Description
Die vorliegende Erfindung betrifft eine Anordnung eines Brechzahnes an einer Brechwalze eines Walzenbrechers, wobei an der Brechwalze eine durchgehende Zahnaufnahme mit einer Öffnung angeordnet ist, in die der Brechzahn von einer ersten Seite einführbar und haltend aufnehmbar ist, und wobei eine Spannhülse vorgesehen ist, in der ein Schaft des Brechzahnes unter radialer Verspannung der Spannhülse in der Öffnung aufgenommen ist. Ferner richtet sich die Erfindung auf ein Verfahren zur Anordnung eines Brechzahnes an einer Brechwalze eines Walzenbrechers.The present invention relates to an arrangement of a crushing tooth on a crushing roller of a roll crusher, wherein on the crushing roller a continuous tooth receptacle is arranged with an opening into which the crushing tooth from a first side insertable and holding receivable, and wherein a clamping sleeve is provided in the a shaft of the breaking tooth is received in the opening under radial tension of the clamping sleeve. Furthermore, the invention is directed to a method for arranging a crushing tooth on a crushing roller of a roll crusher.
Walzenbrecher dienen zum Zerbrechen oder zur Zerkleinerung von Brechgut oder sonstigen Materialien, und können nach Art ihrer Ausführung auch als Sizer bezeichnet werden. Der Grundaufbau eines Walzenbrechers weist zumindest zwei gegenläufig rotierende Brechwalzen auf, und zwischen den Brechwalzen wird ein Brechspalt gebildet, in den das zu brechende oder zu zerkleinernde Brechgut beziehungsweise Material eingezogen wird. Auf dem Außenumfang der Brechwalzen sind mehrere Brechzähne angeordnet, die in Zahnaufnahmen haltend aufgenommen und so an der Brechwalze angeordnet sind. Durch die Brechzähne wird das Material direkt zerbrochen oder gegriffen und in den Spalt zwischen die Brechwalzen gezogen. Abhängig vom zu zerbrechenden oder zu zerkleinernden Material wirken daher prozessbedingt sehr hohe Kräfte auf die Brechzähne, sodass die haltende Anordnung der Brechzähne in den Zahnaufnahmen auf dem Außenumfang der Brechwalzen hohen mechanischen Belastungen standhalten muss.Roll crushers are used for breaking or crushing crushed material or other materials, and may also be referred to as sizers according to their type. The basic structure of a roll crusher has at least two counter-rotating crushing rollers, and between the crushing rollers, a crushing gap is formed, in which the crushed material or material to be crushed or crushed is fed. On the outer circumference of the Crushing rollers are arranged a plurality of crushing teeth, which are received in tooth holders holding and are arranged on the crushing roller. The crushing teeth directly break or grasp the material and pull it into the gap between the crushing rollers. Depending on the material to be crushed or comminuted, therefore, very high forces act on the crusher teeth due to the process, so that the holding arrangement of the crusher teeth in the tooth receptacles on the outer circumference of the crushing rollers has to withstand high mechanical loads.

Die
Es ist damit die Aufgabe der vorliegenden Erfindung, eine Anordnung eines Brechzahnes an einer Brechwalze für einen Walzenbrecher zu schaffen, die einfach ausgeführt ist und die hohen mechanischen Belastungen standhalten kann.It is therefore the object of the present invention to provide an arrangement of a crushing tooth on a crushing roller for a roll crusher, which is simple and can withstand the high mechanical loads.
Diese Aufgabe wird ausgehend von einer Anordnung eines Brechzahnes an einer Brechwalze eines Walzenbrechers gemäß dem Oberbegriff des Anspruches 1 in Verbindung mit den kennzeichnenden Merkmalen gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben.This object is achieved on the basis of an arrangement of a crushing tooth on a crushing roller of a roll crusher according to the preamble of claim 1 in conjunction with the characterizing features. Advantageous developments of the invention are specified in the dependent claims.
Die Erfindung schließt die technische Lehre ein, dass ein Schraubelement vorgesehen ist, das mit einem Schraubenschaft im Brechzahn verschraubt ist und mit einem Schraubenkopf in einer Schraubenaufnahme in der Spannhülse einsitzt.The invention includes the technical teaching that a screw is provided which is bolted to a screw shaft in the crushing tooth and is seated with a screw head in a screw receptacle in the clamping sleeve.
