Abstract
Description
Die vorliegende Erfindung bezieht sich auf ein thermoplastisches Kunststoffbauteil, umfassend mindestens ein Drehmomentbegrenzungsmittel, durch das eine Montageschraube zur Montage des thermoplastischen Kunststoffbauteils an einem weiteren Bauteil führbar ist und das für eine Begrenzung des beim Festziehen der Montageschraube wirkenden Drehmoments geeignet und eingerichtet ist.The The present invention relates to a thermoplastic plastic component, comprising at least one torque limiting means, by the a mounting screw for mounting the thermoplastic resin component feasible on another component is and for a limitation of the tightening of the mounting screw acting Torque is suitable and set up.
Beim Verschrauben eines thermoplastischen Kunststoffbauteils mit einem weiteren Bauteil werden zur Begrenzung des beim Festziehen einer Montageschraube wirkenden Drehmoments üblicherweise Drehmomentbegrenzungsmittel aus Metall eingesetzt. Dabei kann unter Setzen einer Flanschverbindung ein Festsitz der Verschraubung gewährleistet werden. Ein Nachteil dieser aus dem Stand der Technik bekannten Lösung besteht darin, dass die Drehmomentbegrenzungsmittel aus Metall verhältnismäßig schwer sind und darüber hinaus vergleichsweise teuer sind.At the Screwing a thermoplastic plastic component with a another component are used to limit the tightening of a Mounting screw acting torque usually torque limiting means used in metal. It can under setting a flange a tight fit of the screw connection can be ensured. A disadvantage This known from the prior art solution is that the Torque limiting means of metal are relatively heavy and beyond are relatively expensive.
Hier setzt die vorliegende Erfindung an.Here uses the present invention.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein thermoplastisches Kunststoffbauteil der eingangs genannten Art mit zumindest einem Drehmomentbegrenzungsmittel zur Verfügung zu stellen, welches ein geringeres Gewicht als die aus dem Stand der Technik bekannten Lösungen aufweist und das darüber hinaus einfach und kostengünstig herstellbar ist.Of the present invention is based on the object, a thermoplastic Plastic component of the type mentioned above with at least one torque limiting means to disposal to put, which has a lower weight than that of the state the technology known solutions and that's about it In addition, simple and inexpensive can be produced.
Die Lösung dieser Aufgabe liefert ein thermoplastisches Kunststoffbauteil der eingangs genannten Art mit den Merkmalen des kennzeichnenden Teils des Anspruchs 1. Die Unteransprüche betreffen vorteilhafte Weiterbildungen der Erfindung.The solution This object is achieved by a thermoplastic plastic component of of the type mentioned above with the features of the characterizing part of claim 1. The dependent claims relate to advantageous developments of the invention.
Gemäß Anspruch 1 zeichnet sich ein erfindungsgemäßes thermoplastisches Kunststoffbauteil dadurch aus, dass das Drehmomentbegrenzungsmittel aus einem duroplastischen Kunststoff besteht. Ein Vorteil der erfindungsgemäßen Lösung besteht darin, dass das Drehmomentbegrenzungsmittel einfach und kostengünstig – insbesondere durch ein Spritzverfahren – hergestellt werden kann. Ein weiterer Vorteil besteht darin, dass das Drehmomentbegrenzungsmittel aus duroplastischem Kunststoff relativ leicht ist, so dass Gewicht eingespart werden kann.According to claim 1, a thermoplastic plastic component according to the invention is characterized from that the torque limiting means of a thermoset Plastic exists. An advantage of the solution according to the invention is that the torque limiting means simple and inexpensive - in particular produced by a spraying process can be. Another advantage is that the torque limiting means made of thermosetting plastic is relatively light, allowing weight can be saved.
Duroplastische Kunststoffe haben den Vorteil, dass sie vergleichsweise hart und robust sind. Nach der Aushärtung können duroplastische Kunststoffe nicht mehr verformt werden. Ein weiterer Vorteil duroplastischer Kunststoffe besteht darin, dass sie nach einer Erwärmung nicht weich werden und nicht aufschmelzen. Ein weiterer Vorteil eines Drehmomentbegrenzungsmittels aus einem duroplastischen Kunststoff besteht darin, dass es sich beim Ausüben einer Axialkraft nicht verformt, so dass es sich in vorteilhafter Weise auch für Schraubverbindungen eignet, bei denen hohe axiale Belastungen auftreten können.thermoset Plastics have the advantage of being comparatively hard and tough are robust. After curing can thermosetting plastics are no longer deformed. Another Advantage of thermosetting plastics is that they after a warming do not soften and do not melt. Another advantage a torque limiting means of a thermosetting plastic is that it is not when exerting an axial force deformed, so that it is also advantageous for screw suitable for which high axial loads can occur.
Das Drehmomentbegrenzungsmittel kann in bevorzugten Ausführungsformen insbesondere aus ungesättigten Polyesterharzen, Epoxidharzen, faserverstärkten Polyester- oder Epoxidharzen oder aus Polyurethanharzen bestehen.The Torque limiting means may in preferred embodiments in particular from unsaturated Polyester resins, epoxy resins, fiber-reinforced polyester or epoxy resins or consist of polyurethane resins.
In einer besonders bevorzugten Ausführungsform wird vorgeschlagen, dass das thermoplastische Kunststoffbauteil zumindest eine im Wesentlichen hohlzylindrische Durchführung aufweist, in die das Drehmomentbegrenzungsmittel formschlüssig eingesetzt ist. Dadurch kann eine sichere Festlegung des Drehmomentbegrenzungsmittels in der Durchführung des Kunststoffbauteil erreicht werden. Das Drehmomentbegrenzungsmittel ist vorzugsweise im Wesentlichen hohlzylindrisch ausgebildet.In a particularly preferred embodiment It is suggested that the thermoplastic component has at least one substantially hollow cylindrical passage, in which the torque limiting means is inserted positively. Thereby can safely fix the torque limiting means in the implementation the plastic component can be achieved. The torque limiting device is preferably formed substantially hollow cylindrical.
