Rollenlager. \ -Roller bearings. \ -

Patentiert im Deutschen Reiche vom 4. August 1917 ab. · Patented in the German Empire on August 4, 1917. ·

Die Erfindung betrifft ein Rollenlager, dessen Rollen aus der Grundform eines Umdrehungsellipsoids symmetrisch geschnittene Scheiben darstellen und zwischen gerillten Außen- und Innenringen laufen. Die Erfindung besteht darin, daß die diametrale Entfernung von Kante zu Kante der Rollen nur um ein geringes Maß größer ist als die Entfernung zwischen den Laufrillen.The invention relates to a roller bearing, the rollers of which have the basic shape of an ellipsoid of revolution represent symmetrically cut slices and run between grooved outer and inner rings. The invention exists in that the diametrical distance from edge to edge of the rollers is only a small one Dimension is greater than the distance between the grooves.

ίο Das Einführen der Rollen zwischen die Laufringe geschieht durch Einschieben und Kippen oder Drehen derselben, wobei im ersteren Falle ein leichter Zwang ausgeübt werden muß, der die Laufringe und die Rollen auf Elastizität beansprucht. Sind die Rollen einmal zwischen die, Laufringe geführt, so ist jedes Kippen beim Laufen ausgeschlossen, weil eben die diametrale Entfernung der Rollenkanten größer als die Entfernung der Laufrillen. ist.ίο The introduction of the rollers between the races happens by pushing in and tilting or turning the same, whereby in the former case a slight force must be exercised, which stresses the races and the rollers for elasticity. Are the roles once guided between the races, any tilting while running is impossible, because it is the diametrical distance of the roller edges is greater than the distance of the grooves. is.

ao In der Zeichnung wird einerseits eine schematische Darstellung wiedergegeben, wie die Scheibenrolle in ein einreihiges Lager eingelegt wird, und andererseits ein Ausführungsbeispiel der Erfindung dargestellt, und zwar zeigenao In the drawing, on the one hand, a schematic Representation reproduced how the disc roller is inserted into a single-row bearing is, and on the other hand, an embodiment of the invention is shown, namely show

Fig. ι bis 3 die Einführung der Rolle in das Lager,Fig. Ι to 3 the introduction of the role in the warehouse,

Fig. 4 das Herumdrehen der Rolle in die Arbeitslage,Fig. 4 the turning of the roll into the working position,

Fig. 5 das Lager mit der Rolle in der Arbeitslage, Fig. 5 shows the bearing with the roller in the working position,

Fig. 6 eine schematische übertriebene Darstellung der zeitweiligen Formveränderung der Außen- und Innenringe im Vergleich mit einer in der Arbeitslage befindlichen Rolle in dem Augenblick, wenn die Rolle in die Arbeitslage verdreht wird.Fig. 6 is a schematic exaggerated representation of the temporary change in shape Outer and inner rings in comparison with a role in the working position in the moment when the roll is twisted into the working position.

Die Laufringe sind mit ι und 2 bezeichnet, ihre Rillen mit 4 und 5, und die Rollen mit 3. Gemäß Fig. I bis 3 ist die Rollendicke so bemessen, daß die Rollen in bekannter Weise in das Lager eingeführt werden können,'. dadurch, daß sie, wie in Fig. 1 gezeigt, umge-• kippt ,zwischen die Laufringe geschoben und hiernach wie in Fig. 2 bis in die in Fig." 3 gezeigte Arbeitslage verdreht werden. Da der Rollenumfang sphärisch ist, kann diese Verdrehung ohne Widerstand erfolgen. Deshalb müssen aber auch die Rollen durch einen Kugelkäfig (in der Zeichnung nicht dargestellt) in ihrer Arbeitslage gehalten werden, weil Gefahr bestünde, daß sie unabsichtlich in die Lage nach Fig. 2 zurückgedreht würden oder doch eine solche Lage erhielten, daß die sphärische Oberfläche aus der in Fig. 3 gezeigten genauen Arbeitslage gelangte. 'The races are denoted by ι and 2, their grooves by 4 and 5, and the rollers by 3. According to Fig. I to 3, the roller thickness is dimensioned so that the rollers in a known manner can be introduced into the warehouse '. in that, as shown in FIG. 1, they tilts, pushed between the races and then as in Fig. 2 to the in Fig. "3 working position shown can be rotated. Since the circumference of the roller is spherical, this rotation can take place without resistance. That's why but the rollers must also be supported by a ball cage (not shown in the drawing) be kept in their working position because there is a risk that they will be unintentionally into the Position of Fig. 2 would be rotated back or received such a position that the spherical Surface came from the exact working position shown in Fig. 3. '

Nach der Erfindung besteht, wie in Fig. 4 und 5 dargestellt, jede Rolle aus einer Zone eines Umdrehungsellipsoids solcher Höhe oder Dicke, daß die Entfernung von Ecke zu Ecke in der Projektion, die die Rolle in einer Achsialfläche des Lagers bildet, ein wenig größer ist wie die Kleinachse des Ellipsoids oder, was dasselbe bedeutet, wie die Entfernung zwischen den Böden der Rillen 4 und 5. Diese Maße sind in Fig. 6 mit 6 und 7 bezeichnet. Beim Umkippen der Kugeln 3 in die Arbeitslage ist es hier wegen des Maßunterschiedes erforderlich, etwas Gewalt zur Erzwingung derAccording to the invention, as shown in FIGS. 4 and 5, each roller consists of a zone an ellipsoid of revolution of such height or thickness that the distance from corner to corner a little larger in the projection that the roller forms in an axial surface of the bearing is like the minor axis of the ellipsoid or, which means the same thing, the distance between the bottoms of the grooves 4 and 5. These dimensions are denoted by 6 and 7 in FIG. When the balls 3 tip over into the working position, it is here because of the dimensional difference required some force to enforce the

zeitweiligen Formveränderung oder die Spreizung . der Laufringe anzuwenden. Die Größe dieser Formveränderung ist in Fig. 6 schematisch dargestellt. temporary change in shape or spreading. of the races. The size this change in shape is shown schematically in FIG.

Die Ringe ι und 2 sind um soviel entfernt, wie die Eckenentfernung 6 beträgt. Das Ellipsoid ist mit strichpunktierten Linien angedeutet. Nach der Erfindung darf die Formveränderung der Ringe 1, 2 oder der Rollennicht so groß sein, daß die auftretende Beanspruchung die Elastizitätsgrenze des Stoffes übersteigt. Wird die Beanspruchung unter diesem Maß gehalten, so ist die Formveränderung nur vorübergehend, und Ringe und Rollen nehmen sofort die vorgesehene genaue Form wieder an, sobald letztere in die normale Lage verdreht worden sind. Die Bedingung dieser kleinen Formveränderung wird dadurch erfüllt, daß die Dicke der Rolle oder die Entfernung zwischen ihren abgeplatteten Seitenflächen innerhalb eines gewissen Maximalwertes gehalten wird, der sich aus den Proportionen des Ellipsoids ergibt.Rings ι and 2 are so far removed how the corner distance is 6. The ellipsoid is indicated with dot-dash lines. According to the invention, the change in shape of the rings 1, 2 or the rollers must not be so great that the stress that occurs exceeds the elastic limit of the fabric exceeds. If the stress is kept below this level, the change in shape is only temporarily, and rings and rollers immediately take the intended exact Shape again as soon as the latter have been twisted into the normal position. The condition this small change in shape is met by the fact that the thickness of the roll or the distance between their flattened side faces within a certain maximum value which results from the proportions of the ellipsoid.