Durch die Verwendung einer Spannhülse wird zur Befestigung des Brechzahnes in der Zahnaufnahme ein weiteres Bauteil bereitgestellt, das zur Zahnaufnahme einerseits und zum Brechzahn andererseits einen Bewegungs-Freiheitsgrad besitzt. Der besondere Vorteil der Verwendung der Spannhülse besteht darin, dass diese in einen Spalt zwischen dem Schaft des Brechzahnes und der Öffnung in der Zahnaufnahme eingezogen oder eingedrückt werden kann, während der Brechzahn bereits ruhend in der Öffnung der Zahnaufnahme einsitzt. Beim Einziehen bzw. Eindrücken der Spannhülse in den beispielsweise radial umlaufenden Spalt zwischen dem Schaft und der Öffnung der Zahnaufnahme kann der Schaft in der Öffnung verspannt werden, wobei die radiale Verspannung der Spannhülse in der Öffnung durch einen Konus erzeugt wird, den der Schaft des Brechzahnes gemeinsam mit der Spannhülse bildet. Je weiter die Spannhülse in den radialen, umlaufenden Spalt eingezogen oder eingedrückt wird, desto stärker werden die Verspannungskräfte zwischen der Zahnaufnahme und dem Schaft des Brechzahnes.By using a clamping sleeve, a further component is provided for fastening the crushing tooth in the tooth receptacle, which on the other hand has a degree of freedom of movement for tooth picking on the one hand and for the breaking tooth on the other hand. The particular advantage of using the clamping sleeve is that it can be drawn or pressed into a gap between the shank of the crushing tooth and the opening in the tooth receptacle, while the crushing tooth is already seated in the opening of the tooth receptacle. When pulling or pressing the clamping sleeve in the example radially circumferential gap between the shaft and the opening of the tooth holder of the shaft can be clamped in the opening, wherein the radial clamping of the clamping sleeve is generated in the opening by a cone, the shank of the crushing tooth forms together with the clamping sleeve. The farther the clamping sleeve is drawn or pressed into the radial, circumferential gap, the stronger the clamping forces between the tooth receptacle and the shaft of the crushing tooth.
Der Brechzahn kann einen Zahnkopf aufweisen, der mit einem Anlagebund zur Anlage auf einem die Öffnung umschließenden Anlagerand an der Zahnaufnahme ausgebildet ist. Zerkleinerungskräfte im Betrieb des Walzenbrechers wirken über den Zahnkopf auf den Brechzahn ein, und da der Zahnkopf mit dem Anlagebund am Anlagerand der Zahnaufnahme anliegt, erfolgt eine direkte Ableitung der Zerkleinerungskräfte vom Zahnkopf in die Zahnaufnahme, ohne die eigentliche Befestigung des Brechzahnes in der Zahnaufnahme mechanisch zu belasten. Der Schaft, der sich unterseitig am Zahnkopf befindet und in die Öffnung der Zahnaufnahme hineinragt, wird bei normaler Belastung des Brechzahnes über den Zahnkopf folglich durch die Zerkleinerungskräfte nur noch minimal mechanisch belastet. Ein besonderer Vorteil entsteht dadurch, dass der Anlagebund vollumfänglich um die Längsachse des Brechzahnes am Anlagerand der Zahnaufnahme anliegt, und unabhängig von der Belastungsrichtung des Zahnkopfes erfolgt immer ein Kraftfluss vom Zahnkopf über den Anlagebund und den Anlagerand direkt in die Zahnaufnahme. Die Spannhülse verspannt den Brechzahn so in der Zahnaufnahme, dass der Anlagebund des Zahnkopfes auf den Anlagerand der Zahnaufnahme aufgepresst wird, und die Anordnung des Brechzahnes in der Zahnaufnahme besitzt so eine sehr hohe mechanische Steifigkeit durch die große Anlagefläche zwischen dem Anlagebund und dem Anlagerand.The crushing tooth may have a tooth head, which is formed with an abutment collar for abutment on an abutment edge enclosing the opening on the tooth receptacle. Crushing forces in the operation of the roll crusher act on the tooth tip on the crushing tooth, and there the tooth head with the plant abuts the abutment edge of the tooth holder, there is a direct derivation of the crushing forces from the tooth head into the tooth holder, without mechanically loading the actual attachment of the crushing tooth in the tooth holder. The shaft, which is located on the underside of the tooth head and protrudes into the opening of the tooth socket, is therefore only minimally mechanically loaded by the crushing forces under normal load of the crushing tooth on the tooth head. A particular advantage arises from the fact that the abutment collar lies completely around the longitudinal axis of the crusher tooth on the abutment edge of the tooth receptacle, and regardless of the direction of loading of the tooth head, there is always a force flow from the tooth head over the abutment collar and the abutment edge directly into the tooth receptacle. The clamping sleeve clamps the crusher tooth in the tooth holder so that the abutment collar of the tooth head is pressed onto the abutment edge of the tooth holder, and the arrangement of the crusher teeth in the tooth holder thus has a very high mechanical rigidity due to the large contact surface between the abutment collar and the abutment edge.
