Description

Die Erfindung betrifft einen Walzenstuhl mit wenigstens einer aushebbaren Walze, einem Lagerschaft zur Lagerung eines Endes der Walze in einer bestimmungsgemäßen Lage, einem zur Fixierung des Lagerschaftes am Walzenstuhl an dem Lagerschaft vorgesehenen radial expandierbaren Expansionsabschnitt, einem vom Lagerschaft getragenen, axial belastbaren, radialen Lager zur Aufnahme des Endes der Walze und mit einer Stellschraube, durch deren entsprechende Betätigung der Expansionsabschnitt expandierbar ist.The invention relates to a roller mill with at least one liftable roller, a bearing shaft for supporting one end of the roller in a predetermined position, a provided for fixing the bearing shaft on the roller mill on the bearing shaft radially expandable expansion section, a bearing shaft, axially loaded, radial bearing for Receiving the end of the roller and with a screw, through the corresponding actuation of the expansion section is expandable.

Walzenstühle dieser Art werden bevorzugt in der graphischen Industrie eingesetzt und sind hier beispielsweise Hauptbestandteile von Falzwerken für flächige Druckprodukte. Ein Walzenstuhl mit den eingangs genannten Merkmalen ist aus DE 93 02 952 U1 bekannt. Ein hierin offenbarter Lagerschaft weist zwar in dessen Expansionsabschnitt einen axial fixierten und unter axialer Stauchung radial expandierbaren Ringkörper auf. Der Ringkörper ist auf einen Absatz an einem der Walze abgewandten Ende des Lagerschaftes aufgeschoben und wird mittels einer axial in dieses Ende eindrehbaren Schraube mit einer unterlegten Topfscheibe axial gestaucht. Als hierzu geeignete Schraube kommt insbesondere eine solche mit Außen- oder Innensechskantkopf in Betracht, um das zur hinlänglichen Stauchung des Ringkörpers an der Schraube erforderliche Drehmoment aufzubringen.Rolling chairs of this type are preferably used in the graphic arts industry and are here, for example, the main components of folding units for flat printed products. A roller mill with the features mentioned is known from DE 93 02 952 U1. Although a bearing shaft disclosed herein has in its expansion section an axially fixed and under axial compression radially expandable annular body. The annular body is pushed onto a shoulder on an end of the bearing shaft facing away from the roller and is axially compressed by means of a screw which can be screwed axially into this end with an underlying cup wheel. As a suitable screw in particular such comes with external or hexagon head into consideration to apply the required for sufficient compression of the annular body on the screw torque.

Die Betätigung der Schraube im Sinne des axialen Stauchens des Ringkörpers bringt es jedoch nicht zwangsläufig mit sich, dass die Walze axial spielfrei gelagert wird.The actuation of the screw in the sense of axial compression of the annular body, however, does not necessarily entail that the roller is mounted axially free of play.

Der Erfindung liegt die Aufgabe zugrunde, einen Walzenstuhl der eingangs genannten Art derart auszubilden, dass die Fixierung des Lagerschaftes und die axial spielfreie Lagerung der in diesem gelagerten aushebbaren Walze mit ein und demselben Betätigungsmittel und in einem Arbeitsgang erfolgen kann.The invention has the object of providing a roller mill of the type mentioned in such a way that the fixation of the bearing shaft and the axially play-free storage of the mounted in this liftable roller can be done with one and the same actuating means and in one operation.

Zur Lösung dieser Aufgabe ist im entsprechenden Lagerschaft ein axial verstellbares Druckstück angeordnet, welches in der bestimmungsgemäßen Lage des Endes der Walze unter der Wirkung der Stellschraube derart gegen das Lager angestellt ist, dass sich dieses axial an der Walze abstützt.To solve this problem, an axially adjustable pressure piece is arranged in the corresponding bearing shaft, which is employed in the intended position of the end of the roller under the action of the screw against the bearing, that this is axially supported on the roller.

