Definitions
- the invention relates to a warp beam disc with a clamping ring which can be fastened to the outer surface of the disc by means of at least two axial fastening screws and can be tensioned by means of at least one clamping screw for releasably clamping the disc which can be screwed together with the clamping ring onto a warp beam tube.
- the invention further relates to a method for producing such a warp beam disc.
- Such a warp beam washer is screwed onto the externally threaded ends of a warp beam tube and must be secured against rotation at the desired axial distance from one another.
- This backup is usually done with a clamping ring that works independently of the Kettbaum disc, e.g. B. is provided with the internal thread required for screwing onto the warp beam tube in order to be connected to the warp beam disc after its processing.
- the clamping ring consists of a radially slotted clamping bracket, which is clamped in its circumference via a clamping screw guided approximately tangentially to the warp beam tube.
- This clamp is fastened to the Kettbaum washer using shaped fastening screws of Allen screws, the heads of which lie against the outer surface of the clamping bracket.
- the clamping ring consists of two clamping disks connected to one another via axial spacing webs, which are also completely machined separately from the Kettbaum washer and then fastened to the outer surface of the Kettbaum washer with fastening screws.
- a threaded fastener for fastening yarn limiting disks on a warp beam tube or the like by means of a locking nut is subdivided in a plane perpendicular to its axis into a fastening section and a clamping section, which are connected to one another via radially extending web-like connecting sections with a small circumferential width, but are otherwise separated from one another by a spacing slot.
- Tensioning openings for receiving tensioning bolts extend in partial sections that are aligned with one another through the fastening section and the tensioning section.
- the lock nut has a centering shoulder in the area of its fastening section for the assembly of the yarn limiting disk concentrically on the warp construction tube.
- This centering fit requires exact machining and is therefore particularly disadvantageous. Since the disc is only virtually floating on a very narrow ring collar formed by the centering projection, there is a great risk that the disc will be pressed out of the centering fit when subjected to high tilting moments. This danger is particularly great because the yarn limiting disk has no internal thread, that is, it is only pushed onto the warp beam tube with a clear radial distance. Another disadvantage is the need to slit the clamping ring on both sides with special tools except for the web-like connecting sections have to. Finally, the known embodiment is particularly long axially, since the clamping ring already requires a large axial length, which - apart from the length of the centering projection - adds to the axial length of the yarn limiting disk.
- the invention has for its object to simplify the warp beam described above, in particular with regard to their manufacture.
- the disc and the clamping ring have a continuous internal thread
- the clamping ring is supported directly on the outer surface of the disc via at least two supports arranged circumferentially offset, each forming a circular segment-shaped clamping gap, and that at least circumferentially offset in the region of the clamping gaps
- Two axial clamping screws are arranged in such a way that tightening the clamping screws in the clamping gap area reduces the clear axial distance between the clamping ring and the outer surface of the disk and thereby causes a flank pressure in the thread engagement.
- the above-mentioned object is achieved according to the invention in that the still unprocessed clamping ring is connected to the disc and then machined together with it, with an inner bore extending through the disc and clamping ring being produced in a single work step and then with a continuous internal thread is provided.
- the still unprocessed clamping ring can be connected to the warp beam disc and then processed together with it.
- the warp beam washer machined as a unit washer / clamping ring is then screwed onto the external thread of the associated warp beam tube and secured against rotation by tightening the clamping screws.
- each fastening screw is passed through a support, preferably three supports, each offset by 120 degrees of circumference, being provided.
- the supports can be designed in the form of ribs or can also be round. In the latter case, it is expedient if each fastening screw is passed through a support.
- the supports can in principle be provided on the back of the clamping ring. For manufacturing reasons, however, it appears easier to provide or cast the supports on the outer surface of the pane.
- the clamping ring lies within an annular groove in the outer pane surface and thus flush within this outer pane surface, and if all screw heads are sunk in the clamping ring.
- FIG. 1 shows a top view of a warp beam disc 1 to be screwed onto a warp beam tube (not shown in more detail), specifically its outer surface 1a.