Nach einer weiteren vorteilhaften Ausführungsform kann die Spannhülse eine konische Aufnahme aufweisen, in der ein ebenfalls konisch ausgebildeter Schaft des Brechzahnes einsitzt. Dabei kann die Öffnung in der Zahnaufnahme durch eine zylindrische Bohrung gebildet sein, wobei die Spannhülse eine zylindrische Außenkontur aufweist, mit der diese in der Öffnung einsitzt. Der Außendurchmesser der Spannhülse kann dabei dem Durchmesser der Öffnung in der Zahnaufnahme entsprechen. Im Sinne der vorliegenden Erfindung kann jedoch auch der Schaft des Brechzahnes zylindrisch ausgeführt sein, und die Spannhülse kann eine zylindrische Aufnahme, in die der Schaft des Brechzahnes einsitzen kann, besitzen. Dabei kann die Spannhülse außenseitig konisch ausgeführt sein, und die Öffnung in der Zahnaufnahme kann eine konische Öffnung sein, in die die konische Spannhülse eingezogen werden kann. Im Ergebnis ergibt sich eine gleich wirkende Anordnung der Spannhülse zwischen dem Schaft des Brechzahnes und der Zahnaufnahme basierend auf einer betreffend die Gesamtanordnung ebenfalls konischen Spannaufnahme.According to a further advantageous embodiment, the clamping sleeve may have a conical receptacle in which a likewise conical shaft of the crushing tooth is seated. In this case, the opening in the tooth receptacle may be formed by a cylindrical bore, wherein the clamping sleeve has a cylindrical outer contour with which it is seated in the opening. The outer diameter of the clamping sleeve can correspond to the diameter of the opening in the tooth holder. For the purposes of the present invention, however, the shaft of the crushing tooth can be made cylindrical, and the clamping sleeve can have a cylindrical receptacle, in which the shank of the crushing tooth can be seated. In this case, the clamping sleeve can be designed on the outside conical, and the opening in the tooth receptacle can be a conical opening into which the conical clamping sleeve can be retracted. The result is an equally effective arrangement of the clamping sleeve between the shaft of the crushing tooth and the tooth holder based on a respect to the overall arrangement also conical clamping receptacle.
Der Konus des Schaftes und die Aufnahme in der Spannhülse können einen Konuswinkel aufweisen, der einen Wert zwischen beispielsweise 0,2° bis 10°, bevorzugt einen Wert zwischen 1° bis 5° und besonders bevorzugt einen Wert von 2° aufweist. Die Konuswinkel können so beschaffen sein, dass die Spannhülse den Schaft des Brechzahnes selbsthaltend in der Öffnung der Zahnaufnahme hält. Somit sind nicht zwingend Sicherungsmittel erforderlich, um die Spannhülse in ihrer Anordnung zwischen dem Schaft des Brechzahnes und der Zahnaufnahme zu halten.The cone of the shank and the receptacle in the clamping sleeve may have a cone angle which has a value between, for example, 0.2 ° to 10 °, preferably a value between 1 ° to 5 ° and particularly preferably a value of 2 °. The cone angles can be such that the clamping sleeve holds the shaft of the crushing tooth in the opening of the tooth receptacle in a self-holding manner. Thus, not necessarily securing means are required to hold the clamping sleeve in their arrangement between the shaft of the crushing tooth and the tooth holder.