Bei dieser Ausgestaltung stellt die Stellschraube das Betätigungsmittel zur Fixierung des Lagerschaftes und zur axial spielfreien Lagerung der Walze in ein und demselben Arbeitsgang dar. Der Begriff "Walze" steht hierbei für Walzen sowie für Wellen, wie beispielsweise Messerwellen, oder Achsen für unterschiedlichste Verwendungszwecke.In this embodiment, the set screw represents the actuating means for fixing the bearing shaft and the axially play-free mounting of the roller in one and the same operation. The term "roller" here stands for rollers and shafts, such as knife shafts, or axes for a variety of uses.

Die Merkmale des Erfindungsgegenstandes und von Ausbildungen desselben sind den beigefügten Zeichnungen und den darauf Bezug nehmenden nachfolgenden Erläuterungen entnehmbar.The features of the subject invention and of embodiments thereof are the appended drawings and the subsequent explanations taken to be taken.

Ein in Fig. 1 beispielhaft in schematischer Darstellung wiedergegebener Walzenstuhl umfasst paarweise angeordnete Falzwalzen 1 und diesen nachgeordnete Messerwellen 2 sowie Falztaschen 3, und bildet somit ein Stauchfalzwerk. Die Falzwalzen 1 und die Messerwellen 2 werden von hier nicht dargestellten Lagerhebeln getragen, die ihrerseits auf ebenfalls nicht dargestellte Weise justierbar an Seitenwänden 4 angeordnet sind.A roll mill recited by way of example in a schematic representation in FIG. 1 comprises folding rolls 1 arranged in pairs and these knife shafts 2 and folding pockets 3 arranged in pairs, thus forming an upsetting folder. The folding rollers 1 and the blade shafts 2 are supported by bearing levers, not shown here, which are in turn arranged in a manner not shown adjustable on side walls 4.

In Fig. 2 ist am Beispiel einer der Messerwellen 2 eine aushebbare Anordnung derselben dargestellt. Ein in der Figur rechtes Ende der Messerwelle 2 ist axial auf einen Lagerzapfen aufgeschoben, der in einem ersten der bereits genannten und hier andeutungsweise erkennbaren Lagerhebel 6 und 6', und zwar in dem bruchstückweise dargestellten Lagerhebel 6 mittels eines ein Festlager darstellenden Wälzlagers aufgenommen ist.2, a liftable arrangement of the same is shown using the example of one of the cutter shafts 2. A in the figure right end of the blade shaft 2 is pushed axially onto a bearing journal, which is accommodated in a first of the already mentioned and here suggestively recognizable bearing lever 6 and 6 ', in the fragmentary illustrated bearing lever 6 by means of a bearing bearing rolling bearing.

Ein in der Figur linkes Ende der Messerwelle 2 ist mittels eines axial belastbaren radialen Lagers 7.1 - hier in Form eines Wälzlagers - in einem Lagerschaft 7 aufgenommen. Der Lagerschaft 7 dient der Lagerung des genannten linken Endes der Messerwelle 2 in einer bestimmungsgemäßen Lage. Hierunter wird eine Lage verstanden, in der die Messerwelle 2 ihre Funktion erfüllen kann und axial spielfrei aufgenommen ist.An in the figure left end of the blade shaft 2 is received by means of an axially resilient radial bearing 7.1 - here in the form of a rolling bearing - in a bearing shaft 7. The bearing shaft 7 serves to support the said left end of the knife shaft 2 in a proper position. This is understood to mean a position in which the blade shaft 2 can fulfill its function and is received axially free of play.

Der Lagerschaft weist einen radial expandierbaren Expansionsabschnitt 8 auf. In diesem Expansionsabschnitt 8 trägt der Lagerschaft 7 eine in der Weise elastisch verformbare Druckhülse 9, dass sich diese unter axialer Druckspannung radial ausdehnt. Diese radiale Ausdehnung wird dazu genutzt, den Lagerschaft an dessen Expansionsabschnitt 8 in einer Lagerbohrung 11 eines zweiten der genannten Lagerhebel 6 und 6', und zwar des Lagerhebels 6', zu fixieren.The bearing shaft has a radially expandable expansion section 8. In this expansion section 8, the bearing shaft 7 carries an elastically deformable pressure sleeve 9 in such a way that it radially expands under axial compressive stress. This radial expansion is used the bearing shaft at the expansion portion 8 in a bearing bore 11 of a second of said bearing levers 6 and 6 ', namely the bearing lever 6', to fix.

