Abstract
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.
Claims15
A vibration exciter comprising
- (a) at least first and second parallel shafts;
- (b) at least first and second imbalance masses attached on at least one of the shafts;
- and
- (c) a pivot motor for adjustment of a relative rotational position of the first and second imbalance masses with regard to one another, said pivot motor comprising a pivot motor shaft and a pivot motor housing and being integrated into one of the shafts;
- wherein a rotational position of the pivot motor housing relative to the pivot motor shaft is adjustable;
- and
- wherein the pivot motor is disposed axially offset so that the pivot motor is disposed outside of regions through which the imbalance masses move.
