Description

Die Erfindung bezieht sich auf ein Verfahren zum Auskleiden der konkav gewölbten Oberseite der Unterplatte eines Kippbewegungen eines Brückenüberbaus oder dergleichen ermöglichenden Lagers durch Einlegen einer auf ihrer Gleitfläche geschliffenen korrosionsbeständigen Stahlblechscheibe, sowie weiterhin auf ein nach einem solchen Verfahren ausgekleidetes Lager, das eine Oberplatte, eine Unterplatte und eine zwischengeschaltete Zwischenplatte aufweist.The invention relates to a method for lining the concavely curved upper side of the lower plate of a bearing enabling tilting movements of a bridge superstructure or the like by inserting a corrosion-resistant steel plate disk ground on its sliding surface, and furthermore to a bearing lined according to such a method, which has an upper plate, a lower plate and has an intermediate plate.

Bei Kippgleitlagern für Brücken oder andere Bauwerke, bei denen schwere Lasten abgestützt werden müssen, wird herkömmlicherweise die Gleitfläche in der sphärischen Ebene so ausgeführt, daß dort eine Reibkombination PTFE mit Hartchrom vorliegt. Üblicherweise wird hierbei der PTFE-Schicht (Polytetrafluoräthylen-Schicht) in der konkav gewölbten Oberseite des Lagerunterteiles gekammert angebracht, während die gegen diese PTFE-Schicht anlaufende, der konkaven Krümmung der Unterschicht entsprechend konvex angepaßte Krümmung der Unterseite der Zwischenplatte («Kalotte») auf ihrer Oberfläche hartverchromt wird. Es wurde auch bereits die Lösung versucht, die PTFE-Schicht in die konvex gekrümmte Oberfläche der Kalotte einzulegen und die konkav gekrümmte Oberseite des Lagerunterteils mit einer Hartchromschicht zu versehen. Dabei hat sich allerdings gezeigt, daß die Hartverchromung solcher sphärischer, insbesondere konkav ausgeführter Flächen ziemlich teuer ist und die geforderte Gleichmäßigkeit dieser Schicht nur schwierig hergestellt werden kann. Gleichzeitig ist ein ziemlich großer manueller Aufwand für die notwendige Vorpolierung vor dem Verchromungsvorgang und insbesondere auch nach dem Verchromen nicht umgehen. Andererseits ist das Aufbringen einer korrosionsbeständigen Schicht guter Reibeigenschaften jedoch erforderlich.In the case of tilting slide bearings for bridges or other structures in which heavy loads have to be supported, the sliding surface in the spherical plane is conventionally designed in such a way that there is a friction combination of PTFE and hard chrome. Usually, the PTFE layer (polytetrafluoroethylene layer) is attached in a chambered manner in the concavely curved upper side of the lower bearing part, while the curvature of the underside of the intermediate plate («spherical cap»), which runs against this PTFE layer and is convexly adapted to the concave curvature of the lower layer their surface is hard chrome-plated. The solution has also already been attempted to insert the PTFE layer into the convexly curved surface of the spherical cap and to provide the concave curved upper side of the lower bearing part with a hard chrome layer. It has been shown, however, that hard chrome plating of such spherical, in particular concave, surfaces is quite expensive and that the required uniformity of this layer can only be produced with difficulty. At the same time, a fairly large amount of manual effort for the necessary pre-polishing cannot be avoided before the chrome plating process and in particular also after the chrome plating. On the other hand, however, it is necessary to apply a corrosion-resistant layer with good rubbing properties.

Bisher bekannte Zulassungen von Brückenlagern durch das Institut für Bautechnik, Berlin, sehen ausschließlich die Anwendung von PTFE auf der einen Reibseite und das Aufbringen einer Hartchromschicht auf der anderen Reibseite vor. Dies bedeutet, daß bislang die Hartverchromung bei in Deutschland bauaufsichtlich zugelassenen Lagern mit allen sich dabei ergebenden Schwierigkeiten in Kauf genommen werden mußte.Previously known approvals of bridge bearings by the Institut für Bautechnik, Berlin, only provide for the use of PTFE on one friction side and the application of a hard chrome layer on the other friction side. This means that until now hard chrome plating has had to be accepted with all the difficulties that arise in the case of bearings approved by the building authorities in Germany.

