VIBRATING SYSTEM

摘要

A swinging system includes two gear trains each having two pinions, a first drive train and a second train driven by the first train, a first pinion of the first train engaging a first pinion of the second train, the second pinion of the first train engaging the second pinion of the second train, each pinion including a disk such that the disk of the first pinion of the second gear train is off-axis relative to the other pinion of the first gear train and one of the two disks includes a slug which fits into a groove arranged in the second disk. Thus, the speed of rotation of the first pinion of the second train varies relative to the speed of rotation of the first pinion of the second train.
