Rotary Force Exciter Cell VZ
.. Long life of bearings
.. Easy repair
.. Low operating costs
.. Very easy and quick exchange of the exciter cell
.. Easy maintenance thanks to oil-lubrication
Application
Schenck Process VZ Rotary Force Exciter Cells are primarily used to drive circular-motion vibro screens.
If the driveline is arranged in pairs, linear-motion vibro screens or
shake-out systems in foundries can also be driven.
The generated exciter forces range between 71 and 493 kN for every driveline.
The exciter cells are designed for 3-shift operation. The shortest main-tenance interval is 1000 operating hours.
The cells are specially suitable for use as vibrators whenever the con-cern is high availability and minimal maintenance and repair effort.
Construction
The oil-lubricated exciter cell con-sists of:
.. bearing box
.. two roller bearings
.. one shaft
.. two unbalance masses
.. cell sealing.
Due to their rugged construction, the cells can easily be replaced, with no need to exchange bear-ings in the field. In contrast to the shaft drives mounted in webs, long downtimes are avoided.
If required, frequency converters for infinite variation of the centrifugal force can be provided for.
Slow-down oscillations of the vibra-tory machine can be reduced to a minimum through the use of braking systems.
Function
The unbalance masses of the exciter cells revolve around the cell axis, generating centrifugal forces with vectors rotating at operating fre-quency.
In no-motion state, the centrifugal force can be varied by application of additional masses.
For driving the circular-motion vibro screen, one exciter cell is flange-mounted to either side web. The two exciter cells are interconnected with the use of an intermediate joint shaft.
The two exciter cells are driven through a stationary standard motor via a universal-joint drive shaft.
In the case of circular-motion vibro screens, the material to be screened is handled by corresponding screen slope.
