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 manufacturers 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.