Mit weiterem Vorteil kann die Spannhülse geschlitzt ausgeführt sein, sodass sich in der Spannhülse keine größeren Tangentialspannungen aufbauen können, die der Verspannungswirkung zur Verspannung des Schaftes des Brechzahnes in der Spannhülse entgegenwirken würden. Dabei kann die Spannhülse beispielsweise einen oder mehrere Schlitze aufweisen, die sich in einer Längsrichtung der Spannhülse durch diese wenigstens teilweise hindurch erstrecken.With further advantage, the clamping sleeve can be designed slotted, so that no larger tangential stresses can build up in the clamping sleeve, which would counteract the bracing effect for clamping the shank of the crushing tooth in the clamping sleeve. In this case, the clamping sleeve, for example, have one or more slots, which extend in a longitudinal direction of the clamping sleeve through this at least partially therethrough.
Erfindungsgemäß ist ein Schraubelement vorgesehen, das mit einem Schraubenschaft im Brechzahn verschraubt ist und mit einem Schraubenkopf in einer Schraubenaufnahme in der Spannhülse einsitzt. Durch diese Anordnung eines Schraubelements wird die Spannhülse in den Spalt zwischen dem Schaft des Brechzahnes und der Zahnaufnahme eingezogen beziehungsweise in der eingezogenen Anordnung gesichert.According to the invention, a screw element is provided, which is screwed to a screw shaft in the crusher tooth and is seated with a screw head in a screw receptacle in the clamping sleeve. By virtue of this arrangement of a screw element, the clamping sleeve is drawn into the gap between the shaft of the crushing tooth and the tooth receptacle or secured in the retracted arrangement.
Die Längsrichtung der Spannhülse kann die Rotationsachse der Öffnung in der Zahnaufnahme bilden, und die Längsrichtung kann etwa tangential beabstandet zur Brechwalze verlaufen. Wird die Brechwalze in Rotation versetzt, so zeigt der Zahnkopf des Brechzahnes etwa in Rotationsrichtung, und Material, das zwischen zwei Brechwalzen eingegeben wird, kann so vom Zahnkopf erfasst werden, ohne dass dieser im Wesentlichen seitlich, das heißt quer zur Längsrichtung, belastet wird. Die Zahnaufnahme kann dabei radial überstehend an der Brechwalze angeordnet und insbesondere an diese angeformt oder stoffschlüssig mit dieser verbunden sein. Bekannt sind sogenannte Brechplatten, die auf dem Außenumfang der Brechwalze aufgeschraubt werden können, und die die Zahnaufnahme aufweisen. Die Zahnaufnahme selbst kann jedoch auch direkt mit dem Körper der Brechwalze verbunden sein, beispielsweise mit einer Schweißverbindung oder mit einer Schraubenverbindung.The longitudinal direction of the clamping sleeve may form the axis of rotation of the opening in the tooth receptacle, and the longitudinal direction may extend approximately tangentially spaced from the crushing roller. When the crushing roller is set in rotation, the tooth head of the crushing tooth points approximately in the direction of rotation, and material that is input between two crushing rollers can thus be grasped by the tooth head, without being stressed substantially laterally, ie transversely to the longitudinal direction. The tooth receptacle can be arranged radially projecting on the crushing roller and in particular integrally formed on this or materially connected thereto. Known are so-called crushing plates, which can be screwed onto the outer circumference of the crushing roller, and which have the tooth holder. However, the tooth holder itself can also be used directly be connected to the body of the crushing roller, for example with a welded joint or with a screw connection.