In der deutschen Offenlegungsschrift 19 59 964 wird zwar ein Kippgleitlager beschrieben, bei dem zwischen der konkav gewölbten Oberseite seiner Unterplatte und der entsprechend konvex gewölbten Oberfläche des Lager-Zwischenteiles eine bzw. mehrere Schichten aus reibungsverringernden Material angebracht sein sollen. Allerdings wird an keiner Stelle dieser Druckschrift ausgeführt, wie diese reibungsvermindernden Zwischenschichten aufgebracht und wo sie befestigt werden sollen. Weiterhin wird auch nichts über das Auskleiden der konkav gewölbten Oberseite der Unterplatte mit einer korrosionsbeständigen Schutzschicht beschrieben, ganz abgesehen davon, wie so etwas geschehen könnte.German laid-open specification 19 59 964 describes a tilting slide bearing in which one or more layers of friction-reducing material are said to be attached between the concavely curved upper side of its lower plate and the correspondingly convexly curved surface of the intermediate bearing part. However, nowhere in this document is it explained how these friction-reducing intermediate layers are applied and where they are to be attached. Furthermore, nothing is described about lining the concavely curved upper side of the lower plate with a corrosion-resistant protective layer, quite apart from how something like this could happen.

In der deutschen Auslegeschrift 12 61 153 wird ein für Kippbewegungen ausgelegtes Drehgelenk für Baukonstruktionsteile beschrieben bei dem auf die zylindrisch gewölbte untere Drehfläche eine Folie aus elastisch federndem Blech aus Federstahl as Bestandteil einer mehrschichtigen Auflage eingebracht werden kann. Die Auskleidung dieser Drehfläche erfolgt dabei in der Form, daß diese mehrschichtige Auflage mittels einzeiner Niederhaltebügel aus schmalen Blechstreifen bewirkt wird, wobei diese Niederhaltebügel an ihren Enden jeweils befestigt sind und die Niederhaltung der Auflage über ihre zwischen den Befestigungen liegende konvexe Krümmung hinweg bewirken. Die als Niederhaltebügel ausgebildeten Blechstreifen sind dabei über die gesamte Länge der zylindrischen Lagerscheibe hinweg mit relativ großen Zwischenräumen zueinander angeordnet, wodurch sich zwar örtlich eine zufriedenstellende Niederhaltung ergeben kann, das gewünschte gute Anliegen der Auflage über die gesamte Lagerfläche hinweg jedoch nicht sichergestellt ist. Überdies erscheint der Einsatz solcher Niederhalte-Blechstreifen bei zylindrisch geformten Lagerflächen möglich, dürfte jedoch für sphärisch geformte Lagerflächen mit Sicherheit ausscheiden.The German design specification 12 61 153 describes a swivel joint for structural parts designed for tilting movements, in which a film made of resilient spring steel sheet made of spring steel can be introduced as a component of a multilayered support onto the cylindrically curved lower swivel surface. The lining of this rotary surface takes place in such a way that this multilayer support is effected by means of single hold-down brackets made of narrow sheet metal strips, these hold-down brackets being fastened at their ends and causing the support to be held down over their convex curvature lying between the fasteners. The metal strips designed as hold-down brackets are arranged along the entire length of the cylindrical bearing washer with relatively large gaps to one another, which may result in a satisfactory hold-down locally, but the desired good contact of the support over the entire bearing surface is not ensured. In addition, the use of such hold-down sheet metal strips seems possible with cylindrical-shaped bearing surfaces, but should certainly be ruled out for spherically shaped bearing surfaces.

Der schweizer Patentschrift 4 21 167 ist ein Verfahren nach dem Oberbegriff des Patentanspruchs 1 entnehmbar, bei dem bereits die konkav gewölbte Oberseite der Unterplatte durch Einlegen einer auf ihrer Gleitfläche geschliffenen, korrosionsbeständigen Stahlblechscheibe ausgekleidet ist (CH-A-4 21 167, S. 2, Z. 5-8, i. Vbdg. mit Unteranspruch 4). Allerdings ist in dieser Druckschrift nicht beschrieben, wie das Verfahren zum Auskleiden dieses Lagers durch Einlegen der Stahlblechscheibe in die gewölbte Oberseite der Unterplatte im einzelnen durchgeführt werden soll. Allein erwähnt ist nur, daß die Stahlblechscheibe an die gewölbte Oberfläche angegossen, angeschweißt, auf diese aufgelegt oder aufgeplattet sein kann. Die Schwierigkeit, die sich bei Gleitbewegungen unter hoher Last bei mit Auflagen versehenen sphärisch gekrümmten Lagerflächen stellt, nämlich ein möglichst gleichmäßiges und sattes Aufliegen der als Auflage gewählten Stahlblechscheibe über ihren ganzen Umfang hinweg an der sphärisch gekrümmten Auflagefläche, ist in dieser Druckschrift weder angesprochen, noch gar im einzelnen untersucht.The Swiss patent specification 4 21 167 shows a method according to the preamble of claim 1, in which the concavely curved upper side of the lower plate is already lined by inserting a corrosion-resistant steel plate disc that is ground on its sliding surface (CH-A-4 21 167, p. 2 , Lines 5-8, in conjunction with subclaim 4). However, this publication does not describe how the method for lining this bearing is to be carried out in detail by inserting the sheet steel plate into the curved upper side of the lower plate. It is only mentioned that the sheet steel plate can be cast, welded, placed on or flattened onto the curved surface. The difficulty that arises in sliding movements under high load with spherically curved bearing surfaces provided with supports, namely the most uniform and full possible support of the steel plate disc chosen as the support over its entire circumference on the spherically curved support surface is neither addressed in this publication, nor even examined in detail.

