Abstract

Die Erfindung betrifft eine Verbindung einer Welle mit einem Mitnehmer, wobei der Mitnehmer einen Durchbruch zur Aufnahme der Welle besitzt, und wenigstens ein Teil des Durchbruchs und ein im Bereich des Durchbruchs positioniertes Teil der Welle eine Polygonstruktur aufweist zur Erzeugung einer Verdrehsicherung und wobei wenigstens die Welle aus einem thermoplastischen Kunststoff besteht und einen Ansatz aufweist, der eine Vernietung zwischen Welle und Mitnehmer aufgrund eines Kunststoffschweißvorgangs ermöglicht, wobei wenigstens Teile des Durchbruchs im Spaltbereich zwischen Welle und Durchbruch durch Schweißaustrieb ausgefüllt werden.The invention relates to a compound of a shaft with a driver, wherein the driver has an opening for receiving the shaft, and at least a portion of the aperture and positioned in the region of the aperture portion of the shaft has a polygonal structure for generating a rotation and at least the shaft consists of a thermoplastic material and having a lug which allows riveting between the shaft and carrier due to a plastic welding operation, wherein at least parts of the opening in the gap region between the shaft and breakthrough are filled by welding expulsion.

Description

Technisches GebietTechnical area

Die Erfindung betrifft eine Verbindung einer Welle mit einem Mitnehmer, wobei der Mitnehmer einen Durchbruch zur Aufnahme der Welle besitzt.The Invention relates to a connection of a shaft with a driver, wherein the driver has a breakthrough for receiving the shaft.

Stand der TechnikState of the art

Solche Verbindungen sind im Stand der Technik allgemein gekannt.Such Compounds are well known in the art.

Üblicherweise wird ein Verklemmen oder Verspannen der Welle mit dem Mitnehmer bevorzugt. Ein Nachteil besteht darin, dass bei längerer Betriebsdauer sich diese Verbindung löst und dadurch eine spielfreie Verbindung nicht mehr gewährleistet wird.Usually is a jamming or distortion of the shaft with the driver prefers. A disadvantage is that with longer operating time this connection dissolves and thus a backlash-free connection is no longer guaranteed.

Offenbarung der ErfindungDisclosure of the invention

Der Erfindung liegt die Aufgabe zugrunde, diese Nachteile zu vermeiden.Of the Invention is based on the object to avoid these disadvantages.

Die Aufgabe wird durch die Merkmale des unabhängigen Anspruchs 1 gelöst.The The object is solved by the features of independent claim 1.

Der wesentliche Vorteil der Lösung besteht darin, dass die Welle aus einem thermosplastischen Kunststoffmaterial besteht und durch einen Kunststoffschweißvorgang eine Vernietung der Welle an dem Mitnehmer erfolgt, wobei Teile des Schweißaustriebs in einen Spalt zwischen Welle und Mitnehmer eintreten und dort für eine spielfreie Verbindung sorgen.Of the substantial advantage of the solution is that the shaft made of a thermosplastic plastic material exists and by a plastic welding process riveting the Shaft is made on the driver, with parts of the welding expulsion enter a gap between the shaft and driver and there for a play-free Make connection.

Kurze Beschreibung der ZeichnungenBrief description of the drawings

1 zeigt in einer dreidimensionalen Darstellung eine Welle, an der eine Klappe angeformt ist. 1 shows in a three-dimensional representation of a wave on which a flap is formed.

2 zeigt diese Welle in einer Schnittdarstellung eines Systems mit einem Mitnehmer. 2 shows this wave in a sectional view of a system with a driver.

3 zeigt die in dem Mitnehmer vernietete Welle. 3 shows the riveted in the driver shaft.

Ausführungsform(en) der ErfindungEmbodiment (s) the invention

In 1 ist eine Welle gezeigt, an der eine linksseitig teilweise erkennbare Klappe angeformt ist. Diese Welle besitzt eine polygone Struktur für eine Drehmomentübertragung. Eine solche Struktur besitzt auch ein weiter unten beschriebener Mitnehmer. Außerdem besitzt die Welle rechtsseitig am Ende einen Zapfen, der zu einer Nietverbindung umgeformt wird. Das gesamte Gebilde besteht aus einem thermoplastischen Kunststoff. Dies bedeutet, dass eine Umformung über ein Ultraschall- oder Vibrationsschweißverfahren erfolgen kann.In 1 a shaft is shown on which a left side partially recognizable flap is formed. This shaft has a polygonal structure for torque transmission. Such a structure also has a follower described below. In addition, the shaft has a pin on the right side at the end, which is converted into a riveted joint. The entire structure consists of a thermoplastic material. This means that a deformation can take place via an ultrasonic or vibration welding process.

2 zeigt die in 1 dargestellte Welle, die in die Aufnahme eines Mitnehmers eingesteckt wird. Dieser Mitnehmer weist einen Durchbruch auf und, wie bereits beschrieben, im polygonen Bereich der Welle ebenfalls eine analoge, polygone Struktur. Der Zapfen an der Welle besitzt eine Aufnahme für eine Schweißelektrode zur Umformung des Zapfens in eine Nietstruktur. Der Mitnehmer ist mit einer Formdichtung gegenüber einem Gehäuse abgedichtet. 2 shows the in 1 illustrated shaft which is inserted into the receptacle of a driver. This driver has a breakthrough and, as already described, in the polygonal region of the wave also has an analog, polygonal structure. The pin on the shaft has a receptacle for a welding electrode for forming the pin in a rivet structure. The driver is sealed with a molded seal against a housing.

3 zeigt die Welle und den Mitnehmer nach dem Schweißvorgang. Die Welle selbst bzw. der Zapfen an der Welle ist bogenförmig zum Nietkopf umgeformt. Der Schweißaustrieb, der dabei entstanden ist, befindet sich in dem Spalt zwischen Mitnehmer und Welle und sorgt somit für eine spielfreie Verbindung zwischen Welle und Mitnehmer, sowohl in axialer Richtung als auch in tangentialer Richtung. 3 shows the shaft and the driver after the welding process. The shaft itself or the pin on the shaft is formed arcuate to the rivet head. The Schweißaustrieb that has arisen, is located in the gap between the driver and shaft and thus ensures a backlash-free connection between the shaft and driver, both in the axial direction and in the tangential direction.
