Description

Die Erfindung bezieht sich auf eine beheizte Galette für Chemiefaser-Streckwerke od. dgl., insbesondere mit einem doppelten Mantel und einer Zwangsführung des im Ringraum zwischen den beiden Mänteln strömenden Wärmeträgers, und mit ehier stir.seitig an der Galette befestigten Lagerweüe, woje> in der Lagerwelle ein zentrisch gelagertes Rohr angeor^ net ist, innerhalb dieses Rohres der Wärmeträger zugeführt und im Ringraum um dieses Rohr der Wärmeträger abgeführt wird. Eine derartige Galette ist z. B. durch die DE-OS 18 16 001 bekannt.The invention relates to a heated godet for chemical fiber drafting devices or the like, in particular with a double jacket and a forced guidance of the flowing in the annular space between the two jackets Heat transfer medium, and with here stir. Side on the godet fortified Lagerweüe, woje> in the bearing shaft centrically supported tube is angeor ^ net within the heat transfer medium is supplied to this pipe and the heat transfer medium is removed in the annular space around this pipe will. Such a godet is z. B. from DE-OS 18 16 001 known.

Zwar wird mit diesen Galetten eine gleichmäßige Temperaturverteilung über den Galettenumfang erzielt, jedoch treten bei hohen Galettentemperaturen große Wärmeverluste auf, da u. a. über die Länge der Lagerwelle die Wärme des Wärmeträgers auf die durch das zur Schmierung der Lager der Lagerwelle notwendige öl übergeht.Although these godets achieve a uniform temperature distribution over the circumference of the godet, however, high heat losses occur at high godet temperatures because, among other things, over the length of the Bearing shaft the heat of the heat transfer medium on the through to the lubrication of the bearings of the bearing shaft necessary oil passes.

Daher liegt der Erfindung die Aufgabe zugrunde, Möglichkeiten zur Verringerung des Wärmeübergangs vom Wärmeträger im Bereich der Länge der Lagerwelle nach außen, also insbesondere an das Schmieröl, zu finden.The invention is therefore based on the object of finding ways to reduce the heat transfer from the heat transfer medium in the area of the length of the bearing shaft to the outside, in particular to the lubricating oil Find.

Erfindungsgemäß wird dies bei einer Galette der eingangs genannten Art dadurch erreicht, daß um das Rohr ein weiteres Rohr angeordnet ist, das sowohl im Abstand um das Rohr, als auch im Abstand von der Innenwandung der Lagerwelle, angeordnet ist. Wesentlich ist dabei die Wärmeisolierung zwischen dem zweiten Rohr und der Innenwand der Lagerwelle. Es reicht also nicht aus, lediglich ein zweites Rohr zur Führung des ablaufenden Wärmeträgers zu verwenden, vielmehr muß dies an seiner Außenseite gegenüber der Wandung der Lagerwelle wärmeisolierend sein. Am einfachsten erfolgt dies durch einen entsprechenden LuftspaltAccording to the invention, this is achieved in a godet of the type mentioned in that around the Another pipe is arranged, both at a distance around the pipe, as well as at a distance from the Inner wall of the bearing shaft is arranged. What is essential is the thermal insulation between the second tube and the inner wall of the bearing shaft. So it is not enough to just add a second pipe To use leadership of the expiring heat transfer medium, rather this must be on its outside opposite the Wall of the bearing shaft to be heat-insulating. The easiest way to do this is to use a corresponding one Air gap

Da der Raum zwischen dem zweiten Rohr -jnd der Lagerwelle zur Strömung vom Wärmeträger nichtSince the space between the second pipe -jnd the Bearing shaft to the flow of the heat carrier not

ίο benötigt wird, ist es zweckmäßig, zur Stabilisierung des Rohres hier Abstandshalter wie eine Hülse aus Keramik anzuordnen. Durch diese kann ein nachteiliger Wärmeübergang nicht bewirkt werden.
In der Zeichnung ist ein Querschnitt durch dieίο is required, it is advisable to arrange spacers here, such as a ceramic sleeve, to stabilize the tube. A disadvantageous heat transfer cannot be brought about by this.
In the drawing is a cross section through the

is erfindungsgemäß ausgebildete Galette als Ausführungsbeispiel dargestellt Die im Bereich der Verbindungsstelle mit ihrer Lagerwelle 1 gezeigte Galette 2 weist einen Außenmantel 3 und eine an dem Außenmantel 3 befestigte Stirnwand 4 auf. In einem geringen Abstandis according to the invention designed galette shown as an exemplary embodiment in the area of the connection point Galette 2 shown with its bearing shaft 1 has an outer jacket 3 and one on the outer jacket 3 attached front wall 4. At a short distance