Ausgehend hiervon liegt der Erfindung die Aufgabe zugrunde, ein Verfahren nach dem Oberbegriff des Patentanspruches 1 so weiterzu entwickeln, daß das Auskleiden der konkav geformten Oberfläche der Unterplatte rasch und einfach sowie haltbar und materialgerecht ermöglicht und dabei ein besonders festes und sattes Anliegen an der Stahlblechscheibe auf der Unterlage stets sichergestellt wird. Weiterhin liegt der Erfindung die Aufgabe zugrunde, ein nach einem solchen Verfahren ausgekleidetes Lager zu finden, das wirtschaftlich herstellbar und einfach montierbar ist.Based on this, the present invention seeks to develop a method according to the preamble of claim 1 so that the lining of the concave surface of the lower plate allows quick and easy and durable and appropriate to the material and thereby a particularly firm and tight fit on the steel sheet the document is always ensured. Furthermore, the invention has for its object to find a bearing lined by such a method, which is economical to manufacture and easy to assemble.

Die der Erfindung zugrunde liegende Aufgabe wird bei einem Verfahren gemäß dem Oberbegriff des Patentanspruches 1 dadurch gelöst, daß die Stahlblechscheibe vor dem Einlegen auf die Unterplatte mit einer geringen Überformung in ihrem Zentrum vorgewölbt und nach dem Einlegen längs ihres Umfangs gegen die gewölbte Oberseite der Unterplatte angedrückt wird.The object underlying the invention is achieved in a method according to the preamble of claim 1 in that the sheet steel plate bulges with a slight over-molding in its center before insertion onto the lower plate and, after insertion, presses along its circumference against the curved upper side of the lower plate becomes.

Das erfindungsgemäße Verfahren ist einfach und schnell ausführbar, wobei als Befestigung für das Andrücken des Umfangs der Stahlblechscheibe gegen die Oberseite der Unterplatte jede geeignete Befestigungsmöglichkeit vorgesehen werden kann. Neben Verkleben oder Verschweißen wird vorteilhafterweise das Andrücken des Umfangs der Stahlblechscheibe jedoch durch Schrauben und/oder Verspannen vorgenommen. Durch die erfindungsgemäßen Maßnahmen wird innerhalb der Stahlblechscheibe ein Spannungsaufbau erzielt, der ein besonders festes und sattes Anliegen der Stahlblechscheibe auf der Unterlage stets sicherstellt. Weiterhin sind alle Schwierigkeiten, die sich in Verbindung mit dem bisher bekannten und durchgeführten Aufbringen einer Hart-chrom-Oberflächenschicht einstellen, sicher vermieden, wobei gleichzeitig eine erheblich wirtschaftlichere Herstellung möglich ist.The method according to the invention can be carried out simply and quickly, and any suitable fastening option can be provided as a fastening for pressing the circumference of the sheet steel disc against the upper side of the lower plate. In addition to gluing or welding, the pressing of the circumference of the sheet steel plate is advantageously carried out by screwing and / or tensioning. By means of the measures according to the invention, a tension build-up is achieved within the sheet steel plate, which always ensures a particularly firm and tight fit of the sheet steel plate on the base. Furthermore, all difficulties which arise in connection with the previously known and carried out application of a hard chrome surface layer are reliably avoided, and at the same time a considerably more economical production is possible.

