Description

Die Erfindung betrifft eine Vorrichtung zur Führung eines aus einzelnen Segmenten bestehenden Wanderdeckels einer Karde oder Krempels gemäss Oberbegriff des unabhängigen Anspruches.The invention relates to a device for guiding a revolving cover consisting of individual segments of a card or card according to the preamble of the independent claim.

Die Entwicklung der Karde in den letzten 30 Jahren ging primär dahin, die Karde derart zu verändern, um Leistungssteigerungen im Durchsatz der Karde im Rahmen eines Vielfachen zu ermöglichen.The development of the card over the past 30 years has primarily been to change the card in such a way as to enable performance increases in throughput of the card in a multiple.

Es ist an sich bekannt, dass eine Karde nebst Einspeisung, Briseur und Abnehmer im wesentlichen einen sich drehenden Tambour mit einer darauf befestigten Spitzengarnitur und einen mindestens teilweise um den Umfang des Tambours herumgeführten Deckel, und zwar in der Regel einen sogenannten Wanderdeckel, umfasst.It is known per se that, in addition to the infeed, the breeze and the customer, a card essentially comprises a rotating drum with a tip assembly fastened thereon and a cover, at least partially guided around the circumference of the drum, as a rule a so-called revolving cover.

Ein solcher Deckel ist ebenfalls mit einer Spitzengarnitur versehen, so dass die zwischen den Spitzen des Tambours und des Deckels befindlichen Faserflocken verstreckt, das heisst zu einem dünnen Faserflor auseinandergezogen werden, in welchem ebenfalls mit Hilfe der genannten Spitzen die Fasern parallelisiert werden, so dass am Ausgang der Karde das sogenannte Faservlies mit im wesentlichen parallelisierte Fasern entsteht, welches letztlich zu einem Kardenband zusammengefasst wird.Such a lid is also provided with a lace set, so that the fiber flakes located between the tips of the drum and the lid are stretched, that is to say pulled apart to form a thin fiber web, in which the fibers are also parallelized with the aid of the tips mentioned, so that on At the end of the card, the so-called fiber fleece with essentially parallel fibers is created, which is ultimately combined into a card sliver.

Es ist ebenfalls bekannt, dass der Abstand zwischen den Spitzen der Deckelgarnitur und den Spitzen der Tambourgarnitur eine wesentliche Rolle spielt, um ein gutes Kardierresultat zu erhalten, so dass es naheliegt zu verstehen, dass dieser Abstand möglichst genau eingehalten werden muss, wie gross dieser auch immer ist. Dabei ist bezüglich Abstand ebenfalls bekannt, dass es sich beim Abstand dieser genannten Spitzen um wenige Zehntelsmillimeter handelt, so dass es wiederum verständlich ist, dass es nicht völlig problemlos ist, in einer Maschine mit der Grösse und dem Gewicht einer Karde die Führung des Tambours und der Deckel so zu gestalten, dass einerseits ein möglichst kleiner Abstand zwischen den Spitzen möglich ist und, dass andererseits dieser Abstand auch möglichst genau eingehalten werden kann um zu vermeiden, dass gelegentlich die Spitzen sich berühren.It is also known that the distance between the tips of the cover set and the tips of the drum set plays an essential role in order to obtain a good carding result, so it is obvious to understand that this distance must be kept as accurate as possible, such as big this is always. With regard to the distance, it is also known that the distance between these points mentioned is a few tenths of a millimeter, so that it is understandable that it is not entirely problem-free to guide the drum and in a machine with the size and weight of a card to design the lid so that on the one hand the smallest possible distance between the tips is possible and that on the other hand this distance can also be kept as precisely as possible to avoid that the tips occasionally touch each other.

Dabei ist das sich Berühren der Spitzen auch nur das eine Problem, das andere Problem liegt in der Technologie, nämlich, dass das technologische Kardier-Resultat beim Verändern des Abstandes um nur einen Zehntelsmillimeter völlig verschieden sein kann.Touching the tips is only one problem, the other problem lies in the technology, namely that the technological carding result can be completely different by changing the distance by just a tenth of a millimeter.