Die Druckhülse 9 ist auf einen der Messerwelle 2 abgewandten Absatz des Lagerschaftes 7 aufgeschoben und in der von der Messerwelle 2 weg weisenden Richtung an einer stirnseitig am Lagerschaft 7 befestigten Anschlagscheibe 10 axial angeschlagen. Der Querschnitt der Druckhülse 9 überbrückt einen axialen Abschnitt eines Ringraumes zwischen dem genannten Absatz des Lagerschaftes 7 und der diese aufnehmenden Lagerbohrung 11.The pressure sleeve 9 is pushed onto a blade shaft 2 facing away from the shoulder of the bearing shaft 7 and axially struck in the direction away from the blade shaft 2 direction on a front side of the bearing shaft 7 stop plate 10. The cross-section of the pressure sleeve 9 bridges an axial section of an annular space between said shoulder of the bearing shaft 7 and the bearing bore 11 receiving it.

An die der Messerwelle 2 zugewandte Stirnseite der Druckhülse 9 ist ein in den genannten Ringraum eingesetzter Druckring 12 angestellt. In der Nachbarschaft des Druckringes 12 ist der Lagerschaft 7 mit einer diametralen Ausnehmung 13 versehen, in welche ein Druckbalken 14 eingesetzt ist, der an die der Messerwelle 2 zugewandte Stirnseite des Druckringes 12 angestellt ist.At the knife shaft 2 facing end face of the pressure sleeve 9, a pressure ring 12 inserted into said annulus is employed. In the vicinity of the pressure ring 12 of the bearing shaft 7 is provided with a diametrical recess 13, in which a pressure bar 14 is inserted, which is employed on the blade shaft 2 facing the end face of the pressure ring 12.

In einer zentralen Axialbohrung des in Richtung auf die Messerwelle 2 auf die diametrale Ausnehmung 13 folgenden Abschnittes des Lagerschaftes 7 ist ein mit einer Längsnut 15' versehner erster Stößel 15 geführt. Dieser ist mittels einer quer in den Lagerschaft 7 eingeschraubten und in die Längsnut 15' eingreifenden Führungsschraube 16 gegen Verdrehen gesichert. An einem der Messerwelle 2 abgewandten Ende des Stößes 15 bildet dieser einen Zapfen 15" aus, der in eine entsprechende Bohrung des Druckbalkens 14 eingreift und diesen trägt. Eine durch den Zapfen 15" am Stößel 15 ausgebildete Schulter ist in Anlage an dem Druckbalken 14.In a central axial bore of the following in the direction of the blade shaft 2 on the diametrical recess 13 portion of the bearing shaft 7 with a longitudinal groove 15 'versehner first plunger 15 is guided. This is secured by means of a transverse screwed into the bearing shaft 7 and in the longitudinal groove 15 'engaging guide screw 16 against rotation. At an end of the butt 15 facing away from the blade shaft 2, this forms a pin 15 ", which engages in and supports a corresponding bore of the pressure beam 14. A shoulder formed on the tappet 15 by the pin 15" is in contact with the pressure beam 14.

Eine quer in den Lagerschaft 7 eingeschraubte Stellschraube 17 weist einen konischen Abschnitt auf und steht in diesem jedenfalls in der bestimmungsgemäßen Lage der Messerwelle in Kontakt mit einer an den Konuswinkel der Stellschraube 17 angepassten, schrägen und der Messerwelle 2 zugewandten Stirnfläche des Stößels 15.A screwed transversely into the bearing shaft 7 screw 17 has a conical portion and is in this case in any case in the intended position of the blade shaft in contact with an adapted to the cone angle of the adjusting screw 17, oblique and the blade shaft 2 facing end face of the plunger 15th

In der genannten zentralen Axialbohrung des Lagerschaftes 7 ist auf der der Messerwelle 2 zugewandten Seite des Lagerschaftes 7 ein mit einer Längsnut 18.2 versehener zweiter Stößel 18.1 geführt. Dieser zweite Stößel 18.1 ist wiederum mittels einer quer in den Lagerschaft 7 eingeschraubten und in die Längsnut 18.2 eingreifenden Führungsschraube 16 gegen Verdrehen gesichert.In the said central axial bore of the bearing shaft 7, a second plunger 18.1 provided with a longitudinal groove 18.2 is guided on the side of the bearing shaft 7 facing the blade shaft 2. This second plunger 18.1 is in turn secured against rotation by means of a transverse screwed into the bearing shaft 7 and engaging in the longitudinal groove 18.2 guide screw 16.

