Description
Bei in Rohren oder Schläuchen geführten Zug- und Druckfcabeln macht sich das zwischen Kabel und Führungswandung erforderliche Spiel in den Krümmungen insofern unangenehm bemerkbar, als es toten Gang verursacht, d. h. das Kabel gestattet Längsverschiebung des einem Kabelendes in der Führung, ohne daß es diese Bewegung zum anderen Kabelende überträgt.In the case of pulling and pushing cables routed in pipes or hoses, there is something between Cable and guide wall required play in the curvatures insofar uncomfortable noticeable as it causes dead gait, d. H. the cable allows longitudinal displacement of the one end of the cable in the guide without this movement to the the other end of the cable.
Bei mehrfacher Richtungsänderung des Kabels erreicht dieser tote Gang Ausmaße, die die Anwendung solcher Kabel für feinere VersteUvorrichtungen ausschließein.If the cable changes direction several times, this dead corridor reaches dimensions, which excludes the use of such cables for finer steering devices.
Durch die Anwendung Kleinster ToIeranzen bei der Bemessung des Spieles läßt sich der tote Gang nicht beseitigen. Da näm-■üch das Kabel selbst aus vielen einzelnen Drähten aufgebaut und manchmal obendrein mit einer Umspinnung versehen ist, ist die Einhaltung einer stets gleichbleibenden Kabeldicke praktisch kaum möglich, es führt daher auch die Anwendung engster Toleranzen bei der Konstruktion van Kabel und Führung nicht zum Ziel.By using the smallest tolerances when dimensioning the game the dead corridor does not eliminate itself. Since that is the cable itself is made up of many individual wires and is sometimes provided with a wrapping on top of that It is practically impossible to maintain a constant cable thickness, which is why it leads also the application of the tightest tolerances in the construction of cables and guides not to the goal.
Weiterhin vergrößert die natürliche Abnutzung von Kabel und Führung den toten Gang.Furthermore, the natural wear and tear on the cable and guide increases the dead Corridor.
Bei gekrümmten Führungen, die zur Verminderung der Reibung mit Rollen ausgestattet sind, wachsen die Schwierigkeiten, noch besonders, da die notwendigen Toleranzen in den Zapfen und Rollen sowie im Achsabstand die Summe der Abweichungen vom Sollmaß noch vergrößern. Tritt nun noch eine geringe Exzentrität einzelner Rollen hinzu, so kann sogar abwechselnd toter Gang und VerHemmung des Kabels leintreten.For curved guides equipped with rollers to reduce friction are, the difficulties grow, especially since the necessary tolerances Increase the sum of the deviations from the nominal dimension in the journals and rollers as well as in the center distance. Now kick Adding a slight eccentricity to individual roles can even result in an alternating dead gear and block the cable.
Die vorliegende Erfindung beseitigt nun diese Schwierigkeiten und ermöglicht die Führung des Kabels in den Krümmungen ohne toten Gang durch Anordnung von verstellbaren Führungselementen, d. h. von Backen, Kloben, von biegsamen oder gelenkigen, nötigenfalls mit Rollen ausgestatteten Führungsteilen, die einzeln durch mehrere oder' in ihrer Gesamtheit durch eine einzige Stellschraube verstellt werden können. Die Verstellbarkeit der Führungseiemiente gestattet einmal, das Spiel zwischen Kabel und Führung beliebig zu verändern, sodann dem wechselnden Kabeldurchmesser Rechnung zu tragen, ferner erlaubt sie bei Anwendung von Rollen eine viel gröbere Passung der einzelnen Teile, und endlich, gestattet sie bei Verwendung besonderer, nämlich, biegsam oder gelenkig ausgebildeter Führungselemente sogar eine geringe Exzentrizität der Rollen.The present invention now eliminates these difficulties and enables Guiding of the cable in the bends without dead gear through the arrangement of adjustable ones Guide elements, d. H. of cheeks, clamps, flexible or articulated ones, if necessary equipped with rollers Guide parts that are individually by several or 'in their entirety by a single one Adjusting screw can be adjusted. The adjustability of the guide bar allows once, to change the play between cable and guide as desired, then to take account of the changing cable diameter wear, it also allows a much coarser fit of the individual when using roles Parts, and finally, it allows when using special ones, namely, flexible or articulated guide elements even a slight eccentricity of the rollers.
