The aim of the invention is to reduce the vibrational energy and effectively reduce the noise level of balancing shafts comprising at least one counterweight for reciprocating engines. To achieve this, the counterweight (9) has a secondary mass (11), which is supported in the counterweight (9) so that it can be displaced in a circumferential direction. The secondary mass (11) can be displaced on a guide mechanism (12) of the counterweight (9). Said guide mechanism is a curve, the points of which lie at a distance (15) from the axis (14) of the balancing shaft (5) that is dependent on the centre angle (13). |
