The technical problem is a locking which can absorb high torques. At that respective end of each screw-thread flight (15) located opposite the screw-in direction, there is provided a resilient tongue (17) with a detent lug (18) and in the screw-thread flight (12) paired therewith there is provided a window (13) into which the detent lug (18) engages. <IMAGE>

Description

Die Erfindung betrifft eine Spule aus einem Kernrohr und zwei Scheiben jeweils mit einem axialen Stutzen, wobei jeweils ein Stutzen und ein Ende des Kernrohrs mit Gewinden und mit paarig zueinander ausgebildeten Rastelementen formschlüssig ineinandergreifen.The invention relates to a coil made of a core tube and two disks, each with an axial connecting piece, wherein one connecting piece and one end of the core tube engage in a form-fitting manner with threads and with locking elements formed in pairs with one another.

Eine Spule dieser Gattung ist in der DE-C2-3 902 108 beschrieben. Die Rastelemente sind in der Stirnfläche des Kernrohres ausgebildet und greifen in die Zentralfläche der jeweiligen Scheibe ein. Dadurch ist die Momentenaufnahme begrenzt, so daß Schädigungen durch hohe Belastungen möglich sind.A coil of this type is described in DE-C2-3 902 108. The locking elements are formed in the end face of the core tube and engage in the central surface of the respective disk. As a result, the moment absorption is limited, so that damage from high loads is possible.

Aufgabe der Erfindung ist eine Verrastung, die hohe Momente aufnehmen kann.The object of the invention is a latching that can absorb high moments.

Diese Aufgabe wird nach der Erfindung dadurch gelöst, daß jeweils an dem entgegen der Einschraubrichtung gelegenen Ende jedes Gewindegangs eine nachgiebige Zunge mit einer Rastnase und in dem dazu paarigen Gewindegang ein Fenster vorgesehen ist, in das die Rastnase eingreift.This object is achieved according to the invention in that a resilient tongue with a locking lug is provided at the opposite end of the thread of each thread and in the paired thread there is a window into which the locking lug engages.

Die Erfindung unterscheidet sich insofern vom Stand der Technik, als die in den Umfangsflächen des Kernrohrs und der Stutzen ausgebildeten Rastelemente groß bemessen werden können. Infolgedessen können auch große Kräfte uind Momente ohne übermäßige Belastung aufgenommen werden.The invention differs from the prior art in that the locking elements formed in the peripheral surfaces of the core tube and the connecting piece can be dimensioned large. As a result, large forces and moments can be absorbed without excessive stress.

Besonders stabile Verhältnisse ergeben sich durch eine derartige Zuordnung der Rastelemente, daß die Zunge in dem jeweiligen Schraubengewindegang durch einen U-förmigen Ausschnitt begrenzt ist und daß das Fenster in dem Muttergewindegang vorgesehen ist.Particularly stable conditions result from such an assignment of the locking elements that the tongue in the respective screw thread is delimited by a U-shaped cutout and that the window is provided in the nut thread.

Eine Mehrzahl von Verrastungen erzielt man dadurch, daß jedes Ende des Kernrohrs ein doppelgängiges Schraubengewinde und jeder Stutzen einer Scheibe ein doppelgängiges Muttergewinde aufweist.A plurality of catches are achieved in that each end of the core tube has a double-start screw thread and each socket of a disc has a double-start nut thread.

Ein ungebremstes Abrollen der Spulen verhindert man dadurch, daß jede Scheibe eine Aufnahmehülse mit in Umfangsrichtung ausgerichteten Innennocken und ein in die Aufnahmehülse eingreifender Tragzapfen Traglamellen aufweist.An unbraked rolling of the coils is prevented in that each disk has a receiving sleeve with inner cams aligned in the circumferential direction and a supporting pin which engages in the receiving sleeve.

Im Einzelnen ist vorgesehen, daß mehrere radial ausgerichtete Traglamellen sternförmig angeordnet sind.In detail, it is provided that a plurality of radially aligned support lamellae are arranged in a star shape.

Eine Weiterbildung sieht vor, daß die Innenwand der Aufnahmehülse Bremsrippen als Innennocken aufweist.A further development provides that the inner wall of the receiving sleeve has brake ribs as inner cams.

Ein Ausführungsbeispiel der Erfindung wird unter Bezugnahme auf die Zeichnung erläutert, in der darstellen:

  • Fig. 1 eine aufgebrochene Ansicht einer Spule mit Scheiben,
  • Fig. 2 ein Ende des Kernrohrs in vergrößertem Maßstab,
  • Fig. 3 eine Stirnansicht des Kernrohrs,
  • Fig. 4 eine Einzelansicht eines Tragzapfens,
  • Fig. 5 eine Stirnansicht zu Fig. 4 und
  • Fig. 6 eine entgegengesetzte Stirnansicht wie in Fig. 5.
An embodiment of the invention is explained with reference to the drawing, in which:
  • 1 is a broken away view of a coil with disks,
  • 2 an end of the core tube on an enlarged scale,
  • 3 is an end view of the core tube,
  • 4 shows a single view of a trunnion,
  • Fig. 5 is an end view of Fig. 4 and
  • 6 is an opposite end view as in Fig. 5th

Eine Spule mit Scheiben, auch als Scheibenspule oder als Flanschspule bezeichnet, umfaßt zwei durch ein in Fig. 1 nur schematisch dargestelltes Kernrohr 1 miteinander verbundene Scheiben 2, die jeweils einen axialen Stutzen 3 aufweisen, in den jeweils ein radial nach innen abgesetzter Endabschnitt 4 des Kernrohrs 1 eingreift.A coil with disks, also referred to as a disk coil or as a flange coil, comprises two disks 2 which are connected to one another by a core tube 1 which is only shown schematically in FIG Core tube 1 engages.