Der konische Abschnitt der Stellschraube 17 steht in der bestimmungsgemäßen Lage der Messerwelle 2 weiterhin in Kontakt mit einer an den Konuswinkel der Stellschraube 17 angepassten schrägen und der Messerwelle 2 abgewandten Stirnfläche des zweiten Stößels 18.1.The conical portion of the screw 17 is in the intended position of the blade shaft 2 continues to be in contact with a matched to the cone angle of the adjusting screw 17 oblique and the blade shaft 2 facing away from the end face of the second plunger 18.1.

Der zweite Stößel 18.1 trägt an seinem der Messerwelle 2 zugewandten Ende einen Teller 18.3, der in eine im Lagerschaft 7 vorgesehene Lagerbohrung eingepasst ist, die zur Aufnahme des bereits genannten Lagers 7.1 für das in Figur 2 linke Ende der Messerwelle 2 ausgebildet ist.The second plunger 18.1 carries at its end facing the blade shaft 2 a plate 18.3, which is fitted in a provided in the bearing shaft 7 bearing bore, which is designed to receive the aforementioned bearing 7.1 for the left in Figure 2 end of the blade shaft 2.

Eine Feder 19 ist einerseits an der der Messerwelle 2 zugewandten Seite des Tellers 18.3 und andererseits am Außenring des hier als Wälzlager ausgebildeten Lagers 7.1 abgestützt. In der bestimmungsgemäßen Lage der Messerwelle 2 sitzt der Innenring des Wälzlagers 7.1 auf einem eine Wellenschulter der Messerwelle 2 bildenden Absatz derselben und ist unter der Wirkung der Feder 19 gegen die Wellenschulter gedrückt, wobei die Feder 19 seitens des zweiten Stößels 18.1 über den Teller 18.3 durch entsprechende Drehung der Stellschraube 17 gespannt ist. Der zweite Stößel 18.1 bildet somit mit dem daran vorgesehenen Teller 18.3 ein im Lagerschaft 7 angeordnetes, axial verstellbares Druckstück 18, welches in der bestimmungsgemäßen Lage des Endes der Messerwelle 2 unter der Wirkung der Stellschraube 17 derart gegen das Lager 7.1 angestellt ist, dass sich dieses axial an der Messerwelle 2 abstützt.A spring 19 is supported on the one hand on the blade shaft 2 facing side of the plate 18.3 and on the other hand on the outer ring of the trained here as a bearing bearing 7.1. In the intended position of the blade shaft 2, the inner ring of the roller bearing 7.1 sits on a shaft shoulder of the blade shaft 2 forming paragraph of the same and is pressed under the action of the spring 19 against the shaft shoulder, wherein the spring 19 by the second plunger 18.1 on the plate 18.3 corresponding rotation of the screw 17 is stretched. The second plunger 18.1 thus forms with the plate provided thereon 18.3 arranged in the bearing shaft 7, axially adjustable pressure member 18 which is employed in the intended position of the end of the blade shaft 2 under the action of the screw 17 against the bearing 7.1 that this is axially supported on the blade shaft 2 ,

In der Figur 2 ist dieser gespannte Zustand wiedergegeben.In Figure 2, this strained state is reproduced.

Der erste Stößel 15 und der zweite Stößel 18.1 sind so dimensioniert, dass die Stellschraube 17 bei deren Betätigung im Sinne des Spannens der Feder 19, die am zweiten Stößel 18.1 ausgebildete schräge Stirnfläche nach der am ersten Stößel 15 ausgebildeten Stirnfläche erreicht. Hieraus ergibt sich während der entsprechenden Betätigung der Stellschraube 17 zunächst eine Fixierung des Lagerschaftes 7 am Lagerhebel 6' und anschließend ein Herausdrücken von axialem Spiel zwischen einerseits den Lagerhebeln 6 und 6' und andererseits der Messerwelle 2.The first plunger 15 and the second plunger 18.1 are dimensioned so that the adjusting screw 17, when actuated in the sense of tensioning the spring 19, reaches the oblique face formed on the second plunger 18.1 after the end face formed on the first plunger 15. This results during the corresponding operation of the adjusting screw 17, first a fixation of the bearing shaft 7 on the bearing lever 6 'and then a pushing out of axial play between on the one hand the bearing levers 6 and 6' and on the other hand, the knife shaft.

