SEW-Eurodrive is now able to supply an industrial gear unit that offers solutions for mixing and agitating applications with its MC range of extended bearing distance (EBD) industrial gear units.
The company recently supplied the local sewage works in Nelspruit with a 55 kW extended bearing distance (EBD) aerator drive. Raymond Obermeyer, SEW-Eurodrive branch manager, comments that, “The reason the client chose us was our location, stockholding and the excellent service and backup that the customer had received from our branch in the past. This is the first in a series of drives that we will be supplying.”
In process plants, large axial and radial forces occur at the agitator shaft during the agitating processes. Traditional designs solve this problem with separate, external bearings that take on the function of the agitator shaft bearings, a solution that very often proves cost intensive.
SEW-Eurodrive’s new EBD concept extends the bearing span across the low speed shaft and offers stronger bearings within the gear unit itself, which means that in many cases separate bearings are no longer required in the agitator and over sizing of the gear unit can be avoided.
These high torque MC industrial gear units can be used for the reliable operation of mixers, agitators and surface aerators. The powerful and stiff bearings are also suitable for absorbing forces that occur in drives for wet, dry and hybrid cooling towers. The concept is supplemented by an optional drywell seal, which reliably prevents oil leakage at the output shaft together with standardised mounting flanges.
This offers a powerful solution that has output bearings with high load bearing capacity and a reinforced output shaft. Different output flange dimensions can be adapted to the gear unit using clear interfaces. One gear unit can be used for both foot and flange mounting.
