在搅拌轴的设计中，一般考虑四个因素：搅拌轴的扭转变形；从临界转速计算轴

In the design of the stirring shaft, four factors are generally considered: the torsional deformation of the stirring shaft; the shaft diameter is calculated from the critical speed; the combined strength of the bending moment; the allowable radial displacement of the stirring shaft at the shaft seal. After considering these factors, the shaft diameter obtained is only the shaft diameter at the dangerous section. Generally, when obtaining the actual diameter of the stirring shaft, the corrosion margin should be considered. Finally, the calculated shaft diameter is rounded to the existing standard shaft diameter.

In the design of the mixing shaft, four factors are generally considered: the torsional deformation of the stirring shaft, the calculation of the shaft diameter from the critical speed, the combined strength of the bending torque, and the permissible radial displacement of the stirring shaft at the shaft seal. Taking these factors into account, the resulting shaft diameter is only the shaft diameter at the hazardal cross-section. In general, corrosion margins should be considered when obtaining the actual diameter of the mixing shaft. Finally, the calculated axis diameter is rounded to the existing standard axis diameter.
