Description

Die vorliegende Anmeldung betrifft eine Lagerung für einen Offenend Spinnrotor gemäß dem Oberbegriff von Anspruch 1 sowie ein Stützscheibenlager gemäß dem Oberbegriff des Anspruchs 13.The present application relates to a bearing for an open-end spinning rotor according to the preamble of claim 1 and a support disk bearing according to the preamble of claim 13.

Von der Rotorspinnmaschine RU14 SPINCOMAT (siehe Systemhandbuch Nr. 4 614) 16-0 der Firma Schubert & Salzer, jetzt Rieter Ingolstadt, D-85046 Ingolstadt ist es bekannt, die einzelnen Sektionen der Rotorspinnmaschine mit einem u-förmigen Träger auszustatten, in dessem Inneren die gattungsgemäße Lagerung des Spinnrotors mittels Stützscheiben untergebracht ist. Der Lagerbock, der die Stützscheibenlager aufnimmt, ist auf einer Trägerplatte montiert, die ihrerseits auf dem waagrechten Schenkel des u-förmigen Trägers angeschraubt ist. Für die Wartung des Lagers, insbesondere den Austausch der Stützscheiben, ist es erforderlich, den Lagerbock von der Trägerplatte oder diese vom u-förmigen Träger zu lösen und unter dem den Rotor antreibenden Tangentialriemen aus der Spinnmaschine herauszuziehen. Die Befestigung der Stützscheibenlager am Lagerbock erfolgt über eine Klemmvorrichtung, die die beiden Stützscheibenlager übergreift und diese in die Aufnahme am Lagerbock hineindrückt.From the RU14 SPINCOMAT rotor spinning machine (see system manual No. 4 614) 16-0 from Schubert & Salzer, now Rieter Ingolstadt, D-85046 Ingolstadt, it is known to equip the individual sections of the rotor spinning machine with a U-shaped carrier, inside of which the generic storage of the spinning rotor is accommodated by means of support disks. The bearing block, which receives the support disc bearings, is mounted on a support plate, which in turn is screwed onto the horizontal leg of the U-shaped support. For the maintenance of the bearing, in particular the replacement of the support disks, it is necessary to detach the bearing block from the carrier plate or this from the U-shaped carrier and to pull it out of the spinning machine under the tangential belt driving the rotor. The support disc bearings are fastened to the bearing block by means of a clamping device which overlaps the two support disc bearings and presses them into the receptacle on the bearing block.

Der Nachteil einer derartigen Lagerung besteht darin, daß die Wartung und Demontage der Lagerung, insbesondere der Austausch der Stützscheiben, sehr aufwendig ist. Nach dem Lösen der Befestigungsmittel der Trägerplatte oder der des Lagerbocks muß das Lager mit den Stützscheiben und dem am Lagerbock angeordneten Axiallager unter dem Tangentialriemen hindurch aus dem u-förmigen Träger herausgehoben werden. Ein Austausch der Stützscheiben ist erst am ausgebauten Lagerbock möglich. Durch die Art der Befestigung des Lagerbocks und auch der Trägerplatte am u-förmigen Träger ist es nicht möglich, diese nach Lösen nach unten zu bewegen, so daß der Lagerbock nicht unterhalb des Tangentialriemens herausgeführt werden kann. Aus der DE-A 36 22 523 ist eine ähnliche Rotorlagerung mittels Stützscheibenlager bekannt, bei der die Stützscheibenlager mittels einer Spannklammer von oben in ihre Aufnahmen gedrückt werden. Zum Ausbau der Stützscheiben muß die, nur von der Seite des Tangentialriemens schwer zugängliche Spannklammer, gelöst werden, was schwierig ist.The disadvantage of such storage is that the maintenance and disassembly of the storage, especially the exchange the support disks, is very complex. After loosening the fastening means of the carrier plate or that of the bearing block, the bearing with the support disks and the axial bearing arranged on the bearing block must be lifted out of the U-shaped carrier under the tangential belt. The support washers can only be replaced on the removed bearing block. Due to the nature of the mounting of the bearing block and also the carrier plate on the U-shaped carrier, it is not possible to move them downwards after loosening, so that the bearing block cannot be brought out below the tangential belt. From DE-A 36 22 523 a similar rotor mounting by means of support disk bearings is known, in which the support disk bearings are pressed into their receptacles from above by means of a tensioning clamp. To remove the support disks, the tension clamp, which is difficult to access only from the side of the tangential belt, has to be loosened, which is difficult.

