Abstract

The invention concerns a process for manufacturing an elastic rubber universal joint mounted between the flanges of two shafts with a common axis. A rubber universal joint of this type has at least three rigid sleeves mounted concentrically for the attachment on each of the two shaft flanges and has several other rigid parts, for example stop disks. The sleeves are connected to each other by elastic means. Both the sleeves and the elastic means connecting them are embedded in an elastomeric material. The elastic rubber universal joint is manufactured by direct combination as follows. First a plastic skeleton incorporating the sleeves and the several other rigid parts is made by an injection moulding device. Rubber is then injected around the plastic skeleton. The rubber is then vulcanized.

Description

Verfahren zur Herstellung einer Gelenkscheibe Method of manufacturing a joint disc

Die Erfindung betrifft ein Verfahren zur Herstellung einer zwischen zwei gleichachsigen Wellenflanschen anzuordnenden elastischen Gelenkscheibe, die mit minde¬ stens jeweils drei für die Befestigung an jedem der beiden Wellenflansche konzentrisch angeordneten starren Hülsen versehen ist und die etwaige weitere starre Teile aufweist, beispielsweise Anschlagscheiben, wobei die Hülsen durch elastische Mittel miteinander verbunden und sowohl die Hülsen als auch die sie verbindenden elasti¬ schen Mittel in einem elastomeren Werkstoff eingebettet sind.The invention relates to a method for producing an elastic joint disk to be arranged between two coaxial shaft flanges, which is provided with at least three rigid sleeves arranged concentrically for attachment to each of the two shaft flanges and which has any further rigid parts, for example stop disks, the Sleeves connected to each other by elastic means and both the sleeves and the elastic means connecting them are embedded in an elastomeric material.

Gelenkscheiben der vorgenannten Art müssen relativ hohe Drehmomente übertragen und darüber hinaus drehelastisch sowie winkel- und längsbeweglich sein. Sie bestehen vorwiegend aus einem elastischen Werkstoff, beispiels¬ weise aus Gummi, in den die Hülsen eingebettet sind, die die Verbindungsbolzen zur Ankupplung der beiden Wellen¬ flansche aufnehmen. Damit der elastische Werkstoff nicht unzulässig überbeansprucht wird, sind die darin einge¬ betteten Hülsen durch Elemente miteinander verbunden, die eine andere Elastizität als der elastische Werkstoff aufweisen. Diese bekannten Gelenkscheiben erfordern eine sehr aufwendige Fertigung.Articulated disks of the aforementioned type have to transmit relatively high torques and also have to be torsionally flexible as well as angularly and longitudinally movable. They mainly consist of an elastic material, for example of rubber, in which the sleeves are embedded, which receive the connecting bolts for coupling the two shaft flanges. So that the elastic material is not excessively overstressed, the sleeves embedded therein are connected to one another by elements which have a different elasticity than the elastic material. These known joint disks require a very complex production.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zu schaffen, mit dem die Fertigung von Gelenkscheiben wesentlich vereinfacht werαen kann.The invention has for its object to provide a method with which the manufacture of joint disks can be significantly simplified.

Die Lösung der gestellten Aufgabe besteht darin, daß dieThe solution to the problem is that

Direktverbund erfolgt, in der Weise, daß zunächst unter Einbeziehung der Hülsen und der etwaigen weiteren starren Teile mittels einer Kunststoffeinspritz¬ vorrichtung ein Kunststoffskelett gebildet und sodann dieses Kunststoffskelett mit Kautschuk umspritzt wird und daß anschließend die Vulkanisation des Kautschuks erfolgt.Direct connection takes place in such a way that initially including the sleeves and any other rigid parts are formed by means of a plastic injection device, a plastic skeleton and then this plastic skeleton is extrusion-coated with rubber and that the vulcanization of the rubber then takes place.

In Ausgestaltung der Erfindung ist das Kunststoffskelett aus einem Werkstoff gebildet, der ohne zusätzliche Haftvermittlersysteme in der Lage ist, eine direkte Verbindung mit Kautschuk einzugehen. Dadurch wird das erfindungsgemäße Verfahren weiter vereinfacht, da sich das Aufbringen von Haftvermittlern erübrigt.In an embodiment of the invention, the plastic skeleton is formed from a material that is able to form a direct connection with rubber without additional adhesion promoter systems. This further simplifies the method according to the invention, since there is no need to apply adhesion promoters.

Vorteilhafterweise wird für die Herstellung der Ge- lenkscheibe das Kunststoffskelett bei Verwendung von Naturkautschuk aus einem Polyphenylenoxid oder einem Polyphenylenether und bei Verwendung von synthetischem Kautschuk aus einem Polyamid, vorzugsweise der Typen PA 6/12 oder 12, gebildet.The plastic skeleton is advantageously formed from a polyphenylene oxide or a polyphenylene ether when using natural rubber and when using synthetic rubber from a polyamide, preferably of types PA 6/12 or 12, for the production of the joint disk.

Zur Verstärkung des Kunststoffskeletts sind nach einem weiteren Merkmal der Erfindung dem das Kunststoffskelett bildenden Werkstoff Fasern aus Glas, Kohlenstoff oder Metall beigemengt.To reinforce the plastic skeleton, fibers of glass, carbon or metal are added to the material forming the plastic skeleton according to a further feature of the invention.

Bei einer bevorzugten Ausführungsform des erfindungs¬ gemäßen Verfahrens werden folgende Verfahrensschritte ausgeführt:In a preferred embodiment of the method according to the invention, the following method steps are carried out:

- Einlegen der Hülsen und der etwaigen weiteren starren Teile in ein entsprechend gestaltetes Werkzeug,- inserting the sleeves and any other rigid parts into a suitably designed tool,

- Bildung eines KunststoffSkeletts durch Umspritzen der Hülsen und der etwaigen weiteren starren Teile mit einem elastischen Kunststoff,Formation of a plastic skeleton by overmolding the sleeves and any other rigid parts with an elastic plastic,
