Description

Die vorliegende Anmeldung betrifft eine Dichteinheit für das Rotorgehäuse einer Offenend-Rotorspinnvorrichtung gemäß dem Oberbegriff des Patentanspruchs 1, insbesondere für die Wiederaufarbeitung von Offenend-Rotorspinnvorrichtungen mit einer Dichtung für das Rotorgehäuse gemäß dem Stand der Technik, beispielsweise wie in der DE 27 21 385 A gezeigt. Die in der DE-OS 27 21 385 gezeigte Dichtung (15) ist membranartig ausgebildet und über einen kurzen zylindrischen Steg mit einem verdickten Randwulst 16 verbunden. Diese Dichtung besteht aus Gummi oder einem gummieähnlichen Material. Die Dichtung weist eine topfartige Gestalt auf, so daß die Scheibe 15 in einem axialen Abstand zum Ringbund 19 des Spinnrotors 3 gehalten wird. Dabei entsteht eine Kammer 18 zwischen Ringbund 19 und Dichtung, die das Eindringen von Luft behindern soll. Der Nachteil dieser Vorrichtung ist, daß der Spinnrotor, um eine Dichtwirkung zu erzielen, einen in axialer Richtung ausgeprägten Bund besitzen muß.The present application relates to a sealing unit for the rotor housing an open-end rotor spinning device according to the preamble of the claim 1, in particular for the reprocessing of open-end rotor spinning devices with a seal for the rotor housing according to the prior art, for example as shown in DE 27 21 385 A. The seal (15) shown in DE-OS 27 21 385 is membrane-like and over a short cylindrical web with a thickened bead 16 connected. This seal is made of rubber or a rubber-like one Material. The seal has a pot-like shape, so that the disc 15 at an axial distance from the collar 19 of the spinning rotor 3 is held. This creates a chamber 18 between the collar 19 and Seal designed to prevent air from entering. The disadvantage of this The device is such that the spinning rotor, in order to achieve a sealing effect, has a must have a pronounced collar in the axial direction.

Um beispielsweise auch solche Spinnvorrichtungen des Standes der Technik mit höheren Drehzahlen betreiben zu können, ist es erforderlich, da moderne Spinnrotoren einen kürzeren axialen Bund besitzen müssen, eine andersartige Dichtung, die beispielsweise mit dem Schaft des Spinnrotors zusammenarbeitet, für das Rotorgehäuse vorzusehen. Bei bekannten Offenend-Spinnvorrichtungen, beispielsweise der Firma W. Schlafhorst & Co, ist die Dichtung für das Rotorgehäuse mit zwei Elementen, die zwischen sich die Wand des Rotorgehäuses einklemmen, befestigt und dadurch die Dichtung am Rotorgehäuse positioniert. For example, such spinning devices of the prior art To be able to operate at higher speeds, it is necessary because modern Spinning rotors must have a shorter axial collar, a different type Seal that works, for example, with the shaft of the spinning rotor, to be provided for the rotor housing. In known open-end spinning devices, for example from the company W. Schlafhorst & Co, is the Seal for the rotor housing with two elements between them Clamp the wall of the rotor housing, fastened and thereby the seal positioned on the rotor housing.

Aufgabe der vorliegenden Anmeldung ist es eine Dichteinheit für eine Offenend-Rotorspinnvorrichtung vorzuschlagen, mit deren Hilfe Spinnrotoren mit einem in axialer Richtung kleineren Bund auch an Rotorspinnmaschinen des Standes der Technik eingesetzt werden können, wodurch durch die geringere Eigenfrequenz derartiger Spinnrotoren die Rotordrehzahlen wesentlich erhöht werden können. Darüber hinaus soll eine Dichteinheit vorgeschlagen werden, die wartungsfreundlich ist und keine besonderen Ansprüche an die Befestigungsmöglichkeiten an der Maschine stellt.The object of the present application is a sealing unit for an open-end rotor spinning device to propose with the help of spinning rotors a smaller axial collar also on rotor spinning machines State of the art can be used, whereby the lower Natural frequency of such spinning rotors significantly increases the rotor speeds can be increased. A sealing unit is also proposed that is easy to maintain and has no special requirements for the Fastening options on the machine.

