Gebiet der ErfindungField of the invention
Die Erfindung betrifft eine Lager-Freilauf-Einheit, welche als Baueinheit eine Freilaufkupplung sowie ein Wälzlager umfasst.The The invention relates to a bearing-freewheel unit, which as a structural unit an overrunning clutch and a rolling bearing comprises.
Hintergrund der ErfindungBackground of the invention

Lager-Freilauf-Einheit ist beispielsweise aus der
Aufgabe der ErfindungObject of the invention
Der Erfindung liegt die Aufgabe zugrunde, eine besonders vielseitig verwendbare Lager-Freilauf-Einheit, welche für unterschiedlichste Belastungszustände geeignet ist, anzugeben.Of the Invention is based on the object, a particularly versatile usable bearing-freewheel unit, which for a variety of Load conditions is appropriate to specify.
Zusammenfassung der ErfindungSummary of the invention
Diese Aufgabe wird erfindungsgemäß gelöst durch eine Lager-Freilauf-Einheit mit den Merkmalen des Anspruchs 1. Diese Vorrichtung umfasst als kompakte Baueinheit Radial- und Axiallagerfunktionen sowie eine Freilauffunktion. Zwischen den Lagerringen, d. h. zwischen dem Innenring und dem konzentrisch zu diesem angeordneten Außenring, befinden sich eine als zweireihiges Schrägwälzlager ausgebildete Wälzlagereinheit sowie eine Freilaufeinheit, welche eine Drehmomentübertragung zwischen dem Innenring und dem Außenring nur bei einer bestimmten Drehrichtung des Innenrings relativ zum Außenring ermöglicht. Die vorzugsweise als formschlüssige Freilaufkupplung, insbesondere als Klemmkörperfreilauf, ausgebildete Freilaufeinheit befindet sich axial zwischen den beiden Wälzkörperreihen der Wälzlagereinheit. Unter einem Klemmkörperfreilauf wird eine Freilaufkupplung verstanden, deren Klemmkörper einen nicht kreisförmigen Querschnitt haben und mit zylindrischen Klemmbahnen zusammenwirken. Die Klemmbahnen, d. h. die Innenklemmbahn sowie die Außenklemmbahn, sind im vorliegenden Fall vorzugsweise direkt durch den Innenring bzw. durch den Außenring gebildet.These The object is achieved by a bearing-freewheel unit with the features of claim 1. This Device comprises as a compact unit radial and thrust bearing functions and a freewheeling function. Between the bearing rings, d. H. between the inner ring and the outer ring arranged concentrically therewith, are a double-row skew bearings trained rolling bearing unit and a freewheel unit, which a torque transmission between the inner ring and the outer ring only in a certain direction of rotation allows the inner ring relative to the outer ring. The preferably as a positive overrunning clutch, in particular As sprag freewheel, trained freewheel unit is located axially between the two rows of rolling elements the rolling bearing unit. Under a sprag freewheel is understood as an overrunning clutch whose clamping body have a non-circular cross-section and cylindrical Collets cooperate. The clamps, d. H. the inner clamping track and the outer clamping track are preferred in the present case formed directly through the inner ring or through the outer ring.
In besonders vorteilhafter Ausgestaltung weist der Außenring im Bereich der Außenklemmbahn seine maximale Wandstärke auf. Der Außenring ist damit in der Lage, besonders hohe beim Blockieren der Freilaufeinheit auftretende Radialkräfte aufzunehmen. Die in Axialrichtung beidseitig der Außenklemmbahn benachbarten Außenlaufbahnen, auf welchen jeweils eine Reihe an Wälzkörpern der Wälzlagereinheit abrollt, befinden sich radial außerhalb der Außen klemmbahn. In analoger Weise erstrecken sich die Innenlaufbahnen der Wälzkörper von der Innenklemmbahn aus radial nach außen oder sind, von der Innenklemmbahn abgesetzt, vollständig radial außerhalb der Innenklemmbahn angeordnet. Der Innenring der Lager-Freilauf-Einheit weist damit, im Gegensatz zum Außenring, eine zu den Stirnseiten hin zunehmende Wandstärke auf. Die Wälzkörper befinden sich dementsprechend in O-Anordnung zwischen den Lagerringen. Dies gilt sowohl für Kugeln als Wälzkörper als auch für rollenförmige Wälzkörper. Auch Kugelrollen sind als Wälzkörper des zweireihigen Schrägwälzlagers geeignet. Sie zeichnen sich durch einen besonders geringen Bauraumbedarf aus. In besonders bevorzugter Ausgestaltung werden als Wälzkörper Zylinderrollen verwendet. Die Lager-Freilauf-Einheit ist damit zur Aufnahme besonders hoher Belastungen, auch Kippmomente, geeignet. Die Laufbahnen der Wälzlager sind gegenüber der Axialrichtung der Lager-Freilauf-Einheit vorzugsweise um 30° bis 60°, insbesondere um 45°, schräg gestellt.In particularly advantageous embodiment, the outer ring in the area of the outer clamping track its maximum wall thickness on. The outer ring is thus able, particularly high to absorb radial forces occurring during the blocking of the freewheel unit. The adjacent in the axial direction on both sides of the outer clamping track Outer raceways, on each of which a number of rolling elements the rolling bearing unit rolls, are located radially outside the outer cable car. In an analogous manner extend the Inner raceways of the rolling elements of the inner clamping track from radially outward or are, from the inner clamping track offset, completely radially outside of the inner clamping track arranged. The inner ring of the bearing-freewheel unit thus indicates, in the Contrary to the outer ring, one towards the front sides increasing Wall thickness on. The rolling elements are located Accordingly, in O-arrangement between the bearing rings. This applies to both balls as rolling elements as well as roller-shaped rolling elements. Also ball rollers are as rolling elements of the double row Schrägwälzlagers suitable. They stand out a particularly small space requirement. In particularly preferred Design are as rolling elements cylindrical rollers used. The bearing-freewheel unit is thus particularly suitable for receiving high loads, including tilting moments, suitable. The raceways of Rolling bearings are compared to the axial direction of the Bearing freewheel unit preferably by 30 ° to 60 °, in particular at 45 °, inclined.
Die Lager-Freilauf-Einheit kann an beiden Stirnseiten jeweils mit einem schleifenden oder nicht schleifenden Dichtring abgedichtet sein. Zur Erstbefettung des Lagers eignet sich besonders eine Schmierungsbohrung, welche sich vom Außenumfang des Außenrings in Radialrichtung bis zur Außenklemmbahn erstreckt.The Bearing freewheel unit can be connected to both ends with one be sealed sliding or non-abrasive sealing ring. For Erstbefettung the camp is especially a lubrication hole, which extends from the outer circumference of the outer ring in Radial direction extends to the outer clamping track.
Während der Außenring der Lager-Freilauf-Einheit vorzugsweise einteilig ausgebildet ist, ist der Innenring – bei O-Anordnung der Wälzkörper – als gesprengter Lagerring ausgeführt. Vorzugsweise ist der Innenring asymmetrisch gesprengt, so dass sämtliche Wälzkörper und Klemmkörper von der umlaufenden Sprengfuge beabstandet sind.While the outer ring of the bearing-freewheel unit preferably in one piece is formed, the inner ring - in O-arrangement of Rolling elements - as a blown bearing ring executed. Preferably, the inner ring is asymmetrical blasted, leaving all rolling elements and clamp body spaced from the peripheral explosive joint are.