- the disc 1 is cast and has in its outer surface 1a an annular groove 2 which serves to receive a clamping ring 3 shown in Figure 2.
- annular groove 2 which serves to receive a clamping ring 3 shown in Figure 2.
- three supports 4 each offset by 120 degrees of circumference, which in the exemplary embodiment shown are round, have a height of 2 to 4 mm and each enclose a pre-cast threaded hole 5 for receiving a fastening screw 6.
- a pre-cast threaded hole 7 for receiving a clamping screw 8 is provided in the middle between two supports 4.
- the clamping ring 3 inserted into the ring groove 2 rests on the three supports 4 and has a clear axial distance from the bottom of the ring groove 2 with its underside between the supports 4. This axial distance is referred to below as the clamping gap 9, which extends in the form of a segment of a circle between two supports 4.
- the clamping ring 3 is fastened in the annular groove 2 with the aid of the fastening screws 6, and is thereby pulled firmly against the supports 4. It is now possible to jointly machine the disc 1 connected to the clamping ring 3 in one setting. In this case, in particular in a single operation, the inner bore extending through the washer 1 and the clamping ring 3 and then an internal thread 10 are produced, with which the warp beam washer 1, together with the clamping ring 3 attached to it, on the external thread of an unspecified one Warp beam tube is screwed on.
- the three clamping screws 8 are screwed into the associated threaded holes 7 and tightened to such an extent that the clear axial distance between the clamping ring 3 and the outer disc surface 1 a is reduced in the clamping gap area and thereby a flank pressure in the thread engagement between the warp beam Washer 1 and warp beam tube is caused.
- Figure 2 shows that all screw heads 6a and 8a are arranged sunk in the clamping ring 3.
- FIG. 3 differs from that according to FIGS. 1 and 2 only in that the clamping ring 3 is not received in an annular groove but rests on the outer surface 1a of the bearing 4, which is somewhat superior.
- the separate processing of the clamping ring which would otherwise be necessary, is thus eliminated.
- the Kettbaum disc is ready for installation except for a surface treatment. This ensures exact concentricity.
- the processing costs are lower and therefore cheaper the entire product. Even existing embodiments can be converted to the system according to the invention with only low costs.
- the described exemplary embodiments enable the clamping ring to be exchanged due to the two-part design of the disc / clamping ring.
- the advantage of interchangeability of the clamping ring would no longer exist.

Description
Die Erfindung betrifft eine Kettbaum-Scheibe mit einem Klemmring, der über zumindest zwei axiale Befestigungsschrauben an der Scheibenaußenfläche befestigbar und über zumindest eine Klemmschraube spannbar ist zur lösbaren Klemmung der zusammen mit dem Klemmring auf ein Kettbaumrohr aufschraubbaren Scheibe. Die Erfindung betrifft ferner ein Verfahren zur Herstellung einer derartigen Kettbaum-Scheibe.The invention relates to a warp beam disc with a clamping ring which can be fastened to the outer surface of the disc by means of at least two axial fastening screws and can be tensioned by means of at least one clamping screw for releasably clamping the disc which can be screwed together with the clamping ring onto a warp beam tube. The invention further relates to a method for producing such a warp beam disc.
Jeweils eine derartige Kettbaum-Scheibe wird auf die mit einem Außengewinde versehenen Enden eines Kettbaumrohres aufgeschraubt und müssen in dem gewünschten axialen Abstand voneinander gegen ein Verdrehen gesichert werden. Diese Sicherung erfolgt üblicherweise mit einem Klemmring, der unabhängig von der Kettbaum-Scheibe bearbeitet, z. B. mit dem zum Aufschrauben auf das Kettbaumrohr erforderlichen Innengewinde versehen wird, um nach seiner Bearbeitung mit der Kettbaum-Scheibe verbunden zu werden.Such a warp beam washer is screwed onto the externally threaded ends of a warp beam tube and must be secured against rotation at the desired axial distance from one another. This backup is usually done with a clamping ring that works independently of the Kettbaum disc, e.g. B. is provided with the internal thread required for screwing onto the warp beam tube in order to be connected to the warp beam disc after its processing.
