vibrating screen deflection

  • Ralph E. BlakeCooper Union

    Static Deflection.The static deflection of a simple mass-spring system is the deflection of spring k as a result of the gravity force of the mass δ st = mg/k. (For example the system of Fig. 2.4 would be oriented with the mass m vertically above the spring k.) Substituting this relation in Eq. (2.8) f

    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.
