Abstract

The device has reinforcing elements 12 to 15. During the operation of such a sealing device, it has been found that zone 26 of the sealing device tends to bend at high speeds of revolution. At the same time, the annular rib 18 and the annular lip 20 are pressed against the sealing surface 21. This results in high wear and premature failure. It is proposed to vulcanise a reinforcing element 24, 25 into zone 26 of the seal body. <IMAGE>

Description

Die Erfindung betrifft eine Dichtungsvorrichtung für Walzen­lager in Walzgerüsten, bei denen der Walzenzapfen einen konischen Abschnitt zwischen der Walzenstirnfläche und dem mit einer Zapfenbuchse bestückten, in einer Lagerbuchse im Lagergehäuse gelagerten Bereich des Walzenzapfens aufweist, mit einem einstückigen, ringförmigen, flexiblen und mittels Drahtseil und ggf. eines Drahtbandes mittig stabilisierten Dichtungskörper, der auf den konischen Abschnitt aufgescho­ben ist und mit Ringdichtungsansätzen an diesem anliegt, wobei der zapfenbuchsenseitige Ringdichtungsansatz mittels einer Schraubenfeder stabilisiert ist und der Dichtungskör­per mit dem äußeren Ringende mindestens einer von zwei in axialem Abstand angeordneten radialen, elastischen Ringrip­pen mit elastischem Reibungskontakt an mindestens eine ge­häusefeste bzw. deckelfeste , seitlich eines Ringbundes angeordnete ringförmige Dichtfläche anlegbar ist.The invention relates to a sealing device for roller bearings in roll stands, in which the roll neck has a conical section between the end face of the roll and the area of the roll neck equipped with a journal bushing, which is mounted in a bearing bush in the bearing housing, with a one-piece, ring-shaped, flexible and by means of wire rope and if necessary a wire band stabilized sealing body, which is pushed onto the conical section and rests with ring sealing lugs on the latter, the ring sealing lug on the journal bushing side being stabilized by means of a helical spring and the sealing body with the outer ring end having at least one of two radial, elastic ring ribs arranged at an axial distance elastic frictional contact can be applied to at least one housing-fixed or cover-fixed annular sealing surface arranged on the side of an annular collar.

Eine derartige Dichtungsvorrichtung ist durch die DE-OS 36 01 238 bekanntgeworden. Bei der bekannten Dich­tungsvorrichtung wird der Bereich zwischen den beiden Ring­rippen von einem Stahlband umgeben. Das Stahlband wirkt den Zentrifugalkräften entgegen und hält den Dichtungskörper in Form. Damit der Dichtungskörper in sich stabil bleibt ist in dessen mittleren Bereich ein Drahtseil-Ring und eine, diesen umgebende Schraubenfeder vorgesehen. Der zapfenbuchsenseiti­ge Ringdichtungsansatz ist mit einer Schraubenfeder verse­hen, um entgegen der Zentrifugalkraft einen sicheren Sitz des Ringdichtungsansatzes am Walzenzapfen zu gewährleisten.Such a sealing device has become known from DE-OS 36 01 238. In the known sealing device, the area between the two ring ribs is surrounded by a steel band. The steel band counteracts the centrifugal forces and keeps the sealing body in shape. So that the sealing body remains stable in itself the middle area of which is provided with a wire rope ring and a coil spring surrounding it. The ring seal shoulder on the journal sleeve side is provided with a helical spring in order to ensure that the ring seal shoulder sits securely against the roll neck against the centrifugal force.

