Bearing and Shaft in a Screen

 · 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.

F-Class Vibrating Screen Features Double Eccentric Shaft ...

 · The F-Class features an advanced eccentric shaft design, supported by four high-performance, double spherical roller bearings. The double eccentric shaft creates a constant positive stroke that handle material volume spikes without losing momentum. As the eccentric shaft turns, the screen body is forced to follow the shaft movement.

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.
