Pedestal Mounted Mixers
The design of large top entry agitators is often driven more by the requirement for the gearboxes to withstand high bending moments as opposed to a requirement for high torque. As the gearboxes are always limited by torque – and output shaft size selected accordingly, high bending moments often dictate the selection of larger gearboxes. For these applications, AFROMIX uses independent bearing members. This design allows the gearbox to be selected on the torque requirements only, while the independent bearing member is accommodates the highloads produced by the agitator, in terms of thrust and bending. These pedestals or bearing members are carefully machined in a single setting to ensure accurate alignment of intermediate shaft, gearbox and lower shaft. Special 5 axis machines are used for this purpose.