Ein nach dem erfindungsgemäßen Verfahren ausgekleidetes Lager weist eine Oberplatte, eine Unterplatte und eine zwischengeschaltete Zwischenplatte auf. Erfindungsgemäß ist hierbei vorgesehen, daß die Stahlblechscheibe an ihrem Umfang von außen her mittels eines an der Unterplatte befestigten Halteringes gegen die Oberseite der Unterplatte verspannt ist, dessen Innenfläche, wiederum vorzugsweise, eine Schräge aufweisen kann, die gegen eine entsprechend ausgebildete Schräge am Außenumfang der Stahlblechscheibe andrückt und dadurch die Scheibe fest auf ihren Sitz aufdrückt. In vorteilhafter Ausgestaltung geht hierbei die Schräge des Halterings oben in einen radial nach innen gerichteten Vorsprung über, gegen den die obere Umfangskante der Stahlblechscheibe anliegt. Hierdurch wird eine kraftund formschlüssige Anpressung der Scheibe gegen ihre Unterlage erreicht, wobei gleichzeitig auch noch ein Zentrierungseffekt ausgenutzt werden kann. Eine weitere, vorteilhafte Ausgestaltung des erfindungsgemäßen Lagers besteht auch darin, daß der Haltering über einen abgerundeten Innenwulst die Stahlblechscheibe von oben her gegen die Unterplatte verspannt. Setzt man für die Befestigung . des Halteringes an der Unterplatte Schrauben ein, dann kann in einfacher Weise durch eine entsprechende Variation der Anzahl der Andruckschrauben eine entsprechend große bzw. variable Andruckkraft gegen die zu verspannende Stahlblechscheibe aufgebracht werden.A bearing lined according to the method according to the invention has an upper plate, a lower plate and an intermediate plate. According to the invention, it is provided here that the steel sheet disc is clamped on its circumference from the outside by means of a retaining ring fastened to the lower plate against the upper side of the lower plate, the inner surface of which, again preferably, can have a bevel which is against a correspondingly designed bevel on the outer circumference of the sheet steel plate presses and thereby presses the pane firmly onto its seat. In an advantageous embodiment, the slope of the retaining ring merges at the top into a radially inward projection, against which the upper peripheral edge of the sheet steel disc bears. In this way, a non-positive and positive pressure of the disc against its base is achieved, and at the same time a centering effect can also be exploited. Another advantageous embodiment of the bearing according to the invention also consists in that the retaining ring braces the sheet steel plate against the lower plate from above via a rounded inner bead. One sets for the attachment. of the retaining ring on the lower plate screws, then a correspondingly large or variable pressing force can be applied in a simple manner by a corresponding variation in the number of pressure screws against the steel plate disk to be clamped.

Vorteilhafterweise besteht die Stahlblechscheibe aus austenitischem Stahlblech einer Dicke von mindestens 0,75 mm und höchstens 5 mm, wobei als austenitisches Stahlblech sich ganz besonders eine Chrom-Nickel-Molybdänlegierung, vorzugsweise etwa eine Legierung der Werkstoffnummer 1 4401 entsprechend DIN 17 440 (Werkstoffbezeichnung : X 5 Cr Ni Mo 18 10), empfiehlt.The steel plate is advantageously made of austenitic steel plate with a thickness of at least 0.75 mm and at most 5 mm, whereby the chromium-nickel-molybdenum alloy is particularly preferred as the austenitic steel plate, preferably an alloy of material number 1 4401 according to DIN 17 440 (material designation: X 5 Cr Ni Mo 18 10), recommended.

Vorteilhafterweise wird bei einem solchen erfindungsgemäßen Lager, bei dem an der der gewölbten Stahlblechscheibe zugewendeten Unterseite der Zwischenplatte ein Werkstoffbelag angebracht ist, dieser zur Verbesserung der Reibverhältnisse in der Kalotten-Reibfläche aus Polytetrafluoräthylen (PTFE) gewählt und an seiner der Stahlblechscheibe zugewendeten Fläche mit schmiermittelgefüllten Schmiertaschen versehen.In such a bearing according to the invention, in which a material covering is attached to the underside of the intermediate plate facing the curved steel sheet disc, this is selected from polytetrafluoroethylene (PTFE) to improve the frictional conditions in the spherical cap friction surface and with lubricant-filled lubrication pockets on its surface facing the steel sheet disc Mistake.