Die Anmelderin hat deshalb bereits im veröffentlichten Europa-Patent Nr. 0 015 974 eine Erfindung geschützt, in welcher die Wärmeausdehnung der einzelnen Teile berücksichtigt wird, um entsprechende Veränderungen an Einstellungen vorzunehmen, welche den Abstand zwischen den genannten Spitzen bei unterschiedlichen Temperaturen gewährleisten sollen.The applicant has therefore already protected an invention in published European Patent No. 0 015 974, in which the thermal expansion of the individual parts is taken into account in order to make corresponding changes to settings which are intended to ensure the distance between the said tips at different temperatures.

In der Regel sind die Wanderdeckelsegmente beidseits des Tambours auf einer Führungsfläche der sogenannten Tambourschildern (auch Kardenwände genannt) geführt, wobei zwischen den Flächen der Deckelsegmente und der genannten Führungsfläche Gleitreibung herrscht.As a rule, the revolving cover segments are guided on both sides of the reel on a guide surface of the so-called reel plates (also called card walls), with sliding friction prevailing between the surfaces of the cover segments and the mentioned guide surface.

Dementsprechend besteht das weitere Problem der Schmierung indem entweder die aufeinandergleitenden Materialien derart gewählt werden müssen, dass eine Gleitreibung ohne Schmierstoffe möglich ist oder es müssen Schmierstoffe von einer Art gewählt werden, welche bei nur sehr kleinem Auftrag gute Gleiteigenschaften gewährleisten. Anderseits sollen solche Schmiermittel in keiner Weise mit der Baumwolle in Berührung kommen, um ein Verschmutzen der Fasern zu vermeiden.Accordingly, there is the further problem of lubrication in that either the materials sliding on one another must be selected in such a way that sliding friction is possible without lubricants, or lubricants of a type which are good with only a very small order must be selected Ensure sliding properties. On the other hand, such lubricants should in no way come into contact with the cotton in order to avoid soiling of the fibers.

Wenn sich auch, wie vorerwähnt, die wesentliche Entwicklung der Karde in den letzten dreissig Jahren auf die Durchsatzleistung bezog, so wurde das Problem der Führung der Wanderdeckel und deren Schmierung bereits früh erkannt, indem bereits im Jahre 1929 ein Franzose eine Erfindung in der englischen Patentanmeldung mit der Veröffentlichungsnummer 304 780 veröffentlichte, in welcher die Möglichkeit geschaffen wurde, die Segmente der Wanderdeckel ohne Gleitreibung zu führen, indem beidseits der Karde Tragscheiben frei drehend auf der Tambourwelle vorgesehen wurden, auf welchen die Segmente der Wanderdeckel auflagen, um so gleitreibungsfrei geführt zu werden.Even though, as mentioned above, the essential development of the card in the last thirty years was related to the throughput, the problem of guiding the revolving cover and its lubrication was recognized early on, as early as 1929 a Frenchman invented the English patent application with the publication number 304 780, in which the possibility was created to guide the segments of the revolving cover without sliding friction, by providing support disks on both sides of the card, on which the segments of the revolving cover rested, so that they could be guided without sliding friction .

Um den Abstand zwischen den Spitzen verändern zu können, wurden die Tragscheiben mit verstellbaren Segmenten versehen, so dass der Radius der Tragoberfläche der Tragscheiben verändert werden konnte.In order to be able to change the distance between the tips, the support disks were provided with adjustable segments, so that the radius of the support surface of the support disks could be changed.

Das Problem lag jedoch darin, das einerseits das Verstellen dieser Segmente nur mit zusätzlichen Hilfsmitteln durchgeführt werden konnte, da die genannten Segmente lediglich mit Hilfe von Schrauben an das Grundelement der Tragscheiben befestigt waren.The problem, however, was that on the one hand, the adjustment of these segments could only be carried out with additional aids, since the segments mentioned were only attached to the base element of the support disks with the aid of screws.

