Abstract

A coupling which consists of an elastomer member and an inner metal hub (7), is produced using an arrangement comprising a piston (2), mold upper and lower sections (3,4), a mold chamber and a nozzle channel (6). The inner hub has at least one bore (8) through which the elastomer is fed into the mold. The elastomer is then vulcanized.

Description

Die Erfindung betrifft ein Verfahren zur Herstellung einer Kupplung, bestehend
The invention relates to a method for producing a clutch, consisting of

  • - aus einem Bauteil aus elastomerem Werkstoff, beispielsweise auf der Basis von Siliconkautschuk (DE-A-44 22 048), und einer Innennabe aus Metall, unter Verwendung einer Vorrichtung, umfassend- From a component made of elastomeric material, for example based on Silicone rubber (DE-A-44 22 048), and an inner hub made of metal, using a device comprising
  • - einen Kolben, ein Formoberteil, ein Formunterteil, ein Formnest sowie einen Düskanal.- A piston, an upper mold part, a lower mold part, a mold cavity and one Nozzle channel.

Bislang wird bei der Herstellung einer Kupplung mit Innennabe der elastomere Werkstoff direkt in das Formnest eingedüst. Diese Fertigungsart führt jedoch dazu, daß die Eindüsnippel nach der Vulkanisation entweder erhaben über der Elastomeroberfläche bleiben oder abgeschliffen werden müssen, da an der Andüsung bei Belastung Einrisse im Elastomer entstehen können.So far, the production of a coupling with an inner hub of the elastomer Material injected directly into the mold cavity. However, this type of production means that after vulcanization, the injection nipples are either raised above the The elastomer surface remains or has to be sanded, because of the die cracks can occur in the elastomer when loaded.

Das erfindungsgemäße Verfahren unter Umgehung dieser Problematik zeichnet sich nun dadurch aus, daß
The method according to the invention while avoiding this problem is characterized in that

  • - die Innennabe mit wenigstens einer Bohrung versehen ist, durch die mittels des Düskanals, der auf der Außenseite der Innennabe in die Bohrung mündet, der elastomere Werkstoff in das Formnest eingedüst wird, wobei nach Beendigung des Füllvorganges vulkanisiert wird.- The inner hub is provided with at least one hole through which by means of Nozzle channel, which opens into the bore on the outside of the inner hub, the elastomeric material is injected into the mold cavity, after completion of the Filling process is vulcanized.

Zweckmäßige Ausgestaltungen des erfindungsgemäßen Verfahrens sind:
Appropriate embodiments of the method according to the invention are:

  • - Die Innennabe ist mit wenigstens zwei Bohrungen versehen, die mit dem Düskanal in Verbindung stehen. Besonders vorteilhaft ist es, vier bis acht Bohrungen vorzusehen, die vorzugsweise innerhalb der Nabenfläche verteilt angeordnet sind.- The inner hub is provided with at least two holes, the one with the nozzle channel keep in touch. It is particularly advantageous to have four to eight holes to be provided, which are preferably arranged distributed within the hub surface.

Der haftende Verbund zwischen dem Elastomer und der Innennabe aus Metall erfolgt durch Vulkanisation. Dadurch daß die Bohrungen mit elastomerem Werkstoff bleibend ausgefüllt werden, entsteht eine zusätzliche Verankerung des elastomeren Bauteiles mit der Innennabe.The adhesive bond between the elastomer and the inner hub is made of metal through vulcanization. Because the holes with elastomeric material remain are filled in, there is an additional anchoring of the elastomeric component with the inner hub.

Die Erfindung wird nun anhand eines Ausführungsbeispiels unter Bezug auf zwei schematische Zeichnungen erläutert.The invention will now be explained using an exemplary embodiment with reference to two schematic drawings explained.
