Versatile system equipped with a pair of mechanisms with eccentric elements capable of moving in rotation

A system comprising a frame supporting:

• at least one pair of mechanisms, each comprising:
• a first support shaft, capable of moving in rotation about an axis, equipped with a first toothed wheel and with a first element that is eccentric relative to the axis of said first support shaft, and
• a second support shaft, capable of moving in rotation about an axis, equipped with a second toothed wheel and with a second element that is eccentric relative to the axis of said second support shaft,
• a main shaft capable of moving in rotation about an axis, equipped with at least a main toothed wheel cooperating with said first and second toothed wheels so as to link the rotation of the main shaft with the rotation of the first and second support shafts of said mechanisms, and vice-versa, and
• a rotation driving means coupled to said main shaft so as to rotate same,
• wherein said system further comprises at least one intermediate toothed wheel carried by an intermediate shaft, disposed between said main toothed wheel and said first and second toothed wheels so as to link the rotation of the main shaft to the rotation of the support shafts, and vice-versa,
• wherein said first and second eccentric elements of at least one of said mechanisms are disposed at least partially in a plane of rotation perpendicular to said associated first and second support shafts, and
• wherein, when said system is in operation, positions of said first and second eccentric elements of one of said mechanisms are constantly diametrically opposed to positions of said first and second eccentric elements of the other mechanism.
