Verfahren zur Erzeugung eines gewölbten Profils am Kranze von Blechriemscheiben.
Die Erfindung betrifft ein Verfahren zur Erzeugung eines gewölbten Profils am Kranze von Blechriemscheiben, welcher mit nach innen abgebogenen Flanschen zum Festspannen des Kranzes auf einem Armkreuz versehen ist. Wenn man solchen Kränzen ein gewölbtes 'Profil geben will, so verhindern die Flanschen die zunächstliegenden Teile des Kranzes, das gewölbte Profil anzunehmen. Das neue Verfahren, dass diese Schwierigkeiten beseitigt, besteht darin, dass die Verbindungsflanschen vor dem Pressen des Kranzes auf gewölbtes Profil gefaltet oder aufgeschlitzt werden, so dass sie es den den Flanschen am nächsten liegenden Teilen des Kranzes gestatten, das gewölbte Profil anzunehmen. Wenn die Verb : ndungsflanschen hierbei gefaltet oder gewellt, also nicht aufgeschlitzt werden, so erhält der Kranz schon hierdurch eine gewisse Wölbung in der Nähe der Verbindungsflanschen.
Nach dem Falten der Verbindungsflanschen wird der Kranz zu der richtigen Krümmung gebogen und schliesslich in ein Biegewerkzeug eingeführt und auf die gewünschte Form
EMI1.1
den Falten aufgenommen.
Die Fig. i und 2 der Zeichnung sind die Seiten-bzw. Endansicht eines in der genannten Weise gefalteten Verbindungsflansches. Der Kranz 1, welcher Åaus einem Blechstreifen besteht, ist mit einem nach innen abgebogenen Verbindungsflansch 2 versehen, und in diesen Flansch wird eine Falte 3 gepresst. Durch die Einpressung dieser Falte, welche unten eine grössere Breite besitzt als oben, erhält der dem Flansche am nächsten liegende Teil des Kranzes 1 eine gewisse Wölbung. Es können auch mehrere solche Falten oder Wellen 3 nebeneinander in den Flansch 2 eingepresst werden.

Process for producing a curved profile on the rim of sheet metal pulleys.
The invention relates to a method for producing a curved profile on the rim of sheet-metal belt pulleys, which is provided with inwardly bent flanges for clamping the rim on a spider. If one wants to give such wreaths a curved profile, the flanges prevent the parts of the wreath lying next to them from adopting the curved profile. The new method that overcomes these difficulties consists in folding or slitting the connecting flanges prior to pressing the crown into a curved profile so that they allow the parts of the crown closest to the flanges to adopt the curved profile. If the connecting flanges are folded or corrugated, i.e. not slit, this gives the rim a certain curvature in the vicinity of the connecting flanges.
After folding the connecting flanges, the rim is bent to the correct curvature and finally inserted into a bending tool and given the desired shape
EMI1.1
added to the folds.
Figs. I and 2 of the drawing are the side or. End view of a connecting flange folded in the manner mentioned. The rim 1, which consists of a sheet metal strip, is provided with an inwardly bent connecting flange 2, and a fold 3 is pressed into this flange. By pressing in this fold, which has a greater width at the bottom than at the top, the part of the rim 1 closest to the flange is given a certain curvature. A plurality of such folds or waves 3 can also be pressed into the flange 2 next to one another.