Es bestand demnach zwar die Möglichkeit, den genannten Abstand zwischen Spitzen anzupassen, die Art und Weise jedoch um dies durchzuführen war äusserst problematisch und insofern schwierig, als dass nur schwerlich Veränderungen in Zehntelsmillimetern durchgeführt werden konnten.It was therefore possible to adjust the distance between the tips mentioned, but the way to do this was extremely problematic and difficult in that it was difficult to make changes in tenths of a millimeter.

Es bestand deshalb die Aufgabe, die Wanderdeckel derart zu führen, dass Schmierprobleme beseitigt und die Führung derart gestaltet werden konnte, dass das Verstellen der Abstände zwischen den Garniturspitzen genau und relativ mühelos durchgeführt werden konnte.The task was therefore to guide the revolving cover in such a way that lubrication problems were eliminated and the guide could be designed in such a way that the spacing between the clothing tips could be adjusted precisely and relatively effortlessly.

Die Aufgabe wurde durch die im Kennzeichen des ersten Anspruches aufgeführten Merkmale gelöst.The object was achieved by the features listed in the characterizing part of the first claim.

Weitere vorteilhafte Ausführungsformen sind in den weiteren abhängigen Ansprüchen aufgeführt.Further advantageous embodiments are listed in the further dependent claims.

Die Erfindung wird im weiteren mit Hilfe der begleitenden Zeichnungen beispielsweise beschrieben.The invention is further described, for example, with the aid of the accompanying drawings.

Figur 1 zeigt einen Teil einer Karde 1 mit einem Tambour 2, welcher mittels einer Welle 3 im stationären Tambourschild 4 (auch Kardenwand genannt) mittels Wälzlager 5 drehbar- und antreibbar (nicht dargestellt) ist.FIG. 1 shows part of a card 1 with a reel 2, which by means of a shaft 3 in the stationary reel plate 4 (also called card wall) can be rotated and driven by means of roller bearings 5 (not shown).

Auf dem Tambour ist mit 6 eine Kardengarnitur gekennzeichnet.A card set is marked with 6 on the reel.

Auf einem Wellenstummel 29 (auch Wellenfortsatz genannt) ist ein Scheibenrad 26 frei drehend gelagert. Das Scheibenrad 26 umfasst eine Tragscheibe 17, welche auf einem Konus 16 eines Klemmringes 14 getragen wird.On a stub shaft 29 (also called a shaft extension), a disc wheel 26 is freely rotating. The disk wheel 26 comprises a support disk 17 which is carried on a cone 16 of a clamping ring 14.

Der Klemmring selbst ist verschiebbar auf einer Traghülse 10 gelagert, welche ihrerseits über zwei als spielfreie Lager kombinierte Wälzlager 8 und 9 auf dem Wellenstummel 29 drehbar gelagert ist.The clamping ring itself is slidably mounted on a support sleeve 10, which in turn is rotatably mounted on the shaft end 29 via two roller bearings 8 and 9 combined as play-free bearings.

Um einen Abstand zwischen dem Wälzlager 5 der Tambourwelle 3 und dem Wälzlager 8 der Traghülse 10 zu erhalten, ist zwischen diesen beiden Wälzlagern ein Distanzring 7 vorgesehen.In order to maintain a distance between the roller bearing 5 of the drum shaft 3 and the roller bearing 8 of the support sleeve 10, a spacer ring 7 is provided between these two roller bearings.

Um den Klemmring 14 auf der Traghülse 10 festzuklemmen, weist einerseits dieser Klemmring 14 einen durchgehenden Schlitz 25 (s. Figur 2) auf, sowie eine Klemm-Mutter 15, welche auf einem Gewinde 48 gegen den Fuss der Tragscheibe 17 bewegt werden kann, so dass der Fuss der Tragscheibe 17 auf dem Konus 16 nach rechts, mit Blickrichtung auf Figur 1 gesehen, verschoben wird und dadurch der geschlitzte Klemmring 14 auf der Traghülse 10 festgeklemmt wird. Der Konus darf dabei nicht selbsthemmend vorgesehen werden.In order to clamp the clamping ring 14 on the support sleeve 10, on the one hand this clamping ring 14 has a continuous slot 25 (see FIG. 2), and a clamping nut 15, which can be moved on a thread 48 against the foot of the support disk 17, so that the base of the support disk 17 on the cone 16 is shifted to the right, as viewed in the direction of FIG. 1, and the slotted clamping ring 14 is thereby clamped on the support sleeve 10. The cone must not be self-locking.

