Wälzlager axt schwach gewölbter Bohrangs- und MantelflächeRolling bearing ax slightly curved drill bit and lateral surface

Gegenstand der !feuerung ist sin Wälzlager» dessen Bohrungs- -and lantelflächen in Richtung der Lagerdrehaehse schwach, gewölbt sind, und zwar derart, daß die Mitte der Sohrungs- bzw· Mantelfläche im Gegenstück» d. h.. der Welle oder dem Gehäuse, aufliegt, die "beiden Snden der üächen jedoch, entsprechend der "WoI-"bung sich, -iron der zylindrischen SLaehe des Segenstüeks entfernen.The object of the fire is the rolling bearing, whose bore and lateral surfaces in the direction of the Lagerdrehaehse weak, arched, in such a way that the Center of the socket or jacket surface in the counterpart »d. h .. the wave or the Housing, rests, the "two ends of the surface, however, according to the" WoI "exercise -iron of the cylindrical surface near the blessing piece.

Grundsätzlich, läßt sich, die !feuerung für alle !Eislager verwenden, sie ist jedoch besonders für Sadiallager geeignet. Me Sraeugesde der gewölbten Bohrungs- tzw. ^tntelfläche kann sowohl gleichmäßig als auch Tersehieden stark gekrümmt sein, wie es schließlich, auch möglieh. ist, den Mittelteil der Bohruags- "bzw.

In allen Fällen moß die Erzetigende eine wenigstens angenähert den Gesetzen der elastischen Spannung folgende Linie sein.Basically, the! Fire can be used for all! Ice camps, but it is particularly suitable for radial camps. Me Sraeugesde of the arched Bohrungstzw. The central surface can be both uniformly and laterally strongly curved, as it is ultimately possible. is to make the middle part of the Bohruags- "or Ifiantelfläche cylindrical, and to arch the surfaces towards the harvests" bssr. bevel. In all cases the producing line must at least approximately follow the laws of elastic tension.

In der Zeichnung ist Jbb. 1 ein Wälzlagerquerschnitt» bei dem die Bohrung a "and der-Mantel "b durchgehend gewölbt sind.. Abb. 2 ist ein "Wälzlagercpierschnitt, "bei dem sowohl die Bohrung als axtch. der Mantel im Mittelteil c der ELäche zylindrisch, ausgebildet voaä. nur gegen die Enden d hin gewölbt "bzw. abgeschrägt: sind.

In der Zeichnung ist die "Wölbung wegen der besseren Sichtbarmachung stark übertrieben dargestellt.In the drawing, Jbb. 1 is a roller bearing cross section in which the bore a "and the jacket" b are continuously curved. Fig. 2 is a "roller bearing cross section" in which both the bore and axtch. the jacket in the middle part c of the surface is cylindrical, formed voaä. only arched towards the ends d "or beveled: are.