Es versteht sich, dass der entsprechenden Betätigung der Stellschraube 17 das Aufschieben des Lagerschaftes 7, genauer des in diesem angeordneten Lagers 7.1 auf den diesem zugewandten Absatz der Messerwelle 2 vorausgeht.It is understood that the corresponding actuation of the adjusting screw 17 precedes the sliding of the bearing shaft 7, more precisely of the arranged in this bearing 7.1 on this facing paragraph of the blade shaft 2.

Eine derart in den Lagerschaft 7 eingeschraubte Sicherungsschraube 20, dass deren Kopf die Stellschraube 17 teilweise überdeckt, dient als Verliersicherung für die Stellschraube 17.Such screwed into the bearing shaft 7 locking screw 20 that the head of the screw 17 partially covers, serves as a captive for the screw 17th

Zum Ausheben der Messerwelle 2 wird die Stellschraube 17 gelöst und somit insbesondere die Fixierung des Lagerschaftes 7 im Lagerhebel 6' aufgehoben. Hiernach wird der Lagerschaft 7 entlang der Lagerbohrung 11 von dem Absatz der Messerwelle 2 abgezogen. Hierzu ist der Lagerschaft 7 auf eine entsprechende Länge desselben an den Durchmesser der Lagerbohrung 11 angepasst.To lift the blade shaft 2, the screw 17 is released and thus in particular the fixation of the bearing shaft 7 in the bearing lever 6 'repealed. Thereafter, the bearing shaft 7 is withdrawn along the bearing bore 11 of the paragraph of the blade shaft 2. For this purpose, the bearing shaft 7 on a corresponding length thereof adapted to the diameter of the bearing bore 11.

Die Fig. 3 zeigt einen zur Lagerung der Messerwelle 2 vorgesehenen Lagerschaft 7' in einer zu Fig. 2 alternativen Ausgestaltung, und zwar in Form einer hydraulischen Variante.FIG. 3 shows a bearing shaft 7 'provided for supporting the blade shaft 2 in an alternative embodiment to FIG. 2, specifically in the form of a hydraulic variant.

Der Lagerschaft 7' ist in einem entspannten Zustand analog zur Ausgestaltung gemäß Fig. 2 in Längsrichtung der Lagerbohrung 11 des zweiten Lagerhebels 6' verschiebbar und er trägt in analoger Weise das Lager 7.1 zur Aufnahme des in Fig. 2 linken Endes der Messerwelle 2, allerdings mit den Unterschieden, dass auf die der Messerwelle 2 zugewandte Seite des Außenringes des als Wälzlager ausgebildeten Lagers 7.1 zunächst eine federnde Ausgleichsscheibe 7.2 und erst danach ein Sicherungsring 7.3 als mittelbarer axialer Anschlag für den Außenring des Lagers 7.1 folgt, dass sich diese Ausgleichsscheibe 7.2 einerseits an dem genannten Außenring und andererseits an dem Sicherungsring 7.3 abstützt und dass auf der der Messerwelle 2 abgewandten Stirnseite des Lagers 7.1 keine Feder angeordnet ist.The bearing shaft 7 'is displaceable in a relaxed state analogous to the embodiment of FIG. 2 in the longitudinal direction of the bearing bore 11 of the second bearing lever 6' and he carries in an analogous manner the bearing 7.1 for receiving the left in Fig. 2 end of the blade shaft 2, however with the differences that on the blade shaft 2 facing side of the outer ring of the bearing designed as a bearing bearing 7.1 initially a resilient sheave 7.2 and only then a locking ring 7.3 as indirect axial stop for the outer ring of the bearing 7.1 follows that this shim 7.2 on the one hand the said outer ring and on the other hand on the retaining ring 7.3 is supported and that on the blade shaft 2 facing away from the end face of the bearing 7.1 no spring is arranged.

