Abstract

Disclosed is a distance adjusting device comprising an internally threaded outer shell (8) that can be mounted on the machine, an externally threaded inner shell (9), and a display unit (16) for indicating the distance between the two tire rim parts. The two shells are coaxially screwed together by means of the threads thereof while the inner shell (9) can be axially displaced by twisting so as to determine the distance (D) between two tire rim parts (2, 3). In order to quickly adjust the distance without getting injured while creating a compact design for the distance adjusting device, the outer shell (8) can be fixed to the machine so as to be coaxial and rigid relative to the common axis of rotation (1 a) of the two tire rim parts (2,3) while the inner shell (9) is provided with an axial member (25) comprising a final section (28) that protrudes from said shell towards the tire holding area of the machine. A support head (4) for one of the two tire rim parts (2, 3), which is freely rotatable relative to the inner shell (9), is disposed on the protruding final section of said axial member. The subassembly encompassing the axial member (25) and the support head (4) that carries the tire rim part is retained within the outer shell (8) by means of the inner shell (9) so as to be axially displaceable.

Beschreibungdescription
Die Erfindung geht aus von einer Vorrichtung zum Einstellen der Distanz zwischen zwei Reifenfelgenteilen einer Reifenbehandlungsmaschine, wobei die Vorrichtung eine an der Maschine anzuordnende, äußere Hülse mit einem Innengewinde, eine innere Hülse mit einem Außengewinde, wobei beide Hülsen mittels ihrer Gewinde koaxial miteinander verschraubt sind und die innere Hülse gegenüber der äußeren Hülse zum Bestimmen der Distanz durch Verdrehen axial verstellbar ist, und eine Anzeigeeinrichtung zum Anzeigen der Distanz zwischen den beiden Reifenfelgenteilen aufweist.The invention relates to a device for adjusting the distance between two tire rim parts of a tire treatment machine, the device comprising an outer sleeve to be arranged on the machine with an internal thread, an inner sleeve with an external thread, both sleeves being screwed coaxially to one another by means of their threads, and the inner sleeve is axially adjustable relative to the outer sleeve for determining the distance by twisting, and has a display device for displaying the distance between the two tire rim parts.
Eine derartige Distanzeinstellvorrichtung ist in der DE 33 12 618 C2 offenbart, Sie besteht aus zwei koaxial miteinander verschraubten, längs geschlitzten Hülsen, wobei die äußere Hülse an einem Schwenkarm befestigt ist, der seinerseits an einem Rahmenständer der Reifenbehandlungsmaschine schwenkbar angelenkt ist. Nachdem die Distanzeinstellvorrichtung in die Maschine eingeschwenkt worden ist, wird durch Verdrehen der inneren Hülse diese zu der äußeren Hülse axial eingestellt und dadurch ein Axialmaß festgelegt, das sich aus der Länge der äußeren Hülse und dem Längenabschnitt der inneren Hülse, der aus der äußeren Hülse herausragt, zusammensetzt, Dieses Axialmaß bestimmt die jeweils erforderliche Distanz zwischen den beiden, je auf einem Tragkopf angeordneten und gemeinsam einen zu behandelnden Reifen tragenden Felgenteilen der Reifenbehandlungsmaschine. Wenigstens einer der Tragköpfe ist axial verstellbar an einem Ständer der Maschine angeordnet, und zwar mittels eines Pneumatikzylinders, an dessen Kolbenstange der Tragkopf befestigt ist, damit ein zu behandelnder Reifen ein- und ausgespannt werden kann. Auf jeden Fall ist derjenige Tragkopf axial verstellbar ausgebildet, welcher mit der Distanzeinstellvorrichtung zusammenwirkt, Wenn das in Frage kommende Axialmaß an der Distanzeinstellvorrichtung eingestellt worden ist, wird der Tragkopf mit seinem den zu behandelnden Reifen anteilig tragenden Felgenteil zurückgefahren, so dass der Tragkopf an der inneren Hülse anliegt, wobei dann die äußere Hülse an dem Maschinenständer anliegt, Damit ist dann die Arbeitsdistanz zwischen den beiden den Reifen haltenden Felgenteilen festgelegt, so dass der Reifen nun bearbeitet werden kann, z, B. durch einen sogenannten Rauvorgang,Such a distance adjusting device is disclosed in DE 33 12 618 C2. It consists of two coaxially screwed, longitudinally slotted sleeves, the outer sleeve being fastened to a swivel arm, which in turn is pivotably articulated on a frame stand of the tire treatment machine. After the distance adjusting device has been pivoted into the machine, the inner sleeve is rotated axially to the outer sleeve by rotating the inner sleeve, thereby defining an axial dimension that is determined by the length of the outer sleeve and the length of the inner sleeve that protrudes from the outer sleeve , composed, This axial dimension determines the required distance between the two rim parts of the tire treatment machine, each of which is arranged on a support head and together carries a tire to be treated. At least one of the support heads is axially adjustable on a stand of the machine, by means of a pneumatic cylinder to the piston rod of which the support head is attached, so that a tire to be treated can be clamped and unclamped. In any case, that support head is axially adjustable, which cooperates with the distance adjusting device, when the axial dimension in question has been set on the distance adjusting device, the support head is retracted with its part of the rim carrying the tire to be treated, so that the support head on the inner Sleeve rests, the outer sleeve then resting on the machine stand. The working distance between the two rim parts holding the tire is then fixed, so that the tire can now be processed, for example by a so-called roughening process.