Bei einer vorbekannten Ausführungsform besteht der Klemmring aus einem radial geschlitzten Klemmbügel, der über eine angenähert tangential zum Kettbaumrohr geführte Klemmschraube in seinem Umfang verspannt wird. Die Befestigung dieses Klemmbügels mit der Kettbaum-Scheibe erfolgt über Befestigungsschrauben in Form von Inbusschrauben, deren Köpfe gegen die Außenfläche des Klemmbügels anliegen.In a known embodiment, the clamping ring consists of a radially slotted clamping bracket, which is clamped in its circumference via a clamping screw guided approximately tangentially to the warp beam tube. This clamp is fastened to the Kettbaum washer using shaped fastening screws of Allen screws, the heads of which lie against the outer surface of the clamping bracket.
Bei einer anderen vorbekannten Ausführungsform besteht der Klemmring aus zwei über axiale Abstandsstege miteinander verbundenen Klemmscheiben, die ebenfalls separat von der Kettbaum-Scheibe vollständig bearbeitet und dann mit Befestigungsschrauben an der Scheibenaußenfläche der Kettbaum-Scheibe befestigt werden. Durch Verspannen der beiden Klemmringhälften gegeneinander mit Hilfe von Klemmschrauben wird über eine Flankenpressung im Gewindeeingriff zwischen Klemmring und Kettbaumrohr ein Kraftschluß erzeugt.In another known embodiment, the clamping ring consists of two clamping disks connected to one another via axial spacing webs, which are also completely machined separately from the Kettbaum washer and then fastened to the outer surface of the Kettbaum washer with fastening screws. By tightening the two halves of the clamping ring against each other with the help of clamping screws, a positive connection is created via a flank pressure in the thread engagement between the clamping ring and the warp beam tube.
Die eingangs beschriebene Kettbaum-Scheibe läßt sich der EP 0 506 998 Al entnehmen. Offenbart ist ein Gewindeverschluß zur Befestigung von Garnbegrenzungsscheiben auf einem Kettbaumrohr oder dergleichen mittels einer Verschlußmutter. Letztere ist in einer Ebene senkrecht zu ihrer Achse in einen Befestigungsabschnitt und einen Spannabschnitt unterteilt, die über radial verlaufende stegartige Verbindungsabschnitte geringer Umfangsbreite miteinander verbunden, im übrigen aber durch einen Abstandsschlitz getrennt voneinander angeordnet sind. Spannöffnungen für die Aufnahme von Spannbolzen erstrecken sich in zueinander fluchtenden Teilabschnitten durch den Befestigungsabschnitt und den Spannabschnitt. Die Verschlußmutter weist im Bereich ihres Befestigungsabschnittes einen Zentrieransatz auf für die Montage der Garnbegrenzungsscheibe konzentrisch auf dem Kettbaurohr. Diese Zentrierpassung erfordert eine exakte Bearbeitung und ist daher besonders nachteilig. Da die Scheibe nur quasi fliegend auf einem sehr schmalen, durch den Zentrieransatz gebildeten Ringbund gelagert ist, besteht die große Gefahr, daß die Scheibe bei Beaufschlagung durch hohe Kippmomente aus der Zentrierpassung gedrückt wird. Diese Gefahr wird dadurch besonders groß, weil die Garnbegrenzungsscheibe kein Innengewinde aufweist, also mit einem lichten radialen Abstand auf das Kettbaumrohr lediglich aufgeschoben ist. Nachteilig ist weiterhin die Notwendigkeit, den Klemmring mit Spezialwerkzeugen beidseitig bis auf die stegartigen Verbindungsabschnitte schlitzen zu müssen. Schließlich baut die vorbekannte Ausführungsform axial besonders lang, da bereits der Klemmring eine große axiale Länge erfordert, die sich - bis auf die Länge des Zentrieransatzes-zu der Axiallänge der Garnbegrenzungsscheibe addiert.The Kettbaum disc described at the beginning can be found in EP 0 506 998 A1. Disclosed is a threaded fastener for fastening yarn limiting disks on a warp beam tube or the like by means of a locking nut. The latter is subdivided in a plane perpendicular to its axis into a fastening section and a clamping section, which are connected to one another via radially extending web-like connecting sections with a small circumferential width, but are otherwise separated from one another by a spacing slot. Tensioning openings for receiving tensioning bolts extend in partial sections that are aligned with one another through the fastening section