搅拌器轴的主要作用是传递从驱动装置到叶轮的扭矩。典型的涡轮搅拌器有一个悬臂轴(即在轴的底部不设置轴承)。因而,轴必须有足够的强度使操作不发生故障。轴的设计还应考虑到由于液体作用在叶轮上产生的弯矩。轴和叶轮不应在接近它们的固有频率下运转。
The main function of the agitator shaft is to transfer the torque from the drive to the impeller. A typical turbine mixer has a cantilever shaft (ie no bearings are provided at the bottom of the shaft). Therefore, the shaft must have sufficient strength so that the operation will not malfunction. The design of the shaft should also take into account the bending moment due to the liquid acting on the impeller. Shafts and impellers should not operate at their natural frequencies close to them.
