Description

Die Erfindung betrifft einen federnden Einbauring für eine Lagernabe nach der Gattung des Hauptanspruchs.The invention relates to a resilient mounting ring for a bearing hub according to the preamble of the main claim.

Aus der GB-PS 6 47 187 ist ein federnder Einbauring dieser Art bekannt, bei welchem die quer zur Längsrichtung des Federblechstreifens verlaufenden Schnitte jeweils an den zusammenhängend verbleibenden beiden Randzonen endigen und die zwischen jeweils zwei Schnitten verbleibenden Flächenteile beim Einrollen des zunächst ebenen Blechstreifens diesem eine polygonale Form geben sollen. Beim Einbau des Federblechstreifens legen sich die unmittelbar an die Schnitte angrenzenden Flächenteile an die Bohrungwand der Nabe an, wobei die Mittelzone der federelastisch verformten, zwischen zwei Schnitten liegenden Flächen sich auf dem Außenring des Kugellagers abstützt. Die radialen Verspannungskräfte sind bei dieser bekannten Ausbildung eines federnden Einbauringes nicht nur von den Federeigenschaften des Materials abhängig, sondern auch vom gegenseitigen Abstand der Einschnitte und dem Durchmesser des Außenrings.From GB-PS 6 47 187 a resilient mounting ring of this type is known in which the transverse to the longitudinal direction of the spring steel strip running cuts in each case on the remaining two contiguous Edge zones end and the surface parts remaining between each two cuts when curling of the initially flat sheet metal strip should give it a polygonal shape. When installing the spring steel strip the surface parts immediately adjacent to the cuts lie against the bore wall of the hub on, with the middle zone of the resiliently deformed surfaces lying between two cuts on the Outer ring of the ball bearing is supported. The radial tension forces are in this known training a resilient mounting ring not only dependent on the spring properties of the material, but also on the mutual spacing of the incisions and the diameter of the outer ring.

Zur Erweiterung des Toleranzbereichs beim Einbau von Kugellagern sind weitere Einbauringe bekannt (z. B. durch die DE-PS 8 51 865, Konstruktion 26, 1974, Seite 251 bis 260), bei welchem federnde Sicken bzw. Einprägungen vorgesehen sind. Diese führen jedoch dazu, daß der Einbauring an den Flächen des Lagers bzw. der Einbauöffnung lediglich linienförmig aufliegt. Außerdem ist bei den bekannten Einbauringen durch die Art der Verformung derselben eine genaue Dosierung der Einpreßkraft schwierig zu erreichen.Additional mounting rings are known to expand the tolerance range when installing ball bearings (e.g. by DE-PS 8 51 865, construction 26, 1974, pages 251 to 260), in which resilient beads or Embossings are provided. However, these lead to the mounting ring on the surfaces of the bearing or the installation opening only rests linearly. In addition, the known mounting rings by the Type of deformation of the same to achieve an exact dosage of the press-in force difficult.

Der Erfindung liegt die Aufgabe zugrunde, einen federnden Einbauring so auszubilden, daß die radialen Verspannkräfte leichter beherrschbar sind und der Einbauring leicht in den Lagersitz eingesetzt werden kann und dann in einfacher Weise den axialen Einschub des Wälzlageraußenringes ermöglicht.The invention is based on the object of a resilient To design the mounting ring so that the radial bracing forces are easier to control and the mounting ring can easily be inserted into the bearing seat and then in a simple manner the axial insertion of the Rolling bearing outer ring allows.

Zur Lösung dieser Aufgabe sind erfindungsgemäß die im kennzeichnenden Teil des Patentanspruchs 1 angegebenen Maßnahmen vorgesehen.To solve this problem, those specified in the characterizing part of claim 1 are according to the invention Measures planned.

Durch die in radialer Richtung gemessene Höhe der Sicken gegenüber den beim Stanzvorgang unverformt bleibenden Flächenteilen kann die Verspannkraft so eingestellt werden, daß bei den in Betrieb vorkommenden niedrigsten Temperaturen das Wälzlagerspiel bis zu den höchsten im Betrieb vorkommenden Temperaturen ausreichend gewährleistet ist. Ferner hat der erfindungsgemäße Einbauring den Vorteil, daß er auch an der Oberfläche des Lage! sitzes flächenhaft aufliegt.Due to the height of the beads measured in the radial direction, they are not deformed during the punching process remaining surface parts, the tensioning force can be adjusted in such a way that in the case of those that occur in operation lowest temperatures, the rolling bearing clearance up to the highest temperatures occurring during operation is sufficiently guaranteed. Furthermore, the mounting ring according to the invention has the advantage that it is also on the surface of the location! seat rests flat.
