elastically resilient one for damping Material suitable for vibrations, such as rubber or the like. Which vibrations finally decay in the mass 16 and on the tension spindle 11. It gets so annoying Noises formed during the movement of the dumbbell 12 avoided. Simultaneously the service life of the mechanical structural members of the spreader roll is extended.
Die Zeichnung zeigt eine mögliche Ausführungsform der Erfindung; selbstverständlich können an derselben Aenderungen vorgenommen werden, ohne dadurch den in den folgenden Patentansprüchen festgelegten Schutzbereich zu verlassen.The drawing shows a possible embodiment of the invention; Of course can be made to the same changes without affecting the following To leave the defined scope of protection.
