ends of the eccentric shaft. Instead of rotating the counterweights, some design provide arrangement to change mass of the counterweights. Generally, power is transmitted from the drive motor to the vibrator assembly by V-belt transmission. The speed of the vibrating screen (vibration frequency) can be adjusted by changing the ratio of V-belt ...
Jun 28, 2018· The vibrating screen works by relying on the centrifugal force of the eccentric block to generate the vibration force. If the eccentric force deforms the eccentric shaft to produce a bend, the relative deflection of the inner and outer bases of the bearing will occur, and the trajectory of the rolling body will change, and thus increase.
