These drive systems are used to provide speed reduction/torque multiplication from the gas turbine output shaft and provide the necessary offset between these parallel shafts in the aircraft. Four different design configurations have been tested in the NASA Glenn Research Center, High-Speed Helical Geartrain Test Facility.
Table 5-1 shows the calculation steps. It will become a standard gear calculation if x 1 = x 2 = 0. If the center distance, a x, is given, x 1 and x 2 would be obtained from the inverse calculation from item 4 to item 8 of Table 5-1. These inverse formulas are in Table 5-2. Pinion cutters are often used in cutting internal gears and external gears.