Im Betrieb einer derartigen Dichtungsvorrichtung hat es sich gezeigt, daß die zapfenbuchsenseitige Ringrippe stärker an die Dichtfläche angepreßt wird als die walzenseitige Ring­rippe und dadurch stärker verschleißt. Sehr hohe Umdrehungs­geschwindigkeiten und damit sehr hohe Anpreßkräfte können dazu führen, daß die Spitze der an der Dichtungsrippe ange­ordneten Dichtungslippe entgegen der Zentrifugalkraft von der Dichtfläche fort auf den Walzenzapfen zu gebogen wird. Bei dieser sogenannten Schuhbildung der Dichtungslippe ist deren Dichtungsfunktion stark eingeschränkt. Hinzu kommt, daß die Dichtungsrippe bei hohen Umdrehungsgeschwindigkeiten nicht mehr parallel zum mit dem Lagergehäuse fest verbunde­nen Ringbund ausgerichtet ist und es bei axialer Verschie­bung der Walze und damit der Dichtungsvorrichtung zu einem Kontakt zwischen der sich drehenden Dichtungsrippe und dem feststehenden Ringbund kommen kann. Diese Berührung führt in der Regel zu einer schnellen Zerstörung der Dichtungsrippe.In the operation of such a sealing device, it has been shown that the ring rib on the journal sleeve side is pressed more strongly against the sealing surface than the ring rib on the roller side and thereby wears out more. Very high rotational speeds and thus very high contact forces can lead to the tip of the sealing lip arranged on the sealing rib being bent away from the sealing surface against the centrifugal force on the roll neck. With this so-called shoe formation of the sealing lip, its sealing function is severely restricted. In addition, the sealing rib is no longer aligned at high rotational speeds parallel to the ring collar fixedly connected to the bearing housing, and contact between the rotating sealing rib and the fixed ring collar can occur when the roller and thus the sealing device are axially displaced. This contact usually leads to a rapid destruction of the sealing rib.

Der Erfindung liegt die Aufgabe zugrunde, eine gattungsge­mäße Dichtungsvorrichtung dahingehend zu verbessern, daß auch bei hohen Umdrehungsgeschwindigkeiten eine gleichblei­bend gute Dichtwirkung und ein niedriger Verschleiß der Dichtungselemente gewährleistet wird.The invention has for its object to improve a generic sealing device in such a way that a consistently good sealing effect and low wear of the sealing elements is ensured even at high rotational speeds.

Diese Aufgabe wird dadurch gelöst, daß der die zapfenbuch­senseitige Ringrippe einstückig halternde Dichtungskörperbe­reich durch ein Drahtseil-Ring bewehrt ist. Der Drahtring bewirkt, daß sich dieser Bereich des Dichtungskörpers und die damit einstückig verbundene Ringrippe nicht der Zentri­fugalkraft folgende nach außen auf die Dichtungsfläche zube­wegen kann. Gleichzeitig wird verhindert, daß sich dieser Bereich um den einstückig ausgebildeten Verbindungssteg zum Dichtungskörper biegen kann, so daß die Dichtungsrippe stets parallel zum feststehenden Ringbund des Lagergehäuses ausge­richtet ist.This object is achieved in that the sealing body region holding the ring rib on the journal bushing in one piece is reinforced by a wire rope ring. The wire ring has the effect that this area of the sealing body and the ring rib connected in one piece with it cannot move outwards following the centrifugal force onto the sealing surface. At the same time, this area is prevented from being able to bend around the integrally formed connecting web to the sealing body, so that the sealing rib is always aligned parallel to the fixed annular collar of the bearing housing.

Von Vorteil ist, wenn der Drahtseil-Ring in den Dichtungs­körper einvulkanisiert ist.It is advantageous if the wire rope ring is vulcanized into the sealing body.

Ist um den Drahtseil-Ring eine Schraubenfeder in den Dich­tungskörper einvulkanisiert, so kann der Drahtseil-Ring sicher in einer bestimmten Position gehalten werden.If a helical spring is vulcanized into the sealing body around the wire rope ring, the wire rope ring can be held securely in a certain position.

Wird der Drahtring im zapfenbuchsenseitigen Endbereich des Dichtungskörpers vorgesehen, so ist sichergestellt, daß alle Bereiche des Dichtungskörpers aureichend bewehrt sind, so daß keine Verformung und Verbiegung am elastischen Dich­tungskörper auftreten können.If the wire ring is provided in the end region of the sealing body on the journal sleeve side, it is ensured that all areas of the sealing body are adequately reinforced, so that no deformation and bending can occur on the elastic sealing body.

