Description

Lederstulpe von U-förmigem Querschnitt für Ölpressen u. dgl. Die Lederstulpenringe von U-förmigem Querschnitt, welche in ölpressen u. dgl. angewendet werden, unterliegen infolge der außerordentlichen Druck- und Reibungsbeanspruchung einer sehr schnellen Abnutzung, so daß sie eine ständige Quelle für Betriebsstörungen und großen Kostenaufwand sind.Leather cuff with a U-shaped cross-section for oil presses and the like of U-shaped cross-section, which are used in oil presses and the like due to the extraordinary pressure and friction, a very fast one Wear and tear, making them a constant source of malfunction and great expense are.

Gemäß der Erfindung wird die Lebensdauer derartiger Lederstulpen dadurch erhöht, daß diese auf der Innenseite, welche dem Stempel anliegt, schräge Einlagen aus Metallstreifen erhalten, welche in einem geringen Abstande voneinander liegen, so daß zwischen ihnen Lederflächen stehenbleiben. Auf diese Weise wird der ganze Umfang des Stempels auf seinem Hin- und Hergange sowohl mit den Metallflächen wie auch mit den Lederflächen in Berührung gebracht, so daß einerseits die Dichtung nicht gestört wird, andererseits die Abnutzung infolge der Metalleinlagen vermindert wird. Auch wird dib Reibung vermindert, indem rauhe Stellen des Stempels durch die Metalleinlagen geglättet werden.According to the invention, the life of such leather gauntlets is thereby increases that this on the inside, which rests against the stamp, inclined deposits obtained from metal strips, which are at a small distance from each other, so that leather surfaces remain between them. This way the whole Circumference of the stamp on its back and forth both with the metal surfaces as also brought into contact with the leather surfaces, so that on the one hand the seal is not disturbed, on the other hand, the wear due to the metal inserts is reduced will. The friction is also reduced by putting rough spots on the punch through the Metal inlays are smoothed.

.Die Zeichnung stellt ein Ausführungsbeispiel der Erfindung dar. Abb. i ist eine Innenansicht eines Teiles des Lederstulpenringes, Abb.2 ist ein Querschnitt, Abb. 3 ein Teil eines Grundrisses.The drawing shows an embodiment of the invention. i is an interior view of part of the leather cuff ring, Fig 2 Figure 3 is a cross-section, Figure 3 is part of a plan.

Die Lederstulpe besteht im allgemeinen aus einem Ring von etwa 2o bis ioo cm Durchmesser und einer Höhe von etwa 8 cm. Der Querschnitt ist U-förmig. Auf die Innenfläche a des inneren Schenkels des U-Querschnittes der Lederstulpe sind Metallstreifen h gelegt, und zwar vertieft, so daB sie mit den zwischen ihnen verbleibenden Lederstellen c in einer Ebene liegen. Diese Metallstreifen b liegen schräg zur Achse und zur Bewegungsrichtung des Stempels. Sie können entweder in Aussparungen eingelegt und durch Vernietung befestigt oder von vornherein durch Druck in das Ledermaterial eingepreBt werden, und zv.,ar mit oder ohne vorherige Aussparung des Leders.The leather cuff generally consists of a ring of about 2o up to 100 cm in diameter and about 8 cm in height. The cross-section is U-shaped. On the inner surface a of the inner leg of the U-shaped cross-section of the leather cuff metal strips are placed, and deepened so that they are with the between them remaining leather areas c lie in one plane. These metal strips b lie oblique to the axis and to the direction of movement of the punch. You can either in Recesses inserted and fastened by riveting or through from the start Pressure can be pressed into the leather material, and zv., Ar with or without prior Recess of the leather.

Diese Metallstreifen bestehen aus einer geeigneten Legierung oder einem Lagermetall bekannter Art.These metal strips are made of a suitable alloy or a known type of bearing metal.
