Description

Der Erfindungsgegenstand bedeutet für die Herstellung von Massivfensterkäfigen einen bedeutenden Fortschritt. Bis jetzt mußten bei den Massivfensterkäfigen die Taschen zuerst ausgebohrt, dann in rechteckige Form ausgestoßen und dann geräumt werden. Diese verschiedenen Arbeitsgänge werden dann sehr vereinfacht, wenn erfindungsgemäß der Massivkäfig an der Stelle, wo die Käfigtaschen sitzen, so weit ausgedreht wird, daß der nach dem Ausdrehen übrigbleibende dünne Querschnitt ein Stanzen des Käfigs zuläßt. Der Käfig erhält damit etwa U-Form. Da nunmehr die Höhe der Käfigtaschen sehr gering ist, so ist es meist angebracht, ein an sich bekanntes Halteband um oder in den Käfig zu legen, das außer den Aussparungen für die Rollen mit Lappen versehen ist, durch welche die Rolle nach dem. Zurückbiegen auf der einen Laufbahn gehalten wird, ohne im Betrieb die Rollen zu berühren.The subject of the invention means for the production of solid window cages a significant advance. Until now the massive window cages had to Pockets first drilled out, then ejected into a rectangular shape and then cleared will. These various operations are then greatly simplified when in accordance with the invention the solid cage is turned out at the point where the cage pockets are located, that the thin cross-section remaining after the turning is a punching of the cage allows. The cage is thus approximately U-shaped. Since now the height of the cage pockets is very low, so it is usually appropriate to use a known retaining strap or to put it in the cage, except for the recesses for the rolls with rags is provided, through which the role after. Bending back on one track is held without touching the rollers during operation.

In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt. Abb. t zeigt den Käfig a im Querschnitt, er ist von innen her ausgedreht, so daß die Werkstoffstärke bei den Käfigtaschen b so gering ist, daß ein Stanzen der Taschen möglich ist. Die Käfigtaschen werden nach oben durch ein Halteband c geschlossen, das mit Lappen d versehen ist. Abb. 3 zeigt den Käfig von außen gesehen. In den Käfigmantel sind Nuten e eingearbeitet. In diese Nuten wird das Halteband c gedrückt und dadurch in Achs- und Umfangsrichtung gehalten. Abb. ¢ zeigt die Stoßstelle g des Haltebandes, die zusammengeschweißt ist.The drawing shows an embodiment of the subject matter of the invention shown. Fig.t shows the cage a in cross section, it is turned from the inside, so that the material thickness in the cage pockets b is so small that punching the pockets is possible. The cage pockets are held up by a retaining strap c closed, which is provided with tab d. Fig. 3 shows the cage seen from the outside. Grooves e are incorporated into the cage jacket. The retaining strap is placed in these grooves c pressed and thereby held in the axial and circumferential directions. Fig. ¢ shows the joint g of the tether that is welded together.

Die gezeichnete Ausführung zeigt einen Käfig für Innenbordlager. Bei Außenbordlagern, bei denen am Außenring 2 feste Borde sind, wird der Käfig am Mantel ausgedreht und das Halteband in die Bohrung des Käfigs eingebracht.The drawn version shows a cage for inboard bearings. at Outboard bearings in which there are 2 fixed ribs on the outer ring, the cage on the shell unscrewed and inserted the retaining strap into the hole in the cage.