Beim praktischen Gebrauch dieser bekannten Distanzeinstellvorrichtung hat sich gezeigt, dass das Hülsenpaar im Falle seiner nicht korrekten Einschwenkung beim Zurückfahren der Kolbenstange wieder herausspringt, so dass das Einschwenken des Hülsenpaares wiederholt werden muss. Des Weiteren besteht die Gefahr, dass, insbesondere beim drehenden Einstellen der inneren Hülse, sich die Bedienungsperson die Finger klemmen kann. Weiterhin hat sich gezeigt, dass für das Einschwenken und Wiederausschwenken des Hülsenpaares bei sorgfältiger Durchführung dieser Vorgänge relativ viel Zeit benötigt wird, was sich auf die gesamte Zykluszeit für die Gesamtbearbeitung des Reifens in der Maschine bezüglich der Erneuerungskosten des Reifens ungünstig auswirkt.In practical use of this known distance adjusting device, it has been shown that the pair of sleeves jumps out again when the piston rod is retracted incorrectly, so that the pair of sleeves must be swiveled in again. Furthermore, there is a risk that, particularly when the inner sleeve is rotated, the operator can pinch his fingers. Furthermore, it has been shown that the pivoting in and out again of the sleeve pair requires a relatively long time if these operations are carried out carefully, which has an unfavorable effect on the total cycle time for the overall machining of the tire in the machine with regard to the tire replacement costs.
Die Aufgabe der Erfindung besteht somit in der Verbesserung einer Distanzeinstellvorrichtung der einleitend angeführten Art, die eine sichere, Verletzungen vermeidende und zeitsparende Distanzeinstellfunktion gewährleistet.The object of the invention is therefore to improve a distance setting device of the type mentioned in the introduction, which ensures a safe, injury-avoiding and time-saving distance setting function.
Die Lösung dieser Aufgabe ist in dem Patentanspruch 1 angeführt.The solution to this problem is set out in claim 1.
Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, dass die maßgebliche Distanz zwischen den beiden, gemeinsam einen zu behandelnden Reifen tragenden Felgenteilen schnell und sicher eingestellt werden kann, ohne dass dabei die Gefahr besteht, dass sich die Bedienungsperson die Finger klemmt oder verletzt, Durch das schnelle und sichere Einstellen der Distanzeinstellvorrichtung wird weiterhin die gesamte Bearbeitungszeit des Reifens, welche beispielsweise für das Rauen oder Belegen eines gerauten Reifens benötigt wird, verkürzt, Ein weiterer Vorteil der erfindungsgemäßen Distanzeinstellvorrichtung besteht darin, dass sie im Vergleich zu einer ein- und ausschwenkbaren Vorrichtung eine kompakte und nicht störende Konstruktion darstellt, die wenig Platz beansprucht.The advantages that can be achieved with the invention consist in particular in that the relevant distance between the two, together one The rim parts to be treated can be adjusted quickly and safely without the risk of the operator pinching or injuring their fingers. By quickly and safely adjusting the distance adjusting device, the entire processing time of the tire, which is necessary, for example, for roughing or covering a roughened tire is required, shortened. Another advantage of the distance adjusting device according to the invention is that compared to a device which can be swung in and out, it is a compact and non-distracting construction which takes up little space.