Die Maßnahmen nach der Erfindung ermöglichen eine erhebliche Verkürzung der Durchlaufzeiten in der Fertigung solcher Lager, da wegen der von der sonstigen Lagerherstellung getrennten Vorverformung der Stahlblech-Auflage die Schaffung und Bearbeitung der einzelnen Teile parallel zueinander erfolgen kann. Als weiterer sehr kostengünstiger Faktor kommt hinzu, daß die erfindungsgemäß einzusetzenden vorgeformten gewölbten Auflagen (meist als Teilkugelscheiben ausgeführt) im Handel ohne Schwierigkeiten als Kaufteil bezogen werden können. Die Erfindung besticht durch besondere Einfachheit der Auskleidung, wobei der Einsatz einseitig geschliffener und polierter handelsüblicher Lagerbleche erfolgen kann und eine irgendwie geartete Nachbearbeitung der als Lagerfläche ausgebildeten konkav gewölbten Gleitfläche der Stahlblechscheibe völlig vermieden ist ; denn die handelsüblich erhältlichen Stahlbleche weisen bereits die vorgeschriebenen Oberflächengüte auf. Hierdurch wird nicht nur die besonders schwierige Bearbeitung konkav gekrümmter Gleitflächen, die z. B. bei einer Hartverchromung vorgenommen werden müßte, völlig vermieden, sondern es ist gleichzeitig auch die Durchführung einer formgenauen Verkleidung der Krümmungsfläche bei gleichzeitig formgenauer Einlegung und guter mechanischer Befestigbarkeit innerhalb des zu fordernden Toleranzbereiches gesichert. Erst die Erkenntnis des Zusammenwirkens der verschiedenen erfindungsgemäß beanspruchten Merkmale konnte in zufriedenstellender Weise den erfindungsgemäß angestrebten Erfolg sicherstellen. Die erfindungsgemäßen Lager sind schnell und mit besonders großer Gleichmäßigkeit herstellbar, wobei gleichzeitig die von der ebenen Gleitfläche der Oberplatte aufzunehmenden seitlichen Auslenkungen beim Auftreten einer Verformungsbewegung des Überbaus kleiner als etwa beim gattungsgemäßen Lager sind und gleichfalls auch die Lasteinleitung in das Lager aufgrund des Mittenverschiebungsverhaltens des Schwerpunktes günstiger als beim gattungsgemäßen Kippgleitlager gehalten werden kann.The measures according to the invention enable a considerable reduction in the throughput times in the manufacture of such bearings, since, because of the pre-deformation of the steel sheet support which is separate from the other bearing manufacture, the creation and machining of the individual parts can take place in parallel. Another very inexpensive factor is the fact that the preformed arched supports to be used according to the invention (mostly designed as partial spherical disks) can be obtained commercially without difficulty as a purchased part. The invention is characterized by a special simplicity of the lining, the use of commercially available bearing plates ground and polished on one side and any kind of post-processing of the concave curved sliding surface of the steel plate disk, which is designed as a bearing surface, is completely avoided; because the commercially available steel sheets already have the prescribed surface quality. As a result, not only the particularly difficult machining of concave curved sliding surfaces, the z. B. would have to be made with a hard chrome plating, completely avoided, but it is at the same time the implementation of a form-fitting cladding of the curved surface with simultaneous form-fitting insertion and good mechanical fastenings secured within the tolerance range to be demanded. Only the knowledge of the interaction of the various features claimed according to the invention could satisfactorily ensure the success desired according to the invention. The bearings according to the invention can be produced quickly and with a particularly high degree of uniformity, with the lateral deflections to be absorbed by the flat sliding surface of the top plate being smaller than, for example, in the case of a generic movement of the superstructure, and also the load introduction into the bearing due to the center shift behavior of the center of gravity can be kept cheaper than the generic tilting slide bearing.

The invention is based on the Drawing explained in principle for the sake of example. It shows
  • FIG. 1 shows a schematic side view of a tilt slide bearing according to the invention,
  • FIG. 2 shows an enlarged detailed illustration of detail A from FIG. 1,

Bei dem in Figur 1 dargestellten Kippgleitlager ist eine Oberplatte 1 erkennbar, die auf ihrer Unterseite eben ausgebildet und mit einer gut korrosionsbeständigen Auflageschicht 2 versehen ist. Diese Auflageschicht 2 kann sowohl aus einem nicht rostenden geeigneten Stahlblech, wie auch aus einer Hartchromschicht bestehen.In the tilting slide bearing shown in Figure 1, an upper plate 1 can be seen, which is flat on its underside and is provided with a good corrosion-resistant bearing layer 2. This support layer 2 can consist of a suitable stainless steel sheet as well as a hard chrome layer.