Die vorliegende Aufgabe wird erfindungsgemäß mit einer Dichteinheit gemäß den Merkmalen des Anspruchs 1 gelöst. Durch die erfindungsgemäße Dichteinheit wird bei deren Einsatz in Offenend-Rotorspinnmaschinen, insbesondere beim Aufbereiten bzw. Modernisieren von bereits im Betrieb befindlichen Maschinen, diese Maschinen deutlich verbessert. Dadurch können die Drehzahlen des Spinnrotors der Spinnmaschine wesentlich erhöht werden. Darüber hinaus wird auch eine deutliche Verbesserung der Wartungsfreundlichkeit erreicht, da eine verschlissene Dichtung wesentlich einfacher ausgebaut und durch eine neue ersetzt werden kann. Außerdem wird durch die erfindungsgemäße Ausgestaltung eine zuverlässigere Abdichtung des Rotorgehäuses erreicht. Es sind keine Arbeiten erforderlich um die Dichtung zu zentrieren, da dies selbständig in Folge ihrer schwimmenden Lagerung erfolgt. Durch die vertikale Unterstützung der Dichtscheibe mittels des Anschlags kann die Dichtscheibe, auch im Falle, daß kein Schaft eines Spinnrotors in die Dichtung eingesetzt ist nicht aus der Dichteinheit herausfallen. Dazu ist besonders vorteilhaft der Anschlag an der Trägerplatte angeordnet oder alternativ der Anschlag als Vorsprung am elastischen Element zur Halterung der Dichtscheibe ausgebildet.The present object is achieved according to the invention with a sealing unit solved the features of claim 1. Through the sealing unit according to the invention is used in particular in open-end rotor spinning machines when preparing or modernizing existing ones Machines, these machines improved significantly. This allows the Speeds of the spinning rotor of the spinning machine can be increased significantly. In addition, there will also be a significant improvement in maintainability achieved because a worn seal removed much easier and can be replaced with a new one. In addition, the Design according to the invention a more reliable seal of the rotor housing reached. No work is required to close the seal center, as this takes place automatically as a result of its floating storage. Through the vertical support of the sealing washer using the stop can the sealing washer, even in the event that there is no shaft of a spinning rotor inserted in the seal does not fall out of the sealing unit. For this purpose, the stop is particularly advantageously arranged on the carrier plate or alternatively the stop as a projection on the elastic element for holding the sealing washer.

Vorteilhaft ist der Trägerplatte eine Gegenscheibe zugeordnet, wodurch eine sichere und anpassungsfähige Befestigung der Dichteinheit an der Rotorspinnmaschine ermöglicht wird. Durch die vorteilhafte Ausbildung der Trägerplatte mit einem Durchmesser zwischen 35 mm und 75 mm wird ein universeller Einsatz der Erfindung bei verschiedensten Spinnmaschinen ermöglicht. Besonders günstig liegt der Durchmesser in einem Bereich zwischen 40 mm und 60 mm. Insbesondere in Kombination mit den vorteilhaften Abmessungen der Trägerplatte besitzt die Dichtscheibe vorteilhaft einen Durchmesser zwischen 34 mm und 60 mm, günstiger Weise zwischen 38 mm und 50 mm und besonders vorteilhaft zwischen 40 mm und 45 mm. Im folgenden wird die Erfindung Anhand von zeichnerischen Darstellungen erläutert.A support plate is advantageously assigned to the carrier plate, as a result of which a Safe and adaptable fastening of the sealing unit to the rotor spinning machine is made possible. Due to the advantageous design of the carrier plate with a diameter between 35 mm and 75 mm becomes a universal Use of the invention in a wide variety of spinning machines. The diameter is particularly advantageously in a range between 40 mm and 60 mm. Especially in combination with the advantageous dimensions the support plate advantageously has a sealing washer Diameter between 34 mm and 60 mm, favorably between 38 mm and 50 mm and particularly advantageously between 40 mm and 45 mm. in the The invention is explained below with the aid of drawings.

Figur 1 zeigt die erfindungsgemäße Dichteinheit sowie die mit dieser zusammenarbeitende Gegenscheibe 6. FIG. 1 shows the sealing unit according to the invention and the counter disk 6 cooperating with it.

Figur 2, Figur 3 und Figur 4 zeigen die Trägerplatte 10 in verschiedenen Darstellungen. Figur 2 in der Draufsicht, Figur 3 in der Seitenansicht und Figur 4 in räumlicher Darstellung. Figure 2, Figure 3 and Figure 4 show the carrier plate 10 in different representations. Figure 2 in plan view, Figure 3 in side view and Figure 4 in a spatial representation.