and the tensioning section. The lock nut has a centering shoulder in the area of its fastening section for the assembly of the yarn limiting disk concentrically on the warp construction tube. This centering fit requires exact machining and is therefore particularly disadvantageous. Since the disc is only virtually floating on a very narrow ring collar formed by the centering projection, there is a great risk that the disc will be pressed out of the centering fit when subjected to high tilting moments. This danger is particularly great because the yarn limiting disk has no internal thread, that is, it is only pushed onto the warp beam tube with a clear radial distance. Another disadvantage is the need to slit the clamping ring on both sides with special tools except for the web-like connecting sections have to. Finally, the known embodiment is particularly long axially, since the clamping ring already requires a large axial length, which - apart from the length of the centering projection - adds to the axial length of the yarn limiting disk.
Der Erfindung liegt die Aufgabe zugrunde, die eingangs beschriebene Kettbaum-Scheibe inbesondere hinsichtlich ihrer Fertigung zu vereinfachen.The invention has for its object to simplify the warp beam described above, in particular with regard to their manufacture.
Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß Scheibe und Klemmring ein durchgehendes Innengewinde aufweisen, daß sich der Klemmring über zumindest zwei umfangsversetzt angeordnete, zwischen sich jeweils einen kreissegmentförmigen Klemmspalt bildende Auflager unmittelbar an der Scheibenaußenfläche abstützt, und daß umfangsversetzt im Bereich der Klemmspalte zumindest zwei axiale Klemmschrauben so angeordnet sind, daß ein Anziehen der Klemmschrauben im Klemmspaltbereich den lichten axialen Abstand zwischen Klemmring und Scheibenaußenfläche verringert und dadurch eine Flankenpressung im Gewindeeingriff hervorruft.This object is achieved according to the invention in that the disc and the clamping ring have a continuous internal thread, that the clamping ring is supported directly on the outer surface of the disc via at least two supports arranged circumferentially offset, each forming a circular segment-shaped clamping gap, and that at least circumferentially offset in the region of the clamping gaps Two axial clamping screws are arranged in such a way that tightening the clamping screws in the clamping gap area reduces the clear axial distance between the clamping ring and the outer surface of the disk and thereby causes a flank pressure in the thread engagement.
Hinsichtlich des Herstellungsverfahrens wird die vorstehend genannte Aufgabe gemäß der Erfindung dadurch gelöst, daß der noch unbearbeitete Klemmring mit der Scheibe verbunden und dann gemeinsam mit dieser bearbeitet wird, wobei in einem einzigen Arbeitsgang eine sich durch Scheibe und Klemmring erstreckende Innenbohrung hergestellt und diese anschließend mit einem durchgehenden Innengewinde versehen wird.With regard to the manufacturing process, the above-mentioned object is achieved according to the invention in that the still unprocessed clamping ring is connected to the disc and then machined together with it, with an inner bore extending through the disc and clamping ring being produced in a single work step and then with a continuous internal thread is provided.
Der wesentliche Vorteil gegenüber den vorbekannten Ausführungsformen ist darin zu sehen, daß der noch unbearbeitete Klemmring mit der Kettbaum-Scheibe verbunden und dann gemeinsam mit dieser bearbeitet werden kann. Die als Einheit Scheibe/Klemmring fertig bearbeitete Kettbaum-Scheibe wird dann auf das Außengewinde des zugeordneten Kettbaumrohres aufgeschraubt und hier durch Anziehen der Klemmschrauben gegen Verdrehung gesichert.The main advantage over the previously known embodiments can be seen in the fact that the still unprocessed clamping ring can be connected to the warp beam disc and then processed together with it. The warp beam washer machined as a unit washer / clamping ring is then screwed onto the external thread of the associated warp beam tube and secured against rotation by tightening the clamping screws.
