摘要： A vibration-reducing eccentric weight system mounted to the driveshaft of a screen box in a portable screening plant with the eccentric weight system's center of gravity on the driveshaft's axis of rotation. The eccentric weight system includes a weight that is radially slidably mounted to the driveshaft, but biased so that its center of gravity is spaced from the driveshaft's axis of rotation during slow and no rotation. Upon rotation above a preselected speed, the centrifugal force displaces the weight radially outwardly. This causes a gradually increasing vibration corresponding to gradually increasing distance between the weight's center of gravity and the driveshaft's axis of rotation.

摘要： A vibratory screen separator having a resiliently mounted frame with a screen mounting to receive screens for material flow thereacross. Eccentric weight systems are rotationally mounted with effective axes of eccentric force coincident. The weight systems are symmetrical about a center plane through the separator for uniform vibration thereacross. The coincident axes extend through the center of gravity. A drive is coupled with both weight systems such that the direction of rotation of the weight systems are opposite to one another in one embodiment and opposite in another.

摘要翻译：减震偏心重量系统安装在筛分机的筛箱的驱动轴上，偏心重量系统的重心位于驱动轴的旋转轴上。偏心重量系统包括径向可滑动地安装到驱动轴上的重物，但是偏压使得其重心在慢速和不旋转期间与驱动轴的旋转轴线间隔开。当旋转高于预选速度时，离心力径向向外移动重量。这导致逐渐增加的振动，对应于重量的重心和驱动轴的旋转轴线之间的逐渐增加的距离。

摘要： A vibrating screen separator. The vibrating screen separator may be operated in a linear, an elliptical, or in a transition from elliptical to linear modes of operation. In the linear mode of operation, the screen separator moves along a reciprocating straight line path, and, in the elliptical mode of operation, the screen separator moves along an elliptical path. In the transitionary mode of operation, the screen separator is transitioned from movement along the elliptical path to movement along the linear path.
