Description

Die Erfindung betrifft eine Lagerbuchse für ein selbst einstellhares kugeliges Lager, insbesondere für Lüfter. Bei kleinen Motoren mit verhältnismäßig starker Welle, namentlich bei Motoren, wie man sie bei Kühlschrankfädhern u. dgl. verwendet, ist die Lagerreibung mitunter so groß, .daß Schwierigkeiten beim Anlaufen auftreten.The invention relates to a bearing bushing for a self-adjustable hinge spherical bearing, especially for fans. For small engines with relatively strong wave, especially in motors, as they are in refrigerator pullers and the like. is used, the bearing friction is sometimes so great that there are difficulties when starting appear.

Gemäß der Erfindung werden diese Nachteile vermieden, wenn man eine Lagerbuchse mit selbst einstellbarem kugeligem Lager in der Weise ausbildet, daß die eine Lagerschale aus Spritzguß besteht und in ihrer Mitte ,die Lagerkugel aufnimmt, während die Gegenschale aus einer gepreßten Blechhülse gebildet ist, die mittels eines Halteringes auf an. der Lagerschale angegossene Nietzapfen aufgenietet ist.According to the invention, these disadvantages are avoided if one Bearing bush with self-adjustable spherical bearing in such a way that the one bearing shell is made of injection molding and in its middle, the bearing ball receives, while the counter shell is formed from a pressed sheet metal sleeve, which means a retaining ring on. the bearing shell cast rivet pin is riveted on.

In der Zeichnung ist ein, Ausführungsbeispiel dargestellt.In the drawing, an embodiment is shown.

Fig. i zeigt einen Schnitt durch eine neue Lagerbuchse und Fig. 2 eine Draufsicht auf die Lagerbuchse nach Fing. i nach Fortnahme .des Deckels.FIG. I shows a section through a new bearing bush and FIG. 2 a top view of the bearing bush after fing. i after removing the cover.

Wie man aus Fig. i ersieht, befindet sich in der aus Spritzguß bestehenden Lagerschale i eine Lagerkugel 2, durch welche die Welle des Motors (nicht dargestellt) hindurchgeführt ist. Auf der Lagerschale liegt ein Ölfilz 3, der die Ölrinnen 4 überdeckt. Auf die Lagerkugel z ist =die-hutförmige Gegenschale 5 aufgesetzt, über deren auf dem Ölfile 3 ruhenden: Flansch 6 der Haltering 7 gelegt ist. Das Lagergehäuse i ist überdeckt von dem Deckel 8. Im Rande des Deckels 8 ist ein Loch 9 vorgesehen, in welches die unter dem Druck der Feder io stehende Kugel ii eingreift. Bei 12 ist ein Dichtungsring angedeutet.As can be seen from FIG. I, in the injection-molded bearing shell i there is a bearing ball 2 through which the shaft of the motor (not shown) is passed. An oil felt 3, which covers the oil channels 4, lies on the bearing shell. The hat-shaped counter-shell 5 is placed on the bearing ball z, over the flange 6 of which the retaining ring 7 is placed, resting on the oil file 3. The bearing housing i is covered by the cover 8. In the edge of the cover 8 a hole 9 is provided, into which the ball ii, which is under the pressure of the spring io, engages. At 12 a sealing ring is indicated.

Die neue Lagerbuchse bietet .den Vorteil, daß die Haltevorrichtung für idias Lager gleichmäßig leicht federt. Dies wird namentlich dadurch erreicht, d'aß der Haltering 7 aus Bandstahl besteht. Die als Gegenlager dienende Lagerfahne 5 besteht aus Tiefziehblech.The new bearing bush offers the advantage that the holding device for idias bearings evenly and lightly springs. This is achieved in particular by d'ass the retaining ring 7 is made of steel strip. The bearing flag serving as a counter bearing 5 consists of deep-drawn sheet metal.