In einer vorteilhaften Ausgestaltung der erfindungsgemäßen Distanzeinstellvorrichtung ist die innere Hülse relativ zu der äußeren Hülse fixierbar ausgebildet. Hierzu ist die innere Hülse vorzugsweise mit einer äußeren Axialnut von der Länge der maximalen Distanzeinstellstrecke versehen, wobei ein Fixiervorsprung in die äußere Axialnut einrastbar ist. Hierdurch wird bewirkt, dass sich die innere Hülse nach ihrer axialen Einstellung nicht mehr verdrehen kann,In an advantageous embodiment of the distance adjusting device according to the invention, the inner sleeve is designed to be fixable relative to the outer sleeve. For this purpose, the inner sleeve is preferably provided with an outer axial groove of the length of the maximum distance setting distance, wherein a fixing projection can be snapped into the outer axial groove. This has the effect that the inner sleeve can no longer twist after its axial adjustment,
Eine weitere vorteilhafte Ausgestaltung der erfindungsgemäßen Distanzeinstellvorrichtung besteht darin, dass die innere Hülse an ihrem aus der äußeren Hülse in Richtung zu dem Tragkopf für ein Reifenfelgenteil herausragenden Ende eine Handhabe für die axiale Verstellung der inneren Hülse aufweist, Die Handhabe ist vorzugsweise als flanschartige Ausbildung mit einem axialen Betätigungskragen ausgeführt, wobei die äußere Umfangsfläche des Betätigungskragens vorzugsweise griffig ausgebildet ist. Durch diese Ausbildung kann die innere Hülse sicher erfasst und drehbar axial eingestellt werden.A further advantageous embodiment of the distance adjusting device according to the invention is that the inner sleeve at its end protruding from the outer sleeve in the direction of the support head for a tire rim part has a handle for the axial adjustment of the inner sleeve. The handle is preferably in the form of a flange with a axial actuating collar, wherein the outer peripheral surface of the actuating collar is preferably designed to be non-slip. With this design, the inner sleeve can be securely gripped and rotatably adjusted axially.
In einer noch weiteren vorteilhaften Ausgestaltung der erfindungsgemäßen Distanzeinstellvorrichtung besteht ein Merkmal darin, dass der Achskörper der Distanzeinstellvorrichtung im Falle seiner drehfesten Verbindung mit dem Trαgkopf an seinem hinteren Ende einen koaxialen Keilwellenfortsatz aufweist, der axial verschiebbar in eine motorisch drehantreibbare, axial feststehende Keilnutenhülse eingreift, und dass der Tragkopf mit der inneren Hülse verriegelbar und davon entriegelbar ausgebildet ist. Diese Ausbildung der Distanzeinstellvorrichtung ermöglicht zum einen eine motorische Betätigung der Distanzeinstellvorrichtung zum Zwecke der axialen Distanzeinstellung und zum anderen, wenn der Tragkopf von der inneren Hülse entriegelt ist, ein Drehantreiben des zwischen den Felgenteilen eingespannten Reifens zu seiner Behandlung.In a still further advantageous embodiment of the distance adjusting device according to the invention, a feature is that the axle body of the distance adjusting device in the case of its non-rotatable Connection to the support head at its rear end has a coaxial spline extension which engages axially displaceably in a motor-driven, axially fixed spline sleeve, and that the support head can be locked and unlocked from the inner sleeve. This configuration of the distance adjusting device enables motor-driven actuation of the distance adjusting device for the purpose of axial distance adjustment and, on the other hand, when the support head is unlocked from the inner sleeve, the tire clamped between the rim parts can be driven in rotation for its treatment.
