The fluidrive
:
The ‘Fluidrive’ is a coupling, which is situated between a driving motor and reduction gear box. Using
hydraulic fluid as the transmission medium, it allows the electric drive motor to reach running speed
before the driving force is passed to the reduction transmission.
The amount of oil in a fluidrive coupling is critical. Reference is to be made to the manufacturer’s
instructions for the amounts to be used in each size of coupling.
Note: fluidrive couplings do not provide a variable speed drive for conveyor belts. Their
sole purpose is to allow the driving motor to reach running speed before any load is
applied.
If there is an imbalance between the ammeters on the two motors driving on a common shaft the oil
levels are to be checked in the fluidrive couplings.
Reduction gear
Reduction gearboxes are used on the belt drives of various configurations, and can be either splash
lubricated or fitted with a forced lubrication system. The reduction gearboxes are fitted with a
Backstop, which is usually mounted internally on the input shaft. In some cases the Backstop is
mounted externally on the intermediate shaft.
