Description
Rollenlager. Rollenlager mit zwischen Käfigringen gehaltenen und seitlich schwingbaren Rollen -sind an sich bekannt. Das Bestreben geht dahin, den ballig gestalteten Rollen zu ermöglichen, sich selbst in ihrer Laufspur und mit Bezug auf die Belastung einzustellen, derart, daB sie selbstführend werden, wenn sie sich mit der, ihnen zukommenden Geschwindigkeit drehen. Die bisher bekannten Rollenlager dieser Art erfüllen ihre Aufgabe nicht ganz. So ist bei einer Ausführungsform ein Ausschwingen in einer senkrecht zur geometrischen Achse liegenden Ebene dadurch ermöglicht, daB die Rollen durch Schneiden an den Käfigringen zentral gehalten werden, die aber ein anderes Ausschwingen als um diese Schneiden nicht zulassen. Bei anderen Ausführungsformen, bei denen diese Schneiden fortfallen, ist der Nachteil vorhanden, daß die Rollen auch in achsialer Richtung keinerlei Führung erhalten. Nach vorliegender Erfindung werden die Rollen derart geführt, :daß unter Beibehaltung einer freien Ausschwingungsmöglichkeit die achsiale Verschiebung innerhalb der Käfigringe ausgeschlossen ist. Dies kann in der Weise bewirkt werden, daß die Stirnflächen der Rollen selbst konvex gestaltet sind und mit der dadurch erzielten mittleren Erhöhung sich an der Innenfläche der Käfigringe abwälzen. Die - Verbindungsbolzen der beiden Käfigringe können als Rollenwellen verwendet werden, in welchem Falle diese mittlere Verdickungen aufweisen können, um die die Rollen schaukeln können. Zweckmäßig erhalten dann die Bohrungen der Rollen eine mittlere, kugelig geformte Rille, die annähernd der konvexen Verdickung der Lagerbolzen entspricht und dieser eine Stütze verleiht.Roller bearings. Roller bearing with held between cage rings and laterally swingable rollers are known per se. The endeavor goes to the convex designed roles to enable themselves in their running lane and with respect to adjust the load so that they become self-guiding when they become turn at the speed that suits them. The previously known roller bearings these types do not quite do their job. So in one embodiment is a Swinging out in a plane perpendicular to the geometric axis as a result enables the rollers to be held centrally by cutting on the cage rings, but they do not have a different swing than around these cutting edges allow. In other embodiments in which these cutting edges are omitted, the disadvantage is present that the roles do not receive any guidance in the axial direction. According to the present invention, the roles are guided in such a way: that while maintaining a free oscillation possibility the axial displacement within the cage rings is excluded. This can be done in such a way that the end faces the roles themselves are designed to be convex and with the medium achieved thereby Elevation roll on the inner surface of the cage rings. The - connecting bolts of the two cage rings can be used as roller shafts, in which case these can have middle thickenings around which the rollers can swing. The bores of the rollers are then expediently given a central, spherical shape Groove, which approximately corresponds to the convex thickening of the bearing pin and this gives a prop.
Die Abb. 1, 2 und 3 zeigen Querschnitte von Käfigringen mit Rollen in drei verschiedenen Ausführungsformen, und,die Abb. 4, 5, 6 und 7 zeigen Schnitte von Rollenlagern mit weiteren Ausführungsformen der Ringe bzw. Rollen.Figs. 1, 2 and 3 show cross sections of cage rings with rollers in three different embodiments, and, Figs. 4, 5, 6 and 7 show sections of roller bearings with further embodiments of the rings or rollers.
Bei sämtlichen Ausführungsformen sind die Rollen a zwischen zwei Käfigringen d gelagert und vermögen an den inneren und äußeren Laufringen b und c sich abzurollen.In all embodiments, the rollers a are between two cage rings d and are able to roll on the inner and outer races b and c.
Bei der in Abb. i gezeigten Ausführungsfortn sind an den Käfigringen d Vorsprünge e vorgesehen, die dadurch erzeugt sein können, daß die Ringe Eindrücke von der anderen Seite erhalten.In the embodiment shown in Fig. I, there are on the cage rings d projections e provided, which can be produced by the fact that the rings impressions received from the other side.
