Abstract
Description
Bei der Befestigung eines Lagers an einem Maschinenteil tritt mitunter das Problem auf, dass das Maschinenteil und das Lager radial zueinander beabstandet sind und somit eine direkte Fixierung des Lagers am Maschinenteil nicht möglich ist. Diesbezüglich ist es bereits bekannt, zwischen dem Lager und dem Maschinenteil einen Zwischenring einzufügen, dessen Wandstärke auf den radialen Abstand zwischen dem Lager und dem Maschinenteil abgestimmt ist.When attaching a bearing The problem sometimes arises on a machine part that the Machine part and the bearing are radially spaced from each other and therefore a direct fixation of the bearing on the machine part is not possible. In this regard, it is already known between the bearing and the machine part insert an intermediate ring, its wall thickness on the radial distance between the bearing and the machine part is coordinated.
Weiterhin ist aus der GB-PS 1 028 191 ein Montageteil für einen Lageraußenring bekannt, mit dem die Außenumfangsfläche eines Lagers auf einen radialen Abstand zu einer Wandfläche einer Bohrung, in der das Lager montiert werden soll, gebracht werden kann. Das Montageteil weist eine Scheibe mit einer Vielzahl von nachgiebigen Fingern auf, die sich am Lageraußenring abstützen. Die Scheibe stützt sich ihrerseits in der Bohrung ab. In einer Variante stützen sich die Finger in der Bohrung und die Scheibe am Lageraußenring ab.Furthermore, from GB-PS 1 028 191 a mounting part for a bearing outer ring known with which the outer peripheral surface of a Bearing to a radial distance from a wall surface Hole in which the bearing is to be mounted can. The mounting part has a disc with a variety of yielding fingers, which are supported on the bearing outer ring. The Disc is supported in turn in the hole. In one variant, they are supported the fingers in the hole and the washer on the bearing outer ring from.
Die
Mit den bekannten Hilfsmitteln lässt sich zwar eine Fixierung eines Lagers in einem radialen Abstand zu einer Bohrungsfläche erreichen, allerdings ist die damit erzielbare Positioniergenauigkeit des Lagers relativ zur Bohrungsfläche außen im Fall des Zwischenrings nicht besonders hoch. Der Zwischenring hat den Nachteil, dass er relativ schwer ist und sehr genau gefertigt sein muss.With the known aids, achieve fixation of a bearing at a radial distance from a bore surface, however, the positioning accuracy of the bearing that can be achieved with it relative to the bore area Outside not particularly high in the case of the intermediate ring. The intermediate ring has the disadvantage that it is relatively heavy and manufactured very precisely have to be.
Der Erfindung liegt die Aufgabe zugrunde, eine Fixierung eines Lagers in einem radialen Abstand zu einem Maschinenteil mit hoher Präzision und einem vertretbaren Aufwand zu ermöglichen.The invention has for its object a Fixing a bearing at a radial distance from a machine part with high precision and to allow a reasonable effort.
Diese Aufgabe wird durch die Merkmalskombination des Anspruchs 1 gelöst.This task is accomplished through the combination of features of claim 1 solved.
Der erfindungsgemäße Lagerträger zur Fixierung eines Lagers in einem radialen Abstand zu einem Maschinenteil weist eine erste radiale Sitzfläche für das Lager und eine zweite radiale Sitzfläche für das Maschinenteil auf. Die Besonderheit des erfindungsgemäßen Lagerträgers besteht darin, dass wenigstens eine der beiden Sitzflächen als Mantelfläche eines zylindrischen Rohrabschnitts ausgebildet ist, dessen Wandstärke kleiner ist als die radiale Entfernung zwischen der ersten Sitzfläche und der zweiten Sitzfläche.The bearing bracket according to the invention for fixing a bearing a first points at a radial distance from a machine part radial seat for the Bearing and a second radial seat for the machine part. The Special feature of the bearing bracket according to the invention in that at least one of the two seat surfaces is the outer surface of one cylindrical tube section is formed, the wall thickness is smaller is the radial distance between the first seat and the second seat.