Um ein Mass für das Verschieben des Klemmringes 14 auf der Traghülse 10 zu erhalten, sind auf der Traghülse 10 Teilstriche ab 11 angebracht.In order to obtain a measure for the displacement of the clamping ring 14 on the support sleeve 10, 10 graduation marks from 11 are attached to the support sleeve.

Das Verschieben des Klemmringes 14 auf der Traghülse 10 kann in der vom Kardenschild 4 weggerichteten Richtung mittels einer Anschlagschraube 36 geschehen, welche in einer Gewindebohrung 37 im Kardenschild 4 drehbar ist. Dabei ist, um zu dieser Schraube 36 zu gelangen, in der Tragscheibe 17 eine Öffnung 38 vorgesehen. In der entgegengesetzten Richtung wird die Traghülse von Hand bis zum Anschlag an der Anschlagschraube 36 verschoben.The displacement of the clamping ring 14 on the support sleeve 10 can by means of in the direction away from the card plate 4 happen a stop screw 36 which is rotatable in a threaded bore 37 in the card plate 4. In order to arrive at this screw 36, an opening 38 is provided in the support disk 17. In the opposite direction, the support sleeve is pushed by hand until it stops on the stop screw 36.

Mittels einer auf einem zum Wellenstummel 29 gehörenden Gewindestummel 13 aufgesetzten Befestigungsmutter 12 werden die Gleitlager 8 und 9 gegen den Distanzring 7 gepresst und damit festgeklemmt.The slide bearings 8 and 9 are pressed against the spacer ring 7 and thus clamped by means of a fastening nut 12 placed on a threaded stub 13 belonging to the shaft stub 29.

Die Tragscheibe 17 weist an ihrem äusseren Umfange ebenfalls einen Konus auf, welcher einer Konusfläche 20 eines Deckelsegmentes 27 entspricht.The support disk 17 also has a cone on its outer circumference, which corresponds to a conical surface 20 of a cover segment 27.

Alle Deckelsegmente 27 zusammen ergeben einen Wanderdeckel 19, welcher in Figur 2 schematisch dargestellt ist. Daraus ist ersichtlich, dass im Arbeitsbereich AB (mit strichpunktierter Linie angedeutet) des Wanderdeckels, in welchem dessen Garnituren den Garnituren des Tambours 2 gegenüberliegen, die Wanderdeckelsegmente 27 einerseits auf der Tragscheibe 17 aufliegen und andererseits mit einer Führungsfläche 35 am Kardenschild 4 anliegen und dadurch in axialer Richtung des Tambours 2 geführt sind, während im Ruhebereich, das heisst im oberen Bereich des Wanderdeckels, mit Blick auf Figur 2 gesehen, die Deckelsegmente 27 auf den Deckelrädern 21 aufliegen. Die Führung der Deckelsegmente 27 auf den Deckelrädern 21 geschieht, indem eine zu jedem Deckelsegment gehörende Führungszunge 22 in eine Führungsnute 23 jedes Deckelrades 21 greift.All cover segments 27 together result in a revolving cover 19, which is shown schematically in FIG. 2. From this it can be seen that in the working area AB (indicated by a dash-dotted line) of the revolving cover, in which its trimmings lie opposite the trimmings of the spool 2, the revolving cover segments 27 lie on the one hand on the support disk 17 and on the other hand rest with a guide surface 35 on the card plate 4 and thereby in are guided in the axial direction of the drum 2, while in the rest area, that is to say in the upper area of the revolving cover, with a view of FIG. 2, the cover segments 27 rest on the cover wheels 21. The cover segments 27 are guided on the cover wheels 21 by a guide tongue 22 belonging to each cover segment engaging in a guide groove 23 of each cover wheel 21.

