Abstract

Die Erfindung betrifft einen Schwingungserreger zur Erzeugung einer gerichteten Erregerschwingung, insbesondere zum Einbau in einen Vibrationsverdichter, und eine Maschine mit einem solchen Schwingungserreger, mit wenigstens zwei entgegengesetzt zueinander rotierbaren und parallel verlaufenden Unwuchtwellen (10; 20), auf denen wenigstens jeweils eine feste Unwuchtmasse (12; 22) und wenigstens jeweils eine bewegbare Unwuchtmasse (14; 24) angeordnet sind, wobei zur Amplitudenverstellung der Erregerschwingung die Positionen der bewegbaren Unwuchtmassen (12; 22) auf den Unwuchtwellen (10; 20) über eine Stelleinrichtung (2) veränderbar sind, und wobei die Stelleinrichtung (2) zur Amplitudenverstellung ein auf die bewegbaren Unwuchtmassen (12; 22) beider Unwuchtwellen (10; 20) einwirkendes zentrales Stellelement (4) aufweist, das koaxial zu einer Rotationsachse (AS) angeordnet ist, um welche der Schwingungserreger (1) zur Vektorverstellung der Erregerschwingung drehbar ist.
