Description

Kugelkäfig aus Kunststoff Die Erfindung bezieht sich auf einen in Segmente unterteilten, elastischen Kugelkäfig aus Kunststoff, z. B. aus mit ausgehärtetem Kunststoff getränkten Gewebe, für Axialkugellager, der im Bereich jeder jeweils eine Kugel aufnehmenden Aussparung mit einem zur Aussparung führenden, radial und axial durchgehenden Schlitz versehen ist.Ball cage made of plastic The invention relates to an in Segments subdivided, elastic ball cage made of plastic, e.g. B. from with cured Plastic soaked fabric, for axial ball bearings, in the area of each one a ball receiving recess with a leading to the recess, radial and axially continuous slot is provided.

Kugelkäfige aus Kunststoff sind an sich bereits bekannt. Der Werkstoff dieser bekannten Käfige besitzt zwar eine gewisse Eastizität, diese genügt jedoch nicht, um ein einwandfreies Abrollen der Kugeln, vor allem bei ungleichmäßiger Belastung des Lagers, zu sichern. Dies trifft auch für einen bekannten Kugelkäfig zu, bei dem als Abstandhalter ein Kunststoffstreifen mit Aussparungen für die Kugeln benutz wird, die sämtlich einen Schlitz nach der gleichen Streifenseite aufweisen.Ball cages made of plastic are already known per se. The material this well-known cage has a certain eastity, but this is sufficient not to ensure that the balls roll smoothly, especially when the load is uneven of the camp to secure. This also applies to a known ball cage use a plastic strip with recesses for the balls as a spacer which all have a slit on the same side of the strip.

Die Erfindung schlägt vor, den Kugelkäfig in Umfangrichtung so elastisch auszubilden, daß er Unregelmäßigkeiten im Ablauf der Kugeln auffängt. Diese Unregelmäßigkeiten entstehen z. B., wenn ein Axiallager über seinen Umfang ungleich belastet wird, so daß die Kugeln die Tendenz zeigen, an einer Stelle näher zusammenzulaufen und an anderer größere Abstände zu bilden, wodurch der Drehwiderstand erhöht wird. Erfindungsgemäß kann der Kugelkäfig diesen zusammengedrängten Kugeln folgen und sie durch die ihm verliehene Elastizität wieder zurückführen. Zu diesem Zweck sind erfindungsgemäß die Schlitze abwechselnd vom Käfigaußenmantel und vom Käfiginnenmantel her zu den Aussparungen geführt.The invention proposes that the ball cage be so elastic in the circumferential direction to train that he catches irregularities in the course of the balls. These irregularities arise z. B., if an axial bearing is loaded unevenly over its circumference, so that the balls have a tendency to converge at one point and to form larger distances at others, whereby the rotational resistance is increased. According to the invention the ball cage can follow these crowded balls and pass them through it restore the elasticity that has been imparted. For this purpose are according to the invention the slots alternate from the outer shell of the cage and the inner shell of the cage to the Recesses led.

Versuche haben ergeben, daß durch Einsatz von geschlitzten Käfigseginenten gemäß der Erfindung z. B. ein Spitzendrehmoment von 26 mkg auf eine Spitze von 13 mkg heruntergedrückt wird.Tests have shown that by using slotted cage segments according to the invention, for. B. a peak torque of 26 mkg is pushed down to a peak of 13 mkg.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Es zeigt Ab b. 1 eine Draufsicht auf die aneinanderstoßenden Enden zweier gemäß der Erfindung geschlitzter Käfigsegmente, A b b. 2 einen Schnitt nach der Linie U-II der Abb. 1, Ab b. 3 eine Draufsicht auf einen Käfigring aus fünf Segmenten, geschlitzt gemäß der Erfindung.An exemplary embodiment of the invention is shown in the drawing. It shows Ab b. 1 shows a plan view of the abutting ends of two cage segments slotted according to the invention, A b b. 2 a section along the line U-II of Fig. 1, Ab b. 3 shows a plan view of a cage ring made of five segments, slotted according to the invention.

In den Abbildungen bezeichnet 1 die Käfigsegmente mit den Lagerungen 2 für die Wälzkörper. Von diesen aus, abwechselnd nach innen und außen, verlaufen die Schlitze 3. In the figures, 1 denotes the cage segments with the bearings 2 for the rolling elements. The slots 3 run from these, alternately inwards and outwards.
