Pivot bearings, in particular for vehicle seats, with two bearing washers (14) which can be rotated relative to one another about an axis of rotation and are supported on one another by an axial deep groove ball bearing (16) which has two bearing rings (20, 22), each of which has two annular grooves ( 26, 32) for receiving bearing balls (34), characterized in that the bearing rings (20, 22) form two C-profiles, the parallel legs (24, 30) of which are oriented at right angles to the axis of rotation and which interlock in such a way that one C-profile engages around the other, and that the grooves (26, 32) are formed in the legs (24, 30) of these C-profiles, which are parallel to each other in pairs.
Description
Die Erfindung betrifft ein Drehlager, insbesondere für Fahrzeugsitze, mit zwei Lagerscheiben, die um eine Drehachse relativ zueinander drehbar sind und aneinander durch ein Axial-Rillenkugellager abgestützt sind, das zwei Lagerringe aufweist, die jeweils zwei ringförmige Rillen zur Aufnahme von Lagerkugeln bilden.The invention relates to a pivot bearing, in particular for vehicle seats, with two bearing disks which are rotatable about an axis of rotation relative to one another and are supported on one another by an axial deep groove ball bearing that has two bearing rings that each form two annular grooves for receiving bearing balls.
Solche Drehlager dienen insbesondere zur drehbaren Lagerung von Sitzen in autonomen Kraftfahrzeugen und ermöglichen es dann den Fahrzeuginsassen, die Orientierung ihres Sitzes zu verändern.Such pivot bearings are used in particular for the rotatable mounting of seats in autonomous motor vehicles and then enable the vehicle occupants to change the orientation of their seat.
Aus
Aufgabe der Erfindung ist es, ein Drehlager zu schaffen, das einen einfachen und kompakten Aufbau aufweist und bei dem die Lagerringe stabil zusammengehalten sind. The object of the invention is to create a pivot bearing which has a simple and compact structure and in which the bearing rings are held together in a stable manner.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Lagerringe zwei C-Profile bilden, deren parallele Schenkel rechtwinklig zur Drehachse orientiert sind und die so ineinandergreifen, dass das eine C-Profil das andere umgreift, und dass die Rillen in den paarweise parallel zueinander verlaufenden Schenkeln dieser C-Profile gebildet sind.This object is achieved according to the invention in that the bearing rings form two C-profiles, the parallel legs of which are oriented at right angles to the axis of rotation and which interlock so that one C-profile engages around the other, and that the grooves in the legs running parallel to one another in pairs these C-profiles are formed.
Die Profilkonfiguration der Lagerringe entspricht damit der Profilkonfiguration, die bei Auszugschienen für Möbelschubladen üblich ist, nur dass die Schienen dort geradlinig verlaufen, während sie bei dem erfindungsgemäßen Drehlager zu Kreisringen geschlossen sind. Die Laufbahnen für die Lagerkugeln werden jeweils durch zwei einander gegenüberliegende und zueinander offene Rillen der beiden Lagerringe gebildet. Durch den Eingriff der Lagerkugeln in diese Rillen werden dann die beiden Lagerringe sowohl in axialer Richtung als auch in radialer Richtung stabil in Position gehalten. Die Laufbahnen für die Lagerkugeln verlaufen axial in Abstand zueinander und können den gleichen Durchmesser haben. Dadurch wird für das Drehlager insbesondere in radialer Richtung nur ein geringer Bauraum benötigt.The profile configuration of the bearing rings thus corresponds to the profile configuration that is common with pull-out rails for furniture drawers, only that the rails run in a straight line there, while they are closed to form circular rings in the pivot bearing according to the invention. The raceways for the bearing balls are each formed by two mutually opposite and mutually open grooves of the two bearing rings. As a result of the engagement of the bearing balls in these grooves, the two bearing rings are then held in a stable position both in the axial direction and in the radial direction. The raceways for the bearing balls run axially at a distance from one another and can have the same diameter. As a result, only a small amount of space is required for the rotary bearing, particularly in the radial direction.
Bei der Herstellung des Drehlagers kann man beispielsweise so vorgehen, dass zunächst zwei geradlinig verlaufende Profilschienen hergestellt werden, die mit den Lagerkugeln bestückt und axial ineinander geschoben werden und dann gemeinsam zu Kreisringen gebogen werden. Alternativ können die Profilschienen zunächst die Form von Kreissegmenten haben, die paarweise miteinander in Eingriff gebracht werden, wonach die Paare zu einem geschlossenen Ring verbunden werden. In noch einer anderen Ausführungsform haben die Profilschienen zunächst die Form von Spiralen, die jeweils eine vollständige Windung bilden und die dann ineinander „geschraubt“ und schließlich zu einem Ring geschlossen werden.When producing the pivot bearing, one can proceed, for example, in such a way that first two linear profile rails are produced, which are fitted with the bearing balls and axially pushed into one another and then bent together to form circular rings. Alternatively, the profile rails can initially have the shape of circular segments that are brought into engagement with one another in pairs, after which the pairs are connected to form a closed ring. In yet another embodiment, the profile rails initially have the shape of spirals, which each form a complete turn and which are then “screwed” into one another and finally closed to form a ring.
