Description
Einteiliger Blechkäfig für Vierpunktlager Gegenstand der Neuerung ist ein einteiliger, kugelgeführter Blechkäfig für Vierpunktlager, der aus einem mit Taschen versehenen Rohrabschnitt besteht, dessen radiel nach innen oder außen umgebogenen Enden so verformt sind, daß die Kugeln nicht herausfallen können. One-piece sheet metal cage for four-point bearings is the subject of the innovation is a one-piece, ball-guided sheet metal cage for four-point bearings, which consists of a with pockets provided pipe section, whose radiel to the inside or outside bent ends are deformed so that the balls can not fall out.
Die bekannten Käfige für Vierpunktlager sind meist Massivkäfige, die durch spanabhebende Bearbeitung aus vollem Material hergestellt sind. Die Mehrzahl dieser Eäfige, ebeaso-ie die bekannten u-und v-förmigen Blechkäfige, werden auf den Schultern eines Lagerringes geführt, insbesondere bei Lagern, die mit hohen Drehzahlen laufen. Durch die Führung der Käfige auf den Schultern eines Lagerringes entstehen aber zusätzliche Reibungsverluste, die unerwünscht sind.The known cages for four-point bearings are mostly solid cages that are made from solid material by machining. The majority These cages, ebeaso-ie the well-known u- and v-shaped sheet metal cages, are opened out the shoulders of a bearing ring, especially in bearings with high Speeds run. By guiding the cages on the shoulders of a bearing ring however, there are additional friction losses that are undesirable.
Der Käfig nach der Neuerung stellt einen kugelgeführten Blechkäfig dar, der aus einem mit Taschen versehenen Rohrabschnitt besteht, dessen Enden radial nach innen oder außen umgebogen werden, wodurch er einen etwa u-förmigen Querschnitt erhält, der ihm eine große Formsteifigkeit verleiht. Um ein Herausfallen der Kugeln aus dem Käfig zu verhindern, werden die hochgestellten Käfigränder nach innen gebogen. Zur Führung des Käfigs auf den Kugeln werden die ausgestanzten Käfigtaschen, die einen kleineren Durchmesser als die Kugeln besitzen, durch Prägen mit Führungsflächen vergehen.The cage according to the innovation is a ball-guided sheet metal cage which consists of a tubular section provided with pockets, the ends of which are radial be bent inwards or outwards, giving it an approximately U-shaped cross-section receives, which gives it a great rigidity. About the balls falling out To prevent it from getting out of the cage, the raised cage edges are bent inward. To guide the cage on the balls, the punched-out cage pockets, the have a smaller diameter than the balls, by stamping with guide surfaces pass away.
In der Zeichnung ist ein Ausführungsbeispiel der Neuerung dargestellt.In the drawing, an embodiment of the innovation is shown.
Die Abb. 1 zeigt einen querschnitt durch ein Vierpunktlager mit geteiltem Innenring und Abb. 2 einen teilweisen Seitenschnitt des Käfigs. Der Käfig besteht aus einem zylindrischen Mittelstück 1, in dem die Taschen 2 für die Kugeln 3 eingestanzt sind. Die Enden 4 des Käfigs sind radial nach innen umgebogen, wodurch der Käfig seinen u-förmigen uerchnitt erhält. Die Taschen 2 die einen kleineren Durchmesser als die Kugeln 3 besitzen, sind an den Rändern mit Führungsflächen 5 versehen, die durch Prägen mit einer geringfügig größeren Kugel, als die für das Lager vorgesehenen, entstehen. Um zu verhindern, daß die Kugeln bei Entfernung des geteilten Innenrings aus dem Käfig herausfallen, werden die Käfigränder 6 nach innen gebogen.Fig. 1 shows a cross section through a four-point bearing with split Inner ring and Fig. 2 a partial side section of the cage. The cage exists from a cylindrical center piece 1 in which the pockets 2 for the balls 3 are punched are. The ends 4 of the cage are bent radially inward, whereby the cage gets its u-shaped cut. The pockets 2 have a smaller diameter than the balls 3 have, are provided on the edges with guide surfaces 5, the by stamping with a slightly larger ball than the one intended for the bearing, develop. To prevent the balls from falling when the split inner ring is removed fall out of the cage, the cage edges 6 are bent inward.
In Abb. 3 ist ein Käfig fUr ein Vierp@nktlager mit geteiltem Außenring dargestellt. Bei diesem Käfig sind die. Laden 4 radial nach außen umgebogen.Fig. 3 shows a cage for a four-point bearing with a split outer ring shown. With this cage they are. Load 4 bent radially outward.
