ABSTRACT:
A vibratory screening device includes a frame and a screen, supported by the frame, for separating undersize and oversize material. A vibrating device, coupled to the screen includes a first output shaft with an axis of rotation that oscillates relative to the frame. The vibrating device oscillates the screen as the first output shaft is rotated. A driver includes a second output shaft with an axis of rotation that is fixed relative to the frame. The driver rotates the first output shaft. A connector mechanically couples rotational output of the first output shaft to the second output shaft. Preferably, the connector includes a first universal joint, a sliding spline shaft, and a second universal joint. The driver preferably includes an engine, a centrifugal clutch coupled to the first output shaft, a sheave, and an endless belt connecting the centrifugal clutch to the sheave.
