Description

Kugellagerung für Schraubengetriebe mit geteilter Mutter. Die Erfindung betrifft Kugellagerungen für Schraubengetriebe mit geteilter Mutter, bei denen die Kugeln durch ein den .Gewindegängen entsprechend schraubenförmig verlaufendes Band gehalten werden. Um ein Herausfallen der Kugeln beim Öffnen der Mutter zu vermeiden, werden gemäß der Erfindung die Kugeln eines jeden halben Gewindeganges durch ein mit den Enden an der Mutterhälfte angeordnetes, die Kiugeln umgreifendes, verhältnismäßig schmales Band gehalten, das der Oberfläche der Kugeln und zwischen diesen der Oberfläche der Mutterhälfte entsprechend geformt ist.Ball bearing for screw gears with split nut. The invention concerns ball bearings for screw gears with split nut, where the Balls through a band running in a helical manner corresponding to the threads being held. To prevent the balls from falling out when opening the nut, according to the invention, the balls of each half thread turn through a arranged with the ends on the nut half, encompassing the balls, relatively narrow band held that of the surface of the balls and between them the surface the nut half is shaped accordingly.

Eine beispielsweise Ausführungsform der Kugellagerung gemäß der Erfindung ist auf der Zeichnung dargestellt. Abb. i zeigt einen senkrechten Schnitt durch ein Leitspindelmutterschloß einer Drehbank, wobei die bekannten, die beiden Mutterhälften gegeneinander bewegenden Schloßteile fortgelassen sind. Abb 2 ist eine Draufsicht auf die untere Mutterhälfte.An example embodiment of the ball bearing according to the invention is shown on the drawing. Fig. I shows a vertical section through a lead screw nut lock of a lathe, the known, the two nut halves lock parts moving against each other are omitted. Figure 2 is a plan view on the lower half of the nut.

i ist die Leitspindel, 2 sind die Gänge der Leitspindel, 3 ist die untere Mutterhälfte, i i ist die obere Mutterhälfte, 12 ist das bekannte Schloß, in welchem die gehärteten Mutterhälften 3 und i i ruhen. 5 sind die gehärteten Keile, 7 sind die Kugeln, 13 ist das dem Verlaufe der Kugeln 7 angepaßte Band, welches zweckmäßig aus Stahl besteht und mit den Enden an den Mutterflächen 15 durch die Leisten 14 und die Schrauben 16 befestigt wird.i is the lead screw, 2 are the threads of the lead screw, 3 is the lower nut half, ii is the upper nut half, 12 is the well-known lock in which the hardened nut halves 3 and ii rest. 5 are the hardened wedges, 7 are the balls, 13 is the band adapted to the course of the balls 7, which is suitably made of steel and is fastened with the ends to the nut surfaces 15 by the strips 14 and the screws 16.