Mit weiterem Vorteil kann der radial umlaufende Sitz des Brechzahns in der Zahnaufnahme an zumindest einer Stelle einen Formschlussbereich aufweisen, der sich beispielsweise an den innen liegenden Bereich des Anlagerandes anschließt. Durch den Formschluss kann ein Verdrehen des Brechzahns in der Zahnaufnahme verhindert werden, was insbesondere im Betrieb der Brechwalze von Vorteil sein kann. Der Formschluss kann erreicht werden durch eine Sicherungsflanke, eine Vielfachverzahnung oder beispielsweise durch einen Vierkant oder ein Polygon, der oder das die Aufnahmeöffnung der Zahnaufnahme im gezeigten Formschlussbereich bildet.With further advantage, the radially encircling seat of the crushing tooth in the tooth receptacle can have at at least one point a form-fit region which, for example, adjoins the inner region of the abutment edge. By the positive connection, a rotation of the crushing tooth can be prevented in the tooth holder, which can be particularly advantageous during operation of the crushing roller. The positive connection can be achieved by a securing flank, a multiple toothing or, for example, by a square or a polygon, which forms the receiving opening of the tooth receptacle in the form-locking region shown.
Die Erfindung richtet sich ferner auf ein Verfahren zur Anordnung eines Brechzahnes an eine Brechwalze eines Walzenbrechers, wobei an der Brechwalze eine durchgehende Zahnaufnahme mit einer Öffnung angeordnet ist, in die der Brechzahn eingeführt wird, wobei eine Spannhülse bereitgestellt wird, die entgegen der Einführrichtung des Brechzahnes in die Öffnung eingeführt wird undin die ein Schaft des Brechzahnes unter radialer Verspannung der Spannhülse in die Öffnung eingezogen wird, und wobei nach dem Einziehen des konischen Schaftes in die Spannhülse die Spannvorrichtung entnommen wird und ein Schraubelement bereitgestellt wird, durch das die verspannte Anordnung des konischen Schaftes in der Spannhülse gesichert wird. Zum Einziehen der Spannhülse in den radialen, umlaufenden Spalt ist damit erfindungsgemäß eine Spannvorrichtung vorgesehen, mit der der vorzugsweise konische Schaft des Brechzahnes unter Aufbringung einer Verspannkraft in die Spannhülse eingezogen wird. Da der Zahnkopf mit seinem Anlagebund gegen den Anlagerand der Zahnaufnahme anliegt, auch bereits, bevor die Spannhülse eingezogen wird, verändert sich die Lage des Brechzahnes in der Zahnaufnahme nicht mehr, und die Spannhülse kann in den Spalt zwischen dem Schaft und der Öffnung in der Zahnaufnahme mit einer Bewegung entgegen der Zahnaufnahme und entgegen den Brechzahn eingezogen werden. Dabei kann die Öffnung in der Zahnaufnahme durchgehend ausgebildet sein, und von der ersten Öffnungsseite kann der Brechzahn und von der gegenüberliegenden, zweiten Öffnungsseite kann die Spannhülse in die Öffnung eingeführt werden.The invention is further directed to a method for arranging a crushing tooth on a crushing roller of a roll crusher, wherein on the crushing roller a continuous tooth receptacle is arranged with an opening into which the crushing tooth is introduced, wherein a clamping sleeve is provided, which is opposite to the insertion direction of the crushing tooth is introduced into the opening and in which a shank of the crushing tooth is retracted under radial tension of the clamping sleeve in the opening, and wherein after retraction of the conical shaft into the clamping sleeve, the clamping device is removed and a screw element is provided, through which the strained arrangement of the conical Shank is secured in the clamping sleeve. For retracting the clamping sleeve in the radial, circumferential gap thus according to the invention a clamping device is provided, with which the preferably conical shank of the crushing tooth is drawn under application of a clamping force in the clamping sleeve. Since the tooth head bears against the abutment edge of the tooth receptacle with its abutment collar, even before the collet is retracted, the position of the crusher tooth in the tooth receptacle no longer changes and the clamping sleeve can enter the gap between the shaft and the opening in the tooth receptacle be retracted with a movement against the tooth picking and against the crushing tooth. In this case, the opening in the tooth receptacle can be formed continuously, and from the first opening side of the Brechzahn and from the opposite, second opening side, the clamping sleeve can be inserted into the opening.
