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.