Zur Fixierung des Lagerschaftes 7' in der Lagerbohrung 11 (siehe Fig. 2) und zum Herausdrücken von axialem Spiel zwischen einerseits den Lagerhebeln 6 und 6' und andererseits der Messerwelle 2 ist der Lagerschaft 7' mit einem geschlossenen Hydrauliksystem versehen. Dieses umfasst eine einseitig offene radiale Gewindebohrung und eine in diese eingeschraubte Gewindebuchse 21, die in einem beim Einschrauben vorauseilenden Abschnitt derselben einen letztlich in Einschraubrichtung offenen Zylinder 22 ausbildet. Ein nachlaufender Abschnitt der Gewindebuchse 21 weist ein axiales Innengewinde auf, in welches vom offenen Ende des Zylinders 22 her eine Stellschraube 17' in Form einer Durchgangsschraube eingeschraubt ist; das in Einschraubrichtung der Stellschraube 17' weisende Ende von deren Gewindeschaft ist somit in situ zugänglich und es ist zur Betätigung der Stellschraube 17' mittels eines Schraubendrehers ausgebildet.For fixing the bearing shaft 7 'in the bearing bore 11 (see Fig. 2) and for pushing out axial play between on the one hand the bearing levers 6 and 6' and on the other hand the blade shaft 2, the bearing shaft 7 'is provided with a closed hydraulic system. This comprises a unilaterally open radial threaded bore and a threaded bushing 21 screwed into the latter, which in a screwing-ahead section thereof forms a cylinder 22 which is ultimately open in the screwing-in direction. A trailing portion of the threaded bushing 21 has an axial internal thread, in which from the open end of the cylinder 22 ago a set screw 17 'in shape a through-bolt is screwed; in the screwing of the screw 17 'facing end of the threaded shaft is thus accessible in situ and it is to actuate the screw 17' formed by means of a screwdriver.

Das die Stellschraube 17' aufnehmende Innengewinde hat einen kleineren Durchmesser als die lichte Weite des Zylinders 22 und bildet somit mit diesem eine Schulter aus, an welche ein als Bund ausgebildeter Schraubenkopf der Stellschraube 17' in einem später noch näher erläuterten drucklosen Betriebszustand des Hydrauliksystems angeschlagen ist.The adjusting screw 17 'receiving internal thread has a smaller diameter than the inside diameter of the cylinder 22 and thus forms with this a shoulder to which a trained as a federal government screw head of the screw 17' in a later explained in more detail unpressurized operating state of the hydraulic system is struck ,

An dem Schraubenkopf der Stellschraube 17' ist mittels einer axial in diese eingeschraubten Kopfschraube 23 und einer deren Kopf unterlegten Distanzhülse 24 eine zum offenen Ende des Zylinders 22 hin offene Topfmanschette 25 befestigt, die sich an die Innenwandfläche des Zylinders 22 anschmiegt.To the screw head of the adjusting screw 17 'is fixed by means of an axially screwed into this cap screw 23 and a head-mounted spacer sleeve 24 open towards the open end of the cylinder 22 cup cup 25 which conforms to the inner wall surface of the cylinder 22.

Von der Seite des Lagers 7.1 her ist der Lagerschaft 7' mit einer zentralen Sacklochbohrung 26 versehen, welche die die Gewindebuchse 21 aufnehmende Gewindebohrung durchkreuzt.From the side of the bearing 7.1 ago the bearing shaft 7 'is provided with a central blind hole 26, which thwarts the threaded bush 21 receiving threaded bore.