Figur 1 zeigt die Dichteinheit 1 gemäß der vorliegenden Erfindung, die aus einer Trägerplatte 10 besteht, die eine Dichtscheibe 2 trägt, die mittels eines elastischen Elementes 3 an der Trägerplatte 10 gehalten ist. Die Dichtscheibe 2 liegt dabei auf der Dichtkante 11 der Trägerplatte 10 auf. Die Dichtscheibe 2 wird an der Trägerplatte 10 mit Hilfe des elastischen Elements 3 gehalten. Das elastische Element 3 ist mittels eines Befestigungselements und mit Hilfe einer Distanzbuchse 31 gehalten und seinerseits an der Trägerplatte 10 befestigt. Die Ebene, in der die Dichtscheibe 2 liegt ist vertikal und senkrecht zum (nicht gezeigten) Schaft eines Spinnrotors ausgerichtet. Die Dichtscheibe 2 besitzt die Durchgangsbohrung 22, durch die hindurch im Betrieb der Schaft des Spinnrotors geführt ist. Die eigentliche Abdichtung zwischen Dichtscheibe 2 und dem Schaft des Spinnrotors erfolgt durch den geringen Spalt der sich zwischen dem Rotorschaft und der Begrenzung der Durchgangsbohrung 22 ergibt. Durch die schwimmende Lagerung der Dichtscheibe, das heißt, daß sich diese in ihrer Ebene senkrecht zum Rotorschaft auf der Dichtkante 11 frei bewegen kann, wird erreicht, daß sich die Dichtscheibe 2 im Verhältnis zum Rotorschaft selbständig zentriert. Ein Einstellen beim Einbau der Dichteinheit 1 durch das Wartungspersonal ist also nicht erforderlich. Zusammen mit den übrigen Merkmalen der Erfindung macht dies die Dichteinheit 1 besonders geeignet Rotorspinnmaschinen nachzurüsten und damit den Erfordernissen an eine moderne Offenend-Rotorspinnmaschine anzupassen, weil ein Einbau auch an einer Maschine erfolgen kann, die ursprünglich nicht dafür vorgesehen war und daher für den Einbau der Dichteinheit 1 keine Passflächen oder spezielle Befestigungsmöglichkeiten aufweist.Figure 1 shows the sealing unit 1 according to the present invention, which consists of a carrier plate 10, which carries a sealing washer 2, which by means of a elastic element 3 is held on the carrier plate 10. The sealing washer 2 lies on the sealing edge 11 of the carrier plate 10. The sealing washer 2 is on the carrier plate 10 by means of the elastic element 3rd held. The elastic element 3 is by means of a fastening element and held by means of a spacer bush 31 and in turn on the support plate 10 attached. The plane in which the sealing washer 2 lies is vertical and aligned perpendicular to the shaft (not shown) of a spinning rotor. The sealing washer 2 has the through hole 22 through which Operation of the shaft of the spinning rotor is performed. The actual seal between the sealing disc 2 and the shaft of the spinning rotor takes place through the small gap between the rotor shaft and the limit of the Through hole 22 results. Due to the floating bearing of the sealing washer, this means that these are in their plane perpendicular to the rotor shaft can move freely on the sealing edge 11, it is achieved that the sealing washer 2 independently centered in relation to the rotor shaft. A setting when installing the sealing unit 1 by the maintenance personnel is not required. Together with the other features of the invention this the sealing unit 1 particularly suitable to retrofit rotor spinning machines and thus the requirements for a modern open-end rotor spinning machine adapt because an installation also on a machine can take place that was not originally intended for and therefore for the installation of the sealing unit 1 no mating surfaces or special mounting options having.