Die Erfindung hat den Vorteil, dass damit eine präzise Positionierung des Lagers relativ zum Maschinenteil möglich ist. Ein weiterer Vorteil besteht darin, dass der erfindungsgemäße Lagerträger vergleichsweise kostengünstig herstellbar ist.The invention has the advantage that thus a precise Positioning of the bearing relative to the machine part is possible. Another advantage is that the bearing bracket according to the invention is comparative economical can be produced.
Außerdem kann der erfindungsgemäße Lagerträger mit einem vergleichsweise geringen Gewicht hergestellt werden.In addition, the bearing bracket according to the invention a comparatively low weight.
Vorzugsweise überlappen die erste Sitzfläche und die zweite Sitzfläche in Axialrichtung. Dies hat den Vorteil, dass die Fixierung des Lagerträgers relativ stabil ist. Insbesondere kann der erfindungsgemäße Lagerträger einen U-förmigen Querschnitt aufweisen. Damit lässt sich ein guter Ausgleich zwischen den Forderungen nach einer möglichst hohen Stabilität und einem möglichst geringen Gewicht herstellen. Außerdem ist eine derartige Form herstellungstechnisch unproblematisch.Preferably, the first seat and overlap the second seat in the axial direction. This has the advantage that the fixation of the bearing bracket is relative is stable. In particular, the bearing bracket according to the invention can have a U-shaped cross section. With that leaves a good balance between the demands for a possible high stability and one if possible produce light weight. Moreover Such a form is unproblematic in terms of production technology.
Der erfindungsgemäße Lagerträger kann wenigstens einen Axialanschlag zur Fixierung des Lagers oder des Maschinenteils in Axialrichtung aufweisen. Dieser Axialanschlag kann beispielsweise als ein sich in Radialrichtung erstreckender Flansch ausgebildet sein. Weiterhin ist es möglich, den Axialanschlag als eine Verstemmung auszubilden. Insbesondere kann der Axialanschlag wenigstens ein Segment aufweisen, dass sich über einen Teilbereich des Umfangs erstreckt. Mit dem Axialanschlag wird eine sichere axiale Fixierung des Lagers relativ zum Maschinenteil erreicht, wobei angesichts der vielfältigen Möglichkeiten zur Ausbildung des Axialanschlags die Besonderheiten des jeweiligen Anwendungsfalls berücksichtigt werden können.The bearing bracket according to the invention can have at least one axial stop for fixing the bearing or the machine part in the axial direction exhibit. This axial stop can, for example, be as one be formed in the radial direction extending flange. Farther Is it possible, to design the axial stop as a caulking. In particular the axial stop can have at least one segment that extends over a Part of the circumference extends. With the axial stop a safe axial fixation of the bearing relative to the machine part achieved, being given the diverse possibilities the special features of the respective to form the axial stop Considered if necessary can be.
In einem bevorzugten Ausführungsbeispiel weist der Lagerträger im axialen Bereich zwischen der ersten Sitzfläche und der zweiten Sitzfläche eine axial durchgehende Öffnung auf. Die Umfangserstreckung der Öffnung ist vorzugsweise größer als die Erstreckung in Radialrichtung. Eine derartige Öffnung kann beispielsweise zur Durchführung von Werkzeugen genutzt werden, so dass der Bereich hinter dem Lager auch ohne Demontage des Lagers zugänglich ist.In a preferred embodiment the bearing bracket one axial in the axial area between the first seat and the second seat continuous opening on. The circumferential extent of the opening is preferably greater than the extension in the radial direction. Such an opening can for example to carry out used by tools so that the area behind the warehouse is accessible even without dismantling the bearing.
Der erfindungsgemäße Lagerträger kann einteilig ausgebildet sein und als Blechteil, Gussteil, Sinterteil oder Kunststoffteil realisiert sein. In beiden Fällen können die Fertigungskosten in einem vertretbaren Rahmen gehalten werden.The bearing bracket according to the invention can be formed in one piece and as a sheet metal part, cast part, sintered part or plastic part be realized. In both cases can the manufacturing costs are kept within reasonable limits.
Insbesondere eignet sich der erfindungsgemäße Lagertträger für den Einbau in ein Getriebe.The bearing bracket according to the invention is particularly suitable for installation in a gearbox.
