Description
Gebiet der ErfindungTerritory of invention
Die Erfindung betrifft ein Linearwälzlagerelement für die Lagerung an der Lauffläche einer Führungsschiene, mit einem Wälzkörperumläufe aufnehmenden Tragkörper, der für jeweils einen Umlauf eine Tragzone und einen Rücklaufkanal aufweist, die über zwei an dem Tragkörper stirnseitig angrenzende Umlenkkanäle miteinander verbunden sind, welche zumindest teilweise von Umlenkkörpern gebildet sind, die an den beiden Stirnseiten des Tragkörpers lösbar befestigt sind, wobei die Tragzone von einem Steg zur Wälzkörperrückhalterung und der Rücklaufkanal von einer Röhre gebildet, sowie jeweils ein Umlenkkanal von einem inneren Umlenkabschnitt und einem äußeren Umlenkabschnitt begrenzt ist.The The invention relates to a linear roller bearing element for the Storage on the tread a guide rail, receiving with a Wälzkörperumläufe Supporting body, the for one circulation each has a support zone and a return channel, the two on the support body frontally adjacent deflection channels are connected to each other, which are at least partially formed by deflecting bodies, the releasably secured to the two end faces of the support body are, wherein the support zone from a web to the Wälzkörperrückhalterung and the return channel from a tube formed, and in each case a deflection channel of an inner deflection section and an outer deflecting section is limited.
Hintergrund der Erfindungbackground the invention
Bei einem solchen Wälzlagerelement können als Wälzkörper Rollen, Nadeln oder Kugeln verwendet werden. Es bildet einen Führungswagen für Profil schienenführungen, in welchem ein Käfig zum Führen der Wälzkörper angeordnet ist.at such a rolling bearing element can as rolling elements rolling, Needles or balls are used. It forms a carriage for profile rail guides, in which a cage to lead the rolling elements arranged is.

Zusammenfassung der ErfindungSummary the invention
Der Erfindung liegt die Aufgabe zugrunde, das Wälzlagerelement konstruktiv zu vereinfachen und gleichzeitig in seiner Wirkungsweise zu verbessern.Of the Invention is based on the object, the rolling bearing element constructive to simplify and at the same time to improve its mode of action.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass von jedem Umlauf der Steg zur Wälzkörperrückhalterung und die Röhre des Rücklaufkanals, sowie die beiden Umlenkkörper einen zweistückig ausgeführten, längs einer der beiden Ebenen der Tragkörper-Stirnseiten unsymmetrisch geteilten Käfig für Wälzkörper bilden. Alle Stege und Röhren können an jeweils einem ihrer beiden Längsenden mit einem der beiden Umlenkkörper einstückig verbunden sein, wodurch ein als Träger bezeichnetes längeres Teil des Käfigs gebildet ist.These Task is inventively characterized solved, that from each revolution the web to the Wälzkörperrückhalterung and the tube of the Return channel, as well as the two deflection bodies a two-piece executed, along one the two levels of the support body end faces asymmetrically split cage form for rolling elements. All bars and tubes can at one of its two longitudinal ends with one of the two deflection bodies integrally connected be, creating one as a carrier designated longer Part of the cage is formed.
Der Träger kann mit seinen Röhren und Stegen bis zur Anlage seines Umlenkkörpers an dem Tragkörper von einer Stirnseite aus in diesen eingeschoben werden. Es können im eingeschobenen Zustand großflächige Führungszapfen des Trägers aus dem Tragkörper an dessen Stirnseite herausragen, welche von dem Umlenkkörper des Trägers abgewandt ist.Of the carrier can with his tubes and webs to the plant of his diverting body on the support body of a front side are pushed out of these. It can be in inserted state large-area guide pin of the carrier from the supporting body protrude at the end face, which of the deflection of the carrier turned away.
Auf die herausragenden Führungszapfen kann der als kürzeres Teil des Käfigs ausgeführte Umlenkkörper zur Vervollständigung des Käfigs und als Klammer wirkend aufgesteckt werden. Der als Klammer wirkende Umlenkkörper enthält sowohl einen äußeren Umlenkabschnitt als auch einen inneren Umlenkabschnitt, welche den Umlenkkanal für die Wälzkörper bilden. In entsprechend geformte Öffnungen des als Klammer wirkenden Umlenkkörpers können die Führungszapfen eingesteckt werden.On the outstanding guide pin can the shorter one Part of the cage executed deflection body for completion of the cage and be attached as a staple. The parenthesis deflecting contains both an outer deflection section as well as an inner deflection section, which form the deflection channel for the rolling elements. In correspondingly shaped openings of the deflection body acting as a clip, the guide pins can be inserted.

Ein
weiterer Vorteil dieser Käfigvariante
liegt darin, dass der Umlauf unabhängig von der Länge des
Tragkörpers
Sowohl der Träger (durch Materialfluß) als auch die Klammer zentrieren die Elemente des gesamten Käfigs zueinander. Im Vergleich zu konventionellen Käfigen sinkt bei der erfindungsgemäßen Ausführung die Anzahl der Fügestellen. Der Aufwand bezüglich Positionierung bei der Montage sinkt ebenfalls. Die Klammerfunktion kann auch für jeden Umlauf getrennt oder für jeweils zwei oder vier Umläufe zusammen ausgeführt werden. Es ist auch möglich, den Träger dreiteilig auszuführen. Der Rückhaltesteg zwischen den Umläufen ist dabei getrennt montierbar. Die Klammer und der Träger können Aufnahmeelemente zur Fixierung und Positionierung der mittleren getrennten Haltestege enthalten. Sie können auch Front- und Längsdichtungen enthalten, oder Einrichtungen zu deren Aufnahme bzw. Positionierung. Die innere Umlenkung kann im Träger und/oder in der Klammer demontierbar enthalten sein.Either the carrier (by material flow) as well as the clamp center the elements of the entire cage to each other. Compared to conventional cages sinks in the embodiment of the invention Number of joints. The effort regarding Positioning during assembly also decreases. The stapling function can also for each circulation separately or for two or four rounds together accomplished become. It is also possible the carrier in three parts. The retaining bridge between the rounds is separately mountable. The bracket and the carrier may be receiving elements for fixing and positioning the middle separated holding webs contain. You can also Front and longitudinal seals contain or facilities for their inclusion or positioning. The inner deflection can be in the carrier and / or be demountable in the bracket.
