Abstract

The ball discs are mathematical ball layers whose radii of the restricting circles are equal size. During assembly of the bearing a large number of rolling bodies can be installed without filler grooves or divided rings. One or both restricting circular faces of the discs for guiding through a cage are not flat. The discs can be axially drilled through. USE/ADVANTAGE - Radial rolling bearing assembly is for casters and support rollers and is easy to assemble.

Description

Die Erfindung betrifft ein Radial-Wälzlager, dessen Rollkörper zum Teil oder ausschließlich aus Kugelscheiben bestehen.The invention relates to a radial roller bearing, the rolling element of which is partly or consist exclusively of spherical washers.

Kugelscheiben sind Kugelschichten, bei denen die Radien der Begrenzungs­ kreise gleich groß sind.Spherical washers are spherical layers in which the radii of the boundary circles are the same size.

Bei der Herstellung von Radial-Kugellagern, ist die maximal einbaubare Anzahl von Kugeln, durch die Abmessungen von Innen- und Außenring, und den Kugeldurchmesser festgelegt.When producing radial ball bearings, the maximum that can be installed Number of balls, by the dimensions of the inner and outer ring, and the Ball diameter set.

Um diese Anzahl, und damit die Tragfähigkeit des Lagers zu erhöhen, gibt es die Möglichkeit eine Füllnut anzubringen, wodurch das Lager nur noch geringe Axialkräfte aufnehmen kann. Des weiteren gibt es die Möglichkeit, Ringteilungen oder Ringsprengungen vorzunehmen, was neben hohem Herstel­ lungsaufwand noch zu weiteren Nachteilen führt (z. B. niedrige Drehzahl­ grenze, für Ölschmierung ungeeignet).In order to increase this number, and thus the bearing capacity of the bearing it is possible to add a filling groove, which only makes the bearing can absorb low axial forces. Furthermore there is the possibility To make ring divisions or ring explosions, what next to high manufac still leads to further disadvantages (e.g. low speed limit, unsuitable for oil lubrication).

Der Einsatz von Kugelscheiben ermöglicht das Einbauen einer größeren Anzahl von Rollkörpern, ohne die o.g. Nachteile. Dabei können bestimmte Lagertypen mit einer geringeren Breite als üblich, hergestellt werden.The use of spherical washers enables the installation of a larger one Number of rolling elements, without the above Disadvantage. Certain Bearing types with a smaller width than usual are manufactured.

(Abb. 1) Beim Befüllen des Lagers mit Kugelscheiben (1), werden diese axial zum Lager, zwischen Innenring (2) und Außenring (3) eingeführt. Wenn sich ihr Mittelpunkt auf der Höhe der Rollbahnenachse befindet, werden sie um 90° gedreht, sodaß ihre Kugeloberfläche in den Rollbahnen abrollen kann.( Fig. 1) When filling the bearing with spherical washers ( 1 ), these are inserted axially to the bearing, between the inner ring ( 2 ) and the outer ring ( 3 ). If their center is at the level of the runway axis, they are rotated by 90 ° so that their spherical surface can roll in the runways.

Um die Kugelscheiben in ihren Positionen zu halten, werden sie von einem Käfig geführt.In order to keep the spherical washers in their positions, one of them Cage led.

Nach diesem System lassen sich beispielhaft, Rillenkugellager herstellen, die abwechselnd Kugeln und Kugelscheiben aufweisen (Abb. 2a).This system can be used, for example, to manufacture deep groove ball bearings with alternating balls and spherical disks ( Fig. 2a).

Des weiteren lassen sich Wälzlager mit Rillenkugellager-Charakter her­ stellen, dessen Rollkörper ausschließlich Kugelscheiben sind, und dadurch zusätzlich eine geringe Breite des Lagers ermöglichen (Abb. 2b). In addition, rolling bearings with a deep groove ball bearing character can be manufactured, the rolling elements of which are exclusively spherical washers, and thus also allow the bearing to be narrow ( Fig. 2b).

Weiterhin sind folgende Ausführungen, beispielhaft, möglich:The following examples are also possible:

  • - Kugelscheibenlager in mehrreihiger Ausführung mit geringer Breite (Abb. 2c).- Ball disc bearings in multiple rows with a narrow width ( Fig. 2c).
  • - Schräg-Kugelscheibenlager (auch mit Kugeln und Kugelscheiben abwech­ selnd möglich), mit großer Tragfähigkeit (Abb. 2d).- Angular contact spherical disk bearings (alternating with balls and spherical disks also possible), with high load-bearing capacity ( Fig. 2d).
  • - Zweireihige Schräg-Kugelscheibenlager (auch mit Kugeln und Kugel­ scheiben abwechselnd möglich), mit großer Tragfähigkeit (Abb. 2e).- Double row angular contact spherical disc bearings (alternatively also possible with spheres and spherical discs), with high load-bearing capacity ( Fig. 2e).
  • - Einreihige Schräg-Kugelscheibenlager für die Aufnahme zweiseitig wirkender Axialkräfte (mit der Wirkung eines Vier-Punkt-Lagers), indem die Kugelscheiben, in axialer Richtung abwechselnd, schräg ge­ stellt sind (Abb. 2f).- Single-row angular contact spherical disk bearings for absorbing double-sided axial forces (with the effect of a four-point bearing) by tilting the spherical disks alternately in the axial direction ( Fig. 2f).

Für eine optimale Führung durch den Käfig (4) kann, wie in Abb. 3 bei­ spielhaft dargestellt, eine der Flachseiten der Kugelscheibe, ballig oder ähnlich, ausgeführt werden.For optimal guidance through the cage ( 4 ), one of the flat sides of the spherical disk, spherical or similar, can be designed, as shown in Fig. 3 for example.