Die Erfindung ist nachstehend anhand eines in den anliegenden Zeichnungen dargestellten Ausführungsbeispieles näher erläutert. Es zeigen:The invention is explained below with reference to an embodiment shown in the accompanying drawings. Show it:
Fig. 1 eine teilweise axial geschnittene Ansicht eines zwischen zwei Felgenteilen eingespannten und zu behandelnden Reifens,1 is a partially axial sectional view of a tire clamped between two rim parts and to be treated,

Fig, 1 zeigt einen Reifen 1, der beispielsweise für einen Runderneuerungsvorgang vorbereitet werden soll, z. B, durch einen Rauvorgang, Dieser Reifen wird für die Dauer seiner Raubehandlung in üblicher Weise zwischen zwei um eine gemeinsame Drehachse la drehbaren Felgenteilen 2 und 3 eingespannt, die für die Behandlung auf ein bestimmtes Distanzmaß D voneinander eingestellt werden, Das Felgenteil 2 wird von einem ersten Tragkopf 4 gehalten, während das andere Felgenteil 3 von einem zweiten Tragkopf 5 gehalten wird. Beide Felgenteile sind in üblicher Weise austauschbar, wenn ein Reifen anderer Größe behandelt werden soll, Während ein Reifenkopf in der Regel axial feststehend am Rahmen der nicht weiter gezeigten Reifenbehandlungsmaschine angeordnet ist, ist der andere Tragkopf axial verstellbar an dem Maschinenrahmen angeordnet, um das vorerwähnte Distanzmaß D einstellen zu können. Bei dem hier erläuterten Ausführungsbeispiel ist nur der erste Tragkopf 4 a- xial verstellbar ausgebildet urid wirkt mit der erfindungsgemäßen Distanzeinstellvorrichtung zusammen.Fig. 1 shows a tire 1 which is to be prepared, for example, for a retreading process, e.g. B, by a roughening process, this tire is clamped in the usual way for the duration of its rough treatment between two rim parts 2 and 3 which can be rotated about a common axis of rotation la and which are set to a certain distance D from one another for the treatment, the rim part 2 being made by a first support head 4 held while the other rim part 3 is held by a second support head 5. Both rim parts can be exchanged in the usual way if a tire of a different size is to be treated, While a tire head is generally arranged axially fixed on the frame of the tire treatment machine (not shown further), the other support head is axially adjustable on the machine frame in order to be able to set the aforementioned distance dimension D. In the exemplary embodiment explained here, only the first support head 4 is designed to be axially adjustable and uride interacts with the distance adjusting device according to the invention.
Fig, 2 zeigt teilweise einen Ständer 6 des Rahmens der nicht weiter gezeigten Reifenbehandlungsmaschine, welcher ein rohrförmiges Aufnahmeteil 7 aufweist, welches die gemeinsame Drehachse la für die Felgenteile 2, 3 definiert. An dem Ständer 6 ist über das Aufnahmeteil 7 eine äußere Hülse 8, die ein Innengewinde 8a aufweist, mittels Schrauben 8b starr befestigt, so dass diese Hülse zwar austauschbar, aber weder drehbar noch axial bewegbar ist. In die äußere Hülse 8 greift eine innere Hülse 9 mit ihrem Außengewinde 9a koaxial ein, wie die Figuren 2 und 3 deutlich zeigen. Die Gewinde 8a und 9a sind vorzugsweise ein Trapezgewinde. Während sich das Außengewinde 9a über eine LängeFIG. 2 partially shows a stand 6 of the frame of the tire treatment machine (not shown further), which has a tubular receiving part 7, which defines the common axis of rotation la for the rim parts 2, 3. An outer sleeve 8, which has an internal thread 8a, is rigidly fastened to the stand 6 by means of screws 8b via the receiving part 7, so that this sleeve can be exchanged, but is neither rotatable nor axially movable. In the outer sleeve 8, an inner sleeve 9 engages coaxially with its external thread 9a, as FIGS. 2 and 3 clearly show. The threads 8a and 9a are preferably a trapezoidal thread. While the external thread 9a over a length
« erstreckt, die wenigstens der maximalen Distanz D entspricht, kann sich das Innengewinde 8a über eine wesentlich kürzere Länge erstrecken, wie es in den Figuren 2 und 3 gezeigt ist.«Which corresponds at least to the maximum distance D, the internal thread 8a can extend over a much shorter length, as shown in FIGS. 2 and 3.