Aufgabe der vorliegenden Anmeldung ist es, eine Lagerung für einen Offenendspinnrotor so auszugestalten, daß die Nachteile des Standes der Technik vermieden werden und die Lagerung einfacher gewartet und die Stützscheibenlager leichter montiert sowie demontiert werden können. Eine weitere Aufgabe ist es, ein Stützscheibenlager so auszubilden, daß dieses leichter an einem Lagerbock einer Lagerung für einen Offenend-Spinnrotor montiert werden kann.The object of the present application is to design a bearing for an open-end spinning rotor so that the disadvantages of the prior art are avoided and the storage is easier to maintain and the support disk bearings can be assembled and disassembled more easily. Another object is to design a support disk bearing so that it can be more easily mounted on a bearing block of a bearing for an open-end spinning rotor.

Die Aufgabe wird erfindungsgemäß durch die im Kennzeichen der Ansprüche 1 und 3 angegebenen Merkmale gelöst. Durch die erfindungsgemäße Ausgestaltung der Lagerung wird erreicht, daß die Stützscheibenlager und damit auch die Stützscheiben einfacher am Lagerbock der Lagerung befestigt werden können. Werden die Stützscheibenlager mit einem eigenen Befestigungsmittel versehen, ist es möglich, die Lagerung so auszugestalten, daß der Austausch der Stützscheibenlager einfacher vollzogen werden kann. Es ist nämlich möglich, die Stützscheibenlager ohne den Ausbau des Lagerbocks aus der Lagerung zu entfernen und sie auszutauschen, wozu die Aufnahme für die Stützscheibenlager eine Durchbrechung besitzt, durch die das Befestigungsmittel zugänglich ist. Dadurch ist es vorteilhaft möglich, die Stützscheibenlager von unten, d.h. von der dem Tangentialriemen des Lagers abgewandten Seite der Stützscheibenlagerung beispielsweise loszuschrauben und zu demontieren. Die Lagerung ist nämlich von unten wesentlich leichter zugänglich, da keine Antriebsmittel den Zugang zur Lagerung erschweren. Besonders günstig ist es, wenn das Befestigungsmittel am Stützscheibenlager als Bohrung ausgebildet ist, weil diese besonders vorteilhaft mit einem Gewinde versehen werden kann, so daß das Stützscheibenlager am Lagerbock beispielsweise mittels einer Schraube befestigt werden kann. Nach Entfernen dieser Schraube kann das Stützscheibenlager zusammen mit den Stützscheiben auf einfach Weise aus dem Lagerbock entnommen werden. Besonders günstig ist es, wenn die Stützscheibenlager eine einteilige Hülse besitzen, weil dadurch die Befestigung wesentlich erleichtert wird. Besonders günstig ist es, das Stützscheibenlager nur mit einem einzigen Befestigungsmittel zu versehen und dieses im wesentlichen mittig anzuordnen. Besonders vorteilhaft ist es, wenn der Lagerbock so ausgestaltet ist, daß dieser eine kompakte Einheit bildet, die im wesentlichen zwischen den Stützscheibenlagern angeordnet ist und seitlich an der Einheit im wesentlichen nur die Aufnahmen für die Stützscheibenlager angeordnet sind. Dadurch ist es möglich, die Stützscheiben zusammen mit ihren Lagern aus dem Lagerbock seitlich über den Lagerbock herauszuführen und aus diesem zu entnehmen. Eine Behinderung durch seitlich angeordnete Teile des Lagerbocks findet somit nicht statt. Die Stützscheiben können einfach aus dem Lagerbock entnommen werden. Besonders günstig ist es auch, den Träger für das Axiallager zwischen den Aufnahmen für die Stützscheibenlager am Lagerbock anzuordnen, wodurch auf seitlich neben den Stützscheiben befindliche Teile des Lagerbocks verzichtet werden kann, die für den Ausbau der Stützscheiben hinderlich wären. Weitere vorteilhafte Ausgestaltungen der Lagerung sind in den übrigen Unteransprüchen beschrieben.The object is achieved by the features specified in the characterizing part of claims 1 and 3. The configuration of the bearing according to the invention ensures that the support disk bearings and thus also the support disks can be more easily attached to the bearing pedestal of the storage. If the support disc bearings are provided with their own fastening means, it is possible to design the bearing so that the replacement of the support disc bearings can be carried out more easily. It is namely possible to close the support disc bearings without removing the bearing block from the bearing remove and replace them, for which purpose the support for the support disc bearings has an opening through which the fastener is accessible. As a result, it is advantageously possible to unscrew and disassemble the support disk bearings from below, that is to say from the side of the support disk bearing facing away from the tangential belt of the bearing. The storage is in fact much easier to access from below, since no drive means make access to the storage difficult. It is particularly favorable if the fastening means on the support disk bearing is designed as a bore, because this can be provided with a thread particularly advantageously, so that the support disk bearing can be attached to the bearing block, for example by means of a screw. After removing this screw, the support disc bearing together with the support discs can be easily removed from the bearing block. It is particularly expedient if the support disk bearings have a one-piece sleeve, because the attachment is thereby made considerably easier. It is particularly favorable to provide the support disk bearing with only a single fastening means and to arrange it essentially in the center. It is particularly advantageous if the bearing block is designed in such a way that it forms a compact unit which is arranged essentially between the support disk bearings and essentially only the receptacles for the support disk bearings are arranged on the side of the unit. Thereby it is possible to lead the support disks together with their bearings out of the bearing block laterally over the bearing block and to remove them from the latter. An obstruction by laterally arranged parts of the bearing block does not take place. The support disks can be easily removed from the pedestal. It is also particularly favorable to arrange the support for the axial bearing between the receptacles for the support disk bearings on the bearing block, as a result of which parts of the bearing block located laterally next to the support disks can be dispensed with, which would be an obstacle to the removal of the support disks. Further advantageous configurations of the storage are described in the remaining subclaims.

