Description

Beschreibung Versehiebbare, keillose und elastische, kraftschlüßige Welle%Nabeverbindung für gleichförmige und wechselnde Drehrichtung. Bei den neueren kraftschlüßigen Welle/Nabe-Verbindungen wird der erforderliche Reibungsschluß zur Übertragung des Drehmoneates durch Umsetzung axialer Kräfte in radiale Flächenpreßung erzeugt. Die Aufbringung der Axialkräfte erfolgt über ein oder mehrere Gewinde, die nach dem ersten Setzen. zur sicheren Übertragung des Drehmomentes zweckmäßig einer Korrektur bedürfen. Der Aufwand für Her- . stellung und Zusammenbau ist im Vergleich zu formschlüßigen Verbindungen geringer, aber auch nicht unerheblich, wenn z.B. beim axialen Verschieben die Verbindung ern."äut fixiert werden muß. Description Slidable, wedge-free and elastic, non-positive shaft / hub connection for uniform and alternating direction of rotation. In the newer non-positive shaft / hub connections , the necessary frictional engagement for the transmission of the rotary torque is generated by converting axial forces into radial surface pressure. The application of the axial forces takes place via one or more threads after the first setting. require a correction for the safe transmission of the torque. The effort for her-. Position and assembly is lower compared to positive connections, but also not insignificant if, for example, the connection has to be fixed when moving axially.

Die Erfindung vermittelt eine Verbesserung der eingangs beschriebenen Welle/Nabe- Verbindung, indem erfindungsgemäß eine elastische Schraubenfeder in einen ringförmiges Hohlraum zwischen Welle und Nabe unter Haftsitz auf der Wellenoberfläche axial verschiebbar angeordnet ist. Das eine Ende der Schraubenfeder läuft entsprechend der Schraubencharakteristik frei aus, das andere greift in eine vorzugsweise tangential angeordnete Mitnehmernute oder Ausnehxung der Nabe.The invention provides an improvement of the shaft / hub connection described at the outset, in that, according to the invention, an elastic helical spring is arranged axially displaceably in an annular cavity between the shaft and the hub with an interference fit on the shaft surface. One end of the helical spring runs out freely in accordance with the screw characteristics, the other engages in a preferably tangentially arranged driving groove or recess in the hub.

Die Funktionsweise liegt auf der Hand.
