Rolle für Brückenlager od. dgl.Roller for bridge bearings or the like.

Die Neuerung betrifft eine Rolle, die z. B. bei Brückenlagern zwischen zwei Gleitplatten angeordnet wird und die dazu dient, die Bewegungen der Brücke auf das Brückenfundament auszugleichen.The innovation relates to a role that z. B. is arranged between two sliding plates in bridge bearings and is used to to compensate for the movements of the bridge on the bridge foundation.

Es ist bekannt, derartige Rollen aus hochwertigen Sonderstählen zu fertigen, um die hohen Drücke aufnehmen zu können. Auch ist es bekannt, derartige Rollen mit einer Chromschicht zu versehen, um den Rollwiderstand zu verringern.It is known to manufacture rollers of this type from high-quality special steels in order to be able to absorb the high pressures. Also is it is known to provide such rollers with a chrome layer in order to reduce the rolling resistance.

Bei derartigen mit einer Hartchromschicht versehenen Rollen hat es sich gezeigt, dass die Chromschicht an den kanten der Stirnflächen dicker wird als auf der Mantelfläche der Rolle» Diese Verdickungen oder Wulste haben den Nachteil, dass die Rolle an diesen Stellen aufliegt, was zum Abplatzen der Chromschicht führen kann=In such rollers provided with a hard chrome layer, it has been shown that the chrome layer on the edges of the End faces are thicker than on the outer surface of the roll »These thickenings or bulges have the disadvantage that the roll rests in these places, which can lead to the chromium layer flaking off =

Um diesen Nachteil zu vermeiden, wird gemäss der Neuerung vorgeschlagen, die mit einer Chromschicht zu versehende RolleIn order to avoid this disadvantage, it is proposed according to the innovation, the role to be provided with a chrome layer

nach Ihren Stirnseiten hin ve-p- zu verjügen. Diese Verjüngung kann durch ein balliges oder kegeliges Abschleifen der Rollenenden erzielt werden. Wenn eine solche Rolle verchromt wird., so kann an dem Rand der Stirnflächen die Verdiekung vorhanden sein3 ohne dass dadurch eine Berührung dieser Verdickung mit den Auflageplatten auftritt. Auf diese einfache Weise wird
das Abplatzen der Chromschicht verhindert.ve-p- to taper towards your frontal sides. This taper can be achieved by a spherical or conical grinding of the roll ends. If such a roller is chrome-plated, the thickening can be present at the edge of the end faces 3 without this causing this thickening to come into contact with the support plates. That simple way will
prevents the chrome layer from flaking off.

Auf der Zeichnung ist ein Ausführungsbeispiel einer Rolle gemäss der Neuerung schematisch dargestellts und zwar zeigtIn the drawing, an embodiment of a roller according to the innovation is shown schematically s and that shows

Ein Brückenlager besteht beispielsweise aus der Rolle 1, die zwischen einer auf dem Fundament befestigten Platte 2 und
einer an dem Brückenaufbau befestigten Platte 3 in bekannter Weise angeordnet ist. Diese Rolle 1 ist mit einer Hartchromschichi versehen. Die Enden dieser Rolle sind nach den Stirnflächen la und Ib hin verjüngts beispielsweise durch einen balligen Abschliff Ic (Fig. 2). Wenn eine derartige Rolle mit der Hartchromschieht versehen wird., so kann ohne weiteres eine Verdickung oder eine Wulst 4 an den Enden der Rolle entstehen 9 ohne dass diese Verdickung mit der Oberfläche der Platten 2 und 3 in
Berührung kommt.A bridge bearing consists, for example, of the roller 1, which is between a plate 2 and fixed on the foundation
a plate 3 attached to the bridge structure is arranged in a known manner. This role 1 is provided with a hard chrome coating. The ends of these roller are after the end faces la and Ib through s tapered, for example, by a spherical Abschliff Ic (Fig. 2). If such a roll is provided with the hard chrome layer, a thickening or a bulge 4 can easily arise at the ends of the roll 9 without this thickening with the surface of the plates 2 and 3 in
Touch comes.
