WALZENLAGERUNG MIT EINEM ÜBER EINSTELLRINGE VERBUNDENEN HALTERING, DER AUS EINEM BAJONETTRING BESTEHTROLLER BEARING WITH A HOLDING RING CONNECTED BY ADJUSTING RINGS AND CONSISTING OF A BAYONET RING
Beschreibungdescription
Die Erfindung betrifft eine Walzenlagerung mit Einbaustücken, in denen eine sich entlang der Waizeπachse erstreckende Walze zum Walzen eines Metallbandes mit dem Walzenzapfen gelagert ist, wobei jedes Einbaustück mit dem Walzenzapfen über einen Haltering und Einstellriπge verbunden ist.The invention relates to a roller bearing with chocks, in which a roll extending along the Waizeπachse is mounted for rolling a metal strip with the roll neck, wherein each chock is connected to the roll pin via a retaining ring and adjusting rings.
Die Abnutzung der Walzen im laufenden Betrieb macht es notwendig, die Walzen nachzuschleifen, un zwar sowohl die Arbeits- wie auch die Zwischenwalzen. Um dies durchführen zu können, müssen die Einbaustücke von den Walzen abgezogen werden.The wear of the rolls during operation makes it necessary to regrind the rolls, both the work rolls and the intermediate rolls. In order to do this, the chocks must be removed from the rollers.
Hierzu werden normalerweise die vorhandenen Einsteilringe gelöst, geteilte Halteringe demontiert und erst dann können die Einbaustücke von den Walzen axial abgezogen werden. Die Halteringe und Einstellringe werden bei diesem Verfahren beiseite gelegt, so dass es nicht auszuschließen ist, dass im üblicherweise rauen Hüttenbetrieb Teile auch verloren gehen oder verlegt werden können. Benötigt werden diese aber natürlich dann, wenn - in umgekehrter Reihenfolge - wieder der Zusammenbau erfolgt.For this purpose, the existing part rings are normally loosened, split retaining rings are dismantled and only then can the chocks be axially removed from the rollers. With this procedure, the retaining rings and setting rings are set aside so that it cannot be ruled out that parts can also get lost or be misplaced in the usually rough metallurgical operation. However, these are of course required if - in reverse order - the assembly takes place again.
Aufgabe der Erfindung ist es daher, eine Walzenlagerung zu schaffen, die eine wesentlich vereinfachte Montage bzw. Demontage der Walzen erlaubt.The object of the invention is therefore to provide a roller bearing that allows a significantly simplified assembly and disassembly of the rollers.
Gelöst wird diese Aufgabe erfindungsgemäß dadurch, dass der Haltering aus einem Bajonettring besteht, der sich im die Walze gegenüber dem Einbaustück arretierenden Zustand an dem Walzenzapfen abstützt und der gegenüber diesem verdrehbar gelagert ist, um von dem arretierenden Zustand in einen Demontagezustand zu gelangen, in dem das Einbaustück von dem Walzenzapfen axial abziehbar ist.This object is achieved according to the invention in that the retaining ring consists of a bayonet ring which is supported on the roll neck in the state in which the roller locks against the chock and which is rotatably mounted relative to the latter in order to move from the locked state to a disassembly state in which the chock is axially removable from the roll neck.
Der Bajonettring stützt sich an dem Walzeπzapfen, an auf diesem vorgesehenen Nocken, ab. Die Einstellringe bestehen in üblicher Weise aus zwei axial hintereinander angeordneten Ringen, die über ein Innen- bzw. Außengewinde so miteinander verbunden sind, dass der axiale Abstand voneinander veränderbar ist, so dass auf diese Weise das axiale Spiel der Lager einstellbar ist.The bayonet ring is supported on the roll pin, on cams provided on it. The adjusting rings consist in the usual way of two rings arranged axially one behind the other, which are connected to one another via an internal or external thread in such a way that the axial distance from one another can be changed, so that the axial play of the bearings can be adjusted in this way.
Zur Sicherung der Einstellung wird stirnseitig eine Passfeder in eine vorgesehene Nut an den Einstellringen eingebracht.To secure the setting, a feather key is inserted into a groove provided on the setting rings.
Der Bajonettring ist über koaxial zur Walzenachse angeordnete Schrauben mit dem einen Einstellring verdrehfest verbindbar, wobei am Bajonettring Langlöcher vorgesehen sind, in denen am Einstellring vorgesehenen Schrauben geführt sind, so dass der Bajonettring über den durch die Langlöcher vorgegebenen Winkel gegenüber dem entsprechenden Einstellring verdrehbar ist.The bayonet ring can be connected non-rotatably to the one setting ring via screws arranged coaxially to the roller axis, elongated holes being provided in the bayonet ring, in which screws provided on the setting ring are guided, so that the bayonet ring can be rotated relative to the corresponding setting ring by the angle predetermined by the elongated holes.