Sollen die Vorsprünge anstatt an den Ringen d an den Rollen vorgesehen sein, so ist es nicht erforderlich, daß zu diesem Zweck besondere Achsen vorgesehen sind. So können die Rollen selbst an ihren Stirnflächen kegelförmige Erhöhungen in (Abb. 2) oder konvexe Abrundungen n (Abb. 3) erhalten, wodurch die Rollen gegen die Ringe sich ab-«,älzen können, um die gewünschte Einstellung zu erzielen, ohne achsial sich verschieben zu können.Should the projections be provided on the rollers instead of on the rings d it is not necessary that special axles be provided for this purpose are. So the rollers can even have conical elevations on their end faces obtained in (Fig. 2) or convex fillets n (Fig. 3), causing the rollers against the rings roll off - «, can roll to achieve the desired setting without to be able to move axially.
Die Rollen können auch, wie in den Abb. 4 bis 7 dargestellt ist, eine mittlere öffnung oder Durchbohrung e' erhalten, durch die ein Bolzen oder eine Welle f' o. dgl. durchgezogen ist, die die beiden Ringe miteinander verbindet. Der Bolzen f' bzw. die üffnung e' kann so gestaltet sein, daß durch diese Teile die gewünschte, nach allen Richtungen mögliche Einstellbarkeit erreicht werden kann, wobei ein Punktkontakt oder ein kreisförmiger oder elliptischer Kontakt, je nach der Belastung entsteht.The roles can also, as shown in Figs. 4 to 7, a middle opening or perforation e 'obtained through which a bolt or shaft f 'o. The like. Is drawn through, which connects the two rings with one another. The bolt f 'or the opening e' can be designed so that the desired, Adjustability possible in all directions can be achieved, with a point contact or a circular or elliptical contact, depending on the load.
Bei den in Abb. 5, 6 und 7 gezeigten Ausführungsformen ist die Durchbohrung etwa in der Mitte zu einer Ringnut G ausgebildet, in die ein verdickter Teil des Bolzens eingreift, wodurch ein guter Halt und eine genaue Einstellbarkeit der Rolle ermöglicht wird. Bei den Ausführungsformen Abb. 5 und 6 ist die Durchbohrung der Rolle durch eine Hülse H ausgebuchst, und zwar bei der Konstruktion Abb. 6 auf die ganze Länge der Bohrung und bei der Konstruktion Abb. 5 zur Hälfte, so daß die Hülse mit ihrem inneren Ende sich gegen die Verdickung stützt.In the embodiments shown in Figs. 5, 6 and 7, the through hole is formed approximately in the middle to form an annular groove G into which a thickened part of the Bolt engages, creating a good grip and precise adjustability of the role is made possible. In the embodiments Fig. 5 and 6, the through hole is the Role bulged by a sleeve H, in the construction Fig. 6 on the entire length of the hole and in the construction Fig. 5 halfway, so that the sleeve with its inner end is supported against the thickening.
Bei der in Abb. 7 gezeigten Ausführungsform wird,das gewünschte Ergebnis .dadurch erzielt, daß die achsiale Durchbohrung e' in der Rolle nach beiden Enden hin sich erweitert, im übrigen ist die Wandung der Durchbohrung kugelförmig ausgehöhlt zur Aufnahme des kugelförmigen Teiles des Bolzens oder der Welle. Die weite Öffnung auf jeder Seite der Rolle ermöglicht das Einführen des verdickten Teils des Bolzens, zu welchem Zweck die kugelförmige Verdickung des . Bolzens mit zwei einander gegenüberliegenden, abgeflachten Teilen versehen sein kann.In the embodiment shown in Fig. 7, the desired result is achieved . Achieved in that the axial through hole e 'in the roller to both ends expands towards itself, otherwise the wall of the through-hole is hollowed out spherically to accommodate the spherical part of the bolt or the shaft. The wide opening on each side of the roller allows the insertion of the thickened part of the bolt, for what purpose the spherical thickening of the. Bolt with two opposite, flattened parts can be provided.
