ABSTRACT:
A motivational generator which provides vibratory motions for screens, shakers, and vehicles which utilize such motions is described. In one embodiment rotatory motion is imparted to a spinning frame which transmits the motion to two unbalanced chevron-shaped vibratory devices via gears, belts, and pulleys. In another embodiment, the motion of the spinning frame is conveyed to unbalanced chevron-shaped vibratory devices directly through gears. In a third embodiment, the unbalanced chevron-shaped vibratory devices are rotated without rotation of the spinning frame. In the first two embodiments, the spinning frame imparts a gyroscopic effect which stabilizes the motivational generator against vibration in all directions other than the desired back-and-forth direction along the spin axis.
