Abstract
Description
Gebiet der ErfindungField of the invention
Die Erfindung betrifft ein Rollenlager, bestehend aus einem ersten Lagerring, einem zweiten Lagerring sowie dazwischen auf Laufbahnen der Lagerringe abrollenden und in Taschen eines Käfigs geführten ein- oder mehrreihig angeordneten Rollen, wobei der Käfig zwei in Umfangsrichtung verlaufende Umfangsstege sowie diese Umfangsstege verbindende Verbindungsstege aufweist, und bei dem die Umfangsstege sowie die Verbindungsstege die Taschen zur Aufnahme der Rollen bilden.The invention relates to a roller bearing, consisting of a first bearing ring, a second bearing ring and between rolling on raceways of the bearing rings and guided in pockets of a cage single or multi-row rollers, wherein the cage has two circumferentially extending circumferential webs and connecting said circumferential webs connecting webs, and in which the peripheral webs and the connecting webs form the pockets for receiving the rollers.

Aus der
Aufgabe der ErfindungObject of the invention
Vor diesem Hintergrund liegt der Erfindung die Aufgabe zugrunde, eine Führung zwischen einem Käfig und den Wälzkörpern eines Rollenlagers zu schaffen, durch die sich vorzeitige Verletzungen der Funktionsflächen der Wälzkörper vermeiden lassen.Against this background, the invention has for its object to provide a guide between a cage and the rolling elements of a roller bearing, can be avoided by the premature injuries of the functional surfaces of the rolling elements.
Zusammenfassung der ErfindungSummary of the invention
Zur Lösung dieser Aufgabe ist bei einem Rollenlager der eingangs erwähnten Art vorgesehen, dass die Rollen in ihren Stirnseiten jeweils eine zentrische axiale Vertiefung aufweisen, dass an der Innenseite der Umfangsstege Vorsprünge ausgebildet sind, welche in die Vertiefungen der Rollen eingreifen und die Rollen in Achsrichtung sowie in Rollrichtung führen, und dass an den Verbindungsstegen Ersatzführungsflächen ausgebildet sind, welche erst bei einem weitgehenden Verschleiß der Vorsprünge die Aufgabe der Führung der Rollen übernehmen, und bis dahin einen Abstand zu der Mantelfläche der Rollen haben.To achieve this object, it is provided in a roller bearing of the type mentioned that the rollers each have a central axial recess in their end faces, that on the inside of the circumferential webs projections are formed, which engage in the recesses of the rollers and the rollers in the axial direction as well lead in the rolling direction, and that at the connecting webs replacement guide surfaces are formed, which assume the task of guiding the rollers only at a substantial wear of the projections, and until then have a distance from the lateral surface of the rollers.
Durch diese Konstruktion wird erreicht, dass die Rollen in ihrer Achsrichtung und in Rollrichtung präzise geführt werden und mit den Ersatzführungsflächen der Verbindungsstege, wenn überhaupt, erst nach sehr langer Laufzeit in Berührung kommen, so dass sich auch keine feinen Partikel an den Ersatzführungsflächen anlagern und als Schmiergelfläche auf die Wälzkörperstirnflächen wirken können. Da sich die Ersatzführungsflächen der Verbindungsstege und die Rollen zumindest während eines sehr großen Anteils der Lagerlebensdauer nicht berühren, ist eine zuverlässige, ungestörte Schmiermittelversorgung an den kritischen Bereichen der Rollenmantelflächen gewährleistet.This construction ensures that the rollers are precisely guided in their axial direction and in the rolling direction and come into contact with the replacement guide surfaces of the connecting webs, if at all, only after a very long period of time, so that no fine particles attach themselves to the replacement guide surfaces and Lubricating surface can act on the Wälzkörperstirnflächen. Since the replacement guide surfaces of the connecting webs and the rollers do not touch, at least during a very large portion of the bearing life, a reliable, undisturbed lubricant supply is ensured at the critical areas of the roller shell surfaces.
Zum Erleichtern des Einklipsens der Rollen in die Taschen des Käfigs können die Vorsprünge der Umfangsstege konisch ausgebildet und/oder mit einseitigen oder beidseitigen schrägen Anflächungen versehen sein.To facilitate the Einklipsens the roles in the pockets of the cage, the projections of the peripheral webs may be conical and / or be provided with unilateral or bilateral oblique flats.
Eine weitere Erleichterung des Einklipsens der Rollen in die Taschen besteht darin, dass der Käfig im Bereich der Anbindung der Verbindungsstege an die Umfangsstege elastisch nachgiebig ausgebildet ist, vorzugsweise indem die Umfangsstege im Bereich der Anbindung an die Verbindungsstege nach außen ausgerundet ausgebildet sind. A further facilitating the Einklipsens the roles in the pockets is that the cage is formed in the region of the connection of the connecting webs to the peripheral webs elastically yielding, preferably by the circumferential webs in Area of connection to the connecting webs are rounded outwards.
Um Materialanhäufungen im Bereich der Vorsprünge zu vermeiden und Gewicht einzusparen, können die Umfangsstege an ihren den Vorsprüngen abgewandten Außenseiten im Bereich der Vorsprünge diesbezüglich kongruente Vertiefungen aufweisen.In order to avoid accumulation of material in the region of the projections and to save weight, the peripheral webs may have congruent recesses in their projections in the region of the projections facing away from the projections.
Im Fall der Verwendung des Rollenlagers für Großwälzlager mit einem Teilkreisdurchmesser > 0,5 m, insbesondere als Rotor-Hauptlager in einer Windkraftanlage, kann der Käfig als Kunststoffspritzgussteil, insbesondere aus PEEK (Poly-Ether-Ether-Keton), gefüllt mit Glasfasern oder Kohlefasern, hergestellt und als Segmentkäfig ausgebildet sein.In the case of using the roller bearing for slewing bearings with a pitch circle diameter> 0.5 m, especially as a rotor main bearing in a wind turbine, the cage as a plastic injection molded part, in particular PEEK (polyether ether ketone), filled with glass fibers or carbon fibers , manufactured and designed as a segment cage.
