Description
Die Erfindung betrifft eine Schraubenwinde und besteht darin, daß das Schraubengewinde der Spindel an seinem äußeren Umfang mit Zähnen versehen ist, in die eine Schnecke oder eine andere Antriebs- oder Vorschalteinrichtung eingreift, wodurch ein Drehen der Spindel und damit ein Anheben der Pratze bewirkt wird. Die bisher bekannten Vorrichtungen dieser Art bedienen sich, um dieThe invention relates to a screw jack and consists in that the screw thread the spindle is provided with teeth on its outer circumference, into which a worm or other drive or ballast device engages, whereby a rotation of the spindle and thus a lifting of the claw is effected. The previously known devices of this kind avail themselves to the
to Spindel aus der Mutter heraus oder hereinzuschrauben, eines Werkzeuges, durch das entweder die Spindel oder deren' Mutter gedreht wird. Im ersten Fall mußte das Werkzeug die Hubbewegung der Spindel mitmachen, im zweiten Fall mußte eine besondere Mutter, die ihrerseits wieder auf einem Bock oder auf einer entsprechenden Unterlage ruht, vorgesehen werden. Beiden Antriebsarten haften gewisse Nachteile an, die durch vorliegende Erfindung vermieden werden. Die Mutter und der Bock bilden ein untrennbares Ganzes. In dem Muttergewinde wird das Gewinde der Schraubenspindel geführt, das mit Zähnen versehen ist und somit die Zahnräderzwischengetriebe in sich vereinigt, die bisher Anwendung fanden, falls indirekt der Antrieb der Mutter oder der Spindel durch Zahnrad- und Schneckenübertragung bewirkt wurde. Die vorliegende Erfindung macht somit das Anbringen ; ! von besonderen mit der Spindel oder der j Mutter verbundenen Zahnrädern überflüssig.to screw the spindle out or in of the nut, a tool by which either the spindle or its nut is turned. In the first case the tool had to follow the stroke movement of the spindle, in the second case a special nut had to be provided, which in turn rests on a trestle or on a corresponding base. Both types of drive have certain disadvantages which are avoided by the present invention. The mother and the buck form an inseparable whole. In the nut thread, the thread of the screw spindle is guided, which is provided with teeth and thus combines the intermediate gear transmissions that have been used up to now if the drive of the nut or the spindle was effected indirectly by gear and worm transmission. The present invention thus makes the attachment; ! there is no need for special gears connected to the spindle or the nut.
Der Antrieb. erfolgt zweckmäßig durch eine Schnecke die in geeigneter Weise an der Mutter bzw. dem Bock der Schraubenwinde befestigt wird.The drive. is expediently carried out by a screw which is suitably attached to the Nut or the bracket of the screw jack is attached.
Auf der Zeichnung ist eine Ausführungsform dargestellt.An embodiment is shown in the drawing.
Fig. ι zeigt, teilweise im Schnitt und teil-Fig. Ι shows, partly in section and partly
: weise in Ansicht, eine Gewindespindel und Mütter,: wise in view, a threaded spindle and nuts,
Fig. 2 einen 'Querschnitt der Fig. 1 der Linie A-B. FIG. 2 shows a cross section of FIG. 1 along the line AB.
Der Gewindegang der flachgängigen Gewindespindel α ist mit Zähnen i versehen, so daß der Gewindegang im Grunde genommen eine lange Zahnstange bildet. Die Mutter c trägt in zwei Lagern d und e eine Schnecke f. Diese greift in die Verzahnung der Gewindespindel ein, und durch Drehung der Schnecke wird die Spindel heraus- bzw. hereingeschraubt.The thread of the flat threaded spindle α is provided with teeth i , so that the thread basically forms a long rack. The nut c carries a worm f in two bearings d and e . This engages in the toothing of the threaded spindle, and by turning the worm the spindle is screwed in or out.
