Abstract

The centre (6') of the intermediate rollers lies on the centre of the straight line between the two adjoining balls (5) so that the vertical rotational impulse is transferred without any lateral deviation. Bores can be provided in the centre of the intermediate rollers for self-lubricating push-in axles (7) which run with their rounded outer end in the semi-circular trough (8) in the side guide ring (4) only on spot contact. ADVANTAGE - The bearing has reduced maintenance requirements.

Description

Die Erfindung betrifft ein Kugellager mit den Merkmalen des Oberbegriffs von Patentanspruch 1.The invention relates to a ball bearing with the features of Preamble of claim 1.

Das Kugellager, nach bisherigem Stand der Technik, entspricht nicht ganz dem Ideal, denn durch die Reibungsverluste, die das Kugellager bringt, entstehen Belastungen, daß das Lager unbedingt geschmiert werden muß und heiß laufen würde.The ball bearing, according to the current state of the art, corresponds not quite the ideal, because of the friction losses that the Ball bearing brings loads that the bearing necessarily must be lubricated and would run hot.

Durch Versuche und Anwendung der erfindungsgemäßen Technik mit neuen Materialien ist es gelungen ein nahezu wartungsfreies Lager zu schaffen, das mit den oben angeführten Problemen keine Schwierigkeiten hat.By experiments and application of the technique according to the invention new materials have succeeded in being almost maintenance-free To create camp that with the problems listed above none Has difficulties.

Die Vorteile dieser neuen Verbesserung werden in Zukunft gerade bei großen Lagern besonders stark ins Gewicht fallen.The advantages of this new improvement will be just in the future are particularly important for large bearings.

Durch die Anordnung der Zwischenrolle auf dem Mittelpunkt (6′), zwischen den benachbarten Kugeln, wird ihr Impuls senkrecht, in der Weise, auf die Rollen übertragen, daß das Lager völlig entlastet abrollen kann.By arranging the intermediate roller on the center ( 6 '), between the adjacent balls, their momentum is transmitted vertically, in such a way to the rollers that the bearing can roll off completely relieved.

Die Zwischenrollen (6) die mit ihren Steckachsen aus einem selbst­ schmierenden Material, nur auf Punktberührung laufen, können selbst aus diesem Material oder Kunststoff bestehen um eine weichere Übertragung der Kontakte mit den Kugeln zu erreichen.The intermediate rollers ( 6 ), which run with their thru axles made of a self-lubricating material, only on point contact, can even consist of this material or plastic in order to achieve a smoother transfer of the contacts with the balls.

Beide seitlichen Lagerringe (4) werden durch die drei Rollenachsen (7) fixiert. Die Fixierung kann auch mittels Steckverbindung erfolgen, daß somit alle Lagerungen entlastet sind.Both side bearing rings ( 4 ) are fixed by the three roller axes ( 7 ). The fixation can also be done by means of a plug connection, so that all bearings are relieved.

Die Fig. 1 zeigt den Prototyp des erfindungsgemäßen Lagers, das mit einer sehr großen Anzahl von Rollen und Kugeln nahezu reibungslos abläuft. Der Rollenmittelpunkt liegt bei (6′) Fig. 1 shows the prototype of the bearing according to the invention, which runs almost smoothly with a very large number of rollers and balls. The role center is at ( 6 ′)

Die Fig. 2 zeigt das Lager in der Seitenansicht, ohne den Außenring (2). Die konvex nach außen gewölbten Lüfterschaufeln (14) erzeugen einen aerodynamischen Auftrieb der kontinuierlich eine entsprechende Menge an Luft ausbläst und dafür sorgt, daß das Lager nicht heiß laufen kann. Fig. 2 shows the bearing in side view, without the outer ring ( 2 ). The convexly curved fan blades ( 14 ) generate an aerodynamic lift that continuously blows out a corresponding amount of air and ensures that the bearing cannot run hot.

Die Fig. 3 zeigt die Draufsicht eines Großlagers mit mindestens 3 Kugeln (5). Jede Kugel wird von je zwei Abstandsrollen (6) getragen, die vom Innenring (3) achsial geführt werden, daß die Kugeln (5) in den Rillen des Außenlagers (2) frei abrollen können. FIG. 3 shows the top view of a large bearing having at least 3 balls (5). Each ball is carried by two spacer rollers ( 6 ), which are guided axially by the inner ring ( 3 ) so that the balls ( 5 ) can roll freely in the grooves of the outer bearing ( 2 ).

Die Fig. 4 zeigt einen Schnitt durch den oberen Teil des Lagers mit der Lagerung der Abstandsrollen (6), die mit ihren selbstschmierenden Achsen, die halbrund in einer größeren halbrunden Ausnehmung im seitlichen Führungsring (4) gelagert sind. Fig. 4 shows a section through the upper part of the bearing with the bearing of the spacer rollers ( 6 ), which are mounted with their self-lubricating axes, which are semicircular in a larger semicircular recess in the side guide ring ( 4 ).

Die Fig. 5 zeigt eine Variante des Lagers mit durchgehenden Rollenachsen (7) die entweder auf Büchsen (8) oder auf Nadeln (8) in den seitlichen Führungsringen (4) gelagert sind. Denkbar ist auch eine direkte Lagerung der Steckachsen (7) in den seitlichen Führungsringen (4) die auch selbst aus selbstschmierendem Material oder aus Kunststoff sein können. Fig. 5 shows a variant of the bearing with continuous roller axes ( 7 ) which are mounted either on bushes ( 8 ) or on needles ( 8 ) in the side guide rings ( 4 ). It is also conceivable to mount the thru axles ( 7 ) directly in the side guide rings ( 4 ), which can also be made of self-lubricating material or plastic.
