Description
Die Erfindung betrifft ein Kugellager für Längsbewegungen mit wenigstens zwei am Umfang verteilt angeordneten endlosen Reihen von Kugeln sowie eine Kugelkette.The The invention relates to a ball bearing for longitudinal movements with at least two arranged on the circumference arranged endless rows of balls as well a ball chain.

Eine Aufgabe der Erfindung ist es, ein verbessertes Kugellager für Längsbewegungen mit wenigstens zwei am Umfang verteilt angeordneten endlosen Reihen von Kugeln zu schaffen, so dass unter anderem bei wenigstens gleichbleibender Funktionssicherheit verbesserte Eigenschaften des Kugellagers erzielt werden.A The object of the invention is to provide an improved ball bearing for longitudinal movements with at least two arranged on the circumference arranged endless rows of bullets, so that among other things at least consistent Functional safety improved properties of the ball bearing achieved become.
Die Aufgabe wird durch Gegenstand des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen sind in den Unteransprüchen beschrieben.The The object is solved by the subject matter of claim 1. advantageous Embodiments are described in the subclaims.
Gemäß Anspruch 1 beinhaltet ein Kugellager folgende Merkmale:
- – Ein Außenteil des Kugellagers umfasst eine Höhlung und Führungen für wenigstens zwei am Umfang verteilt angeordnete endlose Reihen von Kugeln,
- – das Außenteil ist derart ausgebildet, dass in der Höhlung ein Innenteil einsetzbar ist, dessen Außenmantel wenigstens in einem zum Längsverschieben vorgesehenen Längsabschnitt entsprechend einem Kreiszylindermantel ausgebildet ist, so dass über die Kugeln Innen- und Außenteil gegeneinander längsverschieblich sind, und
- – zwischen den Kugeln wenigstens einer der Reihen sind ein unmittelbares Berühren der Kugeln untereinander verhindernde Zwischenelemente angeordnet.
- - An outer part of the ball bearing comprises a cavity and guides for at least two circumferentially arranged endless rows of balls,
- - The outer part is formed such that in the cavity, an inner part is used, the outer shell is formed at least in a longitudinal section provided for longitudinal displacement corresponding to a circular cylinder shell, so that over the balls inner and outer parts against each other are longitudinally displaceable, and
- - Between the balls of at least one of the rows a direct contact of the balls with each other preventing intermediate elements are arranged.
Dadurch, dass bei besagtem Kugellager für Längsbewegungen die Kugeln durch Zwischenelemente voneinander getrennt sind, die mit besonderem Vorteil zu einer Kette verbunden sein können, wird insbesondere gegenüber einem vergleichbaren Kugellager, bei dem die Kugeln ohne Trennung voneinander geführt sind, bei Betrieb des Kugellagers aufgrund des unterbundenen Aneinanderstoßens von Kugeln mit Vorteil eine deutliche Geräuschreduzierung erzielt und auch die Reibung mit Vorteil reduziert, da ein Berühren zweier benachbarter Kugeln mit an der Berührstelle gegensinniger Bewegungsrichtung durch die Zwischenelemente unterbunden ist. Die Lebensdauer eines erfindungsgemäßen Lagers ist weiterhin auch noch dadurch erhöht, dass zwischen den Kugeln aufgrund der Zwischenelemente sozusagen Schmiermit telreservoirs ausgebildet sind. Schließlich ist beim erfindungsgemäßen Lager auch eine Montage des Lagers vereinfacht.Thereby, that at said ball bearing for longitudinal movements the balls are separated by intermediate elements, the be associated with particular advantage to a chain is especially opposite a comparable ball bearing, where the balls without separation guided by each other are, when operating the ball bearing due to the suppressed abutment of Bullets with advantage achieved a significant noise reduction and also reduces friction with advantage, since touching two adjacent balls with opposite direction of contact at the contact point is prevented by the intermediate elements. The life of a inventive bearing is also still increased by the fact that between the balls due to the intermediate elements so to speak Schmiermit telreservoirs are formed. After all is at the camp of the invention also simplifies assembly of the bearing.
Die Erfindung beruht dabei auf der Erkenntnis, dass auch bei einem, entlang einer kreiszylinderartigen Achse bzw. Welle hin- und herbewegbaren und dadurch geführten Linearkugellager mit Kugelumlauf besagte Zwischenelemente, insbesondere in der Ausbildung als eine die Kugeln auf Abstand zueinander haltende Kette, ohne technische Probleme einsetzbar und damit unter anderem vorgenannte Vorteile erzielbar sind. Dahingegen ist aus dem Stand der Technik der Einsatz von Kugelketten lediglich bei Anordnungen, bei denen aufgrund einer aufeinander abgestimmten Formgebung der beiden zueinander längsbewegbaren Teile ein Rotieren der Teile zueinander ausgeschlossen ist, beispielsweise bei profilschienenartigen Linearführungen und Keilwellen, und bei Anordnungen mit ausschließlich schraubenlinienartigen Vorschiebebewegungen, beispielsweise bei Kugelgewindetrieben, bekannt. Bislang ist also der Einsatz von Zwischenelementen bzw. Ketten lediglich bei Anordnungen technisch erprobt, bei denen von Hause aus durch die Gestaltung der beiden zueinander längsbewegbaren Teile ein Drehen der Teile gegeneinander mit den dabei auftretenden Kräfte ausgeschlossen ist (Linearführung und Keilwelle) bzw. ausschließlich schraubenlinienartig erfolgen kann (Kugelgewindetrieb).The Invention is based on the recognition that even at a along a circular cylindrical axis or wave back and forth and guided by it Linear ball bearing with ball circulation said intermediate elements, in particular in training as one holding the balls at a distance from each other Chain, can be used without technical problems and thus among others The aforementioned advantages can be achieved. In contrast, is out of the state the technique of using ball chains only in arrangements, where due to a coordinated shaping of the both longitudinally movable Parts of a rotation of the parts to each other is excluded, for example at Profile rail-like linear guides and splines, and in arrangements exclusively helical Vorschiebebewegungen, for example in ball screws, known. So far, so the use of intermediate elements or chains only Technically tested in arrangements in which by home by the design of the two longitudinally movable parts rotate the parts against each other with the forces occurring excluded is (linear guide and spline) or exclusively can be helical (ball screw).
In einer vorteilhaften Ausgestaltung sind die Kugeln in einer Kugelkette angeordnet. Dabei ist gegenüber Lösungen mit zwischen den Kugeln angeordneten einzelnen Zwischenelementen durch die Kugelkette eine gewisse, bei den Einzelelementen bestehende Restgefahr eines Überrollens der Einzelelemente durch die Kugeln entgegengewirkt.In According to an advantageous embodiment, the balls are in a ball chain arranged. It is opposite solutions with arranged between the balls individual intermediate elements through the ball chain a certain, existing in the individual elements Residual danger of a rollover the individual elements counteracted by the balls.
