bearing holes in the axial direction, for example
by drilling or punching, whose diameter
are at least a little larger than the diameter of the
axes to be inserted so that they can be inserted easily. The
Axles are then, for example, punched on the circumference of the
bearing hole, by adding a groove to the axle and
Holding this groove by suitable spring Sf

Fig. 3 den vergrösserten Querschnitt eines Lagers.Fig. 3 shows the enlarged cross-section of a bearing.
Die Fig. 1 zeigt ein Beispiel für ein einziges Achslager 1 nach der Neuerung. Das Lager besteht aus einem als fester Teil dienendem Gehäuseteil 2 und einem gegen dieses durch Einsetzen dVr in der Fig. 1 nicht gezeichneten Achse in das Lager radial zur Achse sich elastisch verspannenden Teil des Gehäuses/ hier einem Steg 3. Im Beispiel ist diesier durch einen Spalt 4, der ihn auf drei Seiten umgibt, vom Gehäuse getrennt. Beim Einsetzen der Achse in das Achslager 1 erleidet er durch die in Richtung eines Kraftpfeils 6 wirkende Verspannung die in der Fig. 1 strich-punktiert gezeichnete elastische Verformung 5. In den Gehäuseteil 2 und den Steg 3 ist jeweils ein Ausschnitt eingeschnitten, die zusammen das Achslager 1 bilden. Bei geeigneter Formgebung dieses Ausschnitts wird die in das Achslager 1 eingeführte Achse durch die Rückwirkung der Verspannung des Stegs 3 gegen das Gehäuseteil 2 so festgehalten, dass sie sich weder in axialer noch in Umfangsrichtung von selbst bewegen kann. Die Achse ist somit eine feststehende Achse. Die zur Herstellung des Lagers notwendigen Ausschnitte aus der Gehäusewand können bei geeigneter Formgebung durch Stanzen in einem einzigen Arbeitsvorgang hergestellt werden.Fig. 1 shows an example of a single axle bearing 1 according to the innovation. The bearing consists of a housing part 2 which serves as a fixed part and a part of the housing/in this case a web 3 which is elastically braced against this by inserting the axle (not shown in Fig. 1) into the bearing radially to the axle. In the example, this is separated from the housing by a gap 4 which surrounds it on three sides. When the axle is inserted into the axle bearing 1, it undergoes the elastic deformation 5 shown in dash-dotted lines in Fig. 1 due to the bracing acting in the direction of a force arrow 6. A cutout is cut into the housing part 2 and the web 3, which together form the axle bearing 1. If this cutout is suitably shaped, the axle inserted into the axle bearing 1 is held in place by the reaction of the bracing of the web 3 against the housing part 2 in such a way that it cannot move on its own in either the axial or circumferential direction. The axle is therefore a fixed axle. If suitably shaped, the cutouts in the housing wall required to produce the bearing can be made by punching in a single operation.

Die Fig. 3 stellt ein Achslager &iacgr; dar, in das eine Achse 7 eingesetzt ist. Die Auschnitte aus dem Gehäuseteil 2 und dem als sich verspannenden Teil dienenden Steg 3, die das Achslager 1 bilden, weisen Ecken 8 auf, weiche die Achse 7 festhalten. In dem dargestellten Beispiel sind die Ausschnitte Teilkreise, deren winkeiöereiehe kleiner als bei einem Halbkreis/ sind und deren Radien etwas kleiner als der Radius der Achse 7 ist.Fig. 3 shows an axle bearing ‘, into which an axle 7 is inserted. The cutouts from the housing part 2 and the web 3 serving as the bracing part, which form the axle bearing 1, have corners 8 which hold the axle 7 in place. In the example shown, the cutouts are partial circles whose angular range is smaller than that of a semicircle and whose radii are slightly smaller than the radius of the axle 7.
Das beschriebene Lager kann in einem einzigen Stanzvorgang hergestellt werden und bedarf zur Festlegung der Achse 7 keiner zusätzlichen Befestigungsteile. Sie kann somit preisgünstiger hergestellt werden als die bekannten Lager.The bearing described can be manufactured in a single punching process and does not require any additional fastening parts to fix the axis 7. It can therefore be manufactured more cheaply than the known bearings.
