Abstract

Bei einem Schwingungserreger mit mehreren Unwuchten in einem Gehäuse, insbesondere für Schwingförderrinnen des Untertagebetriebes, wobei die Unwuchten drehfest auf je einer von mehreren, mit übereinstimmender Winkelgeschwindigkeit angetriebenen Unwuchtwellen angeordnet sind und wenig­ stens eine Unwucht zur Änderung der Schwingung auf ihrer Welle beweglich, beispielsweise schwenkbar gelagert ist und wobei ferner zur Unwuchteinstellung ein Verstellgetriebe dient, welches eine Hohlwelle aufweist, ist erfindungsgemäß vorgesehen, daß als Eingang des gleichzeitig mehrere Un­ wuchten einstellenden Getriebes ein im Gehäuse unterge­ brachter und von außen verstellbarer Schieber dient, in dem zueinander und zur Verstellrichtung parallele Hohlwellen dreh­ bar und schubfest gelagert sind, welche konzentrisch außen auf einer Unwuchtwelle gelagert und von der zugeordneten Unwucht mitgenommen werden, und daß an den Unwuchten und an den Hohlwellen miteinander kämmende Verzahnungen angeordnet sind, die zur stufenlosen Verstellung der betref­ fenden Unwucht bei der Änderung der Schwingung dienen. For a vibration exciter with several unbalances in a housing, especially for vibratory feeders Underground operation, the unbalance rotatably on one of several, with the same angular velocity driven unbalanced shafts are arranged and little least an unbalance to change the vibration on your Shaft is movable, for example pivotally mounted and an adjustment gear for adjusting the unbalance serves, which has a hollow shaft, is according to the invention provided that as the input of several Un balancing adjusting gear in the housing brought and from the outside adjustable slide serves in the to each other and to the direction of rotation parallel hollow shafts are bar and shear resistant, which are concentric outside stored on an unbalanced shaft and by the assigned Unbalance are taken away, and that on the unbalance and meshing teeth on the hollow shafts are arranged for the stepless adjustment of the subject serve unbalance when changing the vibration.
