Description
Geschlossene Führung, insbesondere Zylinderführung Die Erfindung betrifft eine geschlossene Führung, insbesondere Zylinderführung, für zwei relativ zueinander in axialer Richtung bewegliche Teile.Closed guide, in particular cylinder guide The invention relates a closed guide, in particular a cylinder guide, for two relative to each other parts moving in the axial direction.
Es ist bereits eine geschlossene Zylinderführung bekannt, bei der, um die Grenzen der Spielfreiheit möglichst gering zu halten, das innere Rohr der beiden relativ zueinander verstellbaren Teile geschlitzt wird und die Lappen vor dem Zusammenstecken nach außen gebogen werden.A closed cylinder guide is already known in which, to keep the limits of backlash as low as possible, the inner tube of the two relatively adjustable parts is slotted and the tabs in front be bent outwards when plugged together.
Es ist weiterhin zur Erzielung einer möglichst spielfreien Führung bekannt, als Passung einen Gleitsitz zu verwenden. Wenn es sich um Führungen handelt, bei denen die Länge im Vergleich zum Durchmesser der zylindrischen Teile relativ groß ist, läßt sich bei den genannten Führungsarten das Verstellglied im allgemeinen zügig bewegen. Derartige Führungen sind allerdings schwierig herzustellen, da die Mantelflächen der Teile sehr genau zueinander passen müssen. Sobald nur ganz geringfügige Abweichungen im Zylinderdurchmesser oder Abweichungen in der Zentrizität vorhanden sind, können die Teile nicht mehr spielfrei geführt werden. Dies gilt auch für Führungen, bei denen nach Art einer Keilwellenverbindung dem einen Teil mehrere in axialer Richtung verlaufende stabförmige Führungselemente zugeordnet sind, denen im anderen Teil entsprechend geformte Führungsnuten zugeordnet sind, an deren Seitenflächen die Führungselemente geführt sind, während jeweils zwischen dem Untergrund und dem Führungselement sowie zwischen den einander gegenüberliegenden Umfangsflächen der Zylinderführung Spiel vorhanden ist.It is still to achieve a lead with as little play as possible known to use a sliding fit as a fit. When it comes to guided tours, where the length is relative to the diameter of the cylindrical parts is large, the adjusting member can in general move quickly. Such guides are difficult to manufacture because the The outer surfaces of the parts must match each other very precisely. As soon as only very minor There are deviations in the cylinder diameter or deviations in the centricity the parts can no longer be guided without play. This also applies to tours, in which, in the manner of a spline connection, one part has several in an axial direction Direction extending rod-shaped guide elements are assigned to those in the other Part of correspondingly shaped guide grooves are assigned on the side surfaces the guide elements are guided, while each between the ground and the Guide element and between the opposing peripheral surfaces of the Cylinder guide play is present.
Aufgabe der Erfindung ist es, Führungen für die letztgenannte Art so zu verbessern, daß das Spiel zwischen den Schienen und Nuten völlig ausgeschaltet wird. Danach wird vorgeschlagen, die Führungselemente aus Stahlband herzustellen, das wenigstens im Bereich der Führungsnuten in Richtung auf deren Seitenflächen federnd ausgebildet wird.The object of the invention is to provide guides for the latter type to be improved so that the play between the rails and grooves is completely eliminated will. It is then proposed to manufacture the guide elements from steel strip, at least in the area of the guide grooves in the direction of their side surfaces is designed to be resilient.
Besonders vorteilhaft ist es, wellenförmige Stahlbänder zu benutzen. Es ist aber auch möglich, den Führungselementen im Bereich der Führungsnuten einen U-förmigen Querschnitt zu geben, dessen Schenkel sich gegen die Seitenflächen der Führungsnuten anlegen.It is particularly advantageous to use wave-shaped steel strips. But it is also possible to have the guide elements in the area of the guide grooves To give a U-shaped cross-section, the legs of which are against the side surfaces of the Create guide grooves.
In der Zeichnung ist die Erfindung beispielsweise dargestellt. Es zeigt F i g. 1 eine Zylinderführung mit gewellten Schienen in perspektivischer Darstellung, F i g. 2 eine gewellte Schiene im Querschnitt, F i g. 3 eine gewellte Schiene im Längsschnitt, F i g. 4 eine in Längsrichtung umgebogene Schiene im Querschnitt. In F i g. 1 sind am feststehenden Zylinder 1 vier um 90° versetzt angeordnete, in axialer Richtung verlaufende Schienen 2 befestigt. Diese greifen, wie aus F i g. 4 hervorgeht, mit ihren umgebogenen Enden in Nuten 3 des beweglichen Teiles 4 ein. Während die Seitenflächen der Schienen spielfrei an den Nuten anliegen, ist dagegen zwischen dem Untergrund 5 und den Schienen 2 sowie auch zwischen den einander gegenüberliegenden Umfangsflächen 6 und 7 der Zylinderführung Spiel vorhanden.In the drawing, the invention is shown as an example. It shows F i g. 1 shows a cylinder guide with corrugated rails in a perspective view, FIG. 2 shows a corrugated rail in cross section, FIG. 3 shows a corrugated rail in longitudinal section, FIG. 4 shows a rail bent in the longitudinal direction in cross section. In Fig. 1, four rails 2, which are arranged offset by 90 ° and run in the axial direction, are attached to the stationary cylinder 1. As shown in FIG. 4 it can be seen, with their bent ends in grooves 3 of the movable part 4 . While the side surfaces of the rails rest against the grooves without play, there is, however, play between the substrate 5 and the rails 2 and also between the opposing circumferential surfaces 6 and 7 of the cylinder guide.
Nach F i g. 2 und 3 ist das zwischen den relativ zueinander beweglichen Teilen 8 und 9 angeordnete Führungselement 10 gewellt. Es greift in die Nut 11 des Teiles 9 ein und enthält zwei Lappen 12, mit denen es in den Einschnitten 13 des Teiles 8 befestigt ist.According to FIG. 2 and 3, the guide element 10 arranged between the parts 8 and 9 that are movable relative to one another is corrugated. It engages in the groove 11 of the part 9 and contains two tabs 12 with which it is fastened in the incisions 13 of the part 8.