Aus Figur 2 ist im weiteren noch ersichtlich, dass die Klemm-Mutter 15 mit zwei zueinander parallelen Flächen 28 versehen ist, so dass mittels eines dazu passenden Werkzeuges (beispielsweise eines Gabelschlüssels) die Klemm-Mutter 15 gegen den Fuss 33 der Tragscheibe 17 gedreht werden kann.It can also be seen from FIG. 2 that the clamping nut 15 is provided with two mutually parallel surfaces 28, so that by means of a suitable tool (For example, a wrench) the clamping nut 15 can be rotated against the foot 33 of the support plate 17.

Um ein gleichmässiges Anpressen des Fusses 33 der Tragscheibe 17 auf dem Konus 16 des Klemmringes 14 zu erreichen, kann ein an den Flächen 28 der Klemm-Mutter 15 angesetztes Werkzeug mit einer Drehmomentanzeige versehen sein, so dass immer mit demselben Drehmoment die Klemm-Mutter 15 angezogen werden kann, um eine gleichbleibende, vorgegebene Lage des Fusses 33 auf dem Konus 16 zu gewährleisten.In order to achieve a uniform pressing of the foot 33 of the support disk 17 on the cone 16 of the clamping ring 14, a tool attached to the surfaces 28 of the clamping nut 15 can be provided with a torque indicator, so that the clamping nut 15 always has the same torque can be tightened to ensure a constant, predetermined position of the foot 33 on the cone 16.

Es versteht sich, dass die Konusfläche 20 der Deckelsegmente 27 in rein darstellerischer Weise übertrieben stark konisch gewählt wurde und dass in der Praxis es sich bei diesem Konus um einen Konus von sehr kleinem Öffnungswinkel α handelt, und zwar derart, dass beim Verschieben der Tragscheibe 17 nie mehr als der Abstand zwischen den Garnituren 6 und 24 und einer durch Schleifen verursachten Verkürzung der Garnitur 6 kompensiert wird. Dabei wird der Öffnungswinkel α durch die imaginare Fortsetzung der Konusfläche 20 und durch eine Parallele zur Tambourwelle 3 gebildet.It goes without saying that the conical surface 20 of the cover segments 27 was chosen to be exaggeratedly strongly conical in a purely illustrative manner and that in practice this cone is a cone with a very small opening angle α, in such a way that when the support disk 17 is moved never more than the distance between the sets 6 and 24 and a shortening of the set 6 caused by grinding is compensated. The opening angle α is formed by the imaginary continuation of the conical surface 20 and by a parallel to the drum shaft 3.

Aus Figur 2 ist im weiteren ersichtlich, dass die Deckelräder 21 an beiden Enden des Arbeitsbereiches AB mittels in stationären Wellenlagern 72 und 73 gelagerten Deckelwellen 70 und 71 stationär jedoch drehbar sind, und dass die mittleren Deckelräder 21 mittels einer in einem verschiebbaren Wellenlager 75 gelagerten und angetriebenen Deckelwelle 74 für das Spannen des Wanderdeckels verschiebbar sind. Dabei umfasst das dazu pro mittleres Deckelrad 21 notwendige Spannmittel 76 je eine das Wellenlager 75 aufnehmende Spannschraube 77, welche in einem stationären, mit entsprechendem Gewinde versehenen Schraubenlager drehbar gelagert ist.From FIG. 2 it can further be seen that the cover wheels 21 can be rotated in a stationary manner at both ends of the working area AB by means of cover shafts 70 and 71 mounted in stationary shaft bearings 72 and 73, and that the center cover wheels 21 are mounted in a displaceable shaft bearing 75 and driven cover shaft 74 are displaceable for tensioning the revolving cover. The clamping means 76 required for each central cover wheel 21 each include a clamping screw 77 receiving the shaft bearing 75, which is rotatably mounted in a stationary screw bearing provided with a corresponding thread.

