Abstract

The roller bearing is for use between two bodies parallel to each other and moving for a relatively short distance. Each roller (3) is of cylindrical section, with semicylindrical beads along the edges (4). The bodies (1,2) have trapezium-section grooves parallel (5,6) to each other and to the roller axis, the groove base being wider and the opening narrower than the roller diameter over the beads, behind which the oblique faces of the grooves engage. The design ensures the roller stays in place when relieved of load.

Description

Rollenlager für kleine VerschiebewegeRoller bearings for small displacement distances

Die vorliegende Erfindung betrifft ein Rollenlager nach dem Oberbegriff des Schutzanspruches. Eine Lagerung verschiedener Teile aufeinander ist oft erforderlich, um z. B. unterschiedliche Wärmedehnungen zwischen diesen Teilen zu kompensieren. Dabei führen diese Teile zueinander nur verhältnismäßig geringe Bewegungen aus.The present invention relates to a roller bearing according to the preamble the right to protection. It is often necessary to store different parts on top of one another, to z. B. to compensate for different thermal expansions between these parts. These parts only perform relatively small movements with respect to one another.

Die Verwendung von Rollenlagern zu diesem Zweck ist bekannt; ohne die Anwendung besonderer aufndiger Käfigkonstruktionen bereitet es jedoch Schwierigkeiten, eine solche Zylinderrolle an ihren vorgesehenen Platz zu halten, insbesondere wenn die Lagerflächen gegen die Horizontale geneigt sind und/oder ganz besonders dann, wenn damit gerechnet werden muß, daß das obere, das Lager belastende Teil auch nur kurzfristig abhebt.The use of roller bearings for this purpose is known; without However, the use of special complex cage constructions makes it difficult to keep such a cylindrical roller in its intended place, especially if the storage areas are inclined to the horizontal and / or especially then, if it has to be expected that the upper, the bearing loading part also only takes off at short notice.

Aufgabe der vorliegenden Erfindung ist eine Lagerkonstruktion, die sicherstellt, daß die Rolle auch bei Entlastung des Lagers an ihrem vorgesehenen Platz bleibt. Dabei soll das Lager leicht montierbar und demontierbar sein.The object of the present invention is a bearing structure that makes sure the role is played too Relief of the camp at theirs designated space remains. The bearing should be easy to assemble and dismantle be.

Zur Lösung dieser Aufgabe wird eine Konstruktion vorgeschlagen, wie sie durch die im Schutzanspruch aufgeführten Merkmale definiert ist. Dadurch, daß die aufeinander zu lagernden Körper nur geringe Bewegungen zueinander ausführen, braucht die Rolle bei entsprechend größerem Abstand zwischen den Körpern nur den Bruchteil einer Umdrehung zu machen, und dementsprechend kommt sie auch nur auf einen Teil ihres Umfanges in Kontakt mit den Lagerflächen der Körper. Auf die volle Zylinderform der Rolle kann also verzichtet werden, was die Möglichkeit schafft, die Lagerschalen so auszugestalten, daß sie in die Kontur des Zylinders hineinragen und dadurch die Bewegungsmöglichkeiten der Rolle auf das gewünschte Maß einschränken. Da sich die Rolle frei von diesen Flächen drehen soll , ist eine zweckmäßigerweise ebenfalls kreisbogenförmige Ausgestaltung ihrer Kontur in diesem Bereich.To solve this problem, a construction is proposed, such as it is defined by the features listed in the protection claim. As a result of that the bodies to be placed on top of one another only make slight movements to one another, If the distance between the bodies is correspondingly larger, the role only needs the To make a fraction of a turn, and accordingly it only comes up part of its circumference in contact with the bearing surfaces of the bodies. To the full The cylindrical shape of the roll can therefore be dispensed with, which creates the possibility of design the bearing shells so that they protrude into the contour of the cylinder and thereby limit the movement possibilities of the roller to the desired extent. Since the roller should rotate freely from these surfaces, one is expedient also circular arc-shaped design of their contour in this area.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt, und zwar zeigt diese zwei Körper 1, 2, die aufeinander gelagert werden müssen. Dabei brauchen die Lagerflächen nicht, wie hier dargestellt, horizontal zu verlaufen, sie können auch senkrecht oder geneigt angeordnet sein. Der Abstand zwischen den Körpern wird durch eine Rolle 3 überbrückt, die in ihrer Grundform einen Zylinderabschnitt bildet. Mit ihrer kreisförmigen Kontur kann die Rolle sich ohne weiteres auf den geraden Lagerflächen der Körper 1, 2 abwälzen. In die Kreisbogenkontur einlaufend sind an den Rändern der (gedachten) Schnittflächen des Zylinder- abschnitts Wulste 4 von etwa halbzylindrischer Gestalt angeordnet. Die Körper 1 bzw. 2 sind mit trapezförmigen Nuten 5 bzw. 6 versehen, wobei die Schrägen oder Flanken dieser Nuten mit einem geringen Abstand zur Rollenoberfläche hinter die Wulste 4 fassen und so die Rolle 3 in einer definierten Lage zum jeweiligen Körper halten, auch wenn das Lager entlastet wird. Die kreisbogenförmigen Teile der Rollenoberfläche und die entsprechenden Lagerflächen in den Nuten 5, 6 sind in der üblichen Weise oberflächenvergütet.An embodiment of the invention is shown in the drawing, namely this shows two bodies 1, 2, which have to be stored on top of one another. Included The storage areas do not need to run horizontally, as shown here, they can also be arranged vertically or inclined. The distance between the Bodies is bridged by a roller 3, which in its basic shape is a cylinder section forms. With its circular contour, the role can easily be on the roll straight bearing surfaces of the body 1, 2. Entering the circular arc contour are at the edges of the (imaginary) cut surfaces of the cylinder section 4 arranged beads of approximately semi-cylindrical shape. The bodies 1 and 2 are respectively provided with trapezoidal grooves 5 and 6, the bevels or flanks of these Grip grooves behind the beads 4 at a small distance from the roller surface and so keep the roller 3 in a defined position to the respective body, too when the warehouse is relieved. The circular arc-shaped parts of the roller surface and the corresponding bearing surfaces in the grooves 5, 6 are in the usual manner surface-treated.

Die bei dieser Lagerkonstruktion mögliche Verschiebna zwischen den Körpern 1, 2 ist mit "S" bezeichnet. LeerseiteThe displacement between the two possible with this bearing construction Bodies 1, 2 is labeled "S". Blank page