Um über Flankenpressung eine exakte winklige Lage der Scheibe auf dem Kettbaumrohr zu erzielen, ist es zweckmäßig, wenn drei jeweils um 120 Umfangsgrad gegeneinander versetzte Klemmschrauben vorgesehen werden. Dabei ist es zweckmäßig, wenn jede Befestigungsschraube durch ein Auflager hindurchgeführt ist, wobei vorzugsweise drei jeweils um 120 Umfangsgrad gegeneinander versetzte Auflager vorgesehen sind.In order to obtain an exact angular position of the disc via side pressure To achieve on the warp beam tube, it is expedient if three clamping screws, each offset by 120 degrees of circumference, are provided. It is useful if each fastening screw is passed through a support, preferably three supports, each offset by 120 degrees of circumference, being provided.
Die Auflager können rippenförmig gestaltet oder aber auch rund ausgeführt sein. In letzterem Falle ist es dann zweckmäßig, wenn jede Befestigungsschraube durch ein Auflager hindurchgeführt ist. Dabei können die Auflager grundsätzlich auf der Rückseite des Klemmringes vorgesehen sein. Aus Herstellungsgründen erscheint es jedoch einfacher, die Auflager an der Scheibenaußenfläche vorzusehen bzw. anzugießen.The supports can be designed in the form of ribs or can also be round. In the latter case, it is expedient if each fastening screw is passed through a support. The supports can in principle be provided on the back of the clamping ring. For manufacturing reasons, however, it appears easier to provide or cast the supports on the outer surface of the pane.
Hinsichtlich einer Verringerung der Luftverwirbelung ist es vorteilhaft, wenn der Klemmring innerhalb einer Ringnut in der Scheibenaußenfläche und damit bündig innerhalb dieser Scheibenaußenfläche liegt, und wenn alle Schraubenköpfe im Klemmring versenkt angeordnet sind.With regard to a reduction in air turbulence, it is advantageous if the clamping ring lies within an annular groove in the outer pane surface and thus flush within this outer pane surface, and if all screw heads are sunk in the clamping ring.
Weitere Merkmale der Erfindung sind Gegenstand der Unteransprüche und werden in Verbindung mit weiteren Vorteilen der Erfindung anhand von Ausführungsbeispielen näher erläutert.Further features of the invention are the subject of the dependent claims and are explained in more detail in connection with further advantages of the invention on the basis of exemplary embodiments.

Figur 1 zeigt eine auf ein nicht näher dargestelltes Kettbaumrohr aufzuschraubende Kettbaum-Scheibe 1 und zwar deren Scheibenaußenfläche 1a in Draufsicht. Die Scheibe 1 ist gegossen und weist in ihrer Außenfläche 1a eine Ringnut 2 auf, die zur Aufnahme eines in Figur 2 dargestellten Klemmrings 3 dient. Im Boden der Ringnut 2 sind drei jeweils um 120 Umfangsgrad versetzt angeordnete Auflager 4 vorgesehen, die in dem dargestellten Ausführungsbeispiel rund ausgebildet sind, eine Höhe von 2 bis 4 mm aufweisen und jeweils ein vorgegossenes Gewindeloch 5 zur Aufnahme einer Befestigungsschraube 6 umschließen. Jeweils mittig zwischen zwei Auflagern 4 ist ein vorgegossenes Gewindeloch 7 zur Aufnahme einer Klemmschraube 8 vorgesehen.FIG. 1 shows a top view of a
Der in die Ringnut 2 eingelegte Klemmring 3 liegt auf den drei Auflagern 4 auf und weist mit seiner Unterseite zwischen den Auflagern 4 einen lichten axialen Abstand von dem Boden der Ringnut 2 auf. Dieser axiale Abstand wird nachfolgend als Klemmspalt 9 bezeichnet, der sich kreissegmentförmig jeweils zwischen zwei Auflagern 4 erstreckt.The