Der Lagerschaft 7' ist zusammengesetzt aus einem Schaftkörper 7'.1 und einer im Expansionsabschnitt 8 angeordneten Druckhülse 7'.2 die im drucklosen Betriebszustand gleitend in die Lagerbohrung (siehe Fig. 2) einsetzbar ist und mit dem Schaftkörper 7'.1 einen Ringraum 7'.3 bildet. Entlang des Ringraumes 7'.3, dessen axiale Erstreckung in etwa mit jener des Expansionsabschnittes 8 zusammenfällt, hat die Druckhülse 7'.2 eine derartige Wandstärke, dass im Falle eines entsprechenden Überdruckes in dem Ringraum 7'.3 die Druckhülse 7'.2 radial expandiert, d. h. der Lagerschaft 7' ist mittels eines entsprechenden Überdruckes in dem Ringraum 7'.3 in der Lagerbohrung 11 (siehe Fig. 2) fixierbar. Insoweit umfasst das Hydrauliksystem im Expansionsschaft 8 einen Ringraum 7'.3 mit einem radial expandierbaren Mantel 7'.4.The bearing shaft 7 'is composed of a shaft body 7'.1 and a pressure sleeve 7'.2 arranged in the expansion section 8, which can be slidably inserted into the bearing bore (see FIG. 2) in the pressureless operating state and forms an annular space with the shaft body 7'.1 7'.3 forms. Along the annular space 7'.3, the axial extent coincides approximately with that of the expansion section 8, the pressure sleeve 7'.2 has a wall thickness such that in the case of a corresponding overpressure in the annular space 7'.3 the pressure sleeve 7'.2 radially expanded, ie the bearing shaft 7 'is by means of a corresponding overpressure in the annular space 7'.3 in the bearing bore 11 (see FIG. 2) can be fixed. In that regard, the hydraulic system in the expansion shaft 8 comprises an annular space 7'.3 with a radially expandable jacket 7'.4.

Die den Mantel 7'.4 ausbildende Druckhülse 7'.2 ist beispielsweise über eine Presspassung mit dem Schaftkörper 7'.1 verbunden.The jacket 7'.4 forming pressure sleeve 7'.2 is connected for example via a press fit with the shaft body 7'.1.

Der Ringraum 7'.3 steht über eine mit diesem kommunizierende erste diametrale Bohrung im Schaftkörper 7'.1 (hier als zur Zeichenebene senkrechte Bohrung dargestellt) in fluidischer Verbindung mit der Sacklochbohrung 26 und über eine mit dem Ringraum 7'.3 kommunizierende zweite diametrale Bohrung im Schaftkörper 7'.1 (hier als in der Zeichenebene verlaufende Bohrung dargestellt) in fluidischer Verbindung mit einer Befüllungsbohrung 27, die von der dem Lager 7.1 abgewandten Seite des Schaftkörpers 7'.1 her in diesen eindringt und mittels einer mit einer Dichtung 28 unterlegten Verschluss-Schraube 29 abgedichtet ist.The annular space 7'.3 is in fluid communication with the blind bore 26 via a first diametrical bore in the shaft body 7'.1 communicating with it (shown here as a vertical bore to the drawing plane) and via a second diametrical communicating with the annular space 7'.3 Bore in the shaft body 7'.1 (shown here as extending in the plane of the bore) in fluid communication with a Befüllungsbohrung 27 which penetrates from the bearing 7.1 side facing away from the shaft body 7'.1 ago in this and by means of a seal 28th undershot closure screw 29 is sealed.

Das Hydrauliksystem umfasst des Weiteren einen Stellkolben 30.1. Dieser ist auf Seiten des Lagers 7.1 in die Sacklochbohrung 26 gleitend eingepasst und an deren Wandung abgedichtet. Der Stellkolben 30.1 trägt an seinem dem Lager 7.1 zugewandten Ende einen Teller 30.2, der zusammen mit dem Stellkolben 30.1 ein Druckstück 30 bildet, welches insbesondere in einem später noch erläuterten gespannten Betriebszustand über den Teller 30.2 an die dem Sicherungsring 7.3 abgewandte Stirnfläche des Außenrings des Lagers 7.1 angestellt ist.The hydraulic system further comprises a control piston 30.1. This is slidably fitted on the side of the bearing 7.1 in the blind hole 26 and sealed at the wall. The adjusting piston 30.1 carries at its end facing the bearing 7.1 a plate 30.2, which forms together with the actuating piston 30.1 a pressure piece 30, which in particular in a later explained tensioned operating state on the plate 30.2 to the locking ring 7.3 facing away from the outer surface of the bearing 7.1 is employed.