Ein Ausführungsbeispiel der Erfindung wird anhand von Fig. 1 näher erläutert.
Figur 1 der Zeichnung zeigt einen Dichtungskörper 1, wie er bei beliebig hohen Drehzahlen Einsatz finden kann. Der Dich­tungskörper 1 ist auf den konischen Absatz 2 eines Walzen­zapfens 3 aufgeschoben. Der Walzenzapfen 3 der Walze 4 sitzt in einer Zapfenbuchse 5, die sich mit dem Walzenzapfen 3 dreht. Die Lagerbuchse 5 lagert in einer Lagerbuchse 6 des feststehenden Lagergehäuses 7. Dem Spalt zwischen der Zapfen buchse 5 und der Lagerbuchse 6 wird ständig Öl zugeführt. Eine Auffangrinne 8 des Lagergehäuses 7 bildet einen Öl­sumpf. Über eine Abflußbohrung 9 fließt das Öl zur Wieder­aufbereitung ab.An embodiment of the invention is explained in more detail with reference to FIG. 1.
Figure 1 of the drawing shows a sealing body 1, as it can be used at arbitrarily high speeds. The sealing body 1 is pushed onto the conical shoulder 2 of a roll neck 3. The roll neck 3 of the roll 4 is seated in a pin bush 5 which is in contact with the roll neck 3 turns. The bearing bush 5 is mounted in a bearing bush 6 of the fixed bearing housing 7. The gap between the journal bush 5 and the bearing bush 6 is constantly supplied with oil. A gutter 8 of the bearing housing 7 forms an oil sump. The oil flows out for reprocessing via a drain hole 9.

Der Dichtungskörper 1 soll das aus dem Lagerspalt austreten­de Öl daran hindern, auf die Walze zu gelangen. In Fällen in denen das Walzgut bzw. die Walze mit Kühlmittel beaufschlagt wird, soll der Dichtungskörper zusätzlich ein Vermischen des Öls mit der Kühlflüssigkeit verhindern.The sealing body 1 is intended to prevent the oil emerging from the bearing gap from reaching the roller. In cases in which coolant is applied to the rolling stock or the roll, the sealing body is also intended to prevent the oil from mixing with the cooling liquid.

Der Dichtungskörper weist zwei Ringdichtungsansätze 10, 11 auf, um sowohl auf der Öl- als auf der Kühlmittelseite dicht mit dem Ansatz 2 des Walzenzapfen 3 abzuschließen. Dem Ring­dichtungsansatz 10 ist eine Schraubenfeder 12 zugeordnet, um einen sicheren Andruck an den Ansatz 2 zu gewährleisten.The sealing body has two ring sealing lugs 10, 11 in order to seal tightly with the lug 2 of the roll neck 3 both on the oil side and on the coolant side. A helical spring 12 is assigned to the ring seal attachment 10 in order to ensure a secure pressure on the attachment 2.

Eine Kombination aus einer Schraubenfeder 13 und einem Drahtseil-Ring 14 dient zur Bewehrung des Dichtungskörpers 1. Die zylindrische äußere Umfangsfläche des Dichtungskör­pers 1 wird von einem Stahlband 15 als Verstärkungselement umschlossen. Ein ringförmiges Dichtungselement 16 kann bei Naßbetrieb zum Einsatz gelangen.A combination of a coil spring 13 and a wire rope ring 14 serves to reinforce the sealing body 1. The cylindrical outer peripheral surface of the sealing body 1 is enclosed by a steel band 15 as a reinforcing element. An annular sealing element 16 can be used in wet operation.

Am Dichtungskörper 1 sind Ringrippen 17, 18 einstückig ange­formt. Die Spitzen der Ringrippen 17, 18 gehen in Ringlippen 19, 20 über. Die Ringlippen 19, 20 laufen auf feststehenden Dichtflächen 21, die mit dem Deckel 27 des Lagergehäuse 7 fest verbunden sind. Ebenfalls mit dem Deckel 27 fest ver­bunden ist ein Ringbund 22 der zwischen den Ringrippen 17, 18 angeordnet ist und auf den Dichtungskörper 1 weist. Die Ringrippen 17, 18 mit ihren Ringlippen 19, 20 und der Ring­bund 22 bilden ein Labyrinth, in dem sich Öl bzw. Kühlmit­telpartikel fangen können, die die Ringlippen passiert ha­ben. Am Dichtungskörper 1 ist eine Öl-Abweisnase 23 vorgese­hen, die das aus dem Lagerspalt austretende Öl in den Öl­sumpf leiten soll.Ring ribs 17, 18 are integrally formed on the sealing body 1. The tips of the ring ribs 17, 18 merge into ring lips 19, 20. The annular lips 19, 20 run on fixed sealing surfaces 21 which are firmly connected to the cover 27 of the bearing housing 7. An annular collar 22, which is between the annular ribs 17, 18 is arranged and points to the sealing body 1. The ring ribs 17, 18 with their ring lips 19, 20 and the ring collar 22 form a labyrinth in which oil or coolant particles that have passed the ring lips can catch. An oil-deflecting lug 23 is provided on the sealing body 1 and is intended to guide the oil emerging from the bearing gap into the oil sump.