Die Spannvorrichtung kann im einfachsten Fall bereits durch das Schraubelement zwischen der Spannhülse und dem Schaft des Brechzahnes gebildet sein, vorzugsweise kann die Spannvorrichtung jedoch hydraulisch, mechanisch oder auf sonstige Weise ausgeführt sein, und nach dem Einziehen des konischen Schaftes in die Spannhülse kann die Spannvorrichtung entnommen werden und das Schraubelement kann eingesetzt werden, durch das die verspannte Anordnung des konischen Schaftes in der Spannhülse gesichert wird. Schließlich kann die Öffnungsseite, durch die die Spannhülse und das Schraubelement eingeführt wurden, noch mit einem Deckelelement verschlossen werden.The clamping device may be formed in the simplest case already by the screw between the clamping sleeve and the shaft of the crushing tooth, but preferably the clamping device can be performed hydraulically, mechanically or otherwise, and after retraction of the conical shaft into the clamping sleeve, the clamping device can be removed be and the screw can be used by which the strained arrangement of the conical shaft is secured in the clamping sleeve. Finally, the opening side, through which the clamping sleeve and the screw were introduced, can still be closed with a cover element.

In der Zahnaufnahme 11 ist eine Öffnung 12 eingebracht, die beispielhaft zylindrisch ausgebildet ist und sich in Form einer Durchgangsöffnung entlang der gezeigten Längsrichtung 20 durch die Zahnaufnahme 11 hindurch erstreckt. Aus Richtung einer Vorderseite der Zahnaufnahme 11, die in Rotationsrichtung gemäß des gezeigten Rotationspfeiles der Brechwalze 1 vorne liegt, ist ein Brechzahn 10 in die Öffnung 12 der Zahnaufnahme 11 eingeführt. Aus Richtung einer gegenüberliegenden Rückseite ist eine Spannhülse 13 in die Öffnung 12 der Zahnaufnahme 11 eingeführt. Der Brechzahn 10 weist einen konisch ausgebildeten Schaft 14 auf, der sich unterseitig am Zahnkopf 15 erstreckt, wobei der Zahnkopf 15 in Richtung zur Rotation der Brechwalze 1 weist.In the
Die Spannhülse 13 umschließt den konisch ausgebildeten Schaft 14 des Brechzahnes 10, indem der Schaft 14 in einer Aufnahme 18 der Spannhülse 13 eingeführt ist. Die zylindrisch ausgebildete Außenkontur 19 der Spannhülse 13 sitzt dabei in der Öffnung 12 der Zahnaufnahme 11 ein.The clamping
Der Zahnkopf 15 des Brechzahnes 10 weist einen Anlagebund 16 auf, der an einem Anlagerand 17 der Zahnaufnahme 11 plan anliegt, wobei der Anlagerand 17 die Öffnung 12 in der Zahnaufnahme 11 vollumfänglich umschließt. Wirken Zerkleinerungskräfte auf den Zahnkopf 15, so werden diese Kräfte über den Anlagebund 16 und den Anlagerand 17 vom Zahnkopf 15 direkt in die Zahnaufnahme 11 übergeleitet, ohne dass die Zerkleinerungskräfte über den Schaft 14 und die Spannhülse 13 in die Zahnaufnahme 11 geleitet werden müssen.The
Um die Spannhülse 13 in den Spalt zwischen dem Schaft 14 und der Öffnung 12 aufzunehmen, ist eine Spannvorrichtung 25 gezeigt, die als einfachste Ausführungsform einen Dorn 26 und Hülse 27 aufweist, um die Spannhülse 13 in den Spalt einzuziehen. Der Dorn 26 ist in einer Gewindebohrung 33 im Schaft 14 des Brechzahnes 10 eingeschraubt worden, sodass über den Dorn 26 eine Zugkraft auf den Schaft 14 aufgebracht werden kann. Die Hülse 27 ist in ein Gewinde 29 eingeschraubt worden, das sich am Hülsenfuß 30 der Spannhülse 13 befindet. Folglich können sowohl über den Dorn 26 als auch über die Hülse 27 Zug- und auch Druckkräfte in den Schaft 14 beziehungsweise in die Spannhülse 13 eingeleitet werden.In order to receive the clamping
