Description
Die Erfindung betrifft ein Befestigungsmittel für Maschinenteile, insbesondere für Ventilkörper in Gehäusen, z. B. zum federnden Festhalten von Ventileinsätzen in. Gehäusebohrungen.The invention relates to a fastening means for machine parts, especially for valve bodies in housings, e.g. B. for resilient holding of valve inserts in. housing bores.
Die bekannten Befestigungsmittel sind entweder Verschraubungen oder andere.Halteglieder, die gesondert, z. B. drehbar oder nachgiebig, an einem der zu verbindenden Teile befestigt werden müssen. Nach der Erfindung soll als Befestigungsmittel eine im wesentlichen haarnadelförmige Feder dienen, welche mit ihren Schenkeln in verhältnismäßig weite Löcher des Gehäuses eingeschoben und so' geformt ist, daß sie beim Einschieben durch den' Widerstand ihrer Anlagestellen arn Maschinenteil und in den Gehäusebohrungen sich selbst und das Maschinenteil am Gehäuse festspannt. Dadurch wird eine leicht lösbare und doch sicher wirkende Verbindung geschaffen, die mit einfachen Mitteln billig hergestellt werden kann und leichten Eih-und Ausbau erlaubt.The known fasteners are either screw connections or other.Halteglieder, which separately, z. B. rotatable or resilient, at one of the parts to be connected must be attached. According to the invention, as a fastening means a substantially hairpin-shaped spring are used, which with their legs in relatively wide holes of the housing inserted and so 'shaped that they are pushed in by the resistance of their contact points on the machine part and clamps itself and the machine part to the housing in the housing bores. This creates an easily detachable and yet secure connection, which can be produced cheaply by simple means and easy to assemble and expand permitted.
Zwei Ausführungsbeispiele nach der Erfindung sind in der Zeichnung dargestellt. Es zeigt Fig. i das Befestigungsmittel in nicht eingebautem Zustand, Fig. a das eingebaute Befestigungsmittel, Fig.3 eine zweite Ausführungsform, des Befestigungsmittels.Two embodiments according to the invention are shown in the drawing shown. It shows Fig. I the fastening means in the not installed state, Fig. A the built-in fastening means, Fig.3 a second embodiment, the Fastening means.
Das Befestigungsmittel ist eine Feder i, die aus einem haarnadelförmig gebogenen Federdraht mit etwa parallelen Schenkeln a und 3 und einem diese verbindenden bogenförmigen Steg q. besteht. Beide Schenkel dieser Feder sind gegen die Stegebene abgekröpft in eine Ebene, die zur Stegebene m.indestenus parallel, insbesondere aber unter einem stumpfen Winkel geneigt ist.The fastening means is a spring i, which consists of a hairpin curved spring wire with approximately parallel legs a and 3 and one connecting them arched web q. consists. Both legs of this spring are against the bridge offset in a plane that is at least partially parallel to the web, in particular but is inclined at an obtuse angle.
Soll ein Teil, z. B. ein Ventilkörper, in einer Bohrung 6 eines Maschinenteils federnd festgehalten werden, so sind in dem Maschinenteil 7 in zweckmäßiger Lage und senkrecht zur Achse der Bohrung 6 zwei Löcher 8 und 9 anzubringen, deren Durchmesser merklich größer ist als der Durchmesser des Drahtes der Feder i. In diese Löcher wird die Feder i mit ihren Schenkeln. a und 3 eingesteckt. Dabei gleiten die Kröpfstellen äm' Steg auf die Stirnfläche des Teils 5. Da der Abstand dieser Fläche des Teils 5 von einer gedachten Ebene durch die oberen Mantellinien der Bohrungen 8 und 9 wesentlich kleiner ist als der Abstand zwischen der Schenkelebene und den Kröpfstellen, spannen sich die Enden :2 und 3 der Feder in den Bohrungen 8 und 9 fest, während gleichzeitig die Kröpfstellen am Steg das- Teil 5 in die Bohrung 6 hineindrücken, so daß es fest mit dem Maschinen teil 7 'verbunden ist. Die Tiefe der Bohrungen 8 und 9 begrenzt das Einschieben der Feder i, so daß die Schenkel derselben an geeigneten Punkten auf dem Teil 5 aufliegen: Die Feder hält also in eingeschobener Lage sich selbst und, das Teil 5 fest. Zieht man die Feder i wieder heraus, so kann auch das Teil 5 ausgebaut werden.Should a part, e.g. B. a valve body in a bore 6 of a machine part are resiliently held, so are in the machine part 7 in an appropriate position and perpendicular to the axis of the bore 6 to make two holes 8 and 9, the diameter of which is noticeably larger than the diameter of the wire of the spring i. In these holes becomes the spring i with its legs. a and 3 plugged in. The crooks slide in the process äm 'web on the face of the part 5. Since the distance of this face of the part 5 from an imaginary plane through the upper surface lines of the bores 8 and 9 is significantly smaller than the distance between the plane of the thighs and the crimping points, tighten the ends: 2 and 3 of the spring in the bores 8 and 9 while at the same time the crimping points on the web press the part 5 into the bore 6, so that it is firmly connected to the machine part 7 '. The depth of the holes 8 and 9 limits the insertion of the spring i, so that the legs of the same at suitable Points rest on part 5: The spring thus holds itself in the pushed-in position itself and that part 5 stuck. If you pull the spring i out again, you can do that too Part 5 to be expanded.
In der Ausführung nach Fig. 3 besitzt die Feder io in der Nähe ihrer Stirnseite ii eine seitliche Einschnürung 1a. Diese dient als Anschlag beim Einschieben der Feder, indem sie an einen Bolzen 13 anstößt, der an dem zu befestigenden Teil 1q. angebracht ist. Dadurch bleibt an der Stirnseite i i der Feder io immer eine Öse frei, in die ein Werkzeug zum, Abziehen der Feder eingehakt werden kann.In the embodiment of FIG. 3, the spring has io in the vicinity of its Front side ii a lateral constriction 1a. This serves as a stop when inserting the spring by abutting a bolt 13 on the part to be fastened 1q. is appropriate. As a result, one always remains on the end face i i of the spring io Free eyelet into which a tool for pulling off the spring can be hooked.