Die Figuren 3 und 4 zeigen insofern eine Variante der Vorrichtung der Figuren 1 und 2 als zwei koaxiale Scheibenräder pro Tambourstirnseite vorgesehen sind, nämlich ein Scheibenrad 26.1 und Scheibenrad 26.2. Dabei ist der Aufbau dieser beiden Scheibenräder gleich wie der Aufbau des Scheibenrades 26, weshalb gewisse Bezugszeichen lediglich mit einer Zusatzzahl, beispielsweise einer 1 für die Teile des Scheibenrades 26.1 und einer 2 für die Teile des Scheibenrades 26.2 versehen sind.FIGS. 3 and 4 show a variant of the device of FIGS. 1 and 2 in that two coaxial disk wheels are provided per drum face, namely a disk wheel 26.1 and disk wheel 26.2. The structure of these two disc wheels is the same as the structure of the disc wheel 26, which is why certain reference numerals are only provided with an additional number, for example a 1 for the parts of the disc wheel 26.1 and a 2 for the parts of the disc wheel 26.2.

Die Wanderdeckel 19.1 und 19.2 sind in Figur 3 der Einfachheit halber auf gleicher Ebene gezeigt, währenddem sie in Wirklichkeit wie mit Figur 4 gezeigt nebeneinander, mit Blick auf Figur 4 gesehen, um den Tambour 2 angeordnet sind.The revolving lids 19.1 and 19.2 are shown in FIG. 3 for the sake of simplicity on the same level, whereas in reality they are arranged next to one another around the drum 2, as seen in FIG.

In Figur 2 wie auch in Figur 4 ist der Tambourschild 4 lediglich schematisch angedeutet.In Figure 2 as well as in Figure 4, the drum shield 4 is only indicated schematically.

Der Wellenstummel 29.2 mit dem Gewindestummel 13.2, auf welchem das Scheibenrad 26.2 freidrehend befestigt ist, ist mittels eines zum Wellenstummel 29.2 gehörenden Gewindebolzens 32 in einem Innengewinde 31 des Wellenstummels 29.1 eingelassen und fest angezogen, so dass der Wellenstummel 29.2 fest mit dem Wellenstummel 29.1 verbunden ist.The shaft stub 29.2 with the threaded stub 13.2, on which the disk wheel 26.2 is fastened in a freely rotating manner, is inserted and tightened in an internal thread 31 of the shaft stub 29.1 by means of a threaded bolt 32 belonging to the shaft stub 29.2, so that the shaft stub 29.2 is firmly connected to the shaft stub 29.1 .

Als Anschlag für den Distanzring 7.2 des Scheibenrades 26.2 ist am Wellenstummel 29.2 ein Anschlag 30 vorgesehen. Effektiv liegt der Wellenstummel 29.2 mittels dieses Anschlages 30 an der Stirnseite des Wellenstummels 29.1 an.A stop 30 is provided on the shaft end 29.2 as a stop for the spacer ring 7.2 of the disk wheel 26.2. The shaft stub 29.2 effectively lies against the end face of the shaft stub 29.1 by means of this stop 30.

Die Führungsfläche 35.2 liegt an einem parallel zum Kardenschild 4 stationär angeordneten Führungsbogen 39 (Fig. 3, in Fig. 4 mit strichpunktierter Linie angeordnet) an, welcher sich über den Arbeitsbereich AB.2 (Fig. 4) erstreckt.The guide surface 35.2 bears against a guide bend 39 (FIG. 3, arranged with a dash-dotted line in FIG. 4), which is arranged parallel to the card plate 4 and extends over the working area AB.2 (FIG. 4).

In den Figuren 3 und 4 wird die Karde mit 1.1 gekennzeichnet.In Figures 3 and 4, the card is marked 1.1.

