Motor-Gearbox connection
The connection of the electric motor and the gearbox can be:
- direct connection
- v-belt connection
The advantage of the direct connection (with a flexible coupling or fluid coupling between motor and gearbox) is that it does not require re-adjustment. The disadvantage is that speed-reduction (= speed of the screw pump) can only be done within the available range of reduction ratios from the gearbox supplier.
The advantage of the v-belt connection is that a first reduction can be achieved before entering the gearbox. The actual outgoing screw speed can be exactly matched to the theoretical optimum.
