Kugelgewindetriebe müssen, wenn sie beispielsweise in Lenkvorrichtungen von Kraftfahrzeugen eingesetzt werden, möglichst geräuscharm arbeiten. Die Hersteller von Kraftfahrzeugen fordern die Entwicklung möglichst geräuscharm arbeitender Kugelgewindetriebe. Die Nutzer von Kraftfahrzeugen akzeptieren Lenkgeräusche nicht.Ball Screws have to, if, for example, in steering devices of motor vehicles are used, if possible noise work. The manufacturers of motor vehicles are demanding development preferably noise working ball screws. Motor vehicle users accept steering noise Not.
Aufgabe der vorliegenden Erfindung ist es daher, ein Verfahren zur Herstellung eines Kugelgewindetriebes anzugeben, dessen Kugeln geräuscharm und hakelfrei insbesondere im Umlenkbereich abwälzen. Erfindungsgemäß wird diese Aufgabe durch die folgenden Verfahrenschritte zur Herstellung des Kugelgewindetriebes gelöst: Herstellen des Mutterkörpers mit der Gewindenut und der Aufnahme, Herstellen des Umlenkstückes mit der Umlenkbahn, Positionieren des Umlenkstückes in der Aufnahme derart, daß ein kantenfreier Übergang zwischen der von der Gewindenut des Mutterkörpers begrenzten Gewindebahn und der Umlenkbahn des Umlenkstückes ausgebildet ist. Das bedeutet, nach dem exakten Einsetzen des Umlenkteilstücks ist der Kugelkanal ohne weitere Bearbeitungsschritte hinsichtlich der Beseitigung von Kanten fertiggestellt.task The present invention is therefore a method of manufacture specify a ball screw drive, the balls of which are quiet and roll free of hooks, especially in the deflection area. According to the invention Task through the following process steps to manufacture the Ball screw drive solved: Manufacture of the mother's body with the thread groove and the receptacle, manufacture the deflection piece with the deflection path, positioning the deflection piece in the receptacle in such a way the existence edge-free transition between the thread path delimited by the thread groove of the nut body and the deflection path of the deflection piece is trained. That means after the exact insertion of the deflection section the ball channel without further processing steps with regard to the Removal of edges completed.
Ein kantenfreier Übergang bedeutet in diesem Zusammenhang zunächst, dass in der Ebene der Kugelbahn keine Stufe gebildet ist, an der die Kugel hörbar ankanten könnte. Ferner bedeutet der kantenfreie Übergang, dass ein Spalt zwischen der die Aufnahme begrenzenden Wandung und der Wandung des Umlenkstückes im Bereich der Kugelbahn entweder nicht ausgebildet oder zumindest so eng ausgebildet ist, dass ein hörbares Ankanten der Kugel ausgeschlossen ist.On edge-free transition in this context means first of all that in the level of Ball track no step is formed at which the ball audibly bends could. Furthermore, the edge-free transition means that a gap between the wall delimiting the receptacle and the wall of the deflection piece either not formed in the area of the ball track or at least is so narrow that audible bending of the ball is impossible is.
Die einwandfreie Anpassung des Umlenkstückes an die Aufnahme oder umgekehrt und insbesondere die Anpassung der Umfangsflächen des Umlenkstückes und der Aufnahme an der Einlauf- und der Auslaufseite der Kugeln aneinander, zusammen mit einer einwandfreien Positionierung des Umlenkstückes ermöglichen kantenfreie Übergänge zwischen dem Mutterkörper und dem Umlenkstück ohne weitere Bearbeitungsschritte, so daß die Kugeln hakelfrei und geräuscharm in das Umlenkstück ein- und aus dem Umlenkstück auslaufen. Beispielsweise kann das Umlenkstück gesteuert eingepreßt und während des Einpressvorgangs in Pressrichtung positioniert werden. Gegebenenfalls kann es erforderlich sein, das Umlenkstück mit anderen Mitteln zu befestigen, beispielsweise mit Klebstoff. Jedenfalls kann auf den kostenintesnsiven Schleifvorgang verzichtet werden, der bei bekannten Kugelgewindetrieben zur Bereitstellung kantenfreier Übergänge erforderlich ist.The perfect adaptation of the deflection piece to the receptacle or vice versa and in particular the adaptation of the peripheral surfaces of the deflection piece and the receptacle on the inlet and outlet sides of the balls, enable together with a perfect positioning of the deflection piece edge-free transitions between the mother's body and the deflector without further processing steps, so that the balls free of hooks and noise into the deflection piece in and out of the deflection piece leak. For example, the deflection piece can be pressed in and controlled during the Pressing process to be positioned in the pressing direction. Possibly it may be necessary to fix the deflection piece by other means, for example with glue. Anyway, on the cost-intensive Grinding process can be dispensed with in known ball screws required to provide edge-free transitions is.
