Product name | DIRECTIONAL FORCE EXCITER (CDF) |
Features | Economic and powerful exciter for high performance; Long service life and extremely calm operation; Minimum maintenance requirements; Optimum, application-orientated graduation of exciters; Low operation noise level; 98 % availability; Ideal for use in continuous operation |
Application | Directional force exciters series CDF are used to drive vibrating conveyorsor vibrating screens with exciting forces from 43 up to 1000 kN per exciter.Contrary to unbalance motors, directional force exciters have theadvantage of well defined force flows and defined mechanical loads in thevibrating machine. The vibration data are independent of bulk material loads. |
Construction | Roller bearings and gear wheels are accommodated in a cast ironhousing and are oil-lubricated (oil immersion lubrication). Maintenance islimited to an oil change or an oil-level check, respectively, at the prescribedintervals. The unbalance masses can be changed during shutdown, simplyby installing or removing supplementary masses (steel or lead unbalanceweights). The exciter is run externally by a standard electric motor via a drive shaft.For all directional force exciters suitable drive shafts are available. Frequencyconverters can be used to provide a variable operating speed and force outputas well as a braking function for applications that require rapid or controlledshut down: please consult our technical department for application details. |
Functions | The CDF directional force exciter generates a force F with a sine-shapedpattern along line a-a. The exciter is equipped with two shafts and unbalancemasses. The unbalance masses are synchronized by a built-in gear drive,rotating both at the same speed in opposite directions.The components of the centrifugal forces F1 and F2 working along line aaadd to the resulting force F. The force components perpendicular to that directioncancel each other. |