Die innere Hülse 9 ragt in Richtung zu dem Reifenhaltebereich der Maschine, d. h. zu dem das Reifenfelgenteil 2 tragenden Tragkopf 4 axial aus der äußeren Hülse 8 heraus und ist an ihrem herausragenden Ende mit einer Handhabe 10 für das axiale Verstellen der inneren Hülse versehen. Diese Handhabe 10 ist als ringförmige, flanschartige Ausbildung mit einem axialen Betätigungskragen 11 ausgeführt. Vorzugsweise ist die äußere Umfangsfläche 12 des Betätigungskragens 11 griffig ausgestaltet, beispielsweise durch eine einfache Rändelung, durch eine Kreuz- rändelung, durch eine Kordelung oder auf andere Weise, In den in den Figuren 2 und 3 gezeigten Ausführungsbeispielen ist die innere Hülse 9 in Ihrem voll ausgefahrenen Zustand gezeigt, was der minimalen einstellbaren Distanz D der Felgenteile 2, 3 entspricht, Man erkennt ferner, dass das Außengewinde 9a der inneren Hülse 9 hierbei nicht aus der äußeren Hülse 8 herausragt, so dass die innere Hülse einen Zwischenlängenabschnitt 13 aufweist, der sich zwischen dem Tragkopf 4 und der äußeren Hülse 8 befindet und gewindefrei ist. Um die Gewinde 8a und 9a der beiden Hülsen 8 bzw. 9 nur mit den axialen Kräften beim Verdrehen der inneren Hülse und des eingespannten Reifens zu belasten und von anderen Tragkräften freizuhalten, sind die beiden Hülsen 8, 9 mittels zweier Gleitlager 14 und 15 gegeneinander abgestützt, Je eines der beiden Gleitlager 14, 15 ist an den beiden Endbereichen der äußeren Hülse 8 fixiert.The inner sleeve 9 protrudes axially out of the outer sleeve 8 in the direction of the tire holding area of the machine, ie towards the support head 4 carrying the tire rim part 2 and is provided at its projecting end with a handle 10 for the axial adjustment of the inner sleeve. This handle 10 is designed as an annular, flange-like design with an axial actuating collar 11. The outer circumferential surface 12 of the actuating collar 11 is preferably configured to be easy to grip, for example by simple knurling, by cross knurling, by cording or in some other way. In the exemplary embodiments shown in FIGS. 2 and 3, the inner sleeve 9 is shown in its fully extended state, which corresponds to the minimum adjustable distance D of the rim parts 2, 3. It can also be seen that the external thread 9a of the inner sleeve 9 is not in this case of the outer sleeve 8 protrudes, so that the inner sleeve has an intermediate length section 13 which is located between the support head 4 and the outer sleeve 8 and is thread-free. In order to load the threads 8a and 9a of the two sleeves 8 and 9 only with the axial forces when rotating the inner sleeve and the clamped tire and to keep them free from other load-bearing capacities, the two sleeves 8, 9 are supported against one another by means of two slide bearings 14 and 15 , One of the two slide bearings 14, 15 is fixed to the two end regions of the outer sleeve 8.
Der inneren Hülse 9 ist eine Anzeigeeinrichtung 16 zum Anzeigen der Distanz D zwischen den beiden Reifenfelgenteilen 2 und 3 zugeordnet, und zwar dem Zwischenlängenabschnitt 13 der inneren Hülse, Diese Anzeigeeinrichtung besteht beispielsweise aus einem Skalenträger 17, der an der äußeren Hülse 8 oder an dem Maschinenständer 6 befestigt sein kann und mit einer Skala 18 für die verschiedenen Distanzen D versehen ist, und aus einem Zeiger 19, Der Zeiger 19 ist zusammen mit der inneren Hülse 9 axial beweglich. Hierzu ist der Zeiger 19 an einem Gleitring 20 befestigt, der am Außenende der inneren Hülse 9 gleitend gelagert ist, derart, dass er axial feststehend an der Hülse 9 befestigt ist, dass sich aber die Hülse 9 in dem Gleitring 20 drehen kann, der sich selbst nicht dreht.The inner sleeve 9 is assigned a display device 16 for displaying the distance D between the two tire rim parts 2 and 3, specifically the intermediate length section 13 of the inner sleeve. This display device consists, for example, of a scale carrier 17 which is attached to the outer sleeve 8 or to the machine stand 6 can be attached and is provided with a scale 18 for the different distances D, and from a pointer 19, the pointer 19 is axially movable together with the inner sleeve 9. For this purpose, the pointer 19 is fastened to a slide ring 20, which is slidably mounted on the outer end of the inner sleeve 9, in such a way that it is axially fixed to the sleeve 9, but that the sleeve 9 can rotate in the slide ring 20, which rotates not turning itself.