Die Zwischenplatte 4 des Lagers ist an ihrer Oberseite eben und weist dort in gekammerter Aufnahme eine PTFE-Schicht auf, die etwas über die ebene Oberfläche der Zwischenplatte 4 hinaussteht und mit der Auflage 2 an der Oberplatte 1 im (Reib-)Kontakt steht. Die Zwischenplatte 4 ist an ihrer Unterseite sphärisch gewölbt, im dargestellten Ausführungsbeispiel kugelausschnittförmig. In sie ist wiederum in gekammerter Aufnahme eine entsprechend geformte PTFE-Platte 5 eingelassen, die gegen eine nicht rostende Auflage in der entsprechend konkav geformten, oben auf einer Unterplatte 7 angeordneten Krümmungsfläche vorgesehen ist. Diese « Antikorrosionsschicht » ist in Form einer der konkaven Ausgestaltung der Krümmungsfläche der Unterplatte 7 entsprechend vorgewölbten Scheibe 6 ausgeführt, die auf der Unterplatte 7 im dargestellten Beispiel mit einer Klebstoffschicht 10 (Fig. 2) und in ihrem Randbereich zusätzlich über in Bohrungen 12 (Fig. 3) eingelassene Senkkopfschrauben 9 (Fig. 1 bzw. Fig. 2) befestigt ist. Die Unterplatte 7 ihrerseits ist dann auf einem geeigneten Fundament 8 angeordnet, das in Figur 1 nicht näher ausgestaltet ist.The intermediate plate 4 of the bearing is flat on its upper side and there has a PTFE layer in a chambered receptacle, which protrudes slightly beyond the flat surface of the intermediate plate 4 and is in (frictional) contact with the support 2 on the upper plate 1. The intermediate plate 4 is spherically curved on its underside, in the exemplary embodiment shown it is spherical. A suitably shaped PTFE plate 5, which is provided against a non-rusting support in the correspondingly concave shaped curvature surface arranged on top of a lower plate 7, is in turn embedded in it in a chambered receptacle. This “anti-corrosion layer” is designed in the form of a disc 6 that bulges out in accordance with the concave configuration of the curved surface of the lower plate 7, which in the example shown is provided with an adhesive layer 10 (FIG. 2) on the lower plate 7 and additionally in its edge region via holes 12 (FIG 3) recessed countersunk screws 9 (Fig. 1 or Fig. 2) is attached. The lower plate 7 in turn is then arranged on a suitable foundation 8, which is not shown in FIG. 1.

Wie aus Figur 2 ersichtlich ist, ist die gekammerte PTFE-Reibschicht 5 in der gekrümmten Unterfläche der Zwischenplatte 4 auf ihrer der Unterplatte zugewendeten Seite mit schmiermittelgefüllten Schmiertaschen 11 versehen, durch die eine Dauerschmierung der sphärischen Gleitfläche sichergestellt werden kann.As can be seen from Figure 2, the chambered PTFE friction layer 5 is provided in the curved lower surface of the intermediate plate 4 on its side facing the lower plate with lubricant-filled lubrication pockets 11, by means of which permanent lubrication of the spherical sliding surface can be ensured.

Die Oberfläche der vorgeformten Schale 6, d. h. die Seite der Schale 6, die der an der Zwischenplatte unten befestigten PTFE-Schicht zugewendet ist, ist geschliffen und poliert. Die Auskleidung der konkaven Oberfläche der Unterplatte 7 erfolgt dabei folgendermaßen :

  • Zunächst wird die Unterplatte 7 in ihrer genauen Formgebung hergestellt, wobei (ggf. auch gleichzeitig und unabhängig hiervon) aus einem laufenden, handelsüblich erhältlichen, auf der Oberfläche bereits polierten und geschliffenen Metallblech die erforderlichen vorgeformten gewölbten Schalen 6 durch ein geeignetes Verformungsverfahren hergestellt werden. Diese gewölbten Schalen werden sodann in die konkav ausgebildete Krümmungsfläche der Unterplatte 7 eingelegt und dabei dann geeignet miteinander verbunden, z. B. durch eine vorher dort oder auf der Unterseite der Schale aufgetragene Klebstoffschicht, ggf. auch durch im Randbereich der vorgewölbten Schale angeordnete Senkkopfschrauben (welche die alleinigen Befestigungsmittel oder auch zur Klebung zusätzliche Befestigungsmittel darstellen können).
The surface of the preformed shell 6, ie the side of the shell 6 which faces the PTFE layer attached to the intermediate plate at the bottom, is ground and polished. The concave surface of the lower plate 7 is lined as follows:
  • First, the lower plate 7 is produced in its exact shape, the necessary preformed curved shells 6 being produced from a running, commercially available metal sheet that has already been polished and ground on the surface (possibly also simultaneously and independently of this) by means of a suitable shaping process. These curved shells are then placed in the concave curved surface of the lower plate 7 and then suitably connected to each other, for. B. by an adhesive layer previously applied there or on the underside of the shell, if necessary also by countersunk screws arranged in the edge region of the bulging shell (which can be the sole fastening means or also additional fastening means for gluing).

