Abstract

Verfahren zur Herstellung einer Riemenscheibe Process for manufacturing a pulley

Bei dem im Stand der Technik bekannten Ver­ fahren ist ein "Kollapsen" eines Tiefziehkör­ pers erforderlich, so daß erhebliche maschi­ nelle Aufwendungen notwendig sind. In the Ver known in the prior art driving is a "collapse" of a deep-drawn body pers required, so that considerable machi normal expenses are necessary.

Gemäß der Erfindung wird vorgeschlagen, die Ausgangsmetallronde zu bordieren und an­ schließend die Bordierung flachzudrücken, so daß eine eine größere Wandstärke als die Nabenfläche aufweisende Auflagefläche ge­ schaffen wird. According to the invention it is proposed that To board and to start then flatten the border, so that a greater wall thickness than that Hub surface having hub surface ge will create.