Die innere Hülse 9 ist relativ zur äußeren Hülse 8 vorzugsweise fixierbar ausgebildet, um die jeweils eingestellte Distanz D zu sichern. Hierzu ist die innere Hülse 9 gemäß den Figuren 2 und 3 mit einer äußeren Axialnut 21 versehen, die eine Länge aufweist, welche der maximalen Distanzeinstellstrecke entspricht. In diese Axialnut 21 rastet ein Fixiervor- sprung 22 einer Fixierhαndhαbe 23 ein. Somit kann sich die innere Hülse 9 nicht mehr verdrehen, wenn der Fixiervorsprung 22 in die Axialnut eingerastet ist. Die Gewinde 8a und 9a der beiden Hülsen 8, 9 und die Rastfunktion des Fixiervorsprunges 22 sind auf die Skala 18 abgestimmt.The inner sleeve 9 is preferably designed to be fixable relative to the outer sleeve 8 in order to secure the respectively set distance D. For this purpose, the inner sleeve 9 according to FIGS. 2 and 3 is provided with an outer axial groove 21 which has a length which corresponds to the maximum distance setting distance. A fixing device engages in this axial groove 21. jump 22 of a fixation hand 23. Thus, the inner sleeve 9 can no longer twist when the fixing projection 22 is snapped into the axial groove. The threads 8a and 9a of the two sleeves 8, 9 and the locking function of the fixing projection 22 are matched to the scale 18.
Zum weiteren Schutz der Bedienungsperson der Maschine ist der Zwischenlängenabschnitt 13 der inneren Hülse 9 mit einem faltenbalgarti- gen Schutzmantel 24 umgeben. Dieser Schutzmantel ist einerseits an der sich nicht drehenden äußeren Hülse 8 und andererseits an dem sich ebenfalls nicht drehenden Gleitring 20 befestigt. Der Schutzmantel 24 schützt auch die äußere Axialnut 21 der inneren Hülse 9 gegen Verschmutzung, wodurch die Rastfunktion des Fixiervorsprunges 22 jederzeit gewährleistet ist.To further protect the operator of the machine, the intermediate length section 13 of the inner sleeve 9 is surrounded by a bellows-type protective jacket 24. This protective jacket is attached on the one hand to the non-rotating outer sleeve 8 and on the other hand to the sliding ring 20, which is also not rotating. The protective jacket 24 also protects the outer axial groove 21 of the inner sleeve 9 against contamination, as a result of which the locking function of the fixing projection 22 is ensured at all times.
Innerhalb der inneren Hülse 9 ist ein Achskörper 25 vorzugsweise drehbar gelagert, beispielsweise mittels Gleitlager 26 und 27, die in den Endbereichen der inneren Hülse axial gesichert vorgesehen sind. Der Axialkörper 25 weist einen aus der inneren Hülse 9 herausragenden Endabschnitt 28 auf, welcher den ersten Tragkopf 4 trägt. Der Endabschnitt 28 des Achskörpers 25 ist somit dem Reifenhaltebereich der Reifenbehandlungsmaschine zugekehrt, welcher Bereich das an dem Tragkopf 4 gehalterte Felgenteil 2 einschließt. Der Achskörper 25 ist mittels Sicherungsringen 29 in der inneren Hülse 9 axial gesichert, Somit wird der Tragkopf 4 zusammen mit dem Felgenteil 2 axial verstellt, wenn die innere Hülse 9 durch ihre Verdrehung axial verstellt wird,Within the inner sleeve 9, an axle body 25 is preferably rotatably supported, for example by means of slide bearings 26 and 27, which are provided axially secured in the end regions of the inner sleeve. The axial body 25 has an end section 28 which projects from the inner sleeve 9 and which carries the first support head 4. The end section 28 of the axle body 25 thus faces the tire holding area of the tire treatment machine, which area includes the rim part 2 held on the support head 4. The axle body 25 is axially secured in the inner sleeve 9 by means of retaining rings 29. Thus, the support head 4 is axially adjusted together with the rim part 2 when the inner sleeve 9 is axially adjusted by its rotation,
