Description

Bei der Lagerung von Achsen mittels Gleitlager treten vielfach Schwierigkeiten dadurgh auf, daß infolge von Ungenauigkeiten bei der Herstellung die Lager der beiden Achsenenden nicht ohne weiteres fluchten: Insbesondere macht sich 'dieses bei Kohlelagern, die man neuerdings viefach anstatt Kugelrollenlager u. dgl. verwendet, nachteilig bemerkbar. Die Kohlelager werden in der Weise hergestellt, daB man eine Buchse aus Kohle, z. B. aus feingepulverter Kohle, preßt und dann sintert und diese Buchse in die Maschine einsetzt. Bei den bisher benutzten Kugellagern werden geringe Unterschiede bei der Herstellung dadurch ausgeglichen, daß sie eine gewisse Nachgiebigkeit in der Ebene senkrecht zur Achse aufweisen. Bei Gleitlagern, insbesondere bei Kohlelagern, ist dieses jedoch nicht der Fall.When supporting axles by means of plain bearings, difficulties often arise dadurgh on that as a result of inaccuracies in manufacture the bearings of the two Axle ends do not align easily: This is particularly important with coal bearings, which have recently been used many times instead of ball roller bearings and the like, disadvantageous noticeable. The coal bearings are made in such a way that a bushing is made Coal, e.g. B. from finely powdered coal, presses and then sintered and this socket inserts into the machine. There are slight differences in the ball bearings used so far compensated in the production by the fact that they have a certain resilience in the plane perpendicular to the axis. With slide bearings, especially with coal bearings, however, this is not the case.

Die Erfindung schlägt daher vor, das Lager in einer membranartigen Halterung aufzunehmen, so däß trotz der Starrheit des Lagers selbst eine gewisse-Nachgiebigkeit erzielt wird.The invention therefore proposes the bearing in a membrane-like Take up bracket, so that despite the rigidity of the bearing itself a certain flexibility is achieved.

In der Abbildung ist eine beispielsweise Ausführungsform dargestellt. Das Lager K, z. B. ein aus einem geprellten und gesinterten Kohlekörper--bestehendes Kohlelager, ist- in einer Hülse H aufgenommen, die selbst wiederum durch eine Membran l'VI getragen wird. Hülse und Membran können aus einem Stück gezogen sein. Die Membran ist, um ihre Elastizität zu. vergrößern, mit einer Sicke S versehen. Die Membran selbst ist im Lagerschild L in geeigneter Weise gefaßt. Hierdurch wird einerseits eine genügende Nachgiebigkeit des Lagers in seiner Stellung gewährleistet; um Ungenauigkeiten abzugleichen, andererseits trotzdem eine genügende Sicherung der Lagerung erreicht. Man hat es ohne weiteres in der Hand, die Membran aus geeignetem Material und geeigneten Abmessungen zu- wählen, um den gewünschten Zweck zu erreichen.An example embodiment is shown in the figure. The camp K, z. B. from a bruised and sintered carbon body - existing Coal bearing is contained in a sleeve H, which in turn is covered by a membrane l'VI is worn. Sleeve and membrane can be drawn from one piece. The membrane is to increase their elasticity. enlarge, provided with a bead S. The membrane itself is contained in the end shield L in a suitable manner. This is on the one hand ensures sufficient flexibility of the bearing in its position; about inaccuracies to adjust, on the other hand, a sufficient security of the storage is achieved. One has it in hand, the membrane made of suitable material and suitable Choose dimensions to achieve the desired purpose.