Durch die erfindungsgemäße Ausgestaltung des Stützscheibenlagers ist es möglich, dieses einfacher in einer Lagerung zu befestigen. Insbesondere bei der weiteren vorteilhaften Ausgestaltung, bei der das Befestigungsmittel in Form einer Bohrung ausgebildet ist, kann die Befestigung des Stützscheibenlagers mit genormten Bauteilen erfolgen, wodurch eine Lagerung für einen Offenend-Spinnrotor einfacher und kostengünstiger ausgebildet werden kann. Bei der erfindungsgemäßen Ausgestaltung des Stützscheibenlagers kann dieses auch gleichzeitig über das Befestigungsmittel zentriert in einer Lagerung für einen Offenend-Spinnrotor befestigt werden. Besonders günstig ist es, wenn das Befestigungsmittel als Bohrung ausgestaltet ist, die mit einem Gewinde versehen ist. Dadurch ist es möglich, das Stützscheibenlager mit einem einfachen Bauteil an einer Lagerung für einen Offenend-Spinnrotor tor festzuschrauben. Es ist auch vorteilhaft möglich, an der Stützscheibenlagerung einen Stift beispielsweise einen Gewindestift anzubringen, über den das Stützscheibenlager dann beispielsweise mit Hilfe einer Mutter an einem Lagerbock befestigt werden kann.The configuration of the support disk bearing according to the invention makes it possible to attach it more easily in a bearing. In particular in the case of the further advantageous embodiment, in which the fastening means is in the form of a bore, the support disk bearing can be fastened using standardized components, as a result of which storage for an open-end spinning rotor can be made simpler and less expensive. In the embodiment of the support disk bearing according to the invention, this can also be fastened in a bearing for an open-end spinning rotor, centered on the fastening means. It is particularly favorable if the fastening means is designed as a bore which is provided with a thread. This makes it possible to attach the support disk bearing to a bearing for an open-end spinning rotor using a simple component screw the gate. It is also advantageously possible to attach a pin, for example a threaded pin, to the support disk bearing, by means of which the support disk bearing can then be attached to a bearing block, for example with the aid of a nut.