In Fig, 2 ist der Tragkopf 4 so auf dem herausragenden Endabschnitt 28 des Achskörpers 25 gelagert, dass er sich gegenüber der inneren Hülse 9 frei drehen kann, wenn die innere Hülse auf ihr bestimmtes Axialmaß, welches der gewünschten Felgendistanz D entspricht, eingestellt ist, Im Übrigen kann der Tragkopf 4 auf dem Endabschnitt 28 des Achskörpers 25 frei drehbar oder auch drehfest, letzteres beispielsweise mittels einer Pαssfeder-Nut-Verbindung 30, ausgebildet sein, Ist der zu behandelnde Reifen 1 zwischen den beiden in bekannter Form aufgebauten Felgenteilen 2 und 3 mit der gewünschten Distanz D eingespannt (Fig. 1), wird der Reifen mittels eines gesonderten Antriebes (nicht dargestellt) drehend angetrieben, damit er behandelt werden kann, z, B. durch einen Rauvorgang, Ein solcher Antrieb kann beispielsweise den zweiten Tragkopf 5, welcher das Felgenteil 3 trägt, drehend antreiben,2, the support head 4 is mounted on the protruding end section 28 of the axle body 25 in such a way that it can rotate freely with respect to the inner sleeve 9 when the inner sleeve is set to its specific axial dimension, which corresponds to the desired rim distance D, In addition, the support head 4 on the end section 28 of the axle body 25 can rotate freely or also non-rotatably, the latter for example by means of a Key-and-groove connection 30, if the tire to be treated 1 is clamped between the two rim parts 2 and 3 constructed in a known manner with the desired distance D (FIG. 1), the tire is driven by a separate drive (not shown). driven in rotation so that it can be treated, for example by a roughening process. Such a drive can, for example, drive the second support head 5, which carries the rim part 3, in rotation,
Die axiale Verstellung der inneren Hülse 9 erfolgt nach der Ausführungsform nach Fig. 2 von Hand auf folgende Weise, Nachdem die Fixierhandhabe 23 entriegelt worden ist, wird die Handhabe 10 der inneren Hülse 9 von der Bedienungsperson betätigt, indem die Person die äußere Umfangsfläche 12 der Handhabe 10 ergreift und diese Handhabe entsprechend dem erforderlichen Distanzmaß D verdreht, so dass sich die Hülse 9 axial verstellt, wobei das Distanzmaß D an der Skala 18 ablesbar ist, Dann wird die Fixierhandhabe 23 wieder in die Verriegelungsposition eingestellt.The axial adjustment of the inner sleeve 9 is carried out according to the embodiment of FIG. 2 by hand in the following manner, after the fixing handle 23 has been unlocked, the handle 10 of the inner sleeve 9 is actuated by the operator by the person the outer peripheral surface 12 of the Grips handle 10 and rotates this handle according to the required distance D, so that the sleeve 9 is axially adjusted, the distance D being read on the scale 18, then the fixing handle 23 is set again in the locking position.
