KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Erfindung bezieht sich auf Lager für elektrische Meßgeräte mit aufrechtstehender, auf einer Stahlkugel aufruhender Spindel und bezweckt, bei derartigen Lageranordnungen eine doppelseitige Ausnutzung des Lagers herbeizuführen. The invention relates to bearings for electrical measuring devices with upright, on a steel ball resting spindle and is intended for such bearing arrangements to bring about a double-sided utilization of the bearing.
Dies wird durch allmählich festere magnetische Kupplung der Kugel mit der umlaufenden Spindel infolge Magnetisierung derselbenThis is achieved by gradually tightening the magnetic coupling of the ball with the rotating one Spindle due to magnetization of the same
ίο durch eine stromführende Spule bewirkt. Die Kugel dreht sich bei fester Kupplung mit der umlaufenden Spindel auf dem festen Unterteil des Lagers, während bei nicht vorhandener oder nur geringer Magnetisierung der Spindel die Kugel fest im Unterteil ruht und die Spindel sich auf der Kugel dreht. Dadurch ist eine doppelseitige Ausnutzung des Lagers insofern gewährleistet, als die obere Lagerhälfte für die untere Meßzone, welche geringere Werte und damit auch geringe oder gar keine magnetischen Kupplungskräfte aufweist, die untere Lagerhälfte für die obere Meßzone mit den großen Werten und der großen Magnetisierung vorbehalten bleibt. Zweckmäßig wird dabei der Krümmungsradius der Auflagerfläche der Spindel bedeutend größer gewählt als wie derjenige der Kugel, damit die bei Benutzung der oberen Lagerhälfte vorhandene geringe Eigentriebkraft der Spindel einen infolge kleinster Auflagedruckfläche minimalen Reibungswiderstand vorfindet, während der Krümmungsradius des festen Lagerunterteiles nur wenig größer zu sein braucht als derjenige der Kugel, da bei Benutzung der unteren Lagerhälfte auch die Eigentriebkraft der Spindel größer ist und somit auch ein größerer Reibungswiderstand leicht überwunden wird.ίο caused by a live coil. the With a fixed coupling, the ball rotates with the rotating spindle on the fixed lower part of the bearing, while in the absence of or only low magnetization of the spindle the ball rests firmly in the lower part and the spindle rotates on the ball. Through this a double-sided utilization of the bearing is guaranteed insofar as the upper half of the bearing for the lower measuring zone, which has lower values and thus also little or none at all Has magnetic coupling forces, the lower half of the bearing for the upper measuring zone with is reserved for the large values and the large magnetization. Will be expedient while the radius of curvature of the bearing surface of the spindle is chosen to be significantly larger than how that of the ball, so that the small one that is present when the upper half of the bearing is used The spindle's own driving force results in minimal frictional resistance as a result of the smallest contact pressure surface finds, while the radius of curvature of the fixed bearing lower part needs to be only slightly larger than that the ball, because when the lower half of the bearing is used, the self-propelling force of the Spindle is larger and thus a greater frictional resistance can easily be overcome will.
Die Zeichnung stellt die Ausführung der Lagerung schematisch dar. 1 bedeutet die umlaufende Spindel eines Meßinstrumentes, die frei drehbar innerhalb einer stromdurchflossenen Spule 2 gelagert ist und, da aus Eisen angefertigt, einen Elektromagnetkern bildet. 3 ist das feste Unterteil aus antimagnetischem Material, 4 eine harte, polierte Stahlkugel, 5 eine nach innen gewölbte Edelsteinpfanne, welche fest in das Unterteil 3 eingelassen ist, 6 die zwecks Verringerung der Auflagedruckfläche sehr flach gewölbte Edelsteinpfanne im unteren Spindelende.The drawing shows the execution of the storage schematically. 1 means the revolving spindle of a measuring instrument, which is freely rotatable within a current-carrying Coil 2 is mounted and, since made of iron, forms an electromagnet core. 3 is the fixed lower part made of antimagnetic material, 4 is a hard, polished steel ball, 5 an inwardly curved gemstone pan, which is firmly embedded in the lower part 3 6 is the gemstone pan, which is curved very flat in order to reduce the contact pressure area in the lower end of the spindle.
