Screw shaft
It is a general term for a combination of a spiral blade and a rotating shaft, and has various structural forms. In the screw shaft of the screw conveyor in the industry, spiral blades are mostly made of thin metal plates, and are fixed on the rotating shaft by welding or mechanical means. The screw shaft of a small metering screw feeder often precisely produces a spiral on the shaft. The rotating shaft has two kinds of hollow tube shaft and solid shaft; the hollow tube shaft is made of seamless steel pipe for large diameter screw conveyor; the small diameter screw conveyor uses solid shaft. The necessary strength and stiffness calculations are performed on the shaft. The length of the screw shaft is generally less than 2.5 meters; the screw shaft for packaging measurement is usually a solid shaft with a small diameter and the length is also short.
