Bearing and Shaft in a Screen pkmachinery

There are the simplest of vibrating screens where they have a single shaft with an eccentric mass that rotates to induce vibration. The screen frame is supported on springs to allow it to move freely in a circular motion. The screens have to be inclined as these machines rely on gravity to convey oversized material along the screen.

Noise Causes and Solutions of Vibrating Screen

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.