Bei dem in den Figuren gezeigten Kippgleitlager wurde im Interesse einer guten Übersichtlichkeit auf die Darstellung solcher Maßnahmen verzichtet, die bei solchen Kippgleitlagern erforderlich bzw. üblich und jedem Fachmann geläufig sind, etwa seitliche Abdichtungen o. ä.In the case of the tilting slide bearing shown in the figures, in the interest of good clarity, the depiction of measures which are required or customary in such tilting slide bearings and are familiar to any person skilled in the art, such as lateral seals or the like, has been omitted.

Die in Figur 3 gezeigte runde Form für eine Scheibe 6 stellt nur eine Ausführungsmöglichkeit einer solchen Scheibe dar. Prinzipiell ist die Verwendung jeder geeigneten, auch nicht-runden Form für die Scheibe 6 möglich, so insbesondere auch etwa eine Vieleckform (z. B. achteckig), wobei die Seiten jeweils die Tangente des inneren Nutzungsdurchmessers der Scheibe 6 darstellen.The round shape shown in FIG. 3 for a disk 6 represents only one possible embodiment of such a disk. In principle, it is possible to use any suitable, even non-round shape for the disk 6, in particular also a polygonal shape (e.g. octagonal) ), the sides each representing the tangent of the inner use diameter of the disk 6.

In den Figur 4 bis 6 sind (im Prinzip) verschiedene Möglichkeiten für ein mechanisches Niederspannen der Scheibe 6 gegen ihre Auflagefläche durch Einsatz eines Halteringes 13 gezeigt, der über Schrauben 9' gegen die Unterplatte 7 angeschraubt werden kann. Dieses rein mechanische Einspannen der Scheibe 6 setzt ein Verkleben der Scheibe 6 gegen die Unterlage 7 nicht mehr voraus, weshalb hier die Gefahr der Unterrostung bestehen kann. Aus diesem Grunde ist (zumindest) im Bereich der Auflagefläche der Unterplatte 7 für die Scheibe 6 eine korrosionsverhindernde Schicht 17 auf die Unterplatte 7 aufgebracht. Diese Korrosions-Schutzschicht 17 ist dabei als zweifache Auftragung des sogenannten « Grundanstriches » ausgeführt, der in einem Bereich von ca. 50 I-Lm Schichtdicke liegt.4 to 6 show (in principle) various possibilities for mechanically lowering the disk 6 against its support surface by using a retaining ring 13 which can be screwed against the lower plate 7 by means of screws 9 '. This purely mechanical clamping of the pane 6 no longer requires the pane 6 to be glued to the base 7, which is why there may be a risk of under-rusting here. For this reason, a corrosion-preventing layer 17 is applied to the base plate 7 (at least) in the area of the support surface of the base plate 7 for the disc 6. This corrosion protection layer 17 is carried out as a double application of the so-called “base coat”, which is in a range of approximately 50 I-Lm layer thickness.

Bei dem Ausführungsbeispiel von Figur 4 ist der Haltering 13, der über Schrauben 9' auf der Unterplatte 7 festgespannt ist, mit einer auf seiner Innenseite unten liegenden Schräge 14 versehen, die gegen eine entsprechende Schräge am Ende der Schicht 6 anliegt. Wird der Haltering 13 über die Schrauben 9' nun gegen die Unterplatte 7 angespannt, dann wird infolge der Keilwirkung zwischen den Schrägen des Halteringes 13 und der Schale 6 eine zunehmende Verspannung der Schale 6 gegen die Unterplatte 7 erreicht, bis eine völlige Anpassung an die Unterlage und ein absolut fester Sitz vorliegt.In the embodiment of Figure 4, the retaining ring 13, which is clamped by screws 9 'on the lower plate 7, is provided with a bevel 14 on the inside at the bottom, which bears against a corresponding bevel at the end of the layer 6. If the retaining ring 13 is now tightened against the lower plate 7 by means of the screws 9 ', then, due to the wedge action between the bevels of the retaining ring 13 and the shell 6, the shell 6 is increasingly braced against the lower plate 7 until a complete adaptation to the base and there is an absolutely tight fit.