Die Figur 5 zeigt mit einem Scheibenrad 26.3 eine Variante des Scheibenrades 26 von Figur 1, indem eine mit 40 bezeichnete Variante der Klemmhülse 14 von Figur 1 mittels einer Druckfeder 42 in Richtung vom Tambourschild 4 weg gegen eine Distanzmutter 45 verschoben wird. Dabei liegt die Druckfeder an dem gegen das Tambourschild gerichtete Ende an einem Anschlag 44 an, welcher Teil einer Traghülse 43 ist, die im übrigen dieselbe Funktion hat, wie die Traghülse 10 der Figur 1, mit der Ausnahme, dass die genannte Distanzmutter mittels eines Gewindes 47 auf der Traghülse 43 verschiebbar ist. Dabei kann das Mass der Verschiebung an Teilstrichen abgelesen werden, welche in einer an der Traghülse 43 vorgesehenen Nute 46 angebracht sind. Die übrigen Funktionen entsprechen den Funktionen der mit Figur 1 dargestellten Vorrichtung, weshalb sie nicht nochmals beschrieben werden.FIG. 5 shows a variant of the disc wheel 26 from FIG. 1 with a disk wheel 26.3, by displacing a variant of the clamping sleeve 14 from FIG. The compression spring rests on the end directed against the spool shield against a stop 44, which is part of a support sleeve 43, which otherwise has the same function as the support sleeve 10 of FIG. 1, with the exception that the spacer nut mentioned is by means of a thread 47 is displaceable on the support sleeve 43. The degree of displacement can be read from graduation marks which are provided in a groove 46 provided on the support sleeve 43. The other functions correspond to the functions of the device shown in FIG. 1, which is why they are not described again.

Der Vorteil dieser Variante gegenüber der Vorrichtung von Figur 1 besteht darin, dass mit Hilfe der Distanzmutter 45 das Verschieben der Klemmhülse 40 auf der Traghülse 43 von aussen berwerkstelligt werden kann. Das Lösen des Konus ist wie bei Fig. 1 vorgesehen.The advantage of this variant compared to the device of FIG. 1 is that the displacement of the clamping sleeve 40 on the support sleeve 43 can be accomplished from the outside using the spacer nut 45. The cone is released as in FIG. 1.

Die Figur 6 zeigt eine weitere Variante der Vorrichtung von Figur 5, indem hier anstelle der Verschiebbarkeit mittels der Feder 42 eine der Distanzmutter 45 der Figur 5 entsprechende Distanzmutter 52 mit einem Mitnehmerarm 53 versehen ist, an welchem eine Mitnehmerrolle 54 angebracht ist, die praktisch spielfrei in einer Führungsnute 56 des Fusses 57 der Tragscheibe 17.3 geführt ist. Dabei ist der Fuss der Tragscheibe 17.3 mit einem Gleitsitz auf der Traghülse 50 verschiebbar gelagert.FIG. 6 shows a further variant of the device of FIG. 5, in that instead of being displaceable by means of the spring 42, a spacer nut 52 corresponding to the spacer nut 45 of FIG. 5 is provided with a driver arm 53, to which a driver roller 54 is attached, which is practically free of play is guided in a guide groove 56 of the foot 57 of the support disk 17.3. The foot of the support plate 17.3 is slidably mounted on the support sleeve 50.

Um das Mass der Verschiebung der Distanzmutter 52 und damit der Tragscheibe 17.3 zu haben, sind in einer Nute 55 Teilstriche vorgesehen.In order to have the degree of displacement of the spacer nut 52 and thus of the supporting disk 17.3, 55 graduation marks are provided in a groove.

Wenn vorangehend erwähnt wurde, dass die Mitnehmerrolle 54 im wesentlichen spielfrei in der Nute 56 geführt ist, so kann zusätzlich noch erwähnt werden, dass im Prinzip infolge der nach aussen gerichteten axialen Kraft, die zwischen Tragscheibe 17.3 und Konus 20 entsteht, die Mitnehmerrolle 54 im Prinzip immer nur an einer Berührungslinie am Fuss der Tragscheibe 17.3 anliegt.If it was mentioned above that the driving roller 54 is guided essentially free of play in the groove 56, it can additionally be mentioned that, in principle, the driving roller 54 in the result of the outward axial force that arises between the support disk 17.3 and the cone 20 Principle is only applied to a line of contact at the base of the support plate 17.3.
