The shafting shown in Figure 2.51 was taken from a mill transfer chain that was frequently overloaded, causing the shaft (made of low-carbon steel) to fail by torsion shear. It has obviously been loaded in torsion beyond its elastic limit into the plastic range and has taken a permanent set. Since the sprocket and bearing bores are bot easily changed to substitute a larger diameter shaft, what type of replacement shaft will solve the problem?
