Description
Lagernabe für WälzlagerBearing hub for roller bearings
Stand der Technik Die Erfindung geht aus von einer Lagernabe nach der Gattung des Hauptanspruchs. Bei elektrischen Maschinen mit hoher Schüttelbeanspruchung, beispielsweise bei Generatoren, die in Kraftfahrzeuge eingebaut sind, kann das als Wälzlager ausgebildete Kugellager oder Rollenlager ausschlagen. Dies ist besonders dann der Fall, wenn das aus Stahlteilen bestehende Wälzlager in Lagernaben aus Leichtmetall eingesetzt ist, und zwar deshalb, weil Stahl und Leichtmetall unterschiedliche Wärmeausdehnungskoeffizieten haben und weil das Leichtmetall im Vergleich zu dem Stahl verhältnismäßig weich ist. Besonders häufig tritt der Fehler dann auf, wenn das Wälzlager als Loslager ausgebildet ist, also als ein Lager, das in axialer Richtung verschiebbar ist.PRIOR ART The invention is based on a bearing hub the genre of the main claim. In the case of electrical machines with high vibration loads, For example, in the case of generators that are built into motor vehicles, this can be as Knock out ball bearings or roller bearings formed by roller bearings. This is special then the case when the rolling bearing made of steel parts is in bearing hubs made of light metal is used because steel and light metal have different coefficients of thermal expansion have and because that Light metal in comparison to the steel in proportion is soft. The error occurs particularly often when the rolling bearing is a floating bearing is designed, so as a bearing that is displaceable in the axial direction.
an hat schon dadurch Abhilfe zu schaffen versucht, daß man statt eines Loslagers ein Festlager eingebaut hat.an has already tried to remedy the situation by instead of one Has installed a fixed bearing in the floating bearing.
Dabei ist es aber schwierig, den Festsitz über den gesanDen im Betrieb vorkommenden Temperaturbereich zu gewährleisten, ohne daß das Lagerspiel beeinträchtigt wird.But it is difficult to get the tight fit over the sand in the company to ensure occurring temperature range without affecting the bearing play will.
Vorteile der Erfindung Die erfindungsgemäße Lagernabe mit den kennzeichnenden Merkmalen des Hauptanspruchs hat demgegenüber den Vorteil, daß das federnde Element das Wälzlager über den gesamten vorkommenden Temperaturbereich festhält. Dadurch wird erreicht, daß bei niedrigen Betriebstemperaturen keine zu hohen radialen Kräfte auf das Wälzlager wirken und so das Lagerspiel beeinträchtigen und daß auch bei hohen Betriebstemperaturen ein fester Sitz des Lagers in der Lagerbüchse gewährleistet ist.Advantages of the invention The bearing hub according to the invention with the characterizing Features of the main claim has the advantage that the resilient element the roller bearing holds over the entire occurring temperature range. Through this it is achieved that at low operating temperatures no excessive radial forces act on the roller bearing and so affect the bearing play and that also with A tight fit of the bearing in the bearing bush is guaranteed at high operating temperatures is.
Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen der im Hauptanspruch angegebenen Lagernabe möglich.The measures listed in the subclaims are advantageous Further developments and improvements to the bearing hub specified in the main claim are possible.
Besonders einfach ist die Ausführung des federnden Elements als Blechstreifen mit Sicken. Ein solcher Blechstreifen ist einfach herzustellen und kann leicht in die Lagerbüchse eingelegt werden. Ist die Lagerbüchse mit einer Nut versehen, so wird der Blechstreifen in der Lagerbüchse sicher gehalten. Auch die Montage des Wälzlagers selbst in der Lagerbüchse wird vereinfacht, weil in -. manchen Fällen im Lagersitz komprimierte Luft durch die Lücken des federnden Elements entweichen kann.The design of the resilient element as a sheet metal strip is particularly simple with beads. Such a sheet metal strip is easy to manufacture and can easily be in the bearing bush is inserted. If the bearing bush is provided with a groove, so the sheet metal strip is held securely in the bearing bush. The assembly of the Rolling bearing itself in the bearing bush is simplified because in -. In some cases, air compressed in the bearing seat through the gaps in the resilient element can escape.
Die erfindungsgemäße Lagernabe hat noch weitere Vorteile. Bei niedrigen Temperaturen wird im Gegensatz zu herkömmlichen Lagern die Lagerluft eingeengt und damit eine übermäßige Geräuschbildung vermieden. Durch die Wirkung des federnden Elements schlägt die Lagerbüchse nicht aus. Die Herstellung der Lagernabe wird dadurch kostengünstiger, das bei der Lagerbüchse gröbere Tole-@ansen zugelassen werden können. Wegen der Ausbildung des federnden Elements als Blechstreifen mit Sicken, die in der Längsrichtung der Maschinenwelle verlaufen, wird in vorteilhafter Weise eine Flächenberührung erreicht und nicht - wie bei herkömmlichen Lösungen mit Ringen -lediglich eine Linienberührung. Schließlich ist der Einsatz der erfindungsgemäßen Lagerbüchse dann besonders vorteilhaft, wenn das Wälzlager und die Nabe aus Materialien mit unterschiedlichen Wärmeausdehnungs-Koeffizienten bestehen.The bearing hub according to the invention has other advantages. At low Temperatures, in contrast to conventional bearings, the bearing air is restricted and this avoids excessive noise. Through the effect of the resilient Elements does not knock out the bearing bush. The production of the bearing hub is thereby cheaper, that coarser Toleansen can be approved for the bearing bush. Because of the design of the resilient element as a sheet metal strip with beads that are in run in the longitudinal direction of the machine shaft, is advantageously a Surface contact achieved and not - as with conventional solutions with rings -just a line contact. Finally, the use of the invention Bearing bush is particularly advantageous when the roller bearing and the hub are made of materials with different coefficients of thermal expansion.
