Bearing and Shaft in a Screen - PK Machinery

2014-8-20  As the shaft rotates, the eccentric shaft forces the frame through the circular motion defined by the degree of eccentricity. The action resembles that of a crankshaft. In order to balance the motion of the frame, counter-balance weights are added to the shaft between the outboard shaft support bearings and the eccentric bearings.

Eccentric Shaft - an overview ScienceDirect Topics

An eccentric shaft rotated by a gear and pinion produces the oscillating movement of the main shaft. The eccentricity causes the cone head to oscillate between the open side setting (o.s.s.) and closed side setting (c.s.s.). In addition to c.s.s., eccentricity is one of the major factors that determine the capacity of gyratory and cone crushers.
