... for the decrease in coupling caused by the taper. This technique also permits “through the coil” loading or unloading to facilitate fixturing. A similar requirement in the heat treatment of a bevel gear is shown in Fig. 8.9(b) . Here, because of the greater part taper, a spiral-helical coil is used...
