Advantages and disadvantages of hollow shafts compared to solid shafts: Advantages: ① It reduces the weight of the transmission mechanism; according to the formula for critical speed, the first-order critical speed increases, and by avoiding the resonance zone while still meeting the equipment’s vibration resistance requirements, the vibration of the transmission mechanism is reduced. ②Since the forces are concentrated at the outer edge of the shaft, with no stress applied to the middle part of it, a hollow shaft structure is used; only the wall thickness needs to be determined based on strength and stiffness calculations, which reduces waste. Disadvantage: Due to the need to account for machining allowance, the specifications of the pipe fittings are likely to be limited. The selection principles for hollow shafts are derived through economic analysis: (1) When the diameter

In an enamel-lined reaction kettle, the stirring shaft is generally solid at the upper part and hollow at the lower part, right? How are those two sections connected to each other?

Generally, manufacturers use different designs, but they will all provide markings. The shaft heads are basically all made from solid shafts, but some of those below use not only solid shafts but also steel pipes – it varies.

Why are shaft heads generally solid?

Since the shaft head needs to be connected to the reducer frame, keyways must be machined and the surface requires precision finishing; therefore, it is not suitable to use pipe material for making shaft heads.