Im Folgenden wird die Erfindung an Hand von zeichnerischen Darstellungen beschrieben.The invention is described below with the aid of drawings.

Die Lagerung für einen Offenend-Spinnrotor, das Rotorlager 1 von Figur 1, besteht aus dem Lagerbock 11, der Trägerplatte 12, den Stützscheiben 13, mit ihrem Stützscheibenlager 14 und dem Axiallager 15. Die Trägerplatte 12 ist an einer Stange 16 des Maschinengestells gelagert. Die Lagerung erfolgt über ein dämpfendes Element 162. Der Lagerbock 11 ist mittels einer Schraube 2 an der Trägerplatte 12 angeschraubt. Zentriert wird der Lagerbock 11 an der Trägerplatte 12 über Zentrierstifte in der Trägerplatte. Der Schaft 3 des Spinnrotors 30 liegt im Keilspalt von zwei Stützscheibenpaaren 13, von denen nur eines sichtbar ist. Der Rotor 30 befindet sich im Rotorgehäuse 4, das sich an der Stange 16 sowie an einer weiteren Halterung 161 abstützt. Das Rotorgehäuse ist dabei an der Halterung 161 eingeklipst. Der Lagerbock 11 trägt über den Träger 150 das Axiallager 15, das sich vorteilhafterweise seinerseits dämpfend an einer Abstützung 5 am Maschinengestell abstützt. Oberhalb des Rotorschaftes 3 ist der Tangentialriemen 6 für den Antrieb des Rotors sowie ein weiterer Tangentialriemen 61 für eine andere Rotorgeschwindigkeit angeordnet. Ebenfalls sichtbar ist eine Bremse 7.The bearing for an open-end spinning rotor, the rotor bearing 1 from FIG. 1, consists of the bearing block 11, the support plate 12, the support disks 13, with their support disk bearing 14 and the axial bearing 15. The support plate 12 is mounted on a rod 16 of the machine frame. The storage takes place via a damping element 162. The bearing block 11 is by means of a Screw 2 screwed to the support plate 12. The bearing block 11 is centered on the carrier plate 12 via centering pins in the carrier plate. The shaft 3 of the spinning rotor 30 lies in the wedge gap of two pairs of support disks 13, of which only one is visible. The rotor 30 is located in the rotor housing 4, which is supported on the rod 16 and on a further holder 161. The rotor housing is clipped onto the holder 161. The bearing block 11 carries the axial bearing 15 via the support 150, which is advantageously supported in a damping manner on a support 5 on the machine frame. The tangential belt 6 for driving the rotor and a further tangential belt 61 for a different rotor speed are arranged above the rotor shaft 3. A brake 7 is also visible.

Nach Entfernung des Rotors 30 und des Rotorgehäuses 4 kann der Lagerbock 11 von seiner Trägerplatte 12 durch Lösen der Schraube 2 gelöst werden. Durch axiales Verschieben des Lagerbocks in Richtung zum Rotorgehäuse wird das Axiallager 15 aus der Abstützung 5 herausgezogen. Abschließend kann der Lagerbock 11 nach unten abgesenkt werden, so daß er unterhalb des Tangentialriemens 6 und des weiteren Tangentialriemens 61 herausgezogen werden kann. Die Stützscheiben brauchen dazu nicht vom Lagerbock entfernt werden, weil genügend weit abgesenkt werden kann.After removal of the rotor 30 and the rotor housing 4, the bearing block 11 can be released from its support plate 12 by loosening the screw 2. The axial bearing 15 is pulled out of the support 5 by axially displacing the bearing block in the direction of the rotor housing. Finally, the bearing block 11 can be lowered so that it can be pulled out below the tangential belt 6 and the further tangential belt 61. The support disks do not need to be removed from the pedestal because they can be lowered far enough.