Die Trägerplatte 10 besitzt unterhalb der Bohrung 4 eine Kante 5, auf der die Dichtscheibe 2 aufliegen kann, so daß sie die Trägerplatte 10 ohne ein Abheben des elastischen Elementes 3 durch eine Wartungsperson nicht verlassen kann. Die Kante 5 umfaßt vorteilhaft 90° bis ca. 250° des Umfangs der Trägerplatte 10. Aufgrund der bis zum Rand der Dichtscheibe 2 offenen ovalen Einkerbung 23 kann die Dichtscheibe 2 besonders vorteilhaft aus der Dichteinheit 1 ohne Werkzeug herausgenommen und wieder eingesetzt werden. Dazu muß lediglich das elastische Element angehoben werden.The carrier plate 10 has an edge 5 below the bore 4, on which the Sealing disc 2 can rest so that it supports the carrier plate 10 without lifting of the elastic element 3 by a maintenance person can. The edge 5 advantageously comprises 90 ° to approximately 250 ° of the circumference the carrier plate 10. Because of the open to the edge of the sealing washer 2 oval notch 23, the sealing washer 2 can be particularly advantageous from the Sealing unit 1 removed and replaced without tools become. All that needs to be done is to lift the elastic element.

Die Trägerplatte 10 arbeitet mit einer durchbrochenen Gegenscheibe 6 zusammen und ist mit dieser im montierten Zustand verschraubt. Zwischen der Gegenscheibe 6 und der Trägerplatte 10 wird die Wand des nicht gezeigten Gehäuses für den Spinnrotor eingeklemmt, so daß die vorgeschlagene Dichteinheit 1 am Rotorgehäuse fixiert ist. Gegenscheibe 6 und Trägerplatte 10 besitzen je eine Durchbrechung, deren Durchmesser wenigstens den Rotorschaft des Spinnrotors aufnehmen kann, vorteilhaft aber weit größer ausgebildet ist. Die Dichtscheibe 2 hingegen besitzt lediglich eine Durchbrechung, die wenig größer ist als der Durchmesser des Schaftes, den diese zu Dichtzwecken eng umschließt. Da die Dichtscheibe 2 über das elastische Element verschieblich an der Kante 5 der Trägerplatte 10 gehalten ist, zentriert der Rotorschaft (nicht gezeigt) die Dichtscheibe 2 selbsttätig.The carrier plate 10 works together with a perforated counter plate 6 and is screwed to it in the assembled state. Between the Counter plate 6 and the support plate 10, the wall of the not shown Housing for the spinning rotor clamped, so that the proposed Sealing unit 1 is fixed to the rotor housing. Counter plate 6 and carrier plate 10 each have an opening, the diameter of which is at least that Can accommodate the rotor shaft of the spinning rotor, but advantageously much larger is trained. The sealing disk 2, however, has only one opening, which is little larger than the diameter of the shaft that this is to Tightly encloses sealing purposes. Since the sealing washer 2 on the elastic Element is slidably held on the edge 5 of the support plate 10, centered the rotor shaft (not shown) the sealing disc 2 automatically.

Durch den Austausch der bekannten Dichtungen an Rotorgehäusen der bekannten Offenend-Spinnvorrichtungen wird erreicht, daß eine bessere Dichtwirkung erzielt wird und gleichzeitig eine Dichtung zur Verfügung gestellt wird, die es ermöglicht einen Rotor einzusetzen, dessen Bund, an dem der Rotor am Rotorschaft befestigt ist, in axialer Richtung des Rotorschaftes betrachtet kleiner auszubilden oder auf diesen ganz zu verzichten, weil am Rotorschaft selbst abgedichtet wird. Dadurch wird die Masse des Spinnrotors wesentlich verringert, wodurch erreicht wird, daß mit den Spinnvorrichtungen des Standes der Technik, nach deren Wiederaufarbeitung mit einer erfindungsgemäßen Dichteinheit 1, diese mit höheren Rotordrehzahlen betrieben werden können, weil ein masseärmerer Rotor eingesetzt werden kann, der ein günstigeres Schwingungsverhalten besitzt. Darüber hinaus ist die Dichtwirkung besser, wodurch die Spinnergebnisse und ebenso der Luftverbrauch der Offenend-Spinnvorrichtung verbessert wird.By replacing the known seals on rotor housings of the known Open-end spinning devices achieve better results Sealing effect is achieved and at the same time a seal is made available which makes it possible to use a rotor, the collar on which the rotor is attached to the rotor shaft, in the axial direction of the rotor shaft considered to be smaller or to do without them entirely because on Rotor shaft itself is sealed. This will make the mass of the spinning rotor significantly reduced, thereby achieving that with the spinning devices the prior art, after its reprocessing with an inventive Sealing unit 1, operated at higher rotor speeds can be because a low-mass rotor can be used, the has a more favorable vibration behavior. In addition, the sealing effect better, which results in the spinning results and also the air consumption the open-end spinning device is improved.
