Two intermediate shafts(4,5) are mounted in the housing(1) to rotate between, and parallel to, the unbalanced shafts(3a,3b). The intermediate shafts are interconnected and positively connected to one or the other unbalanced shafts by means of toothed wheels(7-10,16) so that the one(5) intermediate shaft rotates in the opposite direction as the one unbalanced shaft(3b), and the other intermediate shaft(4) rotates in the opposite direction as the other unbalanced shaft(3a). |
