Abstract
Die Erfindung betrifft eine Lagerbaugruppe, insbesondere Wälzlagerbaugruppe, mit wenigstens einem Außenlagerring (1) und vorzugsweise einem Innenlagerring, mit wenigstens einem oder mehreren innerhalb des Außenlagerrings (1) aufgenommenen Gleit- oder Wälzkörper, sowie mit Mitteln zur Fixierung des Außenlagerrings (1) in einer Bohrung (3) eines Aufnahmegehäuses. Zur Lagerfixierung schlägt die Erfindung vor, dass der Außenlagerring (1) entlang dem Außenumfang mit wenigstens einem selbstschneidenden oder selbstfurchenden Gewinde (2) versehen ist, das unter Einwirkung einer Axialkraft auf den Außenlagerring (1) bei gleichzeitiger Rotation des Außenlagerrings (1) mit der Bohrung (3) des Aufnahmegehäuses in Eingriff bringbar ist.The invention relates to a bearing assembly, in particular a rolling bearing assembly, with at least one outer bearing ring (1) and preferably an inner bearing ring, with at least one or more sliding or rolling elements accommodated within the outer bearing ring (1), and with means for fixing the outer bearing ring (1) in one Bore (3) of a housing. To fix the bearing, the invention proposes that the outer bearing ring (1) is provided along the outer circumference with at least one self-tapping or self-tapping thread (2), which under the action of an axial force on the outer bearing ring (1) with simultaneous rotation of the outer bearing ring (1) with the Bore (3) of the receiving housing can be brought into engagement.
Description
Die Erfindung betrifft eine Lagerbaugruppe gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a bearing assembly according to the preamble of
Lagerbaugruppen haben im Hinblick auf den benötigten Bauraum, die Art der Befestigung, der Lagerbelastung und damit auch der Belastungsrichtung, den möglichen übertragbaren Drehzahlen, der Laufgenauigkeit und Laufruhe für die Lagerung von Maschinenteilen große Bedeutung. Hierbei erfordert die Fixierung des Wälzlagers, wie beispielsweise aus der
Daher ist es die Aufgabe der Erfindung, ein Lagerbaugruppe der angegebenen Art dahingehend zu verbessern, dass mit möglichst geringem Aufwand eine einfache, funktionssichere Fixierung des Wälzlagers zustande kommt, die sich im besonderen durch eine großzügig tolerierbare Passung im Aufnahmegehäuse auszeichnet.Therefore, it is the object of the invention to improve a bearing assembly of the specified type to the effect that with the least possible effort a simple, functionally reliable fixation of the bearing comes about, which is characterized in particular by a generously tolerable fit in the receiving housing.
Diese Aufgabe wird erfindungsgemäß für eine Lagerbaugruppe der gattungsbildenden Art durch die kennzeichnenden Merkmale des Patentanspruchs 1 gelöst.This object is achieved for a bearing assembly of the generic type by the characterizing features of
Weitere Merkmale, Vorteile sowie Einzelheiten der Erfindung gehen im nachfolgenden aus der Beschreibung einer Ausführungsform anhand mehrerer Zeichnungen hervor.Further features, advantages and details of the invention will become apparent hereinafter from the description of an embodiment with reference to several drawings.
