Abstract
The mechanical vibrator is applied to vibrating screens or other equipment and comprises a bearing housing () to be affixed to a side wall () of the equipment (), to carry a pair of bearings () which support a shaft () having an inner end portion () and an outer end portion () which respectively affix a first and a second counterweight (). The first and the second counterweights () have respective first and second eccentric masses (M, M) of different values and which are positioned and dimensioned so that the first and the second counterweight () generate equal loads on the bearings (). The second counterweight () is constructed to selectively and removably attach a third counterweight () presenting a third eccentric mass (M) maintained aligned with the center line (CL) of the bearing housing (), to provide a variation of the total eccentric mass of the vibrator (V), without changing the balance of the load distribution on the bearings ().
