Abstract
Eine Lageranordnung umfasst ein Außenteil und Innenteil, die über Wälzkörper nach Art eines Wälzlagers wenigstens verschwenkbar gegeneinander gelagert sind, und ein Dichtungsteil, das zwischen einem die Wälzkörper beinhaltenden Raum und der Umgebung abdichtetet, wobei das Wälzlager und das Dichtungsteil derart gestaltet sind, dass sie dynamische Auslenkungen von der Achsenparallelität von Außenteil zu Innenteil von bis zu ca. ± 2° funktionserhaltend ermöglichen.A bearing arrangement comprises an outer part and an inner part which are at least pivotably supported relative to one another via rolling elements in the manner of a rolling bearing, and a sealing part which seals between a space containing the rolling elements and the surroundings, the rolling bearing and the sealing part being designed in such a way that they are dynamic Allow deflections of the parallelism of the axes from the outer part to the inner part of up to approx. ± 2 ° to maintain the function.
Description
Die Erfindung betrifft eine Lageranordnung und eine Verwendung der Lageranordnung.The invention relates to a bearing arrangement and a use of the bearing arrangement.
Aus dem Stand der Technik sind Lageranordnungen bekannt, umfassend ein eigentliches Wälzlager und ein das Wälzlager umgebendes Gehäuseteil, in dem das Wälzlager angeordnet ist, zur Lagerung einer Walze oder einer durch eine Hintereinanderreihung mehrerer Scheiben gebildeten Walze eines landwirtschaftlichen Bodenbearbeitungsgeräts, insbesondere bei einer Stabwalze, Zahnpackerwalze, Keilringwalze, Cracker-Disk-Walze, Trapezringwalze oder dergleichen. Dabei kommt es aber immer wieder zu Ausfällen, bei denen unter anderem das Gehäuseteil durch Überhitzung beschädigt wird.Bearing arrangements are known from the prior art, comprising an actual roller bearing and a housing part surrounding the roller bearing, in which the roller bearing is arranged, for mounting a roller or a roller of an agricultural tillage implement, in particular in the case of a rod roller, tooth packer roller, formed by a series of disks , Wedge ring roller, cracker disk roller, trapezoidal ring roller or the like. However, there are always failures in which, among other things, the housing part is damaged by overheating.
Eine Aufgabe der Erfindung ist es daher, eine Lageranordnung zu schaffen, bei der dieses Problem beherrscht ist.An object of the invention is therefore to provide a bearing arrangement in which this problem is mastered.
Diese Aufgabe wird durch den Gegenstand des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen sind in den Unteransprüchen beschrieben.This object is solved by the subject matter of claim 1. Advantageous refinements are described in the subclaims.
Die Erfindung beruht dabei unter anderem auf dem Erkennen, dass besagte Ausfälle durch dynamische Achsenparallelitätsabweichungen zwischen der Hauptachse der Walze und deren Lageraufnahme beim Nutzen der Walze herrühren.The invention is based, inter alia, on the recognition that said failures result from dynamic axis parallelism deviations between the main axis of the roller and its bearing support when using the roller.
Vorteile, Merkmale und Einzelheiten der Erfindung ergeben sich aus den im Folgenden beschriebenen Ausführungsbeispielen der Erfindung anhand der Figuren.Advantages, features and details of the invention result from the exemplary embodiments of the invention described below with reference to the figures.
