2. Calculating agitator shaft diameter

2.1 General

See reference [1] [2].

The tree line includes :

  • a solid upper shaft transmitting forces to the bearings and gearbox ;a lower shaft receiving the moving parts (choosing a tubular shaft instead of a solid shaft, for equivalent mechanical strength, saves material and therefore weight, a decisive factor for the agitator's critical speed).

The lower shaft is either "abandoned" or pendular, or guided by the bottom for longer lengths (> approx. 5 m).

The mode of study is that of a cantilever beam, supported laterally by two supports R 1 and R 2 , and axially...