Der Haltering 13 bei dem Ausführungsbeispiel nach Figur 5 weist wiederum unten an seiner Innenseite eine Schräge 14 auf, die jedoch diesmal nicht (wie bei dem Ausführungsbeispiel nach Fig. 4) erheblich länger als die Schräge der vorgewölbten Scheibe 6 ausgeführt ist ; vielmehr geht hier die Schräge 14 unmittelbar an der oberen Außenkante der gewölbten Scheibe 6 in einen radial nach innen vorspringenden Absatz 15 des Halteringes 13 über, so daß beim Anschrauben des Halteringes 13 an die Unterplatte 7 zum einen die Keilwirkung über die Schräge 14 (ähnlich wie im Beispiel nach Fig. 4) ausgeübt wird, gleichzeitig jedoch durch den zwischen der Schräge 14 und dem Vorsprung 15 ausgebildeten Winkel ein Ausweichen der Scheibe 6 nach oben durch Anliegen an den Vorsprung 15 verhindert und dadurch zusätzlich ein Niederdrücken des Endes der Scheibe 6 auf die Anlage dort erzielt wird.The retaining ring 13 in the exemplary embodiment according to FIG. 5 in turn has a bevel 14 on the inside on the inside, which, however, this time is not (as in the exemplary embodiment according to FIG. 4) significantly longer than the bevel of the bulging disk 6; rather, here the slope 14 goes directly on the upper outer edge of the curved disc 6 into a radially inwardly projecting shoulder 15 of the retaining ring 13, so that when the retaining ring 13 is screwed onto the lower plate 7, on the one hand the wedge effect is exerted over the slope 14 (similar to the example according to FIG. 4), but at the same time due to that between the slope 14 and the projection 15 trained angle prevents a deflection of the disc 6 upwards by abutting the projection 15 and thereby additionally pressing the end of the disc 6 onto the system is achieved there.

Auch bei dem Ausführungsbeispiel, das in Figur 6 gezeigt ist, wird im Endbereich der vorgewölbten Scheibe 6 ein Niederdrücken derselben durch einen abgerundeten unteren Innenwulst 16 des Halteringes 13 erzwungen.In the exemplary embodiment shown in FIG. 6, in the end region of the bulging disk 6, the same is forced down by a rounded lower inner bead 16 of the retaining ring 13.

Die vorgewölbte Scheibe 6 ist bei den dargestellten Ausführungsbeispielen vor ihrem Aufbringen auf die Unterplatte 7 derart vorgeformt, daß in ihrem Zentrum eine leichte Überformung ausgebildet ist (d. h., der Krümmungsradius ist dort etwas kleiner als der entsprechende Krümmungsradius auf der Unterplatte 7). Wird die solchermaßen vorgeformte gewölbte Scheibe 6 dann auf die Unterplatte 7 aufgelegt, dann steht der Endbereich der Platte 6 etwas von der zugehörigen Auflagefläche ab. Dieses Abstehen wird sodann durch mechanisches Anpressen über den Haltering 13 wieder abgebaut, was nicht nur zu einem Anliegen auch des Endbereiches der Scheibe 6 an die Aufnahmefläche auf der Unterplatte 7 führt, sondern gleichzeitig auch noch einen Spannungsaufbau innerhalb der Platte 6 derart ausbildet, daß ein besonders festes und sattes Anliegen der Scheibe 6 auf der Unterlage 7 sichergestellt ist.The bulging disc 6 is preformed in the illustrated embodiments before it is applied to the base plate 7 such that a slight overmolding is formed in its center (i.e. the radius of curvature there is somewhat smaller than the corresponding radius of curvature on the base plate 7). If the arched disc 6 preformed in this way is then placed on the lower plate 7, the end region of the plate 6 protrudes somewhat from the associated contact surface. This protrusion is then broken down again by mechanical pressing via the retaining ring 13, which not only leads to the end region of the disk 6 also resting against the receiving surface on the lower plate 7, but at the same time also builds up tension within the plate 6 in such a way that a particularly firm and full contact of the disc 6 on the base 7 is ensured.
