In the first report the load distribution along the axis of the pinion in turbine reduction gears in the case of spur gears was treated both theoretically and experimentally. It was demonstrated that the solution by infinite series of an integral equation showed excellent agreement with the experimental data. The present paper deals with the case of double helical gears by means of infinite series as in spur gears, considering the effect of the axial components of the load distributed along the pinion teeth. However, the effect is not so serious and therefore may be disregarded in practice. It is shown that the misalignment of bearings and the error in helical angles affect the load distribution greatly. Especially the difference in temperature rise in the pinion and the gear is important. A difference in temperature by a few-degrees in centigrade changes the maximum load by some 30% or so, increasing or decreasing its value depending on the direction of rotation.
