Abstract

In some examples, an elliptical drive adjusts a phase angle of unbalanced shafts or weights of a vibrating screen. The elliptical drive may include a yoke assembly including four plates that allows relative rotation of two shafts that in turn adjust the phase angle. One of the two shafts may have a pulley drive driven by a motor. The elliptical drive may include two gears intermeshed with each other hand having respective hubs with helical splines that mate with corresponding helical splines of the two shafts. Rotating an actuator rod may cause the two gears to move in an axial direction of the two shafts thereby rotating the two shafts relative to one another which in turn causes a phase angle adjustment of the unbalanced weights or shafts of the vibration mechanism of the vibrating screen.
