Description

Die Erfindung betrifft Bewegungsschrauben mit zwischen den Gewindegängen, eingelegten Rollkörpern, die in einem Käfig geführt werden. Wenn derartige Schrauben senkrecht angeordnet sind und besonders wenn ihr Wälzkörpersystem auf beiden Seiten des Gewindeganges vorgesehen ist, besteht die Gefahr eines Herabsausens des ganzen Systems, falls der Druck zwischen den RollkörpernThe invention relates to movement screws with inserted between the threads Rolling bodies that are guided in a cage. If such screws are perpendicular are arranged and especially if your The rolling element system is provided on both sides of the thread, there is a risk a crash of the whole system if the pressure between the rolling elements

to und der Spindel oder Mutter aufhört. Um diese Gefahr zu beseitigen} liegt gemäß der Erfindung der Käfig an der Spindel oder an der Mutter mit selbsthemmender Reibung an.to and the spindle or nut stops. In order to eliminate this danger} lies according to the Invention of the cage on the spindle or on the nut with self-locking friction at.

In dem Ausführungsbeispiel der Zeichnung ist angenommen, daß jeder Käfig aus zwei spiraligen Blechen 8 zusammengesetzt ist, in denen die Löcher 9 für die Kugeln ausgestanzt sind. In regelmäßigen Abständen sind 'diese beiden Spiralbleche durch Distanznieten miteinander ■ verbunden. Diese Distanzstüeke sind nun am Ende des Käfigs hinter der letzten Kugel durch Federn 10 gebildet, die die Bleche gegen die Gewindegänge der Spindel ι pressen und so den Käfig selbsthemmend machen.In the embodiment of the drawing it is assumed that each cage consists of two spiral sheets 8 is composed, in which the holes 9 punched out for the balls are. At regular intervals, these two spiral sheets are riveted to one another ■ connected. These spacers are now at the end of the cage behind the last ball formed by springs 10, which the metal sheets against the threads of the spindle ι press and so the cage is self-locking do.

Natürlich könnten die Enden des Käfigs auch zwischen die Gänge der Mutter gepreßt werden. Falls der Käfig aus einem, einzigen Flacheisen mit Löchern hergestellt ist, wird man an seinem Ende Blechstreifen mit Gelenken annieten und diese durch die Federn an die Gewindegänge anpressen.Of course, the ends of the cage could also be pressed between the aisles of the mother will. If the cage is made of a single flat iron with holes, is you rivet metal strips with joints at its end and these through the springs press against the threads.
