Description

Seelake

Die Erfindung betrifft einen Käfig für Rollenlager, welcher aus einem mit seitlichen Bohrungen zur Aufnahme der Rollen versehenen und einem das offene Ende der Bohrungen abschließenden Deckring besteht.The invention relates to a cage for roller bearings, which consists of a cage with side bores provided for receiving the rollers and one closing the open end of the bores Cover ring consists.

Derartige bekannte, durch Abb. ι und 2 im Quer- und Längsschnitt veranschaulichte Führungskäfige weisen infolge der beiderseitigen Einfassung der "Wälzrolle durch die diesen angepaßten Verbindungsstege den Nachteil auf, daß eine im Revisionsfalle oder aus anderen Gründen erforderliche Demontage ein Lösen sämtlicher Nietverbindungen bedingt.Such known, illustrated by Fig. Ι and 2 in cross and longitudinal section guide cages point due to the mutual edging of the "rolling roller by these adapted Connecting webs have the disadvantage that one in the case of revision or for other reasons required dismantling requires loosening of all riveted connections.

Diesen Übelstand behebt der Erfindungsgegenstand durch Erweiterung der Bohrungen gegen die äußere Lauffläche hin derart, daß die Rollen in radialer Richtung in den Ring eingelegt und aus ihm herausgenommen werden können und daß der Ring von einem Stahlband mit Ausschnitten von solcher Größe umspannt ist, daß die durch die Ausschnitte ragenden Rollen gegen Herausfallen gesichert sind.The subject of the invention remedies this drawback by enlarging the bores against the outer running surface in such a way that the rollers are inserted into the ring in the radial direction and can be removed from it and that the ring spanned by a steel band with cutouts of such size is that the roles protruding through the cutouts are secured against falling out.

Sowohl Ein- und Ausbringung von Wälzkörpern in radialer Richtung als Umspannung eines Führungskäfigs sind an sich bekannt, aber nicht in ihrer erfindungsgemäßen besondersartigen Zusammenwirkung.Both the insertion and removal of rolling elements in the radial direction as reclamping a guide cage are known per se, but not in their particular type according to the invention Cooperation.

Die Zeichnung zeigt außer der erwähnten bekannten Einrichtung nach Abb. 1 und 2 eine Ausführungsform des Erfindungsgegenstandes (Abb. 3 und 4) mit federndem Verschlußring, während letzterer bei der Ausführungsform nach Abb. 5, 6, 7, 8 durch Verschraubung überstehender Lappen zusammengehalten wird.The drawing shows in addition to the known device according to Fig. 1 and 2 mentioned Embodiment of the subject matter of the invention (Figs. 3 and 4) with resilient locking ring, while the latter in the embodiment according to Fig. 5, 6, 7, 8 protruding by screwing Rag is held together.

Es bezeichnet a, einen glatten, durch Nieten b mit dem Stegringe verbundenen Ring des Rollenlagerkäfigs. Die Stege i des letzteren weisen nur in ihrer unteren Hälfte der Rundung der Rollen e angepaßte Rundungen f auf, oberhalb der Mittelebene dagegen tangential zum Rollenquerschnitt verlaufende gerade Flächen g. Letztere ermöglichen Ein- und Ausbringen der Rollen e, während ein Ausfallen derselben durch einen Stahlring Ä verhindert wird. Dieser ist beim Ausführungsbeispiel Abb. 3 und 4 als federnd auf den Ringen α und c des Rollenführungskäfigs aufliegend gedacht, unter Zusammenstoß seiner Enden beispielsweise bei i. It denotes a, a smooth ring of the roller bearing cage connected to the leg rings by rivets b. The webs i of the latter have only the bottom half of the rounding of the rolls e f curves matched to above the mid-plane, however, tangential to the roller cross-section straight g faces. The latter enable the rollers e to be brought in and out, while a steel ring Ä prevents them from falling out. In the exemplary embodiment Fig. 3 and 4, this is intended to rest resiliently on the rings α and c of the roller guide cage, with its ends colliding, for example at i.

Statt dessen kann dieser Abschlußring insbesondere für größere Ausführungen mit den inneren Käfigringen a, 0 durch eine Schraube k fest verbunden werden. Diese wird zweckmäßig durch eine der Nietbohrungen 1 der Ringe α und c hindurchgeführt in der Weise, daß Kopf und Mutter die sich überlappenden Enden m und η des Ringes h überdecken. Eine durch eine Zunge 0 undrehbare Unterlagscheibe fi kann zur erforderlichen Sicherung gegen Lockerung vorgesehen werden.Instead, this closing ring can be firmly connected to the inner cage rings a, 0 by a screw k, especially for larger designs. This is expediently passed through one of the rivet holes 1 of the rings α and c in such a way that the head and nut cover the overlapping ends m and η of the ring h. A washer fi, which cannot be rotated by a tongue 0, can be provided as a necessary safeguard against loosening.

Es bedarf kaum der besonderen Feststellung, daß der Abschlußring auch innen vorgesehen sein kann bei entsprechend umgekehrter Anordnung der tangentialen, den Rollendurchlaß ermöglichenden Teile der Rollenführungsstege.It hardly needs to be stated in particular that the locking ring is also provided on the inside can be with a correspondingly reversed arrangement of the tangential, the roller passage enabling parts of the roller guide webs.