Nach einer weiteren Ausbildung der Erfindung ist am Einbaustück ein sich über den halben Kreisumfang erstreckender Sicherungsring vorgesehen, um sowohl den Bajonettring wie auch die Einsteilringe beim Abziehen des Einbaustückes von dem Walzenzapfen an diesem zu halten.According to a further embodiment of the invention, a circlip extending over half the circumference is provided on the chock to hold both the bayonet ring and the parting rings when the chock is removed from the roll neck.
Die Erfindung soll nachfolgend anhand der Zeichnung erläutert werden.The invention will be explained below with reference to the drawing.
Dabei zeigt:It shows:
Figur 1 einen Teiliängsschnitt durch das Einbaustück mit Walzenzapfen und Walze,FIG. 1 shows a partial longitudinal section through the chock with roll neck and roll,
Figur 2 eine Vorderansicht auf das Einbaustück undFigure 2 is a front view of the chock and
Figur 3 eine Vorderansicht und einen Schnitt durch den Bajonettring.Figure 3 is a front view and a section through the bayonet ring.
Nachfolgend sollen nur die in Zusammenhang mit der Erfindung wesentlichen Teile erläutert werden.Only the parts essential in connection with the invention are to be explained below.
Auf die Walze 1 ist ein Einbaustück 2 aufgeschoben, wobei in der Zeichnung nur die eine Seite der Walzenlagerung dargestellt ist, d.h. die gegenüberliegende Seite der Walze ist entsprechend gelagert.A chock 2 is pushed onto the roller 1, only one side of the roller bearing being shown in the drawing, i.e. the opposite side of the roller is supported accordingly.
Auf dem in Verlängerung der Walze vorgesehenen Walzenzapfen 9 sind Nocken oder ggf. Einschnitte 3 vorgesehen, die mit dem Bajonettring 4 zusammenwirken. Je nach Verdrehung des Bajonettringes, relativ zu diesen Nocken 3, kommen die Nocken 3 mit den. Nocken am Bajonettring in Eingriff miteinander oder ermöglichen ein axiales Verschieben des Bajonettringes in Richtung Walzeπzapfenende bzw. Walzenmitte. Im Bajonettring sind stirnseitig Langiöcher 5 vorgesehen, die Schrauben 8 aufnehmen, mittels der der Bajonettring einerseits gegenüber dem Einstellring 6, der die Schrauben aufnimmt, verdrehbar ist und andererseits gleichzeitig von diesem gehalten wird.On the roll neck 9 provided as an extension of the roll, cams or, if necessary, incisions 3 are provided which cooperate with the bayonet ring 4. Depending on Rotation of the bayonet ring, relative to these cams 3, the cams 3 come with. Cams on the bayonet ring are in engagement with one another or enable the bayonet ring to be axially displaced in the direction of the roll pin end or roll center. In the bayonet ring, oblong holes 5 are provided on the end face, which receive screws 8, by means of which the bayonet ring can be rotated on the one hand relative to the setting ring 6, which receives the screws, and on the other hand is held by the latter.
Normalerweise würden der Bajonettring und die Einstellringe beim Abziehen des Einbaustückes von der Walze bzw. dem Walzenzapfen abfallen und üssten dann gesondert aufbewahrt werden.Normally, the bayonet ring and the adjusting rings would fall off when the chock was removed from the roller or the roll neck and would then have to be kept separately.
In Ausgestaltung der Erfindung ist nun aber ein Sicherungsring 7 vorgesehen, der den unteren Bereich des Einstellringes halbkreisförmig umgibt und mit dem Einbaustück fest verbunden ist. Dieser Sicherungsring ist nun so gestaltet, dass er beim Abziehen des Einbaustückes sowohl die Einstellringe wie auch den Bajonettring am Einbaustück unverlierbar hält.In an embodiment of the invention, however, a locking ring 7 is now provided, which surrounds the lower region of the adjusting ring in a semicircular shape and is firmly connected to the chock. This circlip is now designed so that when the chock is removed, both the setting rings and the bayonet ring on the chock are retained.
Die erfindungsgemäße Konstruktion der Walzenlagerung hat den Vorteil, dass Einstellarbeiten nur einmalig durchzuführen sind bzw. nur nach erfolgtem Lagerwechsel.The construction of the roller bearing according to the invention has the advantage that adjustment work can only be carried out once or only after the bearing has been changed.
Mit diesen einmalig durchzuführenden Einstellarbeiten werden die allgemeinen Bauteiltoleranzen sowie die Breitentoleranzen des eingebauten Lagers ausgeglichen. With this one-off adjustment work, the general component tolerances and the width tolerances of the installed bearing are compensated.
