Description

Schraube oder Spindel Die vorliegende Erfindung betrifft eine Schraube, insbesondere die Steuerschraube eines beweglichen Organes einer Werkzeugmaschine. Screw or spindle The present invention relates to a screw, in particular the control screw of a movable member of a machine tool.

Diese Schraube ist erfindungsgemäß dadurch gekennzeichnet, daß sie aus einer Feder besteht, die auf einem Schaft angeordnet und mit diesem in Winkelrichtung kraftschlüssig verbunden ist. According to the invention, this screw is characterized in that it consists of a spring which is arranged on a shaft and with this in the angular direction is positively connected.

In der Zeichnung sind, tn Ansicht und teilweise im Schnitt, zwei vorteilhafte Ausführungsbeispiele der Erfindung schematisch dargestellt; Fig. 1 zeigt die Leitspindel einer Werkzeugmaschine mit einer Mutter und Fig. 2 eine Variante einer derartigen Spindel. In the drawing are, in view and partially in section, two advantageous embodiments of the invention shown schematically; Fig. 1 shows the lead screw of a machine tool with a nut and FIG. 2 shows a variant such a spindle.

Die in Fig. 1 dargestellte Spindel besteht aus einem Schaft 1, der eine Wendel-Nut 2 aufweist. Zum Teil in dieser Wendel-Nut 2 liegt eine Schraubenfeder 7 mit kreisförmigem Querschnitt, deren Windungen einen Abstand voneinander haben. The spindle shown in Fig. 1 consists of a shaft 1, the has a helical groove 2. Part of this helical groove 2 is a helical spring 7 with a circular cross-section, the turns of which are spaced apart.

Mit ihren beiden Enden 3a stößt sie gegen zwei Stifte 4, die auf dem Schaft 1 angebracht sind, wodurch sie in Winkelrichtung mit diesem Schaft kraftschlüssig verbunden ist.With its two ends 3a, it abuts against two pins 4 on the Shank 1 are attached, whereby they are frictionally engaged in the angular direction with this shank connected is.

Die Spindel 1 dient zum Antrieb eines nicht dargestellten Organes einer Werkzeugmaschine mittels einer Mutter, die ein Ring 5 aufweist. Dieser Ring 5 ist am genannten, nicht dargestellten Organ befestigt und trägt ein Kugellager 6, dessen innerer Ring 7 zwischen die Gewindegänge der Feder 5 ein greift. The spindle 1 is used to drive an organ, not shown a machine tool by means of a nut which has a ring 5. This ring 5 is attached to the said organ, not shown, and carries a ball bearing 6, whose inner ring 7 between the threads of the spring 5 one intervenes.

Die dargestellte Spindel hat den Vorteil, daß sie weitaus billiger herzustellen ist als gewöhnliche Spindeln, deren Gewindegänge aus dem Vollen gearbeitet sind. The spindle shown has the advantage that it is much cheaper can be produced as ordinary spindles, the threads of which are machined from solid are.

Bei der in Fig. 2 dargestellten Variante weist die Spindel einen Schaft 8 auf, auf dem eine Schraubenfeder 9 dreieckigen Querschnittes mit dicht aneinanderliegenden Windungen angebracht ist. Bei dieser Variante ist der Schaft 8 glatt; identische oder ähnLiche Anschläge 4 wie gemäß Fig. 1 hindern die Feder 9 daran, sich um den Schaft 8 zu drehen.-Gemäß Fig. 1 hat die Feder einen runden und gemäß Fig. 2 einen dreieckigen Querschnitt; weitere Querschnittsformen können ebenso gut verwendet werden. In the variant shown in Fig. 2, the spindle has a Shank 8 on which a helical spring 9 triangular cross-section with tight adjacent turns is attached. In this variant, the shaft is 8 smooth; Identical or similar stops 4 as shown in FIG. 1 prevent the spring 9 to rotate around the shaft 8. According to Fig. 1, the spring has a round one and according to FIG. 2, a triangular cross-section; other cross-sectional shapes can can be used just as well.