Der Klemmring 3 wird mit Hilfe der Befestigungsschrauben 6 in der Ringnut 2 befestigt, und dabei fest gegen die Auflager 4 gezogen. Es ist nunmehr möglich, die mit dem Klemmring 3 verbundene Scheibe 1 in einer Aufspannung gemeinsam zu bearbeiten. Hierbei werden insbesondere in einem einzigen Arbeitsgang die sich durch die Scheibe 1 und den Klemmring 3 erstreckende Innenbohrung und anschließend ein Innengewinde 10 hergestellt, mit dem dann später die Kettbaum-Scheibe 1 gemeinsam mit dem auf ihr befestigten Klemmring 3 auf das Außengewinde eines nicht näher dargestellten Kettbaumrohres aufgeschraubt wird. Zur axialen Fixierung der Kettbaum-Scheibe 1 auf dem Kettbaumrohr werden die drei Klemmschrauben 8 in die zugeordneten Gewindelöcher 7 eingeschraubt und soweit angezogen, daß sich im Klemmspaltbereich der lichte axiale Abstand zwischen Klemmring 3 und Scheibenaußenfläche 1a verringert und dadurch eine Flankenpressung im Gewindeeingriff zwischen Kettbaum-Scheibe 1 und Kettbaumrohr hervorgerufen wird.The
Figur 2 läßt erkennen, daß alle Schraubenköpfe 6a und 8a im Klemmring 3 versenkt angeordnet sind.Figure 2 shows that all
Die Ausführungsform gemäß Figur 3 unterscheidet sich von der gemäß den Figuren 1 und 2 lediglich darin, daß der Klemmring 3 nicht in einer Ringnut aufgenommen wird sondern auf die Scheibenaußenfläche 1a etwas überragenden Auflagern 4 aufliegt.The embodiment according to FIG. 3 differs from that according to FIGS. 1 and 2 only in that the
Bei der erfindungsgemäßen Kettbaum-Scheibe entfällt somit die sonst erforderliche getrennte Bearbeitung des Klemmringes. Nach der gemeinsamen Bearbeitung der Scheibe 1 mit ihrem Klemmring 3 ist die Kettbaum-Scheibe bis auf eine Oberflächenbehandlung einbaufertig. Hierdurch ist ein exakter Rundlauf gewährleistet. Die Bearbeitungskosten sind geringer und verbilligen somit das gesamte Produkt. Auch bereits vorhandene Ausführungsformen lassen sich auf das erfindungsgemäße System mit nur geringen Kosten umrüsten.In the Kettbaum washer according to the invention, the separate processing of the clamping ring, which would otherwise be necessary, is thus eliminated. After the joint processing of the
Die beschriebenen Ausführungsbeispiele ermöglichen jeweils einen Austausch des Klemmringes aufgrund der zweiteiligen Ausbildung Scheibe/Klemmring. Im Prinzip wäre es möglich, den Klemmring an die Scheibe anzugießen, im übrigen aber die beanspruchten Merkmale beizubehalten. Dadurch wäre natürlich auch eine einteilige Bearbeitung der Kombination Scheibe/Klemmring möglich, jedoch würde diese Lösung erheblich mehr Gußmaterial erfordern und somit zu einer Erhöhung der Scheibenmasse führen. Außerdem wäre nicht mehr der Vorteil der Austauschbarkeit des Klemmringes gegeben.The described exemplary embodiments enable the clamping ring to be exchanged due to the two-part design of the disc / clamping ring. In principle, it would be possible to cast the clamping ring onto the disk, but otherwise to retain the claimed features. This would of course also make it possible to machine the combination disc / clamping ring in one piece, but this solution would require considerably more casting material and thus lead to an increase in the disc mass. In addition, the advantage of interchangeability of the clamping ring would no longer exist.