Ein von einer Schraubendfeder 24 umgebender Drahtseil-Ring 25 ist in den Dichtungskörper 1 einvulkanisiert. Auch dieser Drahtseil-Ring 25 mit seiner Schraubenfeder 24 dient zur Bewehrung des Dichtungskörpers 1. Dabei ist der Drahtseil­Ring 25 so angeordnet, daß der die Dichtungsrippe 18 und die Öl-Abweisnase 23 aufweisende, eine verhältnismäßig große Masse besitzende Bereich 26 des Dichtungskörpers 1 auch bei großen Umdrehungsgeschwindigkeiten formstabil bleibt.A wire rope ring 25 surrounded by a helical spring 24 is vulcanized into the sealing body 1. This wire rope ring 25 with its helical spring 24 also serves to reinforce the sealing body 1. The wire rope ring 25 is arranged in such a way that the area 26 of the sealing body 1, which has the sealing rib 18 and the oil-repelling nose 23, has a relatively large mass remains stable at high speeds.

Figur 2 zeigte dagegen das Verhalten eines bekannten Dich­tungskörpers 1 bei hohen Umdrehungsgeschwindigkeiten. Die Fliegkraft bewirkt bei der großen Masse des Bereichs 26 daß dieser, bewegt durch stark nach außen gebogen wird.FIG. 2, on the other hand, showed the behavior of a known sealing body 1 at high speeds of rotation. With the large mass of the region 26, the flying force causes it to be moved by being strongly bent outwards.

Dadurch ist die Ringrippe 18 nicht mehr parallel zum Ring­bund 22 ausgerichtet und kann schon bei kleinen axialen Verschiebungen der Walze und damit des Dichtungskörpers 1 am Ringbund 22 schleifen, wodurch die Ringrippe 18 zerstört wird.As a result, the annular rib 18 is no longer aligned parallel to the annular collar 22 and can grind on the annular collar 22 even with small axial displacements of the roller and thus of the sealing body 1, as a result of which the annular rib 18 is destroyed.

Der Druck auf die Ringlippe 20 ist so stark, daß sich deren Spitze zurück, auf den Dichtungskörper 1 zubiegt. Dabei ist die Dichtungslippe 20 einem sehr starken Verschleiß unter­worfen. Ein einwandfreies Abdichten ist in dieser Lage der Ringlippe 20 nicht mehr möglich, so daß sehr viel Öl in das Labyrinth gelangen kann. Hier vermischt es sich entweder mit dem Kühlmittel und kann anschließend nicht mehr verwendet werden oder es gelangt sogar bis zum Walzgut, wo es eine Qualitätsminderung des Walzgutes bewirkt.The pressure on the annular lip 20 is so strong that its tip bends back onto the sealing body 1. The sealing lip 20 is subjected to very heavy wear. In this position, perfect sealing is essential Ring lip 20 no longer possible, so that a lot of oil can get into the labyrinth. Here it either mixes with the coolant and can then no longer be used, or it even reaches the rolling stock, where it reduces the quality of the rolling stock.

Weiteren Schaden kann der Dichtungskörper dadurch nehmen, daß die Öl-Abweisnase 23 auf der Dichtfläche 21 schleift und dabei zerstört wird.The sealing body can be further damaged in that the oil-repelling nose 23 rubs on the sealing surface 21 and is destroyed in the process.
