Abstract (en)

[origin: US2014305234A1] A vibration exciter, particularly for a vibration pile driver, includes at least two shafts disposed parallel to one another, as well as at least two imbalance masses, which are attached on one or more of the shafts. A pivot motor provided for adjustment of the relative rotational position of the imbalance masses with regard to one another, includes a pivot motor shaft and a pivot motor housing. The pivot motor shaft is an integral part of one of the shafts, and the rotational position of the pivot motor housing relative to the pivot motor shaft can be changed. The pivot motor is disposed axially offset, in such a manner that it is disposed outside of the regions through which the imbalance masses move.
