ABSTRACT:
In an eccentric drive system including a rotatably mounted driven shaft, at least one primary eccentric mass fixed to the driven shaft for rotation therewith, an additional eccentric mass mounted for rotation with the shaft in a manner to permit periodic adjustment of the angular position of the additional mass relative to that of the primary mass, the shaft is provided with a shaft portion presenting an outer periphery which is arranged eccentrically to the axis of rotation of the shaft, the additional mass is mounted on the shaft portion to be angularly movable relative to that portion, and the system is further provided with a spring element connected between the additional mass and the shaft for producing a force about the axis of the shaft urging the additional mass into an initial angular position relative to the shaft, and with a fastening unit disposed between the shaft and the additional mass and actuatable between a released position in which it permits the additional mass to undergo angular displacement relative to the shaft and a locking position in which it prevents such displacement.
