Description

Die Erfindung betrifft eine Wälzlageranordnung, bei der zwei Wälzlager durch Blechmäntel zu einer Nabe vereinigt sind, die zur Lagerung drehender Maschinenteile in Bohrungen oder auf feststehenden Zapfen, Achsen oder Wellen vielseitig verwendbar ist. Die Wälzlager sitzen hierbei zwischen zwei Blechmänteln, die einmal den Sitz für die inneren bzw. für die äußeren Lagerringe bilden und andererseits zur Befestigung der Anordnung in einer Lagerbohrung bzw. zur Befestigung der Nabe auf einem Zapfen, einer Achse oder einer Welle dienen. Um den gewünschten Sitz der Nabe in der Bohrung oder auf dem Zapfen oder der Welle zu erreichen, muß der Durchmesser der Bohrung bzw. der des Zapfens oder der Welle .sehr genau, also mit sehr kleiner Toleranz, :hergestellt werden. Es ist aber bekannt, daß die Kosten für die Herstellung einer Bohrung oder eines Zapfens bzw. einer Welle unverhältnismäßig stark ansteigen, wenn die Toleranzen eng begrenzt sind. Außerdem sind viele Werkstätten nicht in der Lage, Toleranzen unterhalb gewisser Werte einhalten zu können. Es wäre daher für die Verwendung von nabenförmigen Wälzlageranordnungen ein wesentlicher Vorteil, wenn die Durchmesser der die Nabe aufnehmenden Teile mit geringer Toleranz hergestellt werden können.The invention relates to a roller bearing arrangement in which two roller bearings are united by sheet metal jackets to form a hub, which is used to support rotating machine parts Versatile use in bores or on fixed journals, axles or shafts is. The roller bearings sit between two sheet metal jackets, which once have the seat for the inner and outer bearing rings and on the other hand for fastening the arrangement in a bearing bore or for fastening the hub on a journal, serve as an axis or a shaft. To the desired seat of the hub in the bore or on the pin or the shaft must be the diameter of the hole or that of the journal or the shaft .very accurate, i.e. with a very small tolerance, :getting produced. However, it is known that the cost of making a Bore or a pin or a shaft increase disproportionately if the tolerances are tightly limited. In addition, many workshops are unable to To be able to adhere to tolerances below certain values. It would therefore be for use of hub-shaped roller bearing assemblies a significant advantage when the diameter of the parts receiving the hub can be manufactured with a low tolerance.

Um dies zu ermöglichen, sind erfindungsgemäß ein oder beide Blechmäntel der Nabe in radialer Richtung federnd ausgebildet, und zwar in der. Weise, daß die Blechmäntel längs des Umfanges in radialer Richtung gewellt sind oder axial laufende Sicken aufweisen. Bei dieser Ausbildung der Naben genügt es, wenn der Durchmesser der Bohrung einen Größtwert und der des Zapfens oder der Welle einen Kleinstwert nicht unterschreitet, und wenn dieser Wert mit üblich großer Toleranz eingehalten wird. Die Abweichungen vom Sollmaß werden durch die radiale Federung der Blechmäntel ausgeglichen.In order to make this possible, according to the invention, one or both sheet metal jackets are provided the hub is resilient in the radial direction, namely in the. Way that the Sheet metal jackets are corrugated along the circumference in the radial direction or axially running Have beads. With this design of the hubs it is sufficient if the diameter the bore a maximum value and that of the journal or the shaft a minimum value does not fall below, and if this value is adhered to with the usual large tolerance will. The deviations from the nominal size are caused by the radial springing of the sheet metal jacket balanced.

Ein weiterer Vorteil der nabenförmigen Wälzlageranordnung gemäß der Erfindung ist, daß der Reibungsdruck durch die radiale Federung ständig aufrechterhalten bleibt, und daß ein etwaiges Lagerspiel ausgeglichen wird. Es ist auch nicht mehr notwendig, Lager mit Vorweiten verwenden zu müssen. Auch können Naben gemäß der Erfindung in Metallteilen befestigt werden; die andere Ausdehnungskoeffizienten als Stahl besitzen, da die Differenz der Ausdehnungskoeffizienten ebenfalls durch die radiale Federung ausgeglichen wird.Another advantage of the hub-shaped roller bearing arrangement according to FIG Invention is that the frictional pressure is constantly maintained by the radial suspension remains, and that any bearing play is compensated. It is also no more necessary to have to use bearings with forward widths. Hubs according to the Invention to be attached in metal parts; the other coefficient of expansion than steel, because the difference in expansion coefficients is also due the radial suspension is compensated.

