Zur Verbesserung der bisher bekannten Befestigungen für Lüfterräder v/ird neuerungsgemäß für Lüfterräder, bei denen zumindest die Fabe aus elastischem Material besteht, vorgeschlagen, daß die JTabenbohrung eine Querschnittsverengung aufweist, die so bemessen ist, daß .sie sich beim Aufschieben~des Lüfterrades auf die Welle auf den Wellendrarchmesser erweitert, und daß die Querschnittsverengung beim richtigen Sitz des Lüfters in die Vertiefung eingreift. Dabei können sowohl die Querschnittsverengung in der Uabenbohrung als auch die Vertiefungen in der Welle verschiedenartig" ausgeführt werden. Es ist z.B. denkbar, die Querschnittsverengung nicht am ganzen Bohrungsumfang gleichmäßig, sondern z,B, klauenförmig auszuführen, doch kann sie, vorallem wenn kleinere Drehmomente zu übertragen sind, auch ringförmig sein, wobei die Welle dann ebenfalls eine ringförmige Vertiefung aufweisen müßte.To improve the previously known fastenings for fan wheels v / ird according to the innovation for fan wheels, where at least the Fabe from consists of elastic material, proposed that the JTabenbohrung a Has cross-sectional constriction, which is dimensioned so that .sie when Pushing ~ the fan wheel onto the shaft on the shaft rotor knife extended, and that the cross-sectional constriction engages in the recess when the fan is properly seated. Both the cross-sectional constriction in the hub bore as well as the indentations in the shaft are designed in various ways. It is e.g. conceivable that the Cross-sectional constriction should not be carried out uniformly over the entire circumference of the bore, but rather in a claw-shaped manner, but it can, especially if Smaller torques are to be transmitted, also be ring-shaped, in which case the shaft would also have to have an annular recess.