?n vom Außenmantel 3 ist ein Innenmantel 5 auf der Stirnwand 4 befestigt Zwischen dem Außen- und dem Innenmantel befindet sich ein ringförmiger Raum 6, der in mehrere Kammern aufgeteilt und vom durch das zentrische Rohr 7 in der hohlen Lagerwelle 1 zugeführten Wärmemedium durchspült istFrom the outer jacket 3, an inner jacket 5 is attached to the end wall 4 between the outer and the Inner jacket is an annular space 6, which is divided into several chambers and from through the central tube 7 in the hollow bearing shaft 1 supplied heat medium is flushed

Die mit den aufgeschrumpften Lagern 9 und 10 gezeigte Lagerwelle 1 weist an der der Galette 2 zugekehrten Stirnfläche einen Befestigungsflansch 11 auf, der von Seiten der Stirnwand 4 der Galette 2 her mittels Schrauben 12 an der Galette 2 befestigt ist Der Befestigungsflansch weist in axialer und radialer Richtung Paßflächen auf. Die Paßflächen sind mit einer wärmeisolierenden Schicht 19, 20 versehen, durch die der für die Wärmeleitung nachteilige metallene Kontakt zwischen der Lagerwelle 1 und der Stirnwand 4 der Galette 2 gänzlich verhindert ist.The bearing shaft 1 shown with the shrunk-on bearings 9 and 10 points to that of the godet 2 facing end face on a fastening flange 11, which from the side of the end wall 4 of the godet 2 ago is fastened to the godet 2 by means of screws 12. The fastening flange points axially and radially Towards the mating surfaces. The mating surfaces are provided with a heat insulating layer 19, 20 through which the disadvantageous for the heat conduction metallic contact between the bearing shaft 1 and the end wall 4 of the Galette 2 is completely prevented.

Ein Wärmeverlust kann durch besondere Maßnahmen innerhalb der hohlen Lagerwdle, durch die der Wärmeträger zu- und abgeführt wird, verhindert werden. Dazu erstreckt sich nicht nur ein Rohr 7 durch die Lagerwelle 1, sondern zwei Rohre 7 und 21, von denen das äußere Rohr 21 das innere Rohr 7 mit Abstand umfaßt. Durch den damit geschaffenen Zwischenraum wird der Wärmeträger abgeführt, wie es aus dem eingezeichneten Pfeil zu entnehmen ist. Weiterhin ist auch zwischen dem äußeren Rohr 21 und der Innenmantelfläche der Lagerwelle 1 ein Zwischenraum freigelassen, damit auch hier ein metallener Kontakt mit der Lagerwelle 1 verhindert ist.Heat loss can be caused by special measures within the hollow bearing shaft through which the Heat transfer medium is supplied and removed, can be prevented. For this purpose, not only one pipe 7 extends through the bearing shaft 1, but two tubes 7 and 21, of which the outer tube 21, the inner tube 7 with Distance includes. Through the space created in this way, the heat transfer medium is carried away, as it is can be seen from the arrow drawn. Furthermore, is also between the outer tube 21 and the inner circumferential surface of the bearing shaft 1 left a gap free so that a metallic one here as well Contact with the bearing shaft 1 is prevented.

Der Abstand zwischen der Außenmantelfläche des äußeren Rohres 21 und der Innenmantelfläche der Lagerwelle 1 kann allein durch die exakte Lagerung der Rohre 7, 21 am Anfang und Ende der Lagerwelle 1 erzielt werden. Es ist jedoch auch möglich, dazu eine Hülse 22 vorzusehen, die ebenfalls aus einem wärmeisolierenden Material, wie Keramik, gefertigt sein sollte.The distance between the outer surface of the outer tube 21 and the inner surface of the The bearing shaft 1 can be supported solely by the exact mounting of the tubes 7, 21 at the beginning and end of the bearing shaft 1 be achieved. However, it is also possible to provide a sleeve 22, which is also made of a heat-insulating Material, such as ceramic, should be made.