Fig. 3 zeigt eine Ausführungsform der Distanzeinstellvorrichtung, bei der die innere Hülse 9 motorisch axial verstellt werden kann. Hierzu ist der in der inneren Hülse 9 gelagerte Achskörper 25 an seinem hinteren Ende mit einem koaxialen Keilwellenfortsatz 31 versehen, Dieser Fortsatz greift axial verschiebbar in eine motorisch drehantreibbare, axial feststehende Keilnutenhülse 32 ein, die im gezeigten Beispiel Bestandteil eines Getriebemotors 33 ist, Des Weiteren ist der erste Tragkopf 4 mit der inneren Hülse 9 mit Hilfe von schematisch angedeuteten Blockiermitteln 34 blockierbar. In diesem Fall ist es erforderlich, dass der Tragkopf 4 des Weiteren mit dem Achskörper 25 an dessen herausragendem Endabschnitt 28 drehfest verbunden ist, beispielsweise mittels der vorstehend erwähnten Passfeder-Nut-Verbindung 30. Soll eine motorische Axialverstellung der inneren Hülse 9 und damit des Felgenteiles 2 für die Einstellung der erforderlichen Felgendistanz D vorgenommen werden, so wird der Trαgkopf 4 mit der inneren Hülse 9 durch Betätigen der Blockiermittel 34 blockiert. Sodann wird die Keilnutenhülse 32 mittels des Motors 33 drehend angetrieben, so dass die innere Hülse 9 durch den Tragkopf 4, der drehfest auf dem Achskörper 25 sitzt, drehend mitgenommen wird. Nach erfolgter Distanzeinstellung werden die Blockiermittel 34 wieder entriegelt, so dass dann der Tragkopf 4 und damit das Felgenteil 2 sich unabhängig von der inneren Hülse 9 drehen oder in gewünschter Weise drehend angetrieben werden können,Fig. 3 shows an embodiment of the distance adjusting device in which the inner sleeve 9 can be axially adjusted by a motor. For this purpose, the axle body 25 mounted in the inner sleeve 9 is provided at its rear end with a coaxial spline extension 31. This extension engages axially displaceably in a motor-driven, axially fixed spline sleeve 32, which in the example shown is part of a geared motor 33, furthermore the first support head 4 with the inner sleeve 9 can be blocked with the aid of schematically indicated blocking means 34. In this case, it is necessary that the support head 4 is further connected to the axle body 25 at its protruding end section 28 in a rotationally fixed manner, for example by means of the key-and-groove connection 30 mentioned above. A motor-driven axial adjustment of the inner sleeve 9 and thus of the rim part is intended 2 for setting the required rim distance D, the Carrier head 4 with the inner sleeve 9 blocked by actuating the blocking means 34. Then the spline sleeve 32 is driven in rotation by means of the motor 33, so that the inner sleeve 9 is rotatably carried along by the support head 4, which is non-rotatably seated on the axle body 25. After the distance has been set, the blocking means 34 are unlocked again, so that the support head 4 and thus the rim part 2 can rotate independently of the inner sleeve 9 or can be driven to rotate in the desired manner,
Bei der Ausführungsform der Distanzeinstellvorrichtung gemäß Fig, 3 bietet es sich an, auch den zwischen den beiden Felgenteilen 2 und 3 zur Bearbeitung behandlungsbereit eingespannten Reifen weiter durch den Getriebemotor 33 drehend anzutreiben, Hierzu brauchen lediglich die Blockiermittel 34 nach Distanzeinstellung entriegelt zu werden. Der Motor 33 ist dann so ausgelegt bzw. dimensioniert, dass er auch die erforderliche Antriebsleistung erbringt, die für den Drehbetrieb des eingespannten Reifens während seiner Behandlung erforderlich ist,In the embodiment of the distance adjusting device according to FIG. 3, it makes sense to also continue to drive the tire clamped between the two rim parts 2 and 3 for processing in a manner ready for treatment by the gear motor 33. All that is required is to unlock the blocking means 34 after the distance has been set. The motor 33 is then designed or dimensioned such that it also provides the drive power required for the rotating operation of the clamped tire during its treatment,
Die vorstehend beschriebene Distanzeinstellvorrichtung kann für alle Reifenbehandlungsmaschinen, bei denen der zu behandelnde Reifen in üblicher Weise zwischen zwei Felgenteilen während seiner Behandlung eingespannt gehalten wird, angewendet werden, Weitere Beispiele außer Raumaschinen sind Belegemaschinen, Beulenprüfmaschinen und Schleifmaschinen, wobei diese Aufzählung nicht abschließend ist, Als zu behandelnde Reifen kommen Luftreifen aller Art, Form und Größe in Frage, wie sie beispielsweise für Pkws, Lkws, Busse, Schwerlastfahrzeuge und Flugzeuge verwendet werden, The distance setting device described above can be used for all tire treatment machines in which the tire to be treated is clamped in the usual way between two rim parts during its treatment. Further examples besides space machines are covering machines, dent testing machines and grinding machines, but this list is not exhaustive, as Tires to be treated can be pneumatic tires of all types, shapes and sizes, such as those used for cars, trucks, buses, heavy goods vehicles and airplanes,