Jede Scheibe 2 hat konzentrisch zu dem Stutzen 3 eine Aufnahmehülse 4, in deren Innendurchgang 5 ein Tragzapfen 6 einsteckbar ist. Auf der Innenwand des Innendurchgangs 5 sind axial ausgerichtete Bremsrippen 7 angeordnet.Each disc 2 has a receptacle 4 concentric with the nozzle 3, in the inner passage 5 of which a support pin 6 can be inserted. Axially aligned brake ribs 7 are arranged on the inner wall of the inner passage 5.

Jeder Stutzen 3 hat in der Innenwand zwei Muttergewindegänge 12 in Form eines doppelgängigen Gewindes. Jeder Muttergewindegang 12 hat im Endbereich ein Fenster 13 für eine Verrastung, in der Ringwand 14 der Scheibe sind ebenfalls nicht dargestellte Rastfenster ausgebildet.Each nozzle 3 has two female threads 12 in the form of a double thread in the inner wall. Each nut thread 12 has a window 13 for latching in the end region, latching windows (not shown) are also formed in the annular wall 14 of the disk.

Der zugehörige Endabschnitt 11 des Kernrohrs trägt zwei Schraubengewindegänge 15, die ein doppelgängiges Schraubengewinde bilden. In Endbereich jedes Schraubengewindesgangs 15 trennt ein U-förmiger Ausschnitt 16 eine Zunge 17 frei, so daß diese Zunge 17 in radialer Richtung nachgiebig ist. An der Zunge 17 sitzt eine Rastnase 18, die in das zugehörige Fenster 13 paßt.The associated end section 11 of the core tube carries two screw threads 15, which form a double-start screw thread. In the end region of each screw thread 15, a U-shaped cutout 16 separates a tongue 17 so that this tongue 17 is flexible in the radial direction. On the tongue 17 there is a latch 18 which fits into the associated window 13.

Am Stirnende des Endabschnitts 11 sind in axialer Richtung bewegliche Nasen 19 freigeschnitten, die in die nicht dargestellten Rastfenster der Ringwand 14 eingreifen.At the front end of the end portion 11 movable noses 19 are cut free, which engage in the not shown locking window of the ring wall 14.

Das Kernrohr 1 und die Scheiben 2 werden durch Ineinanderschrauben zur vollständigen Spule zusammengesetzt. Beim Einschrauben greifen die Rastverbindungen ineinander und halten die Teile zusammen. Die Rastzungen der Gewindegänge können große Momente aufnehmen, weil sie großflächig ausgebildet sind. Damit erhält man eine sehr stabile Spule, die für schwere Bewicklungen geeignet ist.The core tube 1 and the disks 2 are assembled by screwing into one another to form the complete coil. When screwing in, the snap connections engage and hold the parts together. The locking tongues of the threads can take up large moments because they are formed over a large area. This gives you a very stable spool that is suitable for heavy windings.

An einem Ringstutzen 21 des Tragzapfens 6 ist über mehrere radiale Stege 22 eine Ringwand 23 gehalten, die somit in radialer Richtung und in Umfangsrichtung nachgiebig ist. Auf der Außenfläche der Ringwand 23 befinden sich Traglamellen 8, die sternförmig angeordnet sind. Die Traglamellen 8 wirken mit den Bremsrippen 7 der Aufnahmehülse 4 zusammen, Die Anzahl der Bremsrippen 7 kann mit der Anzahl der Traglamellen übereinstimmen oder davon verschieden sein.An annular wall 23 is held on an annular connecting piece 21 of the trunnion 6 via a plurality of radial webs 22 and is therefore flexible in the radial direction and in the circumferential direction. On the outer surface of the ring wall 23 there are support lamellae 8 which are arranged in a star shape. The support plates 8 interact with the brake ribs 7 of the receiving sleeve 4. The number of brake ribs 7 can correspond to the number of support plates or be different therefrom.

In entgegengesetzter axialer Richtung sitzt an dem Tragzapfen 6 ein Profilbund 9 z.B. ein Quadratbund, der in einen Halter zur Aufnahme der Scheibenspule einsetzbar ist. Der Halter nimmt den Profilbund 9 z.B. in einem Schlitz auf. Der Halter befindet sich an einem Gestell.In the opposite axial direction, a profile collar 9, e.g. a square collar that can be inserted into a holder for receiving the disc spool. The holder takes the profile collar 9 e.g. in a slit. The holder is on a frame.

Zwei Tragzapfen 6 werden von gegenüberliegenden Seiten in die Aufnahmehülsen 4 der Scheiben 2 eingesetzt. Dabei legen sich die Bremsrippen 7 an den Traglamellen 8 an. Die Tragzapfen 6 werden in Schlitze einer entsprechenden Aufnahme eingeführt. Die Scheibenspule ist damit gehalten und gegen ein unbeabsichtigtes Abrollen gesichert. Das auf der Scheibenspule aufgewickelte bandförmige Material kann abgezogen werden. Dabei erfolgt beim Gleiten der Bremsrippen über die Traglamellen eine Abbremsung. Es wird also nie zuviel oder unbeabsichtigt Material abgerollt.Two support pins 6 are inserted into the receiving sleeves 4 of the disks 2 from opposite sides. The brake ribs 7 put on the support plates 8. The trunnions 6 are inserted into slots of a corresponding receptacle. The disc spool is thus held and secured against unintentional rolling off. The band-shaped material wound on the disc spool can be pulled off. Braking takes place when the brake ribs slide over the supporting plates. So too much or unintentional material is never unrolled.