Um die Spannhülse 13 in den Spalt zwischen dem Schaft 14 und der Öffnung 12 einzuziehen, während der Zahnkopf 15 bereits mit dem Anlagebund 16 auf dem Anlagerand 17 der Zahnaufnahme 11 aufliegt, wird auf den Dorn 26 eine Zugkraft und auf die Hülse 27 eine Druckkraft ausgeübt, wobei die jeweiligen Kräfte der Verspannkraft F entsprechen. Die Verspannkraft F kann beispielsweise durch eine hydraulische oder durch eine mechanische Einrichtung aufgebracht werden, die nicht näher gezeigt ist. Die Spannhülse 13 kann dabei soweit in den Spalt eingeschoben werden, bis die erforderliche Verspannkraft F erreicht ist. Durch einen verbleibenden Spalt 31 zwischen einem Absatz 32 in der Öffnung 12 und dem Hülsenfuß 30 der Spannhülse 13 wird sichergestellt, dass die Spannhülse 13 nicht an den Absatz 32 anschlägt, bevor die Verspannkraft F erreicht ist. Der Absatz 32 bildet einen geometrischen Formschluss, sodass sich der Brechzahn 10 nicht in Rotationsrichtung der Brechwalze 1 aus der Öffnung 12 lösen kann.In order to feed the clamping
Um den Aufbau von Tangentialspannungen in der Spannhülse 13 zu vermeiden, weist diese eine geschlitzte Ausführung auf, wobei ein Längsschlitz der Spannhülse 13 in der unteren Seite der Schnittebene liegt, sodass durch die geschlitzte Ausführung die untere Hälfte der Spannhülse 13 durch die Seitenfläche des Schlitzes gebildet ist und sodass die Schraffur entfällt.In order to avoid the buildup of Tangentialspannungen in the clamping
Die beschriebene Spannvorrichtung 25 kann ferner dazu genutzt werden, den Brechzahn 10 wieder aus der Aufnahme 11 und insbesondere aus dem Sitz der Spannhülse 13 zu entnehmen. Die
Alternativ zur gezeigten Spannvorrichtung 25 kann die Spannhülse 13 auch in den Spalt zwischen dem Schaft 14 und der Öffnung 12 eingedrückt werden, beispielsweise durch ein den Brechzahn 10 und die Spannhülse 13 gleichermaßen umgreifendes Werkzeug. Dabei wird das Ziehen und Drücken relativ zwischen dem Brechzahn 10 und der Spannhülse 13 verstanden.Alternatively to the
Der radial umlaufende Sitz des Brechzahns 10 in der Zahnaufnahme 11 kann an gezeigter Stelle einen Formschlussbereich 35 aufweisen, der sich an den innen liegenden Bereich des Anlagerandes 17 anschließt. Durch den Formschluss kann ein Verdrehen des Brechzahns 10 in der Zahnaufnahme 11 verhindert werden, was insbesondere im Betrieb der Brechwalze 1 von Vorteil sein kann. Der Formschluss kann erreicht werden durch eine Sicherungsflanke, eine Vielfachverzahnung oder beispielsweise durch einen Vierkant oder ein Polygon, der oder das die Aufnahmeöffnung der Zahnaufnahme 11 im gezeigten Formschlussbereich 35 bildet.The radially encircling seat of the crushing
Die Erfindung beschränkt sich in ihrer Ausführung nicht auf das vorstehend angegebene lediglich bevorzugte Ausführungsbeispiel.

Sämtliche aus den Ansprüchen, der Beschreibung oder den Zeichnungen hervorgehenden Merkmale und/oder Vorteile, einschließlich konstruktiver Einzelheiten oder räumlicher Anordnungen, können sowohl für sich als auch in den verschiedensten Kombinationen erfindungswesentlich sein. Insbesondere muss der konische Sitz der Spannhülse 13 nicht zwingend zwischen der Spannhülse 13 und dem Schaft 14 gebildet sein, denn der Schaft 14 kann auch zylindrisch ausgeführt sein, sodass auch die Aufnahme 18 in der Spannhülse 13 zylindrisch ausgeführt ist. Dabei kann jedoch die Außenkontur 19 der Spannhülse 13 konisch ausgeführt sein, wobei die konische Außenseite der Spannhülse 13 mit einer entsprechend konischen Öffnung 12 in der Zahnaufnahme 11 korrespondieren kann.The invention is not limited in its execution to the above-mentioned merely preferred embodiment. Rather, a number of variants is conceivable, which makes use of the illustrated solution even with fundamentally different types of use. All of the claims, the description or the drawings resulting features and / or advantages, including structural details or spatial arrangements may be essential to the invention both in itself and in various combinations.
