Description

Lagerung runder Kugelführungen Kugelführungen für leichtgängige Längsbewegungen bestehen aus einer inneren runden Welle, auf der unter Zwischenschaltung von Kugeln eine zylindrische Lagerbuchse läuft. Derartige Führungen arbeiten nur dann einwandfrei, wenn die von den Kugeln berührten Laufflächen eine möglichst harte Oberfläche besitzen, die außerdem auf das Genaueste und Feinste bearbeitet sein muß. Die zwischen innerer Welle und der Lagerbuchse laufenden Kugeln sind in einem Kugelkäfigrohr gehalten, das bekanntlich den halben Weg des gewünschten ganzen Schiebewegs der Kugelführung zurücklegt. Geringste Ungenauigkeiten an den Kugellaufflächen sowohl der inneren Welle wie der Lagerbuchse führen dazu, daß die Führung an diesen Stellen hart geht. Als Folge stellt sich ein, daß die Lagerbuchse hierdurch immer mehr auf die eine oder andere Seite der Führung wandert und den Schiebeweg der Führung verkürzt. Wenn der Schiebeweg der Führung kraftschlüssig gesteuert ist, läuft die Lagerbuchse in den Endstellungen an und verursacht Stöße. Aus Gründen eines geringen Härteverzuges und der billigen Fertigung bestehen die Lagerbuchsen aus gezogenem Spezialmaterial, deren Außenflächen zur Rohrachse rundgeschliffen werden. Die Lagerung erfolgt meistens in genau bearbeiteten geschlitzten Bohrungen, die dann durch Klemmschrauben das äußere Rohr der Kugelführung festhalten.Bearing of round ball guides Ball guides for smooth longitudinal movements consist of an inner round shaft on which balls are interposed a cylindrical bearing bush runs. Such guides only work properly if if the running surfaces touched by the balls have the hardest possible surface, which must also be worked on with the utmost precision and finest. The between inner The shaft and the bearing bush running balls are held in a ball cage tube, as is known, half the way of the desired entire sliding path of the ball guide covered. Slightest inaccuracies on the ball raceways as well as the inner ones Both the shaft and the bearing bushing mean that the guide is hard at these points. As a result, it turns out that the bearing bush is thereby increasingly focused on the one or the other side of the guide moves and shortens the sliding path of the guide. if the sliding path of the guide is non-positively controlled, the bearing bush runs in the end positions and causes shocks. For reasons of a low hardening delay and the cheap production, the bearing bushes are made of drawn special material, the outer surfaces of which are ground round to the pipe axis. The storage takes place mostly in precisely machined slotted bores, which are then connected to the Hold the outer tube of the ball guide.

Die gleichen obenerwähnten Schwierigkeiten eines ungleich harten Laufes können bei einer maßlich genauen Kugelführung durch Verspannen der Lagerbuchse in dem tragenden Lagerbock beim Einbau eintreten. Ein Ovaldrücken der Lagerbuchse wird die sehr genauen Innenpassungen aufheben und, weil alle Teile hart sind, die Führung schnell unbrauchbar machen.The same difficulties mentioned above of an unequal hard run with a dimensionally accurate ball guide by bracing the bearing bush in enter the bearing pedestal during installation. An oval press of the bearing bush is cancel the very precise inside fits and, because all parts are hard, the guide quickly render useless.

Hinzu kommt noch bei der parallelen Anordnung mehrerer Kugelführungen die besonders teuere Herstellung der Bohrungen. Es ist in der Technik bekannt, gesondert bearbeitete Buchsen oder Lagerstellen mit Metallen zu umgießen oder festzugießen. Hierdurch können die hochwertigen Laufeigenschaften einer Buchse aus gehärtetem Stahl oder Bronze in einem Maschinenkörper oder Gehäuse aus einem anderen Werkstoff, dessen Herstellung billiger ist oder wieder besondere Eigenschaften besitzt, z. B. Wärmeleitfähigkeit, ausgenutzt werden. Dieser Gedanke des Festgießens liegt dem Gegenstand der Erfindung jedoch mit einem anderen Ziel zugrunde. Durch das Festgießen, dürfen die genauen Laufeigenschaften der Kugelführung nicht verändert werden. Hierzu gehört auch, daß keine metallurgischen Veränderungen an der gehärteten Lagerbuchse eintreten dürfen. Außerdem darf sich die gewünschte Lage der Kugelführu.n@g, z. B. zu einer Fläche, durch das Vergießen nicht verändern. Diese gestellten Forderungen erfüllen Kunststoffe, die ohne Druck und Wärme aushärten, als Ausgießmaterial. Die Aushärtung des Kunststoffes beeinflußt nicht durch Erwärmung die metallurgischen Eigenschaften der gehärteten Lagerbuchse und verändert nicht die Passungsverhältnisse der Kugelführung selbst. Bekannt ist außerdem die gute Haftfähigkeit dieser Kunststoffe auf Metallen.Added to this is the parallel arrangement of several ball guides the particularly expensive production of the holes. It is known in the art separately to encapsulate or cast in machined bushings or bearing points with metal. This allows the high-quality running properties of a hardened socket Steel or bronze in a machine body or housing made of a different material, the production of which is cheaper or has special properties again, e.g. B. thermal conductivity, are exploited. This idea of pouring on is based on that However, the subject matter of the invention is based on a different aim. By pouring the exact running properties of the ball guide must not be changed. For this also includes that no metallurgical changes to the hardened bearing bush may enter. In addition, the desired position of the Kugelführu.n@g, z. B. to a surface, do not change by potting. These made demands plastics, which cure without pressure and heat, are used as pouring materials. the The hardening of the plastic does not affect the metallurgical properties through heating Properties of the hardened bearing bush and does not change the fit conditions the ball guide itself. The good adhesion of these plastics is also known on metals.

Die Erfindung wird durch die Zeichnung dargestellt. Die Kugelführung 1 kann beispielsweise in einer Vorrichtung 2 aufgenommen und zu der Lagerbockanschraubfläche ausgerichtet werden. Weil die Bohrung des Lagerbocks 3 ohnehin größer im Durchmesser sein muß als der Außendurchmesser der Lagerbuchse 4, brauchen Lagerbuchsenaußendurchmesser und Lagerbockbdh.rung nicht genau bearbeitet zu sein. Nachdem der Ringspalt zwischen Lagerbuchse und Lagerbockbohrung durch den ohne Druck und Wärme aushärtenden Kunststoff ausgegossen ist, ergibt sich in einfachster Weise die genaue Verbindung der Kugelführung mit dem Lagerbock. Parallellagerung von zwei oder mehr Kugelführungen sind in gleicher Art möglich.The invention is illustrated by the drawing. The ball guide 1 can for example be received in a device 2 and to the bearing block screwing surface be aligned. Because the bore of the bearing block 3 is larger in diameter anyway must be than the outer diameter of the bearing bush 4, need bearing bush outer diameter and bearing block brace not to be precisely machined. After the annular gap between Bearing bush and bearing block bore through the plastic that hardens without pressure or heat is poured out, the exact connection of the ball guide results in the simplest possible way with the bearing block. Parallel bearings of two or more ball guides are the same Kind possible.
