Description

Die Erfindung betrifft ein Kugellager mit mehreren von einem Käfig gehaltenen Trennkugeln zwischen den Tragkugeln, wobei mindestens drei Trennkugeln in einem scheibenförmigen Halter zusammengefaßt und jeweils zwischen zwei Tragkugeln gesetzt werden. Sie bezweckt die Schaffung eines mit geringster Reibung laufenden Kugellagers, insbesondere für Kugellager mit großen Abmessungen. The invention relates to a ball bearing with a plurality of separating balls held by a cage between the supporting balls, with at least three separating balls in a disk-shaped Holders combined and placed between two support balls. Its purpose is to create one with the least Friction-running ball bearings, especially for ball bearings with large dimensions.

Bei käfigloeen Kugellagern mit Trennkugeln hat man bisher die Trennkugeln nur um wenige Zehntelmillkneter kleiner gemacht als die Tragkugeln. Infolgedessen verlieren derartige Lager verhältnismäßig viel an ihrer Tragfähigkeit. Der Versuch, die Tragfähigkeit käfigloser Lager dadurch zu vergrößern, daß man statt der großen Trennkugeln schmale Zwischenscheiben oder eine in einer schmalen Scheibe gelagerte kleine Trennkugel benutzt, hat meist eine Vergrößerung des Reibungswiderstandes des Lagers u.nd evtl. Verklemmungen zur Folge.In the case of cage-free ball bearings with separating balls, you only have the separating balls so far Made a few tenths of a mill kneader smaller than the support balls. As a result, lose such bearings are relatively much in terms of their load-bearing capacity. The attempt to increase the load-bearing capacity of cage-less bearings enlarge that instead of the large separating balls, narrow spacers or a Used small separating ball stored in a narrow disk, usually has an enlargement the frictional resistance of the bearing and possibly jamming.

Um bei Rollenlagern solche Trennkugeln zwischen den Tragrollen einsetzen zu können, wurde vorgeschlagen, die Tragrollen um das Maß der Trennkugeln abzusetzen, was aber die Tragfähigkeit des Rollenlagers verringert. Ebenso ist es bekannt, bei mehrreihigen Kugellagern zwischen vier beieinander liegenden Tragkugeln jeweils eine nahezu gleich große Trennkugel zu setzen.In order to be able to use such separating balls between the support rollers in roller bearings, it was suggested to set down the support rollers by the size of the separating balls, but this reduces the load-bearing capacity of the roller bearing. It is also known, in the case of multi-row ball bearings, almost one in each case between four support balls lying next to one another to set the same size separating ball.

Die Erfindung ist ein Kugellager, bei welchem die Tragkugeln durch mehrere kleine Trennkugeln in einem für den einwandfreien Lauf derartiger Lager erforderlichen Abstand voneinander gehalten werden. Diese Trennkugeln sind in einem Käfig geführt, ähnlich- wie bei Längs- und Wechs^llagern, der jedoch so ausgebildet ist, daß die Kugeltaschen die Trennkugeln nicht ganz umschließen, sondern diese am äußersten Umhüllungskreis um einen gewissen Betrag freigeben. Derartige Trennkäfige haben den Vorteil, daß die Trennkugeln sich entsprechend der Bewegung der Tragkugeln ab-The invention is a ball bearing, in which the support balls by several small separating balls in one required for the proper running of such bearings Be kept distance from each other. These separating balls are guided in a cage, similar to longitudinal and changeable bearings, which, however, is designed so that the ball pockets do not completely enclose the separating balls, but these at the outermost envelope circle release by a certain amount. Such separating cages have the advantage that the separating balls move accordingly the movement of the supporting balls

wälzen. Außerdem können sich die Käfige mit den Trennkugeln nach allen Richtungen hin einstellen und sich beim Auseinandergehen und Zusammenschieben der T^g^j kugeln nach oben oder unten bewegen, ,sto--. bei die Bewegung nach oben durch das 'Aw liegen der unteren Trennkugeln an den Trag«·.' kugeln und nach unten durch das Aufliegen der unteren ''Trennkugeln auf der Innenringlaufbahn begrenzt wird. Im letzteren Falle rollen die oberen Trennkugeln auf den Tragkugeln ab, während die unteren auf der Innenringlaufbahn abrollen. Die geringe Bauhöhe dieser Trennstücke gestattet das Einbringen der größtmöglichen Anzahl von Tragkugeln, wodurch die Tragfähigkeit dieser Lager ganz wesentlich erhöht wird.roll over. In addition, the cages with the separating balls can move in all directions adjust yourself and yourself when moving apart and pushing together the T ^ g ^ j move balls up or down,, push--. when moving upwards through the 'Aw the lower separating balls lie on the support «·. ' balls and down by resting the lower '' separating balls on the inner ring raceway is limited. In the latter case the upper separating balls roll on the supporting balls, while the lower ones roll on the Roll off the inner ring raceway. The low overall height of these separators allows them to be introduced the largest possible number of support balls, which increases the load-bearing capacity of these Stock is increased quite significantly.

In der Zeichnung ist ein solches Lager mit Trennkugeln beispielsweise dargestellt.In the drawing, such a bearing with separating balls is shown, for example.