Besonders einfach können die Stützscheiben layer 14 im Rotorlager 1 von Figur 1 dadurch ausgetauscht werden, daß diese erfindungsgemäß mit einem als Bohrung 9 ausgebildeten Befestigungsmittel ausgestaltet sind. Dieses arbeitet mit einer Schraube 91 zusammen, die von unten durch die Aufnahme 111 hindurch in das Gewinde 60 der Bohrung 9 eingeschraubt ist. Zum Austausch der Stützscheiben 13 mit ihrem Stützscheibenlager 14 wird die Schraube 91 von unten, von wo das Rotorlager leicht zugänglich ist, gelöst. Wie aus Figur 3 besser zu ersehen ist, werden nach dem Lösen der Schrauben 91 die Stützscheibenlager aus der Aufnahme 111 angehoben und nach links und rechts seitlich über den Lagerbock 11 aus diesem herausgehoben. Dabei ist zwischen Lagerbock 11 und dem Tangentialriemen 6 genügend Platz für das Stützscheibenlager 14, so daß die Stützscheiben 13 ausgebaut werden können ohne daß die Spinnmaschine stillgesetzt werden muß. Es wird dazu lediglich normalerweise der Tangentialriemen 6 automatisch leicht angehoben, weil bereits vorher der Spinnrotor stillgesetzt wurde um ihn entfernen zu können. Durch die Bohrung 9 in Verbindung mit der Schraube 91 können die neu eingesetzten Stützscheibenlager auf einfache Weise im Lagerbock zentriert werden, ohne daß dazu die Lagerung von oben her zugänglich sein muß. Lediglich in besonderen Fällen bzw. wenn das Axiallager 15 ausgetauscht werden soll, wird der Lagerbock 11 durch Lösen der Schraube 2 von der Trägerplatte 12 gelöst und die gesamte Lagerung aus der Spinnmaschine entnommen. Auch für diesen Fall bewährt sich die erfindungsgemäße Ausgestaltung der Lagerung, denn durch das vorherige Entfernen der Stützscheiben kann der Lagerbock 11 nach vorne, nachdem das Rotorgehäuse 4 entfernt wurde, aus der Spinnmaschine herausgezogen werden.The support disks layer 14 in the rotor bearing 1 of FIG. 1 can be exchanged particularly simply by virtue of the fact that these are in accordance with the invention are designed with a fastener designed as a bore 9. This works together with a screw 91 which is screwed from below through the receptacle 111 into the thread 60 of the bore 9. To replace the support disks 13 with their support disk bearings 14, the screw 91 is loosened from below, from where the rotor bearing is easily accessible. As can be seen better from FIG. 3, after the screws 91 have been loosened, the support disk bearings are lifted out of the receptacle 111 and laterally lifted out of the bracket 11 to the left and right. There is enough space between the bearing block 11 and the tangential belt 6 for the support disk bearing 14 so that the support disks 13 can be removed without the spinning machine having to be stopped. For this purpose, the tangential belt 6 is normally only automatically raised slightly because the spinning rotor has already been stopped in order to be able to remove it. Through the bore 9 in connection with the screw 91, the newly inserted support disk bearings can be centered in the bearing block in a simple manner without the storage having to be accessible from above. Only in special cases or when the axial bearing 15 is to be replaced, the bearing block 11 is released from the carrier plate 12 by loosening the screw 2 and the entire bearing removed from the spinning machine. In this case, too, the configuration of the bearing according to the invention has proven itself, because by removing the support disks beforehand, the bearing block 11 can be pulled forward out of the spinning machine after the rotor housing 4 has been removed.

Figur 3 zeigt die Lagerung bei entferntem Rotorgehäuse. Daraus wird deutlich, daß der Lagerbock 11 nach Entfernung der Stützscheiben einfach aus der Spinnmaschine herausgenommen werden kann. Besonders günstig ist es dabei, wenn wie in Figur 1 gezeigt, das Axiallager aus seiner Abstützung 5 einfach herausgezogen werden kann, oder wenn, wie in Figur 2, das Axiallager 15 eigenständig am Maschinengestell 8 befestigt ist.Figure 3 shows the storage with the rotor housing removed. It is clear from this that the bearing block 11 can be easily removed from the spinning machine after the support disks have been removed. It is particularly advantageous if, as shown in FIG. 1, the axial bearing can simply be pulled out of its support 5, or if, as in FIG. 2, the axial bearing 15 is independently attached to the machine frame 8.

