Fügen von gebauten Wellen und Verbundbauteilen durch Einwalzen*

Abstract: KurzfassungDas Glatt- und Festwalzen von Bohrungen und anderen Konturen ist ein seit vielen Jahren bewährtes Verfahren, mit dem einerseits sehr gute Oberflächen erzielt werden können und andererseits auch die Betriebsfestigkeit von Bauteilen signifikant erhöht werden kann. Mit dem Einwalzen zur Herstellung von Verbundbauteilen wie z.B. gebauten Wellen können die Einsatzmöglichkeiten des Walzens um einen interessanten Aspekt erweitert werden. Dabei wird mit angepassten Werkzeugen und einem höheren Walzübermaß e… Show more

“…A defined portion of these deformation remains within the hub after the forming and joining process to realize a contact pressure between shaft and hub and thus to manufacture a frictionally engaged connection. A similar behaviour also occurs while joining and forming, e.g., by means of internal high pressure forming or rolling [8,9,10]. In this study, the external contour of the hub is measured at several planes (2 / 6 / 11 mm) using a 3d coordinate measurement device in joined (r h_ex-j ) and separated (r h_ex-s ) state (s. Fig.…”

“…9). friction coefficient ratio = (10) High values of the friction coefficient ratio satisfy the placed requirement for low sliding friction coefficients and high static friction coefficients best. Sliding friction coefficients, which are higher than static friction coefficients, result into a friction coefficient ratio below an amount of one (1).…”
