Kugelgewindetrieb mit zwei gehäusefreien vorgespannten KugelgewindemutternBall screw drive with two housing-free preloaded ball screw nuts
Die Erfindung bezieht sich gemäß dem Oberbegriff des Schutzanspruchs auf einen Kugelgewindetrieb, in dem die Kugelgewindespindel in der Zone zwischen zwei vorgespannten Kugelgewindemuttern auf Zugspannung belastet ist.The invention relates according to the preamble of the claim to a ball screw in which the ball screw spindle is subjected to tensile stress in the zone between two preloaded ball screw nuts is.
In der dem Fachmann bekannten Literatur sind die vielfältigen Vorspannmöglichkeiten von Kugelgewindenr.vttern ausführlich beschrieben.In the literature known to the person skilled in the art, the diverse preloading possibilities of ball screw threads described in detail.
Das Ziel der vorliegenden Erfindung ist ein Kugelgewindetrieb sehr hoher Steifigkeit mit zwei vorgespannten gehäuselosen Kugelgewindemuttern. Erreicht wird dieses Ziel gemäß dem Kennzeichenteil des Schutzanspruchs durch ein Minimum an Bauteilen, so daß der Kraftfluß in beiden Richtungsmöglichkeiten unmittelbar von einer Mutter auf die andere Mutter wirkt.The aim of the present invention is a ball screw very high rigidity with two preloaded ball screw nuts without a housing. Is achieved this goal according to the characterizing part of the protection claim by a minimum of components, so that the power flow acts in both directions directly from one mother to the other mother.

The thickness of this support disk 10 corresponds to the axial backlash between the spindle 3 and nuts 1 and 2. At the location of the feather key 5, the support disk 10 has a corresponding recess.
Vermittels der beiden Vorspannschrauben 8 wird die Mutter 2 gegenüber der Mutter 1 so weit verdreht und fixiert, daß das bereits durch die Stützscheibe verringerte Flankenspiel sehr feinfühlig gegen Null gebracht wird.The nut 2 is rotated so far with respect to the nut 1 by means of the two pretensioning screws 8 and fixes that the backlash, which has already been reduced by the support disc, is very sensitive to zero is brought.
Diese Montage- und Justierarbeit verläuft sehr einfach und schnell, da das axiale Flankenspiel - vermittels Schieblehre meßbar - hinreichend genau die Dicke der Stützscheibe ergibt und mit den Vorspannschrauben der notwendige Anpreßdruck feinfühlig reguliert und fixiert werden kann.This assembly and adjustment work is very easy and quick, since the axial backlash - measurable by means of calipers - is sufficiently accurate The thickness of the support disc results and the necessary contact pressure is sensitively regulated with the pre-tensioning screws and can be fixed.
Wie aus Fig. 1 zu erkennen ist, wirken die möglichen beiden Kraftrichtungen P1 und P2 jeweils nur über die Stützscheibe 10 zwischen den Muttern 1 und 2.As can be seen from Fig. 1, the possible two directions of force P1 and P2 act only via the Support washer 10 between nuts 1 and 2.
