At this year’s National Manufacturing Week, a new family of locally assembled gear units will be unveiled by Australia’s premier drives solution providers, SEW Eurodrive . Featuring an extended bearing distance (EBD), the EBD MC Compact series of helical and helical-bevel gear units has been engineered to absorb the high bending moments and axial forces that occur in mixer and agitator applications. Like SEW Eurodrive’s MC Compact series, the EBD MC Compact range is fully assembled in Australia.
According to Ian Tribe, SEW Eurodrive, National Product Manager, traditional solutions depend on separate bearings for the agitator shaft in order to absorb axial and radial forces that occur during the agitation process. The EBD MC Compact gear unit assemblies eliminate the need for separate bearings by incorporating an additional bearing housing onto the existing standard bearing housing. This increases the distance between the upper and lower bearings by approximately 50%, adding significant rigidity to the mixer shaft and minimising the axial and radial loads transferred to the gears and bearings.
The EBD MC Compact series consist of add-on components such as stronger bearings, a larger diameter output shaft, and an extended bottom bearing housing. These gear units are designed to handle anything that moves large quantities, whether they are for agitators, mixers, aerators or thickeners.
To prevent contamination of the agitated medium by bearing lubricants, SEW Eurodrive incorporate a ‘drywell’ sealing system to prevent oil leakage at the output shaft in vertical mounting positions.
According to Tribe, the new Australian-assembled EBD MC Compact series is not affected by lengthy lead-times associated with overseas manufacture and shipping.
The Australian-assembled EBD MC Compact series is available in various mounting arrangements and configuration options. Gear units are offered in five sizes, with torque ratings of 16 to 48kNm, suitable for motor powers up to 250kW.
