ABSTRACT:
A drive for a particle screening machine or the like in which a bearing support plate is attached to two side walls of the screening machine. A stationary bearing hub is mounted on the support plate in registration with an opening through the plate, and the hub receives and supports a bearing assembly which in turn journals a rotatably driven shaft. A pair of weights are positioned on opposite sides of the stationary support plate and are eccentrically mounted adjacent opposite ends of the shaft with their centers of mass equidistant from the geometric center of the rotatable shaft. The two weights are aligned such that an axis passing through the mass centers of the weights is parallel to the longitudinal axis of the shaft.
