Abstract
Description
Hintergrund der ErfindungBackground of the invention
(a) Bereich der Erfindung(a) Field of the invention
Die Erfindung betrifft einen Geräuschdämpfer für einen Hochgeschwindigkeitskugelgewindetrieb, insbesondere für eine Konstruktion, bei der besonders bei hohen Geschwindigkeiten Zusammenstöße und die damit verbundene Geräuschentwicklung vermieden und Reibungsgeräusche weitgehend ausgeschaltet werden.The The invention relates to a silencer for a High-speed ball screw, in particular for a construction, at the especially at high speeds collisions and the associated noise development avoided and friction noise be largely switched off.
(b) Beschreibung des derzeitigen Standes der Technik(b) description of the current State of the art
Herkömmliche Kugelgewindetriebe erzeugen keine Geräusche durch Kugelzusammenstöße, da jeweils zwischen zwei Kugeln ein Stück Kunststoff den direkten Zusammenstoß von Metall mit Metall verhindern.conventional Ball screws produce no noise due to ball collisions, as each case between two balls a piece Plastic prevent the direct collision of metal with metal.
Das japanische Patent No. 2000-355278 beschreibt einen geräuscharmen Kugelgewindetrieb mit einem Kugelkäfig, der aus je einem dicken Stück Kunststoff vor und hinter der Kugel und dünnenen Verbindungsteilen zwischen den beiden Stücken besteht, wobei die Mutter extra Rillen hat, in denen die Verbindungsteile laufen können. Auf der Mutter ist eine Kugelrückführung in Form eines umgedrehten "U" angebracht. Unten an der Mutter sind Aushöhlungen, die es erlauben die Niederhaltestücke der Kugelkäfige einzusetzen und einen geschlossenen Kugelumlaufpfad zu schaffen. Die ganze Konstruktion ist kompliziert und aufwendig. Die große Anzahl an Bauelementen muß einzeln zwischen Mutter und Spindel eingebracht werden. Die Möglichkeiten zur Kostensenkung sind klein, die Fehlermöglichkeiten groß.The Japanese Patent No. 2000-355278 describes a low-noise Ball screw with a ball cage, each made of a thick Piece of plastic in front of and behind the ball and thin connecting parts between the two pieces where the nut has extra grooves in which the connecting parts be able to walk. On the mother is a ball return in Shape of an inverted "U" attached. Below at the mother are excavations, which allow to use the hold-down pieces of ball cages and to provide a closed recirculating ball path. The whole construction is complicated and expensive. The large number of components must be individually be introduced between the nut and spindle. The possibilities to reduce costs are small, the possibility of errors large.
Ein weiteres japanisches Patent, No. 2001-99257 geht von einer Anzahl Stahlkugeln und einem Kugelkäfig aus. Auch hier sind die einzelnen Abteile für die Kugeln zu einer Kette verbunden. Auf der Mutter befinden sich Kugelein- und Auslaß und die Kugeln können in den Gewinderillen rollen. Ein Problempunkt ist bei dieser Konstruktion das Kettenschloß, das zu Störungen bei der Bewegung der Kugeln führen kann. Auch die kleinen Umlenkradien der Kugelumlenkung können bei dieser Konstruktion leicht Probleme beim Kugelumlauf hervorrufen und den Geräuschdämpfungseffekt verringern.One another Japanese patent, no. 2001-99257 goes from a number Steel balls and a ball cage out. Again, the individual compartments for the balls to a chain connected. On the mother are ball inlet and outlet and the Balls can roll in the thread grooves. One problem is with this construction the chain lock, that to disruptions when moving the balls lead can. Even the small radii of the ball deflection can at This construction can easily cause problems in the ball circulation and the silencing effect reduce.
Zusammenfassung der ErfindungSummary of the invention
Hauptziel der vorliegenden Erfindung ist ein geräuscharmer Hochgeschwindigkeitskugelgewindetrieb.main goal The present invention is a low-noise high-speed ball screw.
Nebenziel der Erfindung ist es, eine Konstruktion zu finden, die einfach und leicht zu implementieren ist und eine einfache und schnelle Massenproduktion bei kleiner Fehlerrate erlaubt.secondary objective The invention is to find a construction that is simple and easy to implement and easy and fast mass production allowed at low error rate.
Zur Erreichung der obigen Ziele besteht die Erfindung im wesentlichen aus einer Mutter, einer Spindel, mindestens zwei ovalen Ringen mit Kugeln, sowie Dichtungen und einer Hülse. Die Mutter hat eine zentrale Längsbohrung mit einem Gewinde für die Aufnahme der Spindel. Außerdem hat sie für jeden Ring mit Kugeln eine Öffnung zum Einführen des Rings. Die Ringe sind dabei so angebracht, daß die Kugeln, die Eingriff in das Gewinde haben immer gleichmäßig über den Umfang verteilt sind. Durch die ovale Form der Ringe wird erreicht, daß die Kugeln immer leicht in den Ringen rollen können.to To achieve the above objects, the invention substantially from a nut, a spindle, at least two oval rings with Balls, as well as gaskets and a sleeve. The mother has a central longitudinal bore with a thread for the Recording the spindle. Furthermore she has for each ring with balls an opening for insertion of the ring. The rings are mounted so that the balls, the engagement in the threads are always evenly distributed around the circumference. Due to the oval shape of the rings is achieved that the balls always easy in can roll the rings.

Die Anwendung der vorliegenden Erfindung auf die Mutter eines Kugelgewindetriebs besteht darin, daß die Tiefe der Kugelführungsöffnungen über die Achse der Mutter hinausgeht und daß Kugelführungen, in denen die Kugeln in Ketten angeordnet sind in die Kugelführungsöffnungen eingesetzt werden. Durch geeignete Verteilung über den Umfang wird dabei dafür gesorgt, daß die Kugeln gleichmäßig über den gesamten Umfang tragen. Dies verhindert das Entstehen von Laufgeräuschen.The Application of the present invention to the nut of a ball screw is that the Depth of the ball guide openings over the Axis of the mother goes out and that ball guides, in which the balls arranged in chains are used in the ball guide holes. Through suitable distribution over the scope is going for it taken care that the Balls evenly over the wear the entire circumference. This prevents the development of running noise.