Zwei Ausführungsbeispiele der Erfindung sind im folgenden an Hand der Zeichnung beschrieben, die nabenförmige Wälzlageranordnungen mit zwei Halbsahulterkugellagern zeigt, und zwar zeigt Abb. i einen Längsschnitt durch die Anordnung, Abb. 2 einen Querschnitt nach Linie 11-II der Abb, i und Abb. 3 einen Längsschnitt durch eine Anordnung ähnlich Abb. i, wobei an Stelle des äußeren Blechmantels der innere radial federnd ausgebildet ist. Die inneren Lagerringe oder Lagerkonusse i sitzen fest auf einem Blechmantel oder Rohr 2, das an den Enden als Widerlager für die Lagerringe i dienende Umbördelungen 3 aufweist, wobei zwischen den Umbördelungen und den Lagerringen Blechringe 4 eingepreßt sind, die als Staubschutz für das Lager dienen. Die Kugeln beider Lager sind mit S und ihre äußeren Lagerringe mit 6 bezeichnet. Diese sitzen in einem Blechmantel?, der in Verbindung mit den Flanschen 8 der Lagerringe 6 beider Lager axial gegeneinander festlegt.Two exemplary embodiments of the invention are given below Described in the drawing, the hub-shaped rolling bearing assemblies with two half-half shoulder ball bearings shows, namely Fig. i shows a longitudinal section through the arrangement, Fig. 2 shows a Cross section along line 11-II of Fig, i and Fig. 3 is a longitudinal section through a Arrangement similar to Fig. I, with the inner one being radial instead of the outer sheet metal jacket is designed to be resilient. The inner bearing rings or bearing cones i are tight on a sheet metal jacket or tube 2, which acts as an abutment for the bearing rings at the ends i serving flanges 3, wherein between the flanges and the bearing rings Sheet metal rings 4 are pressed in, which serve as dust protection for the camp. The balls both bearings are designated with S and their outer bearing rings with 6. These sit in a sheet metal jacket? which, in conjunction with the flanges 8 of the bearing rings 6 of both Axially fixed bearing against each other.

Der äußere Blechmantel ? ist, wie auch Abb. 2 zeigt, an den Stellen 9 längs des Umfanges eewel'lt ausgeführt, wobei die Wellenteilung und die Wellenhöhe in Verbindung mit den federnden Eigenschaften des Werkstoffes die radiale Federung bestimmen. In der Regel besteht der Blechmante17 aus gut federndem und gegebenenfalls gehärtetem Stahlblech. Bei kürzeren Naben genügt eine Wellung zwischen den beiden Lagern.The outer sheet metal jacket? is, as Fig. 2 also shows, at the points 9 running along the circumference eewel'lt, the wave pitch and the wave height in connection with the resilient properties of the material, the radial suspension determine. As a rule, the sheet metal jacket17 consists of well-resilient and possibly hardened sheet steel. With shorter hubs, a corrugation between the two is sufficient To store.

Bei dem Ausführungsbeispiel nach Abb. 3 ist der innere Blechmantel io unterhalb der Lagerringe i gewellt ausgebildet, während der äußere Blechmantel i i glatt ausgeführt ist. Es können auch im Bedarfsfalle beide Blechmäntel radial federnd ausgebildet sein.In the embodiment according to Fig. 3, the inner sheet metal jacket io underneath the bearing rings i formed corrugated, while the outer sheet metal jacket i i is executed smoothly. If necessary, both sheet metal jackets can also be used radially be resilient.

Statt des inneren Blechmantels 2 kann gegebenenfalls auch ein voller Zapfen für den Aufbau der Wälzlageranordnung verwendet werden, wobei in der Regel dieser Zapfen einen Gewindeansatz zur Befestigung an anderen Maschinenteilen tragen wird. In diesem Falle sind am Zapfen 6 Widerlager angebracht, die die Umbördelungen 3 ersetzen. Ebenso ist es umgekehrt möglich, die äußeren Lagerringe unmittelbar in der Bohrung eines Maschinenteiles zu montieren und die Lager hierin nachträglich durch den inneren Blechmantel festzulegen, da eine der Umbördelungen 3 nach dem Einbau des Lagers hergestellt werden kann.Instead of the inner sheet metal jacket 2, a full one can optionally also be used Spigots are used to build the rolling bearing assembly, usually this pin has a threaded attachment for attachment to other machine parts will. In this case 6 abutments are attached to the pin that form the flanges 3 replace. Conversely, it is also possible to use the outer bearing rings directly to be mounted in the bore of a machine part and the bearings therein afterwards set by the inner sheet metal jacket, as one of the flanges 3 after Installation of the bearing can be made.
