ABSTRACT:
An orbital vibratory mass is used for generating seismic signals and the like. An annular reaction mass is mounted on a crank by means of bearing. The reaction mass orbitally oscillates relative to the axis of the crank shaft without rotating. This reduces the internal forces created in the reaction mass by centrifugal force and enables less exotic, less expensive materials to be used in its construction.
