Description

Zentriervorrichtung für Drahtspeichenradfelgen Bei Zentriervorrichtungen für Drahtspeichenradfelgen ist es bereits bekannt geworden, den axiale und zentrische Fehler anzeigenden Zeiger durch Führungsrollen zu steuern. Von diesem Bekannten unterscheidet sich die Erfindung dadurch, daß ein allseitig an einem Zapfen einer drehbaren unter Federwirkung stehenden Welle beweglich aufgehängter Zeiger zentrische und axiale Fehler gleichzeitig anzeigt.Centering device for wire spoked wheel rims For centering devices for wire-spoke wheel rims it has already become known, the axial and centric The pointer indicating errors is controlled by guide rollers. From this friend the invention differs in that one on all sides on a pin one rotating shaft under spring action movably suspended pointer centric and shows axial errors at the same time.

Auf der Zeichnung ist die Erfindung in einem Ausführungsbeispiel dargestellt und zeigt Abb. i Seitenansicht mit fortgelassenem vorderem Seitenteil, Abb. z senkrechte Vorderansicht, Abb. 3 Draufsicht auf das Fadenkreuz. Abb. q. veranschaulicht übertrieben dargestellt den Ausschlag des Zeigers bei gleichzeitigen axialen und zentrischen Fehlern, wobei der Pfeil in dem Fadenkreuz auf den Ausschlagspunkt des Zeigers hinweist.The invention is shown in an exemplary embodiment in the drawing and shows Fig. i side view with omitted front side part, Fig. z vertical Front view, Fig. 3 Top view of the crosshairs. Fig.q. illustrates exaggerated shown the deflection of the pointer with simultaneous axial and centric Errors, whereby the arrow in the crosshair points to the point of deflection of the pointer.

In einem Gehäuse a, welches die Streben b hat, die an einem Ständer oder Bock c befestigt sind, ist auf Zentrierschrauben d eine unter Wirkung einer Feder e liegende Vierkantwelle f angeordnet. Auf dieser Vierkantwelle ist um den Zapfen g schwenkbar der Zeiger h gelagert, der sich unter einem auf einer durchsichtigen Scheibe v angebrachten Fadenkreuz w bewegt, entsprechend der Bewegung seines Kontrollrades i. Auf dem Zeiger h ist eine Schere m angeordnet, deren Schenkelenden um den Bolzen za drehbar sind. An den auslaufenden Enden dieser Schere sind die Rollen o angebracht. Unter dem Zeiger h ist ein Anpreßstück P angeordnet, welches einen Langlochschlitz q besitzt (Abb. z). Dieser Langlochschlitz wird durchgriffen von dem Ansatz y des Bolzens n, an welchem eine Feder k angebracht ist, die Verbindung mit dem Anpreßstück p hat. Am unteren Ende des Anpreßstückes P befinden sich die Nocken s, die gegen die Schenkel der Schere in anliegen, beim Auseinanderdrücken der Scherenschenkel das Anpreßstück p hochschieben, das beim Nachlassen des Schenkeldruckes durch die Feder k wieder zurückgedrückt wird und hierdurch die Schenkel wieder in ihre normale Lage bringt.In a housing a, which has struts b which are fastened to a stand or bracket c, a square shaft f, which is under the action of a spring e, is arranged on centering screws d. On this square shaft, the pointer h is pivoted about the pin g and moves under a crosshair w attached to a transparent disk v , corresponding to the movement of its control wheel i. A pair of scissors m is arranged on the pointer h, the leg ends of which can be rotated about the bolt za. The rollers o are attached to the ends of these scissors. Under the pointer h a pressure piece P is arranged, which has an elongated slot q (Fig. Z). This elongated slot is penetrated by the approach y of the bolt n, on which a spring k is attached, which has the connection with the pressure piece p. At the lower end of the pressing piece P are the cams s, which rest against the legs of the scissors in, push up the pressure piece p when the scissor legs are pushed apart, which is pushed back again when the leg pressure is released by the spring k and thereby the legs back into their normal position Location brings.

Das zu zentrierende Rad wird in die Einlegenut t, nachdem zuvor die Schenkel der Schere g auseinandergedrückt sind, eingelegt und liegt das Kontrollrädchen i auf dem Innenumfang der Felge, während die Rollen o an der äußeren Wandung der Felge anliegen. Durch langsames Drehen des Rades kann nunmehr, da der Zeiger h unter der Mitte des Fadenkreuzes w liegt, eine genaue Zentrierung vorgenommen werden, weil der Zeiger sowohl in radialer, wie auch seitlicher Richtung ausschlägt und den geringsten Fehler angibt.The wheel to be centered is placed in the insertion groove after the The legs of the scissors g are pushed apart, inserted and the control wheel is located i on the inner circumference of the rim, while the rollers o on the outer wall of the Make contact with the rim. By slowly turning the wheel you can now, as the pointer h below is in the middle of the crosshair w, exact centering must be carried out, because the pointer deflects in both radial and lateral directions and indicates the least error.