Bei der erfindungsgemäßen Lagerung nach Figur 2 kann der Lagerbock 11 besonders kurz ausgebildet werden, da die Abstützung des Axiallagers 15 direkt am Maschinengestell 8 erfolgt. Dadurch wird die Handlichkeit des Rotorlagers wesentlich verbessert, so daß dessen Ausbau viel leichter möglich wird. Nach dem Ausbau des Lagerbocks 11 oder auch nur der Stützscheiben 13, was im vorliegenden Ausführungsbeispiel ebenso wie bei Figur 1 erfolgt, ist der Zugang zum Axiallager 15 möglich. Besonders vorteilhaft ist die Kombination mit der erfindungsgemäßen Befestigung des Lagerbocks 11 an der Trägerplatte 12, so daß der Lagerbock 11 selbst leichter zu handhaben ist.2, the bearing block 11 can be made particularly short, since the axial bearing 15 is supported directly on the machine frame 8. This significantly improves the handiness of the rotor bearing so that it can be removed much more easily. After removal of the bearing block 11 or only the support disks 13, which takes place in the present exemplary embodiment as well as in FIG. 1, access to the axial bearing 15 is possible. The combination with the fastening of the bearing block 11 to the carrier plate 12 according to the invention is particularly advantageous, so that the bearing block 11 itself is easier to handle.

Figur 3 zeigt eine Vorderansicht einer erfindungsgemäßen Lagerung. Der Lagerbock 11 ist mittels der Schrauben 2 an der Trägerplatte 12 befestigt. Zentrierstifte 121 sorgen dafür, daß der Lagerbock zur Trägerplatte 12 exakt positioniert ist. Die Trägerplatte 12 ist an der Stange 16, die Teil des Maschinengestells ist, befestigt. Besonders günstig erfolgt dies hierbei über Dämpfungselemente 162. Das Axiallager wird am Maschinengestell 8, das in Form einer Stange ausgebildet ist, abgestützt. Die Stützscheibenlager 14 sind im Schnitt gezeigt, der durch die erfindungsgemäße Bohrung 9 gelegt ist. Über diese Bohrung 9 werden die Stützscheibenlager 14 von unten am Lagerbock 11 angeschraubt (vgl. Figuren 1 und 2).Figure 3 shows a front view of a bearing according to the invention. The bearing block 11 is fastened to the carrier plate 12 by means of the screws 2. Centering pins 121 ensure that the bearing block is positioned exactly with respect to the support plate 12. The support plate 12 is attached to the rod 16, which is part of the machine frame. Made particularly cheap this via damping elements 162. The axial bearing is supported on the machine frame 8, which is designed in the form of a rod. The support disk bearings 14 are shown in section, which is placed through the bore 9 according to the invention. The support disk bearings 14 are screwed onto the bearing block 11 from below via this bore 9 (see FIGS. 1 and 2).

Figur 4 zeigt ein erfindungsgemäß ausgestaltetes Stützscheibenlager 14. Die Hülse 143 enthält eine Bohrung 9, die im Schnitt dargestellt ist. Die Bohrung 9 ist mit einem Gewinde 60 ausgestattet zum Einschrauben einer Schraube 20 (siehe Fig. 2). Das Befestigungsmittel gemäß der Erfindung kann ebenfalls vorteilhaft als Bolzen, der im Rotorlager geklemmt wird oder als Gewindestift ausgebildet sein. Im letzten Fall erfolgt die Fixierung am Lagerbock beispielsweise mittels einer Mutter. Das Stützscheibenlager 14 besteht weiterhin aus einer Welle 141, die über nicht gezeigte Lager, z.B. Wälzlager, in der Hülse 143 gelagert ist. Die Welle besitzt Aufnahmen 142 an denen die Stützscheiben (siehe Fig. 1) angebracht werden.FIG. 4 shows a support disk bearing 14 designed according to the invention. The sleeve 143 contains a bore 9, which is shown in section. The bore 9 is equipped with a thread 60 for screwing in a screw 20 (see FIG. 2). The fastening means according to the invention can also advantageously be designed as a bolt which is clamped in the rotor bearing or as a threaded pin. In the latter case, the bracket is fixed, for example, using a nut. The support disc bearing 14 also consists of a shaft 141, which via bearings, not shown, e.g. Rolling bearing, is mounted in the sleeve 143. The shaft has receptacles 142 to which the support disks (see FIG. 1) are attached.
