摘要

Improvements introduced in vibration mechanisms, which, being applicable to those mechanisms that generate two vibration intensities by virtue of using two independent eccentrics, one integral with the rotary shaft and the other mounted in a relative state of free rotation when having a cavity where plays a bolt belonging to the fixed eccentric or a key arranged in the rotating shaft, in any case with the mission of transmitting the mechanical stress of such shaft to the eccentric in question, which depending on the direction of rotation thereof, will add or will subtract the effort generated by it from the fixed eccentric, essentially characterized because they are focused to incorporate in such vibration mechanisms a brake system that acts on the eccentric when the direction of rotation of the tree is reversed and even when laying in operation of the aforementioned vibration mechanism, such system consisting of friction shoes d arranged around the tree and subjected to constant and controlled pressure on the eccentric of relative rotation by means of combined pushers with elastic expansion elements.
