Abstract:
1. A vibration generator for a soil compacting device, comprising: a first imbalance mass assembly including a second imbalance mass assembly including an imbalance adjustment device that couples the second imbalance masses of the first and second imbalance mass assemblies in a positively locking fashion so that the second imbalance masses rotate in opposite directions in a coordinated maimer, wherein the positions of the second imbalance masses can be adjusted, using the imbalance adjustment device, such that, when the imbalance effects of the first and the second imbalance masses on the first imbalance shaft compensate to form a minimal imbalance value of the first imbalance mass assembly, the imbalance effects of the additional first and the second imbalance masses on the second imbalance shaft combine to form a maximum imbalance value of the second imbalance mass assembly, and vice versa.