Der bereits erläuterte Zylinder 22 kommuniziert über dessen offenes Ende und über einen innen durch die Gewindebuchse 21 und außen durch die diese aufnehmende radiale Gewindebohrung, genauer durch einen in etwa entlang des Zylinders 22 erstreckten Abschnitt der radialen Gewindebohrung begrenzten Ringraum mit der die radiale Gewindebohrung wie bereits erläutert durchkreuzenden Sacklochbohrung 26 und insoweit auch mit dem im Expansionsbereich 8 gelegenen Ringraum 7'.3.The already explained cylinder 22 communicates via its open end and via an inside through the threaded bushing 21 and externally through the latter receiving radial threaded bore, more precisely by an approximately along the cylinder 22 extending portion of the radial threaded bore limited annular space with the radial threaded bore as already explained by crossing blind hole 26 and extent with the located in the expansion region 8 annulus 7'.3.

Die Fig. 3 stellt das insoweit erläuterte Hydrauliksystem in einem bereits genannten und nunmehr nähr erläuterten ungespannten Zustand dar. In diesem Zustand ist der Bund der Stellschraube 17' an die bereits erwähnte Schulter am geschlossenen Ende des Zylinders 22 angelegt und die wie erläutert fluidisch miteinander verbundenen Räume sind mit einer Hydraulikflüssigkeit gefüllt und das Hydrauliksystem ist mittels der Verschluss-Schraube 29 und der Dichtung 28 verschlossen. Damit umfasst der Lagerschaft 7' ein geschlossenes Hydrauliksystem, welches im Expansionsabschnitt 8 einen Ringraum 7'.3 mit einem radial expandierbaren Mantel 7'.4 aufweist, und die Stellschraube 17' erweist sich insofern als Arbeitskolben des Hydrauliksystems als durch deren entsprechende Betätigung - hier Abheben des Bundes der Stellschraube 17' von der genannten Schulter am geschlossenen Ende des Zylinders 22 - die Hydraulikflüssigkeit unter Druck setzbar ist.Fig. 3 illustrates the hydraulic system so far explained in an already mentioned and now nähr explained unstrained state. In this state, the collar of the screw 17 'is applied to the aforementioned shoulder at the closed end of the cylinder 22 and the fluidically interconnected as explained Rooms are filled with a hydraulic fluid and the hydraulic system is closed by means of the closure screw 29 and the seal 28. Thus, the bearing shaft 7 'comprises a closed hydraulic system, which in the expansion section 8 has an annular space 7'.3 with a radially expandable jacket 7'.4, and the screw 17' proves to be working piston of the hydraulic system as by their corresponding operation - here Lifting the collar of the adjusting screw 17 'from said shoulder at the closed end of the cylinder 22 - the hydraulic fluid can be placed under pressure.

Bedingt durch das Verhältnis der Umfangsfläche des Ringraumes 7'.3 zur Querschnittsfläche des Stellkolbens 30.1 und durch eine entsprechend gewählte Federkonstante der Ausgleichsscheibe 7.2 erfolgt bei der Erhöhung des Druckes in der Hydraulikflüssigkeit zunächst die Fixierung des Expansionsschaftes 8 in der Lagerbohrung 11 und anschließend das Herausdrücken des axialen Spieles zwischen einerseits den Lagerhebeln 6 und 6' und andererseits der Messerwelle 2. Dabei wird von einem Zustand ausgegangen, in dem die Messerwelle 2 axial gegen ein Festlager im Lagerhebel 6 abgestützt ist und der Lagerschaft 7' in der Lagerbohrung 11 derart verschoben ist, dass das Lager 7.1 mit seinem Innenring axial an der Messerwelle 2 anliegt.Due to the ratio of the circumferential surface of the annular space 7'.3 to the cross-sectional area of the actuating piston 30.1 and by a correspondingly chosen spring constant of the sheave 7.2 is carried out at the increase of the pressure in the hydraulic fluid, first the fixation of the expansion shaft 8 in the bearing bore 11 and then pushing out the axial play between on the one hand the bearing levers 6 and 6 'and on the other hand, the knife shaft 2. It is assumed that a state in which the blade shaft 2 axially against a fixed bearing in the Bearing lever 6 is supported and the bearing shaft 7 'is displaced in the bearing bore 11 such that the bearing 7.1 rests with its inner ring axially on the blade shaft 2.
